RE: [SLUG] measuring traffic
This won't work if it is a network with a dumb (cheap/unmanaged) switch. (An old dumb hub/repeater would be fine but almost no one uses these nowdays). You really either need to get access to the gateway (and even then it may not support any decent stats or raw capture) or have a switch that supports port mirroring (where it makes a copy of all the traffic on all ports to a particular nominated port). There is a bad (read crackers) tool called ettercap which can trick all your hosts to send their traffic to another other host by spoofing ARP responses, but in my opinion it will generally degrade your network and hence interfere in your measurement, so you probably should ignore this.

RE: [SLUG] endless packets from my wireless router
As the 1st byte of the destination MAC address is even it is not multicast/broadcast packet, but directed directly to your host. Clearly neither tshark or tcpdump have a dissector for it so it probably is a proprietory heartbeat of some sort. You could verify if it is wireless specfic of you can check if you don't see this when plugged into the ethernet on the netgear port. You could always hassle Netgear to see if they can provide more info on it - it would be hard to write a dissector for it without any information on what it contains. But I really wouldn't worry too much, as it isn't IP it is likely to be link local. Also if your wireless ethernet is like most there are also sub-ethernet frames like beacon packets broadcast every 100ms or so that you won't normally see (as a user) unless your turn your wireless NIC into monitor mode and capture packets with wireshark.

Hi all, I have an HP laptop (Pavilion dv5230tx) which has a very old BIOS installed and I want to upgrade to the latest version. According to HP's change log, Core 2 Duo support wasn't added to the BIOS until the version after the one I have, even though the laptop has a Core 2 Duo processor. I've been trying to get suspend and hibernate working, and I suspect the old BIOS is part of the problem. Hibernate used to work before I had the motherboard replaced, and I'm fairly sure that the old one had a more recent BIOS. I've had a couple of other weird occasional problems which I suspect are due to the BIOS (keyboard not working after boot and mouse behaving very strangely) too. Unfortunately HP only provide updates as a package with a Windows (not DOS) program called WinFlash. I've wiped Windows off the laptop, so my only choices are to reinstall Windows (which means wiping Linux first because HP only provide recovery discs and I don't have a spare laptop SATA drive), or to run WinFlash with wine. I've started the program and it does appear to run, but I haven't been game to let it flash the BIOS yet. Does anyone know whether it's likely to work or if it'll turn my laptop into a brick, or is there another way to do it?

RE: [SLUG] WAN link optimisation
Gavin said :- What I'd _really_ like, though, (and haven't found any explicit references to yet) is like (3) but actually duplicating packets down multiple links, a sort of 'network raid 1' where (3) is network raid 0. In other words, something that transparently splits a stream into multiple duplicate streams down separate links, which are then merged/multiplexed at the other end, and duplicates discarded. Effectively trading bandwidth for latence, given multiple links. Anyone heard of anything at all like that? Or am I crazy? Just a little bit crazy ;-) But actually, if you configured your multiple WAN routers with a single multicast address on their LAN interface (and possibly a a multicast IP address on the LAN ) then you might just have what you want. Each of these routers would receive a copy of the same packet from the LAN (because of the multicast destination). As long as each router has it's own distinct route table it would forward it to the remote end. As Robert said, at least for TCP, duplicate packets being discard already will be discarded by receiving hosts. (Unfortunately this means that your LAN and hosts would need to deal with extra load - layer 3 routers won't detect the duplicates and hence can't do this work for you.) Maybe this solution is also just plain crazy!

RE: [SLUG] WAN link optimisation
I think that the technology Gavin is thinking of is more about economising on the content being sent rather than tweaking TCP parameters. For those that aren't familiar with WAN compression technologies they are probably made most famous by the product coming from Riverbed (but there are many others, including many of the big names in networking). What these do. is basically put a hashing and caching box on each of the link. The sending optimiser computes some sort of hash from the blocks of data payload it sends to the receiver. If the hash doesn't match a previously saved block it just sends it on to the receiver. The receiver saves this new block of data along with the hash and forwards on to next hop recipient. However, if the block matches something previously sent, it merely needs to send the hash (or some other index) to the receiver. The receiving optimiser can then recover the matching block from it's cache and forward it on it's side of the WAN. So effectively this block of data has been able transferred without actually being sent. (This is similar to rsync, the difference is that rsync operates at file level, WAN optimisation interrogates the TCP and UDP payloads directly). Of course the assumption here is that throughout the day (or weeks) there is quite a bit of repetition of traffic. Mail, web and corporate apps, management traffic at a bit level often have the same chunks of data being repeated over again. (Think about a mail with an attachment being sent to multiple recipients, and maybe being forwarded then to others, and finally the attachment being saved on a file server.) The same pattern of bytes is send over the link again and again.) There are other algorithms that involve just sending the deltas, and of course plain vanilla gzip-like compression. In large enterprises, there are some WANs that have achieved over 90% reduction of WAN traffic using these techniques. The whole aim is for the installation of this device to be totally transparent to the applications - apart from the increase in performance and lower link utilisation. I also have had a bit of a look out there whether there is anything like this in the open-source space - and have not found anything. I imagine the algorithms in rsync and squid could be put to play here. The only issue however that I imagine you would probably end up running up against quite a few patents that might cover some of the techniques being employed here. Certainly a project of value if someone has the time!

RE: [SLUG] Printing PNGs with transparent backgrounds
Googling seems to indicate this is a deeper bug than the app (gnome-print was blamed in one report, but it seems deeper than this.). I also had similar problems with modifying the SLUG bootcamp flyer in inkscape - it didn't seem to like partially opaque objects. You may also find that the issue dissapears/changes if you use a different printer, for instance from PCL to PostScript. My simple suggestion would be to create a copy of the png and use imagemagick to add a white canvas underneath - but this probably breaks the fact you don't want to mod the image. At least you could probably script this to be fairly automagic.

RE: [SLUG] New Epson Stylus Photo 1410 - Linux friendly?
Unfortunately I think this is a case of 'overloading' on model numbers. I think you will find that the PSC 1410 is in fact an HP printer (low-end A4 size all-in-one) not an Epson A3 printer. While I totally concur that adding an HP printer on Linux is pretty painless, the experience might not cross-over to a similarly named Epson. That being said, http://gimp-print.sourceforge.net/ release 5.1.1 (only 3 days old!) shows that they have just added support for the Epson Stylus Photo 1410.

