If you want the launcher to only display in Xfce then set this in your .desktop file: OnlyShowIn=Xfce I've already found a way of mouse clicking that pops up a small window with small text entry boxes in it, but I have no idea what to type into the boxes. And, for all I know, my mouse clicking is not at all any part of getting the mixer.app .deb to play nicely with xfce. Also, mixer.app may not be the best solution for my screen real estate problem. Alternatives for a smaller area mixer graphic will be happily entertained. Do you really need a mixer, or do you just need a way to control volume/mute? If the latter, you could bind some keys to the XF86_Volume*-keys (and mute) if you don't have multimedia keys on your keyboard, Xfce recognizes those and adjusts the volume accordingly. There are probably command line tools that will adjust the volume by a certain number of steps that you could use for this, also, although I don't know of any. If you want a graphical mixer, I found wmmixer - is that the same as the one you are talking about? Just a thought. :) Petter -- I'm ionized Are you sure?

Well, yes and no. We *do* know that the status has changed from mandatory to optional, but whether hardware manufacturers will actually remove the ability to turn Secure Boot off remains to be seen. Yes. I read that. Wonder what Microsoft has up its sleeve? If I were to guess, this is in preparation for at some point in the future requiring Secure Boot to be used, without the ability to turn it off. My guess as well. Anything to make Windows more convenient to use than installing another OS. But you gotta think like a Microsoft lawyer here: But, your Honor, you CAN install Linux on the machine. Just follow these simple 389 steps. No problem. ;-) You know, think of the children!. Maybe, this is indicative of W10 being even more insecure than previous Windows' OSes. Secure Boot itself is not actually such a bad idea, in some circumstances it might be nice to have a fully signed chain. IMHO. But it seems that Microsoft has co-opted it for their own use. They're the only ones making and selling the signing keys aren't they? Shouldn't those security keys come from an independent, unbiased provider? One that Microsoft has to get their signing keys from, too. From what I understand, basically anyone can put their signing keys in the firmware. Part of the criticism is that Microsofts keys are already in it, making it difficult for anyone else, and without installing your own keys, you must use keys that have been derived from theirs. I may be wrong on this, I don't fully understand it. Canonical will also enforce Secure Boot in the future, they claim, and they are trying to get vendors to include their keys. I am more worried about distributions like Debian. Fedora has the backing of RedHat, so they will get keys (if they haven't already), SUSE has cash, but I have no idea about Debian. At some point Canonical would probably have helped them out, but I think that time has passed. They are mostly looking out for themselves these days. With Snappy, I don't even know if they will be based on Debian for much longer. And what about all the other distributions? Slackware, Gentoo, etc? There is no way all of them will be able to obtain keys. I agree; an independent signing authority would be the best, but I'd also like to see the ability to implant your own keys in the firmware. And even better, to remove them, so that I could delete the MSFT key. As mentioned, the Linux Foundation is looking into obtaining a key that can be used to sign for distributions. The problem is that MS is able to revoke keys at any time, and that would revoke all the Linux distributions at once. Eggs - basket. Hardware manufacturers will have to take into account the fact that there are a large number of people and organizations that run their machines without Windows, so I don't think there will be a lack of machines that can turn Secure Boot off in the near future. Have you forgotten about Asus and its $99 EeePC of a few years ago? It only ran Linux. To keep the cost down. No OS license needed. It sold very well, but was only a small part of Asus' Windows PC market. Microsoft still threw a hissy fit and threatened to revoke Asus' Windows license, if they didn't cnange the EeePC so it could run Windows XP. Production on the EeePC ceased, and a year later a new EeePC debuted running a stripped down version of XP. But now it cost $199 not $99 whether it ran XP or Linux. And the consumer got screwed. MS didn't care. They got their unit license fee. Ah, the MS tax. Microsoft holds that Windows license over manufacturers like a battle axe. If manufacturers don't go along, off with their heads! Microsoft can (and does) get almost anything it wants, and they've got a legal department that enables them to get away with it. I really, really wish Apple would release OS X for commodity hardware. That could probably give MS a (little) run for its money in the home market. Because let's face it - Linux isn't going to compete with them for the ordinary user anytime soon. Neither are the BSDs, or HURD, or Haiku, or... (Yes, I know Apple will never do that.) But will it become something to watch out for when buying new hardware? Most certainly, at least for a period of time. I have a sneaking suspicion that it might become a bigger problem for laptop users than for desktop users, although I'm unable to back that up.

This is often used for cracking the web site but could also be used for leaving files such as a compomised 'ls' around too.

