Re: [SLUG] patch your bash shells now
Menno I believe that is the old test, not entirely accurate.
This one is supposed to be more accurate.
rm -f echo; env X='() { (a)=\' bash -c echo date; cat echo
If you're safe it should return:
date
cat: echo: No such file or directory
I'm no BASH expert so I'm not too sure how the two tests differ in terms of
effectively detecting the vulnerability.

bash: warning: x: ignoring function definition attempt

Hey SLUG,
I'm sure everyone's aware of this issue.

If your running debian, they re-released a patch this morning (a
complete
fix now).
If you think you are not affected, YOU ARE AFFECTED, patch all your
systems (this has so many vectors).

Re: [SLUG] Help to force install in CentOs (TOR in China)
Hi Robert, I'm not really familiar with installing Tor. What distro are you using? And whats the problem you having installing Tor? Is it that the package cant be downloaded from the pre-configured repository sources because the Great Wall is blocking the download? or that permissions on the VPS wont allow you to install the package?

Re: [SLUG] BASH update for Debian 6?
thanks for the tip Mark, I had considered trying to install the BASH update for Wheezy on my Squeeze machines but the thought of getting the dependencies met seemed daunting. I tried your commands but as suspected, ran into dependency issues - Multiarch-support needs libc6 = 2.13-5, updating libc6 requires a newer locales, and on it goes. The default shell on my systems is /bin/dash and /etc/passwd shows all accounts except mine and root have /bin/sh (dash) as their shell. So it might just be easier to change the shell for my account and roots account, and then uninstall BASH.

Well I dont want to tunnel all streaming traffic accross it and Netflix doesnt require all connections to be from the U.S. Only when you browse the Netflix catalog and when you chose a show/movie to watch does the service check location, after that the web browser, Apple TV, other media device is redirected to a CDN to stream the content. and that CDN doesnt care where I am from. So I get better throughput by not tunnelling the video stream. Now a hosts file would fix this problem very nicely.but Apple TV doesnt have a hosts that is accessible and thats where I do most my streaming from. Interestingly, I can watch Hulu on my PC with my current setup with zero problems. Its when I try on the Apple TV that it talks to a248.e.akamai.net and throws an error that I'm outside the U.S. I believe dnsmasq lets you change host addresses of single hosts in a large domain with a 1 line entry, not a bind solution, but it's really easy to do with dnsmasq, i have no idea how to do it with bind. dnsmasq has this functionality for things like blocking ads, but you can use it for any purpose # Add domains which you want to force to an IP address here. # The example below send any host in double-click.net to a local # web-server. #address=/double-click.net/127.0.0.1 # --address (and --server) work with IPv6 addresses too. #address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83 # Add the IPs of all queries to yahoo.com, google.com, and their # subdomains to the vpn and search ipsets: #ipset=/yahoo.com/google.com/vpn,search -- 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

[SLUG] BIND9 zone question
Hey people, Got a bit of a tricky question, well it seems tricky to me. I want to use bind to resolve a single host address for a very large zone I don't own. The background is that I'm trying to circumvent georestrictions on TV streaming site. I've determined that the host on the internet that has an issue with my location is a248.e.akamai.net Now, I don't want to hijack the whole akamai.net domain on my internal DNS because I would be forever adding new DNS records. I tried creating a new master zone named a248.e.akamai.net and setting an A record for the root but it seemed the DNS server was ignoring it and forwarding the request to upstream resolvers, resulting in the real IP being returned...which is not what I want, I want it to return my chosen IP address.

Re: [SLUG] BIND9 zone question
Hi Christopher, You're right that this Akamai hostdoesnt like my location, and you're right that Bind and DNS *alone* arent going to resolve that. But the bigger part of my fix that I havent revealed is that I change the ip address of hosts to point to loop-back addresses on a server in the US, which then does a TCP redirect to the original host, and this lets me bypass georestrictions quite nicely. For example: My computer requests secure.netflix.com My internal DNS says that host is at 192.168.1.20 My computer opens a TCP connection (port 80 or 443) to 192.168.1.20 The daemon listening on 192.168.1.20 on my server in the U.S then redirects/rewrites the connection to the hoist secure.netflix.com Theres no proxying involved because the requests are often over SSL and so my machine in the middle breaks the SSL security.