RE: [SLUG] AMD based computers.
As has been said, there is no general case that says either way whether Intel or AMD CPUs are better. Certainly for most of last year the AMD based HP servers were much better bang-for-buck having their dual core Opteron. For those interested HP Proliant server model numbers ending in the digit 5 (eg DL585, BL485) are AMD based, those ending in 0 are Intel based). I have a feeling of late that it has swung back towards Intel's favour. Of course there will always be general benchmarks that will have a skew towards one or the other - you really need to specify your exact requirements and an exact point in time before you can judge. Having two near equal sized competitors in the CPU market ensures that progress is aggressively pursued.

For specific examples of machine vs machine you would probably want to look at Toms Hardware guide, etc. If you're looking at higher end / 64 bit server stuff, the word from the various vendors seems to be that although Intel have made a strong comeback in terms of price/performance it does come at the cost of heat dissipation issues and the recent server offerings have pretty much reflected that. e.g. HP are pushing their quad CPU AMD-64 offerings in a 4RU form factor fairly heavily, but you won't find a quad CPU intel 64 bit in anything less than 7 or 8 RU as the intel chips need a fair bit more heat dissipation. How does that relate to home PCs?

I haven't tried getting bluetooth, the modem or fingerprint reader working as yet.

Could it be that there is so much phone home activity on the average Window$ machine at boot time that USERs (who don't have a clue anyway) and MSCE types don't realise that something's amiss? Of course, there are conspiracy theorists who claim that reducing the level of spam is not in the interests of those ISPs and phone providers that charge for traffic in both directions [no names, no pack drill]. But that surely can't be right :-) BTW, I've posted to SLUG-main rather than SLUG-chat because spam can never be OT on a list that itself is so heavily hammered.

RE: [SLUG] change title of xterm window
There is some old magic concerning this that I have mostly forgotten. But as you probably are aware, the title of the window (and all the decoration around the windows contents) is in fact rendered by the window manager. So when an X application starts, it informs the window manager what it would like it's title to be (and how big it needs the windows,etc). These hints can often be ignored by the window manager if it sees fit. There is also some messaging/APIs that allow one to dynamically communicate with the window manager (ICCCM is the old one and it looks like EWMH is something new.) I can remember hacking some C code for X way back in the early nineties' that did things like this with the window manager. Googling though, I found two ready-made command line utilities that look useful xtitle - http://www.cs.indiana.edu/~kinzler/xtitle/ wmctl - http://sweb.cz/tripie/utils/wmctrl/ wmctl looks pretty powerful if you want to be able script a whole lot of things that your window manager should do. (Clearly as already been said, you will probably need to disable/change the dynamic prompt stuff in .bashrc) Interestingly, neither of these seem to be available in standard packages - I guess hacking window title isn't considered mainstream ;-) Regards, Martin Martin Visser Technology Consultant Consulting Integration Technology Solutions Group - HP Services 410 Concord Road Rhodes NSW 2138 Australia Mobile: +61-411-254-513 Fax: +61-2-9022-1800 E-mail: martin.visserAThp.com This email (including any attachments) is intended only for the use of the individual or entity named above and may contain information that is confidential, proprietary or privileged.

RE: [SLUG] L2TPD/IPSec problems - getting there but not quite
A simple debugging technique I have used (short of mangling the source) is to run programs with strace.

Using some scripting in the /etc/ppp/auth-up, /etc/ppp/ip-up and /etc/ppp/ip-down scripts, I can see that the Winbox is being authenticated OK otherwise /etc/ppp/auth-up would not run at all - according to man pppd. That is confirmed by the pppd syslog messages. What I did with the /etc/ppp/ip-up script is to look at ps to see what the status of pppd was before it dies, and I have the following (slightly formatted), using: ps axw | grep -e ppp -e pty 17491 ?

Needless to say there is no indication in the syslogs as to why it is dying, so I can only assume that it is planned death and not an erroneous death.

Back in debian potato there was only one pppd options file so I'm not sure why you have 2 listed?

You should probably have ipcp-accept-local in both options files as well, and it wouldn't hurt to setup ms-dns as the ConfReq from the client is setting these as 0.0.0.0 Valid points. Also, you should probably just have the local and remote IP addresses as 0.0.0.0, (so the line should be 0.0.0.0:0.0.0.0 instead of 192.168.129.1:192.168.129.45), and then in /etc/ppp/chap-secrets have username * password192.168.129.45 as this will then allow you to set the IP address on a per login basis hope that helps tone.

Haven't done any of this much on Linux, but have done similar things with commerical firewalls. Does the log entry sent [LCP TermReq id=0x2 No network protocols running] indicate that there is no interesting traffic on the link. If you have configured the Ipsec to come up on demand then you need to make sure things like routing are configured so that the service still thinks there is a reason to have the tunnel up. Or maybe you just haven't configured the IP parameter for inside the tunnel?

RE: [SLUG] timing out a process with timeout
Malcolm, I was thinking along the same lines. The equivalent in bash is something like:- $ timeout=10; docommand blah1 blah2 blah3 sleep $timeout; kill %% But there is a problem in that if docommand finishes before the timeout expires then you still hang around sleeping. So you need to timeout the sleep process - catch 22. (I think your zsh exhibits the same issue).

RE: [SLUG] NTP problems
H. man hwclock gives some great info of how clocks work in Linux (I hope it is correct!) In particular, the system clock, which is a software clock maintained by the kernel, is only loaded from the hardware clock at bootup (unless you have some wacky script doing hwclock --hwtosys). If your running xntpd, which syncs the system clock with NTP, it will try to update the hwclock every 11 minutes, as well as updating /etc/drift which indicates to the kernel when it boots how far to adjust the system clock. I would suggest to do some logging to see if you can figure out when the drifting is occuring For instance: [EMAIL PROTECTED]:/usr/share/doc/ntp$ perl -e 'while(1) { print `hwclock`; sleep 1 }' Wed 03 May 2006 18:38:33 EST -0.988257 seconds Wed 03 May 2006 18:38:35 EST -0.989062 seconds Wed 03 May 2006 18:38:37 EST -0.987477 seconds Wed 03 May 2006 18:38:39 EST -0.967914 seconds You can also tell xntpd to do a lot more logging.