With LD_PRELOAD_PATH is almost as good and has all of the same dangers. This could potentially through a sequence of missteps become a remote root compromise to the system. OK, this is veering off-topic - apologies in advance. From what I understand, LD_LIBRARY_PATH contains additional places to look for libraries that aren't in ld.so.conf. From ld.so(8): LD_LIBRARY_PATH A colon-separated list of directories in which to search for ELF libraries at execution-time. Similar to the PATH environment variable. Ignored in set-user-ID and set-group-ID programs. But what order is this information parsed in? Does LD_LIBRARY_PATH override ld.so.conf? Ie, could I place a modified version of a library somewhere, point LD_LIBRARY_PATH at it, and every binary that is linked toward the original library will run functions from the modified one, or would I also need to remove the original library, so that only the modified one is found? The danger would be much clearer if it overrides, since if it doesn't you will probably notice that the original library has been disabled. Am I even on the right track, here? Some of us would say it is unlikely to happen to *us* but we might all agree that it could happen to someone else. A potential if unlikely exploit. Yes, it would never happen to me.

That last one, would that be limited because of CPU power? That too. You cannot extract that much juice from a single-core ARM5.

Any value above 1500 is non-standard (so nothing is guaranteed) A case study (that particular NIC claims to support MTU of 9200 in dmesg): # ip l s dev eth0 mtu 1500 # ip l s dev eth0 mtu 9000 # ip l s dev eth0 mtu 65536 RTNETLINK answers: Invalid argument Of course, for this to work it would require to increase MTU on every host between your two, so that's kind of a last resort measure. Well, both hosts are connected to the same switch (or right now, to the router, but I could easily put them back on the switch if that matters). One of the hosts would not accept a value larger than 7152, but it did have quite an effect: I now get up to 880Mbps :) Will this setting have an impact on communication with machines where the MTU is smaller? In other words, will it have a negative impact on general network performance, or is MTU adjusted automatically? And what is the appropriate way of setting it permanently - rc.local? Also, the machine with the Realtek PCI adapter has a Marvell 88E8001 on the motherboard, but I haven't used it for years since there were once driver problems. Those are probably fixed now, I will try that once I can. Didn't think of it before. If the Marvell NIC uses sky2 kernel module - I would not even hope.

Try to add the ones I listed (I'm not sure about the order, but probably the order I listed them in) before the line that loads snd-hda-intel. Nope. still nothing. #tail -f /var/log/kern.log, this last try, had a line after the modprobe that was disturbing, but I still got sound: May 24 06:50:43 persephone kernel: [ 265.501340] sound hdaudioC1D0: hda-codec: out of range cmd 0:5:707:ffbf I'm not sure what this means, but a quick search leads me to believe it is Mostly Harmless.

As you can see, the second is size, and in this example there is nothing under Used by except zeroes. The zero means that no other modules depend on this one. If there had been dependent modules, this row would list the number of dependants, and then a complete list of them. You can then use this information to track which modules are needed for a specific module to load. Like this: Module Size Used by snd_timer 32768 2 snd_pcm,snd_seq This means that there are two modules that depend on snd-timer - snd-pcm and snd-seq. snd-timer then have to be loaded first before either of those can be loaded. You can then backtrack through the lsmod output to see what other modules snd-timer depend on (by grep'ing for it), for instance, and thus see the entire chain of modules that are required for any specific module to function. All of this should be handled automatically, but there are occasions when a module needs to be force-loaded. Is that any clearer? I can't explain it any better in English, and I expect an explanation in Norwegian wouldn't help you very much :) In regards to your problem, I really don't know why snd-hda-intel won't load automatically for you. It might have to do with recognition of your hardware, that it isn't probed correctly or something. The easy solution is probably to just add modprobe snd-hda-intel to /etc/rc.local and leave it at that. If you really want to follow up on it, you would need to grab the details of your sound hardware from lspci and do a few web searches. If nothing comes up, then file a bug report.

IP performance question
I've been trying to improve NFS performance at home, and in that process i ran iperf to get an overview of general network performance. I have two Jessie hosts connected to a dumb switch with Cat-5e. One host uses a Realtek RTL8169 PCI controller, and the other has an Intel 82583V on the motherboard. iperf maxes out at about 725Mbps. At first I thought maybe the switch could be at fault, it's a really cheap one, so I connected both hosts to my router instead. Didn't change anything, and it had no significant impact on the load on the router. I can't try to run iperf on the router (OpenWRT), though, as it maxes out the CPU. Should I be getting more than 725Mbps in the real world? Could there be a driver issue, or some settings that aren't optimal? Unfortunately, these are the only two hosts I have with Gbit interfaces (except the router), so I can't test with another host. Could this be a MB/MiB issue? The iperf man page doesn't say which it reports. (Well, it says Mbit/Mbyte, so I assume it does not mean MiB) Am I missing something obvious? I'm no networking guru, but I'm hoping to learn something from all of this, so all input is appreciated. Petter -- I'm ionized Are you sure?