Re: [SLUG] BIND9 zone question
Correct, The Netflix servers are seeing my requests come from my server in the US. Thats the whole point of having the server in the U.S. And it works very well for getting access to Netflix. Netflix and Hulu both use Akamai, although Netflix appears to use other CDNs as well. The difference is that the software Netflix uses to serve up the video stream doesnt check location, it only checks that the viewer holds a valid license to view the stream, whereas Huhu's service seems check my location at every request. Proxy vs port forwarding does make a difference. for proxying to work the proxy would need to inspect the request. But since the request is encrypted the proxy would need to decrypt, inspect, and then re-encrypt, which causes a Man-In-The-Middle. While PCs dont care about this in so far as the user can chose to ignore certificate warnings, other devices like Apple TV, the Netflix app on Android, etc wont let you ignore bad certificates. So proxying wont work. TCP redirect where theres no need to inspect the inner data stream is the only option. The point of fiddling the DNS is that I can redirect requests for various Netflix and Hulu hosts to my own server in the US and have my server in the US redirect the request to the correct Netflix or Hulu host. so for example: www.netflix.com points to 192.168.1.10 secure.netflix.com points to 192.168.1.20 movies.netflix.com points to 192.168.1.21 etc On Thu, Aug 14, 2014 at 10:05 AM, Christopher Vance cjsva...@gmail.com wrote: So you have your own server in the US.

Re: [SLUG] BIND9 zone question
Ok turns out the problem was just a typo I had overlooked NUMEROUS times. I
had been watching /var/log/bind.log which hadnt reported any problems. It
wasnt until I took at look at /var/log/syslog that I saw the problem.
localhost named[19832]: zone a248.e.akamai.net/IN: loading from master
file /var/lib/bin/a248.e.akamai.net.hosts failed: file not found
zone a248.e.akamai.net {
type master;
file */var/lib/bin/*a248.e.akamai.net.hosts;
};
the path should of course be */var/lib/bind* not /var/lib/bin
so I can now resolve a248.3.akamai.net to my local server and all other dns
requests for the akamai.net domain are sent to the forwarder to resolve.

Wow thanks for that Glen. Stacks of useful info. Given me a bit more to think about. I wasnt intending to run the PIs too far apart. At the moment i have them in cases but i was hoping to throw them into an enclosure like a blade system (minus the hot-swapability) or like the Pi clusters you see where they are mounted close together, and I was hoping to daisy chain the gpio headers but if additional logic components are going to be needed then my approach might not work so well. might do some looking into REST over CoAP and see where that takes me.

I2C slave support depends on the particular I2C driver. It isn't very common and won't be in a mainstream kernel. As for the master/slave issue, that's easily solved if designed in from the start as I2C is a multi master system so you give those particular nodes both master and slave functions. Of course the RPi has only one I2C port. There's not much call for IP over I2C as the I2C bus has a maximum capacitance of 400pF. That's a couple of metres. Also, the value of the pull-up resistors will vary with the capacitance (ie, cable length), and in this high capacitance environment you'll want to use an active I2C terminator. This is all easy enough to arrange on a PCB, but gets problematic when using cabling and you're starting to talk daughterboards to hold all of this additional logic, not just connecting one RPi to another. What you'll often find on PCBs is I2C used for simple devices and a USB hub used for complex devices. For example the RPi itself uses USB to attach its ethernet port. USB brings device enumeration, peer operation at the protocol level, device profiles and so on. The RPi is a mobile phone CPU. So its I2C is really focussed at firmware downloads to the radio devices, a simple power-on self test (enumerate that the devices which should be reachable are in fact reachable), and commanding FPGAs and devices (such as bringing the transmit amplifier online) - IPv4 works fine on broadcast-less media, that was it's original use. In this case you'd hardcode the I2C link layer address and it's corresponding IPv4 address. In the GPIO case you don't care about the address at the other end of a point-to-point link, stuff which is addressed for your subnet but which is not the null address or your address needs to be transmitted. In the USB case there's an adaption protocol (CDC or RNDIS). IPv6 is simpler, you'd just include the i2c address in the lower bits of the IPv6 address. What you usually do isn't to run IP cover I2C, but to run IP to lightweight controller software, which then bangs the I2C bus. There's a special web-like protocol: REST over CoAP over IPv6 which is focussed on being easily proxied from a full REST/HTTP/TCP/IP. -- Kind Regards, Christopher Barnes e. chris.p.bar...@gmail.com -- 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] TCP/IP over I2C
yeah. come to think of it. the whole master/slave process of I2C would probably make it terribly difficult to implement tcp/ip since each device would have to be able to switch from slave to master to be able to send broadcasts like arp requests, netbios name requests, etc. Otherwise the slaves can only send data in response to a request from the master. oh well, never mind.