As far as the specific post to which I responded, my aim was purely to counter Peter's obvious frustration with Linux in general - very specifically his comment why why why can't Linux ever just work? . I merely hoped to demonstrate that it can and it does, at least from my experience with Ubuntu. Don't get me wrong, Ubuntu doesn't always work - I have 3 or 4 open bug reports that I have filed for the current testing release. I also have to compile a new kernel module for my wireless card everytime I upgrade the kernel. Easy to be done (for me at least) - but it is against what I think Linux should be. As far as your feeling that Red Hat specific answers are unwanted, I think that is a shame that you feel that. A mailing list isn't IRC, so even posting a few days after the original question is often still useful if pertinent. (There used to be a I'll post to the list a summary etiquette which my have waned of late). I have installed and used all of the Fedora releases, as well as Redhat back to version 3.0. I have also done most of the SuSEs since about 9.1. I even haved mucked with Puppy Linux of late. So I hardly believe that I live in a Ubuntu monastery. I for one need to know how SuSE and Redhat works. At this stage any Linux work that I do for customers is going to be around the Redhat or SuSE product space (as well as those things with Linux embedded like VMware ESX). I think there is great opportunity for cross-distro understanding. One project that I want to kick-off in fact is a sort of quick reference matrix that describes how a particular administrative function can be done across the major platforms. For instance, all of the distro's use /etc/init.d to contain the control scripts for system services. But the additional feature that Redhat has is the service command which abstracts these when you which manually control the scripts. Similar chkconfig exists in Redhat to define which runlevel a service starts in, yet in Ubuntu you need to use update-rc.d. So sure, you will see some distro religiousity here, but I really don't agree that we are all that bad.

RE: [SLUG] FC5 Kernel headers
I can share your frustration, many many times - yet I persevere knowing that the end mostly justifies the means. As far as packaging goes, however I have learned in the last year or so (having been a Linux hobbyist for about a 14 years now) that Debian distros (in particular Ubuntu) have this thing pretty well sorted out. (I previously shied away from Debian because of the incredibly painful installation process - Ubuntu has fixed this maginficently). To do this exact process (installing Vmware server) a few weeks ago using Ubuntu I did 1. apt-get install kernel-headers which actually just returns a virtual package prompting to select the correct architecture 2. so then apt-get install kernel-headers-2.6.12-something grabs the package and nice-ly puts it under /usr/src/ 3. Then running the vmware install, which all works without much coercion until you find that the gcc that the kernel was built with (3.4) doesn't match the standard gcc installed (4.0) 4. Again this is a pretty simple apt-get install gcc-3.4 5. Running vmware install again and it is all good. I suppose that this isn't automagic, but Ubuntu certainly does a good job of solving dependencies on the fly. Because pretty well all of the known OSS software universe exists as Ubuntu/Debian packages then apt-get removes much of the heartache of trying to pull together dependant software. As far as the issue of kernel versions, CPU architectures and module interaction I do think this is a pain. I imagine that a kernel module could be built that is less strict on having kernel modules build specifically against the headers for the kernel. That is I should imagine late-binding of the modules should be possible in 90% or more occasions. Any idea why this hasn't be explored for the Linux kernel. I can't believe that the hooks that bind modules to the kernel really change all that often, and if they do it should be done exception and probably could be handled by some manner that is less painful than having to recompile the module.

However, now I want to install VMware and compile the modules. Of course this requires the kernel headers, which, even though I ticked all the development check boxes, weren't installed by default and I can't find them on any of the distribution CD's. So a quick uname -a reveals that I'm running kernel 2.6.15-1.2054_FC5smp. So we download and install kernel-smp-devel which creates the directory; /usr/src/kernels/2.6.15-1.2054_FC5smp-i686 I now try to run vmware-config.pl and when it asks for the kernel header source, I point it at said directory and of course being Linux it doesn't work, but returns the error; The kernel defined by this directory of header files does not have the same address space size as your running kernel. Any takers before I run screaming back to MS and admit that Linux was a mistake and that I'll never ever doubt the software from a monopolistic corporate giant ever again?

But Linux itself is Free Software - enforced in court, if necessary. Linus Torvalds is neither unconscious nor stupid. So, is this a Linux user's group? Is it just a I want my software for no $$ group? The hard bit about Freedom is giving it to others, even when you don't like what they are doing. The hard bit about Freedom is NOT controlling others.