Can Debian Linux 6 LTS be installed on a system that already has Debian Linux 7 installed on the system, so as to have both versions of Debian Linux, concurrently installed, and have the option of being able to boot into either of those two operating systems, using the Legacy boot system (it also has Ubuntu 14.04 LTS installed)? If both Wheezy and Trusty are installed in legacy mode the bootloader should see all of them. Dependent on your needs, an easier way might be to just spin up a VM or three with the systems you use the least. KVM is a wonderful thing. 2. Can Debian Linux 6 LTS handle a GPT HDD, with partitions of up to about 100GB, or does Debian Linux 6 LTS have a limit on the size of the disk partitions that it can handle? Shouldn't be a problem. I think the limit on MBR disks is 2 or 3TB, and Squeeze handles GPT anyway. The limit on partition size with GPT is not practically reachable on a laptop today, but go ask Google if you want to know what it is. 3. Can Debian Linux 6 LTS handle 32GB of RAM, or, does Debian Linux 6 LTS have a limit on the amount of RAM that it can handle? It would depend on the kernel and userspace, but it has an amd64 port, yes. There is still a limit on how much RAM it can address, but it is not likely to become an issue, as it is most likely far, far more than you can fit in your laptop. Petter -- I'm ionized Are you sure?

What steps do I need to take to get it to load at boot again? Re-Installing ALSA does nothing, of course, and I guess I have no Google skills, because all I can find with Google is advice to reinstall ALSA. Take a look in /etc/modules-load.d - you can add a file called, say, sound.conf there with the contents: snd-hda-intel That should load that module on boot. I haven't tested it, as I've never had the need to force a module to load in recent years, but it should work. Petter Didn't work. Nor did adding snd-hda-intel line to /etc/modules. Those two do the same thing. Any more suggestions? I'm running Jessie. Have been since Jessie was testing, about three months after the release of Wheezy. So it's seen a lot of changes, the biggest of which was the transition from sysvinit to systemd. I should have fixed it a lot sooner, but as long as I could fix it by running modprobe, I wasn't in a big hurry. Anyway, if this had worked, it feels like a workaround, and isn't really getting to the actual cause of the problem. So, any more suggestions are welcome. Well, maybe it is dependent on another module that for some reason doesn't get loaded automatically when you try to load snd-hda-intel, but that has been loaded later in the boot sequence? (Although I have difficulty imagining how this could happen). Try to run lsmod | grep snd, and add the modules that snd-hda-intel depend on before the line loading it in the relevant file in /etc/modules-load.d or in /etc/modules. As a last resort, you could add a line with modprobe snd-hda-intel to /etc/rc.local, but none of these suggestions do more than work around the problem, as I am at a total loss as to what causes it. I also use snd-hda-intel on my Jessie system, and have never had to force it to load manually. To actually fix the problem: What do you see when you go through the logs after booting, related to sound, and when you load the module manually?

While I do recognize there are differences between SAS and SATA, do you really need SAS in a home setting - for a media library? SATA may be the simplest/cheapest solution, to my way of thinking. Not so much beyond about 10 drives. That said, this system was eSATA based for a long time, but it has been having issues. In my efforts to troubleshoot the problems, I converted my 20 drive chassis from eSATA Port Multipliers to multi-lane. It has solved some of the issues, but not all. Wow, you certainly have a far bigger media library than me, unless you are using a ridiculous amount of tiny disks. :) Again, I agree. In this scenario, I would find a couple of controllers that would seem to suit my purpose, and contact the manufacturers directly with very specific questions. That is much easier said than done. Even companies who have people manning the phones often have people in those positions who are clueless beyong what is already on the web. Don't phone - email. Or, better, write an actual letter. The drones on phone support are so often useless, but they do have the ability to forward questions to people who can actually answer them. It is more likely that they will do this with a mail request than a phone call. If they are simply re-branding something that is actually made by another manufacturer, then contact _them_ directly. Go to the top, and make lots of noise. It's the only way to be heard by some of these people. Be sure to let them know that you *want* to be a paying customer, if they can only clarify what they are actually selling. One of these questions would be whether or not the controller is supported by the Linux kernel itself, The kernel is not so much the issue. Most cards are supported out of the box by the kernel on Jessie. It is the management software that is usually a problem. If they don't want to bother to support all sorts of different distros, then they should provide open source management software. I agree. And be sure to _tell_ them that. Make noise when they don't support Debian. If nobody does, then why should they support it? I assume it is not simply a matter of converting the package from RPM with alien, or manually extracting things and hack them together to get a working binary? No, it should not be necessary, but it is something to use against them when asking why they don't support one of the biggest distributions out there. If they already have code that runs on Linux it shouldn't be that big of a deal to run on multiple distributions. _Supporting_ all of them is another deal entirely. Another thing you could try, is to see if Canonical will back you. They may have some clout to get the manufacturer to provide a .deb, and this sounds like the sort of hardware they would want to see supported. Yes, they will probably ask for a package for Ubuntu, but it will get you a lot closer than where you are now. They might even be willing to ask for a package that also runs on pure Debian, as it shouldn't be too much effort to make sure it runs on both. I know that Canonical has worked with vendors in the past to get them to support their distribution, so it shouldn't be a new problem to them. Petter -- I'm ionized Are you sure?