Re: [SLUG] On switching ISPs.
For a moment I thought I'd been subscribed to an Android support mailing list My guess as to what you are asking is do you need to save the phone contacts from your old sim card before turfing it? Please correct me if I'm wrong. Its a bit hard to say but generally Android likes to chuck all your contacts up to the cloud meaning they should already be on the phone when the new sim card is installed. You can probably check this by launching Gmail in the web browser on your computer and check your Contacts. If you see the contacts that were on your sim card in your Gmail contacts list then you shouldn't need to copy them from the old sim card. Hope that helps and sorry I cant be more specific.

Re: [SLUG] hosts bind order?
I am no expert - but I _think_ that the configuration files and the behaviour of commands like ping and host do make sense. In particular, ping is checking /etc/hosts, but host is specifically intended as a DNS checker, so has no reason to consult /etc/hosts. But your main problem lies with Postfix, and that is a whole different can of worms. The command 'postconf -d' reveals several configuration items relating to 'resolve' and 'dns'. Furthermore I found this link: http://www.linuxquestions.org/questions/linux-software-2/force-postfix-to-refer-etc-hosts-857662/ which I think describes your problem - and supplies an answer.

Re: [SLUG] ISP Recommendation
depends how much you'd like to spend, how do you feel about needing static ip addresses, ipv6 support, etc. but basically, take a look at the Whirlpool Broadband Choice website. You can punch in your phone number and it will present you with a list of available internet providers and their plans. You can filter the results so you can exclude bundle plans, cap the monthly spend, specify your minimum download quota, etc http://bc.whirlpool.net.au/ i currently use Internode, im on a 200gig plan (no offpeak or onpeak) with land-line phone included. They do dual-stack ipv4 and ipv6 on their ADSL2+ service which is good if you want to start using ipv6. and you can also apple for a static ipv4 address which comes with a complementary sub-domain (WhatEverYouLike.power.on.net) to point to your static ip. Service is good, never had a problem. Only been with them a year though. Before that I was with iiNet. Really Good. Very fast. I had a similar plan to the internode plan except with onpeak and offpeak quotas, but iiNet dont do static ips for residential plans, or ipv6 (last i checked).