RE: [SLUG] Re: [SCLUG] Re: Interesting view
Bohdan, Ithink that most Linux users (fanatics even ) would agree with you that there is a tradeoff in choosing between Linux and Windows. Granted that if I go to the store and buy a big-brand computer it with Windows it will just work. And I can go buy hardware and software and it will just work mostly. So while many Linux'ers might say or think that Windows is "bad", it does basically do the job that it is meant to do. So what do you lose by running Windows? * The main thing for me is it's opacity. After 6 months when my Windows computer all clags up with software that has never been tested to work together, how do I fix it? I might be lucky and be able to uninstall and reinstall, muck with the registry or somesuch. But inevitable I will have to reinstall - and the reason is that so much is hidden from the user. Not being transparent and open may mean I have to pay someone a lot to fix it. I might have to wait for the vendor to come up with a fix, or even have to pay for the upgrade when it comes. I will find it difficult to be able to trace what is going because of the closed nature of the software limiting my visibility. (Yes there are books and specifications and the like, but these only go so far). * Because of the need to support very old APIs (going back to Windows 3.0 even) and without publishing how these things work, the software needs to become big and bloated. It even needs to support previous mistakes made by application developers, and support that software in the same way it used to on every new OS upgrade. Hence it consumes far more resources than is needed by Linux to do the same job. ( I am at this moment running a 2GHz Laptop with WinXP with 768MB - it feels less responsive than a 800MHz laptop with 256MB of RAM running Ubuntu Linux. And this is basically untuned - by judicious decisions on what daemons should run, what kernel functions I really need, you can probably make this better). Unfortunately with Windows it is very hard to know what to tune to fix these issues. * There are lots of applications for Windows that will meet by needs. But unfortunately until I buy them I can't really try them. In Linux and open-source I don't have that constraint. I can also seek to change the application to suit my needs, if directly by hacking the code (or paying someone to do it for me) or indirectly through filing bug requests, and the like. So why is Windows the main game still? * Yes it does work quite well and is feature rich. But this is really because of it being entrenched in the market more than anything. Sadly this means that for games vendors and hardware vendors (that make drivers) that directly need/want to make money from the sale of product, this is where they will be aim for. However if Linux breaks through (and it is IMHO slowly but surely) then this will get there attention. * Because of the market size it is the "safe" and default option for home and business alike. There are load of people that know the quirks of Windows, experienced in supporting it, and so forth. Support services for Linux based systems are still not yet ubiquitous (at least not as accessible as those for Windows). Again, I believe this is changing quickly - many of my work colleagues who had basically only ever worked with Windows (not even UNIX) have now had a chance to play with the modern Linuxes. Many of them like what they see (but of cause the bulk of the work is still for Windows customers - so the cycle must continue for a little while yet) So I will grant you that Linux is still a bit hard. It is a bit like moving to another country where they have a different language, different voltages and power points, and they use imperial nuts and you just bought new metric spanners.( I have pretty well all the hardware working in Linux on my laptop now - it hibernates and wakes-up, my camera, printer and scanner "just worked" - though I had to compile the kernel module for orinoco USB wireless chipset. However I have PCMCIA smart card that will basically never work - because the vendor is closed source only). Yes, I do tweak config files with a text editor. But a lot of that is simply because I like to - and also because I don't probably explore the Gnome menus enough. I am trying to force myself to use the GUI - just so I can be my own n00by. I feel that many of the distros are reaching the "nanna" point - ready for deployment on you grandmother's computer who lives down the coast. But Bohdan, stick in there, it is getting there. Linux is breaking through - quicker than ever as the community grows and people begin to realise it's value. It does take all of us though to make it better. So get in there , join the support forums or IRC channels, write up a blog of how you got something to work, write an update to a manual page, or sit down with a friend who can't affford a grunty box to run Windows and install Linux and watch their eyes
RE: [SLUG] ISP info leakage
Howard, I'm not sure what the issue is. The reality is if that you use your real name and give any indication of your locality then unless your name is Smith or Jones, you probably will count on one hand your matches. For instance I usually say I live in the Southern Highlands, but anyone can find my real number and address without any trouble. If I was an ISP I would be wanting to use geo-focused names for my routers and DSLAMs so that I can easily find correlation of network issues. I am not sure that it is the ISPs responsibility to obfuscate mail headers and the like. And it really would make troubleshooting hard. (I get frustrated enough working with customers that refuse to populate their DNSes with names of their network equipment and such - having to keep a telephone book IP addresses in my head is pretty painful).

RE: [SLUG] Re: pentium M series
All, I just googled for benchmark performance linux kernel i386 versus i686 and found nothing of any import. I am just wondering if anyone has bothered doing this. It would be nice to know what the tradeoff is between performance and convenience of not needing to know the CPU architecture. Using multi-CD distros I would also choose the closest matching kernel, but for my Ubuntu installs I haven't bothered.

RE: [SLUG] Debugging no data for the GNOME weather applet
Mary, I don't use this app, but a quick squizz at the code at http://cvs.gnome.org/viewcvs/gnome-applets/gweather/ would indicate it just uses HTTP like a web browser to grab weather details. My guess is that the server(s) configured for use may have broken or changed format. I would run up ethereal to capture the request/responses it generates (basically try to trigger an update and filter for http in the ethereal display filters). From the responses (either bad, good or non-existent) you may be able to figure out what is going on. Once you know what requests it makes, you might be able to simulate the client by using just a normal web browser). If the app is configurable you may be able make changes there, or even resolve to fix the broken code if necessary ;-) (I'm a bit of a weather junkie as well though I tend to just have quick links to places like http://www.bom.gov.au/products/IDN65092/IDN65092.95765.shtml .

RE: [SLUG] Convert program
Way-back I used to be a fan of the netpbm tools (as opposed to imagemagick) - but I think either of these can do a good job of basic scaling. However if you specificly want to create a webpage in a photo album arrangement, I had fantastic results with the free as in beer Jalbum software - http://jalbum.net . (Yes it is built on Java). I create a CD-ROM photo album of about 300 photos for my school reunion. The way I did this was 1. Used an EXIF tool to edit the comment field dircetly in the jpeg. (This way the caption you want is directly tied to the photo) 2. Organised the photos in a suitable directory structure 3. Told Jalbum to build the album using the chosen skin Hey presto, I had a nicely structured album that had thumbnails so you could select the photos you wanted, a small amount of javascript to drive a slideshow function, and the photos are scaled to fit nicely on the page and had an appropriate caption. (I also added an archive of the original unscaled images for good measure) Regards, Martin Martin Visser, CISSP Network and Security Consultant Consulting Integration Technology Solutions Group - HP Services 410 Concord Road Rhodes NSW 2138 Australia Mobile: +61-411-254-513 Fax: +61-2-9022-1800 E-mail: martin.visserAThp.com This email (including any attachments) is intended only for the use of the individual or entity named above and may contain information that is confidential, proprietary or privileged.

RE: [SLUG] IP Address Source
Simon, anyone know the reason for this? - 'Cause it ain't science! There are a gazillion geolocation databases out there and they all have different information - so why does this happen? IP addresses are handed out to companies and ISPs in fairly large blocks. IANA originates all the IP addresses these are given in very large blocks to regional registries - in Australia this is APNIC. Once these are handed out, they then often get broken up further and distributed to others. (A bit like feeding the 5000!). Companies, like HP, and ISPs, will manage their registered address space in a way that suits their network topology. Unfortunately the only official record would be the registered office address when the initial block is handed out by APNIC (in the case of IP address requested by Australian orgs). My current home IP address is in the 203.217.64.0/21 range - which according to http://www.apnic.net/apnic-bin/whois.pl would put it in Perth (because it is owned iiNet). Now iiNet are under no obligation to tell anyone where they have used these IPs. Unless they bother to fill in the DNS LOC record (which can record long/lat) then there is no way you are going to get the location. That being said it seems that many organisations think that there is value in maintaining a database. A few I have include http://www.ip2location.com and http://www.hostip.info. The latter at least allowed you to change their database entry for your IP. In my case my address showed up as Brisbane, which I duly changed to the town nearest me. The issue of course is that my IP address is dynamic, and at any time iiNet might choose to reorganise their IP address structure. They aren't going to be telling anyone about it. So I guess unless someone can come up with a compelling reason for geolocation, it really is going to be a fun thing to play with, but it isn't going to be very credible. (People claim it would be useful for a Pizza franchise to know which store to direct your order to. Another possible use might be to better perform routing decisions in an environment where a host might be moving, say a VoIP-equipped mobile phone. But IMHO it won't happen as it is to easy to spoof or just the issue that most IP connected devices just don't know where they are) BTW It looks like Moodle might be using http://netgeo.caida.org/perl/netgeo.cgi - because it returned Milton NSW for my address. However you might note from their page that pretty well disclaim any accuracy with their results.