A DVI-I KVM will carry both the digital and the analog signal, so you can use a DVI-D cable to connect it to a DVI-D screen - it just won't carry the analog signal, which you wouldn't need or be able to use anyway. You can see illustrations of the connectors in the above link - I really advice you to read it, since it thoroughly explains everything you may need to know. I also remember seeing a quick and dirty rundown of the differences on the nVidia site, you will find it if you search for it. The above link is far more exhaustive, though.

Going to abandoned the Big Box forever. Need to be very portable in the next year or two. Two questions to begin: 1. Many laptops seem to only be able to turn off Secure Boot through the OS, Windows 8.x, or so I've researched. However, I've read some makes (Asus, Lenovo, Dell and HP) can do it directly through BIOS without needing to boot Windows? True? Any others? I don't have a laptop myself (don't like them), but every one I've seen so far has had a switch to disable Secure Boot in the BIOS. AFAIK, that switch is mandatory to adhere to the Built For Windows 8 MS program, although it is only optional for the coming Windows 10 program. That might be something to watch out for. I've read about that, but right now until W10 in its final form is release, nobody really knows for sure. Well, yes and no. We *do* know that the status has changed from mandatory to optional, but whether hardware manufacturers will actually remove the ability to turn Secure Boot off remains to be seen. If this is going to become a real problem or not, we will just have to wait and see. 2. How UEFI compatible is Debian Wheezy? What I'm running on the Desktop. Or is Jessie the better choice. Or something else entirely? Except Ubuntu variants (Hate it!). I don't want to run in Legacy mode for future compatibility. I won't be installing a desktop, just a window manager. Probably Openbox. You can find details here: https://www.debian.org/releases/stable/amd64/ch03s06.html.en#UEFI Yes, I read that during my initial research. I believe the Canonical people have put some effort into becoming fully Secure Boot-compliant, but if you do not like them, then that is not an option. There are also others (RedHat?) but I can't remember who. That compatibility comes from the Linux manufacturer buying a Microsoft Secure Boot key which Canonical and RH have. SUSE, too, I think. Don't know how much that costs them. I prefer not to have Linux under Microsoft's thumb that way. I absolutely agree. I have no problems with turning Secure Boot off and leaving it off. It's just that I fear that in the future one won't be able to turn it off. And that will really throw a wrench in the Linux community. We'll see. The Linux Foundation is also examining the possibility of obtaining a key that can be used to sign images for distributions (free of charge), and there is also work being done on signing a shim that will launch a real bootloader.

Yes. I read that. Wonder what Microsoft has up its sleeve? If I were to guess, this is in preparation for at some point in the future requiring Secure Boot to be used, without the ability to turn it off. You know, think of the children!. Maybe, this is indicative of W10 being even more insecure than previous Windows' OSes. Secure Boot itself is not actually such a bad idea, in some circumstances it might be nice to have a fully signed chain. IMHO. In itself, it should help to make Windows *more* secure, but this is hardly the right place for that particular discussion. Nor do I care :) I have no problems with turning Secure Boot off and leaving it off. It's just that I fear that in the future one won't be able to turn it off.

Although, instead of a patch or shim, the threat of a class action lawsuit by Linux developers might be more effective. Hardware manufacturers will have to take into account the fact that there are a large number of people and organizations that run their machines without Windows, so I don't think there will be a lack of machines that can turn Secure Boot off in the near future. But will it become something to watch out for when buying new hardware? Most certainly, at least for a period of time. I have a sneaking suspicion that it might become a bigger problem for laptop users than for desktop users, although I'm unable to back that up. For those of us who prefer to build their own machines, I think it will be much less of a problem. The cleanest option would probably be to allow the owner of the machine to install his/her own keys in the firmware, and sign the boot image with those. And we still have legacy mode. For now. In my view, a solution for Linux that doesn't work for our BSD brethren and other people would not be good enough - we shouldn't settle for it. I remember all too well how hard it was to get Linux (or BSD, for that matter) up and running with new hardware back in the day, and I don't want a return to that state of things. There may very well be another Linus quietly tinkering away at something that might become the Next Big Thing out there, and it would be a shame if we were to limit hardware to not make that possible. I am also not sure MS really _wants_ to lock Linux/others out of the playing field. If they do, I assume the murmurs of class-action and anti-competition would rise in pitch, and someone might do something that could *really* hurt them. They really should work with the community to come up with a solution that works for everyone before someone forces them to. Petter -- I'm ionized Are you sure?

Apparently these are more or less hard-wired to work with Windows 8. Argh. Why the fsck can't these people just build hardware that works the way it's supposed to?

Thanks a lot for the link, I didn't notice the RH link when I did my searches. I also learned something new about udev today :) In the long run, it's probably easier to have it replaced... It would also be the correct thing to do, to not encourage them further to make broken hardware, but as I mentioned it would be a big hassle. The mouse itself is also quite nice.