RE: [SLUG] USB Audio Input Devices
If you are serious at doing this right you definitely want to look at semi-pro equipment. I have a TASCAM US-122 that does 2 inputs/ 2 outputs quite well (48KHz sampling at 24 bits). The inputs can be line level or mic level (it uses XLR inputs). The great thing about this unit is the whole unit is powered by USB so you don't need a separate mic preamp, which you would do for any low end usb audio units. (Believe it or not it even provides 48V phantom power for powering condenser mics, all derived from the 5V USB supply!) I would recommend using a Linux distro that is oriented towards audio work such as Agnula or PlanetCCRMA. This will include the apps needed but also makes sure the kernel is set for low-latency etc. That being said, I did managed to get SuSE working quite well as well. The Tascam unit has to have 2 lots of firmware loaded everytime it powers up and this took a little while to figure out. Also certain releases of the ALSA code seemed to break support for my box. If you need to do filtering/effects in real-time it also performs well. By tweaking jack appropriately I could get it have input latency of less than 10ms. (I used it do some nice live echo/reverb effects for my daughter's stage performances). Other popular units used by the Linux audio crowd include the M-Audio Audiophile 2496 and the Edirol UA25. (There are of course many other brands out there, with a large range of prices as well!) If you need more than 2 inputs, all of those makers have larger units (and of course in general you can also use multiple 2 channel units). Of course, recording more simultaneous channels puts more strain on the system (USB, Hard drive, etc) and you need to make sure you don't drop samples mid-recording. It is definitely doable - Digital Audio Workstations are definitely going to be the way forward. As mentioned by Terry, the other alternative is to mix your multiple mics down to just 2 channels using analog mixing equipment. Again like the digital stuff, you get what you pay for. Cheaper equipment often is not as robust (knobs fall off, and sliders don't feel right) or may introduce undesirable noise.

RE: [SLUG] Debian server issues with WinXP
James, I concur with Terry that it might be a permissions thing (or at least whether you are authenticated correctly to have permission.) Though, I do have to say your first test case where you need to attempt to open the file twice seems strange. This would indicate to me some timing issue with authentication possibly. I would have a look at your samba log file (/var/log/samba*) and see if something shows up there. (You can increase the debug level if you think that more info might be useful, http://www.samba.org/samba/docs/man/Samba3-HOWTO/bugreport.html#dbglvl). The specific issue you have with files created by root might be addressed by the info found at http://www.samba.org/samba/docs/man/Samba3-HOWTO/AccessControls.html#id2 595860 (and http://www.samba.org/samba/docs/man/Samba3-HOWTO/AccessControls.html#id2 596278 for that matter) You didn't mention how users are authenticated to samba - if you are using Windows domain/AD authentication (versus local Linux or Samba auth). This might also be the cause of your woes. Again I would expect the samba logs to provide some light. Let us all know how you go.

RE: [SLUG] Technical Help Required
Bill, Googling for your symptoms doesn't show up anything obvious, nor on http://portal.suse.com/PM/page/search.pm. Have you looked at the samba log file? (I haven't got a SuSe box in front of me - but it probably is in /var/log/samba/*). This might show at least where samba is having problems. Also have look at the XP event viewer logs. You might also want to check out the physical stats of the network interface on both boxes (ifconfig eth0 on the SuSe box), and probably your switch as well, while you are doing your file transfer. If your machines are fast (and can saturate the network) and if your physical network is flaky, you might be dropping some session/keep-alive traffic that could be causing you grief. (SMB is a bit sensitive to poor network connectivity). You can always use a tool like iperf to help load up the network and verify how much goodput you are getting between XP and SuSe.

Pete, Is your datalogger ethernet got fixed speed (10M?) or duplex and is it possible that the Unwired modem is 100M only? Mii-diag or mii-tool will tell you what your datalogger is set to. Use ifconfig and look for packet counts (or tcpdump if iy have it on the logger) to see if it is actually receiving anything back from the modem. Of course your datalogger linux may not have all these utils built-in ;-) (Alternatively if you have a spare switch try putting that inbetween the modem and the datalogger and if that makes a difference then you have a physical issue) Regards, Martin Martin Visser, CISSP Network and Security Consultant Consulting Integration Technology Solutions Group - HP Services 410 Concord Road Rhodes NSW 2138 Australia Mobile: +61-411-254-513 Fax: +61-2-9022-1800 E-mail: martin.visserAThp.com This email (including any attachments) is intended only for the use of the individual or entity named above and may contain information that is confidential, proprietary or privileged.

RE: [SLUG] Changing DHCP servers
Simon, There is a reasonably standard approach to this - I have done these migrations a number of times (mainly to perform IP address migration when companies merge or need to move away from registered address space). OK, the problem is how do you introduce a new DHCP scope served by a new server, but that doesn't overlap with the existing scope? Depending on the ratio of number of simultaneous leases to the amount of address space on your subnet you might be able to reduce the size of the existing scope. If the scope on the old server can be resized to less than half of the subnet, you can then introduce the new server with the new non-overlapping scope. You would then just turn off the old DHCP server scope so that any clients that need to renew will be served by the new server when they next renew. (This approach is also used as a simple way to provide DHCP server redundancy - just have 2 non-overlapping scopes on 2 servers). If you don't have sufficient address space to do this then there are two things you can do 1.Reduce the lease time on the old server to say 2 hours. Next time clients renew then they will then be on a cycle to renew every 1 hour. Then, say overnight, remove the old DHCP server and introduce the new with the same scope range. Yes, there will be potential conflicts, but only for an hour (as all the clients will renew in that time). Most clients (well windows ones do) ping or arp for the address they are offered anyway and hence reject ones they see are being used. If you aren't a 24x7 operation this can work well as the machines will sort themselves overnight (or when they boot in the morning). 2. If you absoultely can't have any conflicts and the existing address range is constrictive you may be able to temporaily introduce a new subnet as a secondary address range on the same LAN. This would mean your router (hoping you have a local LAN router capable of reasonable performance) would then perform any routing necessary between the old and new subnets. The new DHCP scope would be based on this new secondary address range. Once you have this in place you could turn off the old DHCP server. Clients on the old and new subnets would still interwork (though via the router). When the clients on the old lease renew, they will then move to the new subnet. Once all the old leases have expired you could then optionally reintroduce a scope on the new DHCP server for the old subnet and basically migrate the clients back in the same fashion. You would turn off the new temporary scope and once all the clients have moved back to the original subnet you could remove the extra secondary address on your router.

I don't know what length the leases are at the moment, that is one of the issues. You should only run one DHCP server on your network/segment/subnet at a time. You would have more then 1 servicing the same ip range. I'd be inclined to setup the new DHCP to take over the role of the old one and then turn the old one completely off, then the new one on. And most machines should attempt to grab the same ip if available, and if not the new DHCP server will issue them new ones based on its leases available. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
RE: [SLUG] Home LAN and video
Bill, I've not actually done direct DVD viewing of the network, but here is a few ideas. Firstly I believe that the maximum bitrate of the video+audio MPEG2 stream is around 6M bits per sec, which is around 600k Bytes per second on the wire. This shouldn't stress any network out (even plain old 10Mbps Ethernet half-duplex could do it at a stretch). Also you should be able to comfortably read at least 10M bytes per second from any disks that you have. You can easily confirm this raw performance by just copying a file that you are sharing (for instance one of your VOB files) to your local machine and working out the throughput. You could also use a tool such as iperf to verify the raw network performance, but I think the copy test should do what you want. The only thing that might be going wrong is that in the file transfer process there is going to be some lag when things get packetised for the network of some 10's of milliseconds. Now normally there is very little lag and certainly no variation in this lag (jitter) when you are reading direct from a local harddisk or DVD. (The test above doesn't measure jitter only average throughput. Iperf can measure jitter, but I don't wouldn't expect it to reveal much on your LAN). From what you are saying, it seems that the problem is that the DVD client application is not network aware (it just sees a file path or drive letter) and hence occasionly when it goes to play a frame of video or sound it just isn't there yet, simply because the server isn't tuned to respond with a repeatable and constant response time. What you really need I believe is to stream your audio or video. This way the application will know the data is coming via a network, expecting delay and jitter, and hence set up a jitter buffer to accommodate for the variation in arrival time of frames. The most common app to do this on Linux is VLC. This can present your DVD as an uncoverted stream (at the same bit rate as your DVD) but still allow the client to deal with network anomolies. Anyway, hopefully someone with some more experience can confirm or deny my suppositions!

RE: [SLUG] problem with wireless
David, The interfaces that Ubuntu tries to bring up at boot time is determined basically by the contents of /etc/network/interfaces. (This is configured by the network GUI tool) You might want to man interfaces and ifup to get a feeling of what is going on. A simple problem that you might have is that your wireless interface (eth1 or whatever) might not be marked as auto. Also of consideration is that depending on how your wireless interface is physically integrated (my HP/Compaq laptop uses a special USB interface) might also determine when it is available to be upped (it might be hotpluggable). Do you have a Function-F2 or somesuch that turns wireless on or off - this might also cause the non-appearance of the device? You probably need to check out the tail of /var/log/kern.log and /var/log/messages for pertinent warnings/errors.

RE: [SLUG] Execution via email ?
Believe it or not, in days when the Internet wasn't quite grown up (early 90's of last century) some people only had email access to the internet. There were actually mail servers setup that you could email an instruction which would 1. ftp download the file 2. break it up into little bits 3. ASCII encode it (probably uuencode, a bit like base64) 4. And then send the bits as separate emails (of course the little bits was to get over restrictions in email size that a lot of people had) You could then download your email and I think then run a script to reassemble the file. (Come to think of it the emails might even have been a shell script - like a shell archive).

Our concerns so far are that although Debian 3.1 would be a good choice, it would probably have to be the DVD version, and this might alienate people that still only have CD drives.

[SLUG] Suse 9.3 Net Install?
Anyone tried out the Suse 9.3 netinst, as per SUSE-Linux-9.3-mini-installation.iso? I got mine from http://ftp.iinet.net.au/pub/suse/Suse/i386/9.3/iso/ and MD5SUM is correct etc, etc. When you have a few source options network or CDROM. Choosing CDROM only lets you go into rescue mode. Choosing HTTP will go out the appropriate mirror, it always is looking to load boot/root , appending it as a suffix to the URL you specify. Now the only boot/root I can find is http://ftp.iinet.net.au/pub/suse/Suse/i386/current/boot/root. The system will try to load it but dies with an error, I think it is actually for 9.2 I have tried it on another machine with the same issue. The structure of all the other Suse mirrors look the same (for instance http://public.planetmirror.com/pub/suse/suse ). Googling doesn't offer an answer. I have had good success install previous versions of SuSe from CD, I thought I would give a direct install a go now that I have a nice broadband connection that allows me zero-metered downloads from the ISP mirror.

RE: [SLUG] running X11 app through Apache
Julio, It seems what you are trying to do and what you are doing it with are orthogonal. The apache web server is design to take requests via HTTP, process them, and spit them out as HTTP. Usually this means a browser sends a GET or POST request for a URL, and the Apache server returns, HTML or XML which the browser displays. X11 clients (the applications) use the X protocol, interacting directly with the X server (which is the terminal). Mouse and keyboard events are encapsulated in X by the terminal, sent to the client, which does some processing, then sends the graphics draw instructions back to the server. This is totally different to the type of interaction and protocol of a web server. Maybe if you explain specifically what you are trying to do, we might be able to guide you.

I've been a fan of Linux for a while, I've got a copy of Knoppix, but recently I was at the Australian Informatics camp and after using Debian for 10 days, it depresses me to come home to my Windows box. I was wondering if you knew where or how I could find some help with getting a copy of Debian with the full KDE, and getting onto my machine so it will dual-boot, Windows or Debian. Niether myself nor my friend (who also went to the camp, despises Windows and wants to get Debian as a dual system) can download the complete disks, and neither of us know how to safely install it on a partition so it won't stuff up Windows, and Windows won't stuff it up.