They used I don't have money to send to Red Hat. First of all, one reason (although not the only one, by far) I am using Linux is it is free of commercial restraints. Secondly, these are not commercial systems. These are a pair of home RAID arrays used primarily to store a personal video library. Thirdly, I rather dislike Red Hat's distribution and administration system. I much prefer Debian. I am sorry if this is a dumb question, but if this is a home system, why can you not go for more commodity hardware? While I do recognize there are differences between SAS and SATA, do you really need SAS in a home setting - for a media library? SATA may be the simplest/cheapest solution, to my way of thinking. I would assume there are far more people running Linux with a SATA system than there are for SAS, so it should be more widely tested, and information would not be so scarce. Granted, this might be less true when you are talking about high-end RAID controllers, but still. (Note: I know next to nothing about SAS and expensive RAID controllers, so I may be way off-base here) Just as an aside, this is a Debian user forum. Frankly, it strikes me as a bit strange to advise someone asking a question concerning an ordinary use of Debian to go somewhere else. Here I agree with you. OTOH, if this had been for a enterprise setting, a suggestion to check out RH - with their level of commercial support - would not necessarily be a bad one. Canonical might have been another one, I haven't personally dealt with them. to be very good at reliably supporting a lot of different hardware. (I'm out of that consulting biz now...for some time now.) Honestly, IMO this isn't primarily an issue of hardware support. It is an issue of informational support by the hardware manufacturers. They post lots of fru-fru information about their product without posting the information one really needs to know to make an informed purchase. Very few of the HBA manufactureer inform the user whether the card at hand supports LBA 48 or not. I have purchase several controllers only to find the drive size limited to 2T. Many devices that only specify RH and / or SuSE are in fact perfectly well supported under Debian and most of its derivatives. Many just report Linux support, when in fact there is no support under many distros. Again, I agree. In this scenario, I would find a couple of controllers that would seem to suit my purpose, and contact the manufacturers directly with very specific questions. One of these questions would be whether or not the controller is supported by the Linux kernel itself, or if it would require third-party software/modules to work, and if so, what systems those are available for. Since there are so many distributions that are based on Debian, and especially Canonical seems to have a little clout with manufacturers, I would suggest to them to investigate support for Debian-based systems. Not supporting it in this day and age would seem strange to me. There are many fates worse than becoming, for certain of one's key systems, a RH customer. Even more so if making money, or deliverables, is part of the job of said key systems. It is not, and economy is definitely a key consideration, here. What's more, I am not asking the OS to support any particular hardware. What I am asking - even if it were REd Hat - is whihc hardware is supported. That really should not be that difficult a question. (Yes, I understand why it is in fact a difficult question.) Yes, it is indeed a difficult question. This is just personal preference, but I would as far as possible avoid hardware that isn't supported by the Linux kernel itself, since that would leave me at the mercy of the manufacturer with regard to future support and updates. It boils down to the question How much of my time do I want to waste looking for those hens' teeth, and, These aren't hen's teeth. They are type O-Positive blood donors. I just need the bag labeled with the blood type so I know which one to choose. given what my time is worth, do I want to take that hit? As opposed to the huge amount of time it would take me to switch operating systems? Few, if any, of the dozens of scripts I have in place to manage the system would work out of the box. They would need to be re-written. Nearly all of the software I have written would have to be re-compiled, and some might need to be re-written. I would also have to spend a lot of time getting far more familiar with Red Hat than I am now. No, by far the most economical route is just to buy HBAs

Yes. Exactly. Also 'stunnel4' is useful too. Thanks, I didn't know about that one. I would avoid IPsec. Last I looked there were more than 55 RFCs that had some impact on IPsec. It has traditionally been rather of a messy thing. Urgh, that sounds painful. I think I will steer clear of that, then. That would also explain why there is so little info on it on both the Debian and the Arch wikis. The problem is that I haven't really messed with any of these before - what would be the best choice in this situation? Note that I'm not asking for a complete configuration, all I want is some advice as to which of these technologies I should begin to read up on. The IPsec article on the Debian wiki is from Sarge, so it is quite outdated, but the openvpn article is recent and seems helpful. Any insights/advice/links, etc? Using ssh tunnels will get you 80% with 20% of the work. Using OpenVPN will get you 100% with 100% of the work. Using 'autossh' to manage ssh tunnels is very reliable to run and very quick and easy to set up. I use all of autossh/ssh tunnels, stunnel4, openvpn in different places. I tend to like and use the autossh/ssh tunnels because they are quick and easy and work well enough that I can move along to something else without spending a lifetime managing them. It doesn't require any routing table modifications. Not requiring explicit routing is a bonus, but not really a dealbreaker for me. Besides, I am sure the Debian wiki will give me enough hints to get it right. I like stunnel4 for some things because it also is very easy to set up and very reliable. Either ssh or stunnel would seem to be good simple effective choices for remote sysloging. I might lean toward stunnel for this. It all depends. Using stunnel benefits if you have signed https ssl certificates already that can be verified by stunnel. I don't already have certificates, so I would need to generate some. As I already have a little experience with ssh and keys, it would probably be a wiser choice. Both ssh and stunnel use TCP which means that in terms of ultimate performance and ultimate efficiency you are ending up with TCP over TCP and that isn't perfect. TCP over TCP will use some resources and time transporting packets somewhat inefficiently. I think for your example of using remote syslog logging I wouldn't worry about it. It is a non-interactive task and the machines won't care when talking to each other. No one will ever notice the inefficiency. When operating interactively such as working from my laptop to my remote servers I am usually interactive. That is when transport artifacts of latency become noticeable and annoying. There I have put in the extra work to set up openvpn for the 100% solution. It uses UDP for the transport avoiding the TCP over TCP issues. It is more work to set up initially due to dealing with setting up ssl certificates and routing. But having set it up it is a high performance solution that does 100% of the job. I would probably start your remote syslog task using autossh/ssh and then worry about doing something more when the need for more arises and not before. Thank you for your insight, that was very informative. From what I gather from this, it might be just as well to go straight to openvpn. Let me explain. Already I need rsyslog, munin, and collectd. That would require three separate ssh/ssl tunnels. However, if I set up openvpn on the router I will just need the one tunnel, and I can set up remote access to my home network at the same time, with the same bits and pieces. Actually, I won't even need to set up anything special to reach my home network, as I would be able to reach it from the VPS - which already has ssh open. The need to reach my home network is already here, as I don't really have a good way of doing it currently. One thing I forgot to ask, though: how intensive is openvpn on resources, especially CPU and memory? I was initially thinking of setting it up on the router, but I am a little worried that it might be too much for it to handle. Would it be feasible/better to set it up on a more powerful machine on the inside and forward the traffic? And again - thanks, Bob. Petter -- I'm ionized Are you sure?

Basic shell substitution. The task there is to include (foo) in the

will use $debian_chroot and if it is empty then it will be empty and
if it is set to foo then it will expand to foo. Almost works. That
would expand to foo not (foo) with the parens around it.

The ${parameter:+word} construct is used a lot of shell programming.
Editorial remark: I really wish the author of /etc/debian_chroot had
simply made that /etc/chroot_name or some such. Because by naming it
/etc/debian_chroot guarantees that no other distribution will pick
that convention up and use it. If it had been /etc/chroot_name or
something non-distribution specific then it would have been possible
to share across other distributions. Sigh.

I have it much less since I have decided to only use intel chipsets or processors with integrated GPU, bit still sometimes. If I could, I would definitely buy a _discrete_ Intel video card, but that's not happening. Buying a new processor with integrated GPU is also not happening, since that would involve switching motherboard, probably memory sticks, and maybe other things. It would end up to be expensive. I notice that neither of the answers address the real issue, although your previous paragraph (the one I snipped) does for a particular model: support by Linux KMS and X.org, hopefully with Free drivers. Yup, this can be hard to figure out. The reviews of video cards online almost always use the proprietary drivers, and I'd like to avoid that if I can. After all, today's budget cards were high-end three years ago. For a non-gamer, 3D was more than adequate ten years ago (armagetron ran at the monotor's refresh rate thirteen years ago with a middle-class card) and accelerated video rendering (not decoding) was tearless. Hardware video decoding is more recent, and even nowadays the lowest end chipsets (Atom and the like) do not support it in any useful way. Support for the high-end pixel formats (yuv444p10) is even more recent. Yes, this is why I suspect that I might want a fairly recent card, but it's hard to find one that supports the things that I may need without having to pay for a lightning-fast GPU and a metric ton of memory. There are some pages on the X.org wiki: http://www.x.org/wiki/RadeonFeature/ But they are not always very easy to browse: the dates and minimum versions are not written, nor the market lifetime of the cards. So you may be looking at a very interesting all-green controller until you realize that you will either have to pull X.org from Debian experimental or that it has been out of sale for two years. The mapping between the technical names used on the X.org wiki, the PCI Ids (and translated names) and the commercial names is annoyingly hard to find too.

I don't believe so. The VG is the mapping layer in the LVM stack. It maps the LVs to the PVs. If you were to share a PV between VGs, then you'd need some way to tell the VGs which parts of the PV they can use (letting them battle it out and potentially over-commit the PV is not really a good idea). The easiest idea is to split the underlying device into multiple PVs (e.g. use partitions). I see, thank you for the explanation. If so, how can I make a VG with lots of free space smaller? I'm suspecting that the answer to my first question is no, since this doesn't seem possible from the man pages. A quick bit of searching suggests the incantation would be: * Boot from a rescue/live disc * Activate your VG * (You say you've got unallocated space in your VG, so resizing filesystems/LVs won't be covered) * lvm pvs should, at this point, indicate some PFree, which is how much you can shrink the PV * Run lvm pvresize /dev/whatever --setphysicalvolumesize 50G (Where /dev/whatever is the PV device and 50G is the new size to resize to) * Finally, resize the PV's partition appropriately. At this point, you will have a smaller PV and less unallocated space in your VG. You can now create another partition, PV that and add it to a second VG. I figured I would have to do that. It's not really a problem right now, I was mostly wondering if it was possible without messing with partitioning.