In simple terms, it occurs where an attacker is able to exploit a programming flaw that allows a program to accept more data then it is really designed for. Most programs that accept input from the network (or other input device) will prepare a buffer, some memory space, to accept that input. If the program is written correctly it should validate the input or use other some mechnanism to ensure the input does not exceed the size of the allocated buffer. However, in certain program architectures, data that is accepted which is more than the buffer can handle could overwrite existing program data. If this excess data is craftily designed, the program can be tricked to then execute this excess data (which is now not just data, but now part of the compromised programs instructions) and will run with the priveleges of the exploited program. The excess data is a small chunk of compiled code specifically designed to run on the target platform - it is usually caused by inserting a jump in the normal code instructions. In the Code Red example below the attacker is sending a GET request to a web server. In a vulnerable IIS web server, the URL specified in the request is much larger than it expected. This data ends up in the web servers running program space, and is executed by the target system. The Code Red worm can then do it's job to continue to seek and replicate itself. Code Red of course only can affect unpatched vulnerable IIS servers. Of course, there have been plenty of buffer overflows identified in Linux based applications, Microsoft-based systems are just a bigger (and presumably more lucrative) target. Most program development projects actively check their code for the possibility of buffer-overflows - hopefully they find the holes before potential attackers do. There is also work being done on various hardware and software architectures that limit the ability of unauthorised code to execute on a platform. For the average user, provided you limit your internet facing profile using a firewall configured to only let necessary traffic in , and are vigilant in patching your systems, you are as safe as you can be. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Howard Lowndes Sent: Thursday, 7 April 2005 7:30 AM To: Phill Cc: slug@slug.org.au Subject: Re: FW: [SLUG] Possible hacker Attempt Phill wrote: I am also curious.

RE: [SLUG] a nice question
I have a very easy fix for this - you want to limit the rate at which read or write the data. As tge gzip/tar process will then have lots of breathing time for CPU/disk intensive operations: There is a very nice pipe viewer/rate limiter called pv 1. So write your command so it uses stdout to write (or read) the file: gzip -c big_file small_file.gz 2. Now use pv to view the rate at which it runs gzip -c big_file | pv small_file.gz This will show output like:- 3.33MB 0:00:02 [ 1.7MB/s] [ = 3. Now use pv to rate limit gzip -c big_file | pv -L 100k small_file.gz You get output like this 292kB 0:00:03 [ 98kB/s] [ = As gzip is only allowed to write 100kB per second it continually yields CPU cycles back to the kernel.

RE: [SLUG] top command - looking for a site that explains the runningprocesses
For non-interactive system processes you should google for documentation that describes init, the grand-daddy of all processes, and /etc/inittab and the scripts in the /etc/init.d directory which effectively configure init. (chkconfig also drives the /etc/init.d configuration). Of course each of the services/processes that is configured here spawn subsequent processes - pstree is an excellent command to show these relationships. Finally cron kicks off scheduled processes at various times. (Each distro has different ways of managing these through the GUI so you need to look at the System Admin section of your distro manual). Depending on what you do interactively of course will also determine what processes run. The terminal, Gnome and KDE environments all kick off processes at various times to support shells, toolbars, panels, monitoring etc. Unfortunately there is not really a single authoritive place to look at why something is running. top is a great window into the environment, but unfortunately you will need to do a little hunting to determine the root trigger/cause. That being said, the great thing about Linux is that it CAN be determined. I have found that even experienced administrators in another unnamed environment often can't clearly explain why something is or isn't running. (Hence the current dire issue with spyware, trojans, etc). While everything in Linux may not be clearly documented in plain English, somewhere the code is available for perusal - though this may not help the newbie.

If you have more than one PC that you want to display then you might also want to consider a KVM switch.

Thanks Martin, but my situation was just a couple of white box PCs at home, both of which have had their monitors die. So I just wondered if there was a way to feed the RGB cable's output as an input to another PC (a laptop), to display the signal. Since all that's needed in this circumstance is the video signal, I thought there might have been a way to grab the video as *input* from the laptop's external video connector - but I guess I'm showing my lack of electrical knowledge, and the RGB is one way, not bi-directional. luke -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

RE: [SLUG] NTPD FC3
Are you sure it is rejecting the source port? From reading the doc the default should be that it accepts from any port. Have you checked NTP version support - I imagine the FC3 ntpd is by default version 4 and hence your older clients may not support that. Try setting version 3 or 2 in the config. If you really think you that it is rejecting the non-123 packets then I guess you could possibly use NAT/masquerading on the server for those specific hosts.

RE: [SLUG] Mega X machine spec - ideas?
You probably want to use sar or the like on your existing machine to get a baseline understanding of CPU/disk/network etc. Hopefully you can extrapolate requirements from that. If the application onf the server is particularly critical you might want to consider using a hardware loadbalancer to front a server farm with a pair or more servers. This will give redundancy as well allow you to scale as performance requires it. You could even consider using blade servers if space/managability is an issue.

RE: [SLUG] Lusers grabbing IP addresses - stopping them
The correct answer is that DHCP (and bootp) and in fact any simple protocol that uses broadcasts to discover resources/services that it will rely on need to run on a secure network infrastructure. This means physical access as well as having control of the devices that use the network. (As an example, Bugtraq this week has a discussion around the fact that Altiris clients (software deployment ala Ghost) by default trust a response to a multicast to find a software load server. Hence a spoofing server can easily own the client machines) There are usually software means to detect illicit use of IP addresses, etc as stated by others. These are probably good to use in most environment where your threat is dumb/smart users mis/malconfiguring their machines. Also you should separate critical network resources on a separate by an IP routing switch from your clients. This way clients cannot steal say the server IP address even if they try. If DHCP clients are on their own subnet/VLAN then they can only tread on each other's toes. If you really concerned about access to the network at Layer2/3 (before operating system authentication/encryption comes into play etc) then you need to look at things like IEEE 802.1x. (Yes, x is the working group not a placeholder). This enables a smart LAN switch to authenticate the client before it is allowed access to real network resources. (It also allows the client to authenticate the network to assure that it is in fact connecting to the network it expects to be before it starts using it - very important in wireless environments) Regards, Martin Martin Visser ,CISSP Network and Security Consultant Consulting Integration Technology Solutions Group - HP Services 3 Richardson Place North Ryde, Sydney NSW 2113, Australia Phone: +61-2-9022-1670 Mobile: +61-411-254-513 Fax: +61-2-9022-1800 E-mail: martin.visserAThp.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Howard Lowndes Sent: Thursday, 28 October 2004 10:33 AM To: Ken Foskey Cc: slug Subject: Re: [SLUG] Lusers grabbing IP addresses - stopping them On Wed, 2004-10-27 at 23:30, Ken Foskey wrote: On Wed, 2004-10-27 at 16:29 +1000, Howard Lowndes wrote: If you are running a DHCP server on a network and have a block of IP addresses which you make available, how can you stop a (reasonably) knowledgeable luser from explicitly grabbing an address from that block by explicitly configuring their box with that address, thus preventing that IP address from being recorded in the leases, and hence you not immediately knowing that that box has been attached to the network. arpwatch ?