I forget. Since doing that, I realized that for many years I have been running with my own version of /etc/ssh/ssh.config. Confronted with the evidence, I recall that this was a place I found, through exhaustive search, to turn off the hashing of known_host. I like to be able to identify lines in known_host, because I think each line is a possible access path for a hacker and the sysadmin, namely me, should be able to trace the provenance of all such lines. In short hashing them opens a backdoor more serious than the one it closes, IMHO. I now know that I can put my edits in two places, /home/pec/.ssh/ssh_config and /root/.ssh/ssh_config, and have the same effect. If you're happy with not hashing, you need only put that in /etc/ssh/ssh_config (underscore, not dot) if you remove all other .ssh/ssh_config files. I can envision a different way, but I cannot envision one that does not impact of how Debian wants to configure Jessie. So be it. When upgrade runs, you'll need to keep your configuration and then run diff against the maintainer's version (suffixed .dpkg-new or .ucf-dist or some such) to fold in any changes they've made (likely to be few to none). I have not yet discovered a way to append new known host keys from newly configured hosts into the .ssh/known_hosts files on older computers. known_hosts and authorized_keys are both text files. Each line is independent. You can cat x y to append contents of x to y or insert with an editor. An editor's Insert File is safe, but make sure to reconstruct the lines if cut and paste does any line wrapping, ie ssh-rsa jhdgkhkkdjkjnskjn foo@bar needs to be made back into ssh-rsa jhdgkhkkdjkjnskjn foo@bar IIRC any line from one hosts's or user's known_hosts file will work for another user and/or host, and the same with authorized_keys (though don't mix them up!). I think the removed file was the one associated with either pec, or root, which ever was appropriate for a test. Since doing the tests, I have done a complete re-install. With that removing the appropriate known_hosts file gives me the old familiar option of accepting the risk of man-in-the-middle. There's never a problem with wiping out known_hosts and letting it gradually be rebuilt, particularly if you know the fingerprints thusly: $ ssh-keygen -l -v -f /etc/ssh/ssh_host_ecdsa_key.pub .../ssh-fingerprint As said before, I am working now with a new re-install on my main computer.

The rest were provided by me, after I took the CD out of the computer and rebooted. Well I have tried to keep things as simple as possible and I recently decided to call exim's bluff...

It kept breaking so I found alternative for a previous stand-alone smtp agent that was being discontinued due to lack of upstream support at about the same time that Debian was moving from plain exim to exim4. I could try again, but after I get ssh working both directions, I hope. Starting MTA:hostname --fqdn did not return a fully qualified name, dc_minimaldns will not work. Please fix your /etc/hosts setup. exim4 ok ...and configure a null domain (ie no dots in /etc/hosts outside of the IP numbers). Everything still works. With this, I can ssh into 'gq' from 'big', which is my main computer with the big flat screen display. I can open and edit files on 'gq' and the edits will be saved. No problem. But, if I sit down the keyboard and screen connected to 'gq', I cannot do the reverse. On 'gq', the /etc/hosts file contains all the lines as on 'big', except for the first two. It should contain the first two lines exactly the same except substitute big→gq. Working on 'gq', I cannot ping ['big']. Can you tell be why, and what I can do to make the ping possible.

Another dumb thing is that the DDOS protection is only running on the _internal_ interface. As I don't need anyone to keep me from ICMP-flooding anyone else, that seems like a really stupid decision. When flashing, change the password, and the admin account name if you can, but in either event, paint it on it so you can always get back into it if its in your home secure. And use 18+ char passwords, make the blackhats work their butts raw to get into it. Don't worry, I have locked it down as hard as I can, even though it makes it a pain to connect new devices.