RE: [SLUG] Network Testing
I know it might seem to be a sledgehammer to crack a nut, but Nagios is a good service oriented monitoring tool that is OSS. BTW Most load-balancing devices that need to do service monitoring simply open the service port and try to get a basic response that proves that the service is up and operating. For instance for a web service with a DB backend you might first do a simple HTTP GET of a static page (and compare with a known result) and then do a simple DB query via the web service to make sure the DB is running. Clearly some sort of algorithm needs to be determined of when to declare a service down (and when to declare it available again).

RE: [SLUG] Network Testing
One thing about pinging a providers gateway is that for the router to respond to the ping requires it's management functions to actually process this request. Usually such functions are quite low in the priority list (the routers primary function is to forward packets to the destination by the optimal path, and not respond to ICMP requests). Also a single ping is a single IP packet. IP is by nature unreliable in that instantaneous congestion, link failovers, etc will cause individual IP packets to be lost. This is why you need protocols such as TCP to provide reliable transport on top of IP. Thus loss of a single packet does not significantly affect performance for most apps. (Loss of many packets of course will). For instance when I have investigated networks for issues supporting Voice over IP I have sent regular small bursts (say 10 pings over 1 seconds at 15 second intervals) to understand if there are is major issue with the network having burst losses. While an individual packet loss is not likely to affect an app at all, a burst loss often will. (VoIP is of course very sensitive to packet loss as there is no recovery mechanism other than playing silence). My suggestion if you are concerned that your ISP is not maintaining a good level of service, rather than ping their gateways I would do HTTP GETs to 3 or 4 major web sites. Pick say one hosted by your ISP, one or two local to Oz and one or two that are international, and are going to pretty well always be available. If you measure the response time to get a small static file (say a GIF) you can then get a feeling of the performance level through your ISP and their connection to the internet. You of course need to figure how to interpret response times across the different servers. This way you are not (falsely) interpreting a one or two ICMP losses from a router as failure. Anyway just a few thoughts for discussion.

I've taken a quick look at this, but *for my purposes* I can't see it's an improvement on just pinging. Problem: I've changed providors, and suddenly I'm getting outages that THEY can't explain. We all suspect routing issues upstream, but no one seems to be able to put a finger on it. My current solution: Run a script once per minute which pings Powertel's border gateway (border-gw015-ge02.powertel.net.au) and emails me if two consecutive pings fail. Result: Averaging one failure/hour.. sometimes several consecutively. Question: Is it reasonable to expect ping -c 1 to be a true indication of the network status? I understand that ping waits one second before giving an error. That sounds like a network problem to me. The normal ping is about 7 ms. I ran this same script for 3 years with my previous providor (optus) and it only complained on the rare occasions that there was a genuine, serious problem. BTW: Nagios looks terrific, but I have complete control of the various services so they are less of a problem for me. It's the network status that's giving me grief. As far as I can tell, to prove the network is up Nagios basically does something similar to what I'm already doing. David.

RE: [SLUG] /etc/profile
Short answer is :- In every running shell arrange to execute . /etc/profile, which sources the script in /etc/profile. Long answer :- Don't follow the short answer unless you know what /etc/profile does. /etc/profile is normally run once (and once only) by the shell when it initializes. Clearly some commands that are in /etc/profile (or run by /etc/profile) may not like being run twice. Simple things line cd $HOME which is sometimes in /etc/profile may also not what you want to do to a running shell. Also bear in mind that you can't force changes onto a running shell - it is a simple sandbox that needs to invoke commands to change its environment, rather than have external commands change the environment from the outside. Of course all newly launched shells will use the new /etc/profile. (There is another alternative to the short answer and is running exec sh in each shell which causes a reincarnation of a new shell in the current process. This will kill any background running processes as well. So this is effectively the same as killing the old and starting a new shell) (Big disclaimer here as I am not a shell guru, but hopefully you get the gist) Martin Visser ,CISSP Network and Security Consultant Consulting Integration Technology Solutions Group - HP Services 3 Richardson Place North Ryde, Sydney NSW 2113, Australia Phone: +61-2-9022-1670 Mobile: +61-411-254-513 Fax: +61-2-9022-1800 E-mail: martin.visserAThp.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Luke (Terry) Vanderfluit Sent: Monday, 16 August 2004 1:52 PM To: [EMAIL PROTECTED] Subject: [SLUG] /etc/profile Hi, is there a way to activate changes made to /etc/profile other than rebooting the box?

RE: [SLUG] Home LAN IP details
Usually each of your PCs will register their hostname with the DHCP server when they ask it for an IP. Your modem/router will probably have a web page (look for status or somesuch) that will reveal the names, IP address and MAC (ethernet) address it knows about. Often they also act as a DNS and as such will also reveal the name to IP address mapping via DNS. You can query this with the command nslookup hostname router_ip. A lot of these router/modems even support WINS (the old Windows dynamic name service), you can query this with nmblookup -U router_ip -R hostname. BTW Almost certainly the IP allocated is not associated with the physical port. Usually allocation is simply out of the next one available in the pool of addresses for DHCP.

RE: [SLUG] Developing FOSS while employed developing proprietarysoftware
My company basically owns my IT brain while I am employed for them, so anything I develop in an area of HP's business is considered theirs. This might seem restricting to some, but they do have a specific program which allows HP employees to register their involvement in OSS projects. Involvement of course if reviewed to ensure that investment in development of proprietary IP (intellectual property) isn't fritted away. I imagine community benefit versus opportunity to sell a product is always the consideration. Approved projects of import are recognised by linking at the http://opensource.hp.com site. Also employees are encouraged to submit any inventions they have which are reviewed and submitted for possible for development and subsequent recognition. I would imagine that most enlightened companies might have a similar approach. Assuming that your employer is providing you opportunities to develop and grow your knowledge and skills (and not stifling them) it seems only fair that they own a the IP in your head, and should get first option as far as its use.