You probably also want fglrx-amdcccle_14.501-0ubuntu1_amd64_UB_14.01.deb, which is the graphical setup utility. There is also a development package for OpenGL, which you may or may not want. Thank you for that. It is unfortunate that the AMD web page that linked to the download for the package that depended on that package, di not include a link to the package, with some information like the package needs this package to be installed, which can be downloaded form... The page mentioned above lists all the available packages for Ubuntu, although it does not say what the package dependencies are. I'm guessing that would be available in the install instructions. But. These packages are for *Ubuntu*. Ubuntu is not Debian. Yes, they both use .deb packages, but that does not mean that the Ubuntu packages will work well (or at all) on Debian. Personally, I have no idea, as I haven't tried, but I would take a backup first, as they may hose things considerably. I am well aware that Ubuntu is not Debian, although, from what I understand, it may still be derived from, and, based on Debian. I am sure you do understand that, it was more meant as a form of warning. These packages are intended for specific Ubuntu versions, if you try to install them on a Debian system, you may not have the same version of the kernel, the X server, and various other components that are relevant to how the driver works. In other words, they can damage your system. Based on Debian does not mean that important system packages are interchangeable. If I'm not mistaken, Ubuntu get their packages from Jessie/Sid, if you try to install on Wheezy you likely have an older X server, at the least. I wouldn't attempt it without first doing a little research. As I had said, the Seamonkey package for Ubuntu, installed and runs okay on Debian 7, and is the only source that I found, of a .deb package for Seamonkey, so as to allow Seamonkey to be installed using a Debian package manager, such as (I think it is) gdebi. That may well be the case, and I expect many packages would work fine on both Debian and Ubuntu systems, but the driver for your GPU is a system package that expects certain things in the environment it is installed into. You *may* have better luck with downloading the .zip file for Linux and using the installer to build a .deb package for your environment - it has an option for doing this. That's why I suggested you look at the Debian wiki, for example, as I am sure you will find more information on the best and most reliable way of doing this. You don't want to hose your X setup. I just did a quick search, but found nothing about installing the 14.12 version of the driver on Wheezy, everything I can find references older versions. Assuming that the 14.12 driver is compatible with the X server in Wheezy, which may not be the case, most people seem to go with the route of creating packages from the installer. YMMV. The fglrx driver that Wheezy has is older, much older, so your GPU is probably not supported. If the 14.12 version requires a newer X server, then this whole exercise is going to get quite involved.

Then you also have the ability to take a snapshot of /home for when you run your backups, as to make sure you get a consistent image?

Petter You really should send your reply to the list, not to me personally, so that more people can see it, and potentially help you. I agree and this reply is to the list. I only replied directly to you because last week I received a sharp rebuke from an individual who had responded to one of my posts. He claimed it is very bad manners to post his responce - it was a very helpful one which I acknowledged - to the list when he had responded from his personal address. I didn't mean to sound harsh, and I apologize if I did, I was in a hurry, and just wanted to forward your message to the list so that more people could see the message and potentially help you. Strictly speaking, I shouldn't have done that, as it's considered quite impolite to forward personal mail to a list, but since you didn't actually say much except including the log files, I concluded that no harm would be done. What is the protocol? In reponding should I hit r or L? Obviously a continuing string of discussion posted to the list should be advantageous to all. When you are responding to something in a list thread, send your reply to the list. That's considered the right thing. It is generally frowned upon to reply in private, although there are occasions where it is appropriate to do so. In this case, you should probably have sent your reply to the list instead of to me, partly because you want as many people as possible to get a look at the logs to see if there is anything wrong there. Also, if you discuss something with someone off-list, you should always get their consent to forward something they wrote to a list. I didn't do that with your message, and for that I apologize. Does that explain things to you? Now, to your original question: I must admit I haven't had the time to take a good look at your logs, although nothing jumped out at me. I will take a closer look at them, hopefully someone else with more experience can also do so. Petter -- I'm ionized Are you sure?

As I've noted on another recent thread, some cloud providers (Yandex, Box) offer WebDAV access, which (potentially) makes linux access relatively straightforward via something like davfs2.

But, in my defence, I think I used tar once or twice in the second millennium, but never knowingly since. Normally I would have had cpio on the end of that pipe, not tar. You have nothing to defend, I was just making a joke on what man page would be the easiest to find what I needed in. A tarball was good for what I needed to do, and it's what I was most familiar with. But, to make a serious point, knowing how to use find is a valuable skill as plenty of software doesn't have the options that tar now has. Absolutely, and I use find frequently, it's a valuable tool.

Something like: Exit codes and their value in real life. Strings handling, memory allocation. Process control and daemonisation (sp?). Signal handling. Inter-process communication (sockets, pipes).

With extra focus on 9 and 6b :) Also things like communication between processes and devices, file systems, etc. I want to learn how to find out why things work the way they do, if that makes sense. If you want to understand the basics, there is any number of tutorials on the web. If you want to play with them, then pick a language and go to a web page like https://docs.python.org/3/library/index.html and write some toy programs. Most of these facilities have wrappers that save you having to write C code to create, say, a couple of sockets that talk to each other. If you try this in C and it doesn't work, it might take you half a day to decide whether you've misunderstood the socket concept or just made a programming error. I can understand that. As Reco said, [...], and for the complex program you'll probably want something else as by today's standards C has poor result/effort ratio. That I can also accept. I see that a lot of people advice me on going with something other than C, and I can understand that there are good reasons for this advice. While I still want to learn C at some point, I'm beginning to think that it might be wise to consider getting a good foundation in another language first. Would Python be appropriate? I see a lot of software these days that is written in Python, so it would be helpful in that way. The person I am most likely to go to for help knows Python, so that's a bonus. And on the subject of books, what would be a good introduction? Petter -- I'm ionized Are you sure? I'm positive. pgpmglATf2JKJ.pgp Description: OpenPGP digital signature