Both parent and child resume/start executing at the next instruction, which

the
parent gets a non-zero positive value. So in the parent, pid 0 whereas

Re: [SLUG] newbie to writing programs
Yeah I've read the man page and web sites looking for an answer.
The what i dont understand is that if the child is an exact copy of the
parent, why doesnt the child spawn a child and exit?
The only explanation i can think of is that when fork() is called the
forked process starts from the position in the program where the parent was
when it forked.
What i mean is if the parent forked at the line
pid = fork();
Then the child would begin executing at the next instruction. In this case
If(pid 0){ exit(EXIT_SUCCESS); }
Rather than the child begining begining execution at
int main(void){
And since the child process wont have a value for pid it wont exit, but the
parent will.
Does that make sense?
Chris Barnes wrote:
I can daemonise processes, the problem I've got is I cannot for the life of
me understand HOW it works.
Have you read the man page for fork? On my Mac (BSD unix) it says:
Fork() causes creation of a new process. The new process (child process)
is an exact copy of the calling process (parent process) except for the
following: ...
and so on.
from what I understand about fork() is that it copies the parent process to
a new memory location, and gives it a new PID.
correct
But based on this example it reads to me like the child AND parent should
terminate after forking another copy of themselves, over and over.
nope.
The parent receives a non-zero pid of the child as the return value from
fork()
and continues executing as the original process. The child process receives
a zero as the return value and continues executing as the child process.
There
are now two independent processes running, except that they are sharing a
few
things like open file handles. That is why the child process closes the std
I/O
files.
I've tried this code and it works perfectly so I'm not seeing an endless
loop of forking and terminating processes.
Where is this endless loop of which you speak? In the example you give,
the parent process exits after the fork. So it is gone. Dead. Terminated.
The child goes on and daemonises itself. And then enters its unspecified
work loop.
/* Fork off the parent process */
pid = fork();
if (pid 0) {
exit(EXIT_FAILURE);
}
If fork() returns -1 then the call failed, no child process was
created. I don't think a test for 0 is correct, BTW.
/* If we got a good PID, then
we can exit the parent process. */
if (pid 0) {
exit(EXIT_SUCCESS);
}
In the above code segment, the parent exits. We know we are in the
parent process if pid is not zero. Thus, the parent exits.
Now, the code below is only executed by the child process.
Read the man page for setsid() for more info about creating a
new independent process group.
fork() is a powerful tool for multi-processing. The example you gave
is the Unix wizardry used to turn a process into a stand-alone
daemon in its own process group. There might be other ways to accomplish
this, but I leave that to the wizards.
Another comon use of fork() is to create child processes to do some
work in parallel to the parent process, perhaps on other CPU cores,
and then wait for the kids to finish, and co-ordinate the results.
cheers and I HTH!

[SLUG] PyCon Australia 2012 Conference Programme Revealed!
(Hobart Tasmania, 15 June 2012) With both of our keynotes announced, PyCon Australia is very proud to be able to reveal the programme for the 2012 conference, to be held on Saturday 18 and Sunday 19 August 2012 in Hobart, Tasmania. Following an impressive response to our Call for Proposals the conference will feature three full tracks of presentations and tutorials, across two days, covering all aspects of the Python ecosystem, presented by experts and core developers of key Python technology. Our keynote presenters, Mark Ramm, Engineering Manager on Juju at Canonical [1], and Kenneth Reitz, Python lead at Heroku [2] will be joined by a wide array of presenters covering a broad range of backgrounds, including industry, research, government and academia. As ever, PyCon Australia is a great place to keep up-to-date with the latest trends in Python web technology: From Heroku, Lincoln Stoll will be presenting on the 12 Factor Method for building software-as-a-service apps [3]. Other web related topics include deployment and testing techniques for Django applications and techniques for asynchronous web programming. There's also a wide range of talks for the rapidly growing community of developers using Python in science. Edward Schofield's survey of the latest developments in Python for Science and Engineering [4] will get you up to scratch on what tools and techniques are shaping the Python world for scientists. From there, case studies and introductory talks will delve into all aspects of Python in science: including techniques for handling large scientific data sets, natural language processing, and data visualisation -- attendees working with Python in all fields of science will gain something from PyCon Australia 2012. Finally, for newcomers to Python looking to quickly enhance their Python skillset, Graeme Cross' tutorials [5] in our Classroom stream will help you to rapidly enhance your knowledge of Python -- you can then attend our general stream talks to glean a snapshot of the state of the art in Python. PyCon Australia 2012 programme committee chair, Richard Jones, was impressed with the level of response to the Call for Proposals, which closed in early May: We had an unprecedented response to our Call for Proposals this year, and this has helped us to put together one of the strongest programmes ever at PyCon Australia. There's something for every developer working with Python in this year's programme -- be they working in web technology, in research, or even if they're just a Python enthusiast who wants to learn more about their favourite language. The full schedule for PyCon Australia 2012 can be found at http://2012.pycon-au.org/programme/schedule Registrations for PyCon Australia 2012 are now open, with prices starting at AU$44 for students, and tickets for the general public starting at AU$198. All prices include GST, and more information can be found at http://2012.pycon-au.org/register/prices We're looking forward to seeing this excellent programme brought to life at PyCon Australia 2012, in Hobart, in August.

I cant say I have a lot of experience with the dedicated scanners but from what I've seen the expensive ones are very fast and very reliable. They also come with a scsi interface option. i worked at a mortgage lender years back and one of the departments had these expensive scanners because they would scan piles of 20+ page contracts all day with lightening speed. The other place i came accross them was at a medical center where patient forms were scanned in while the patient checked in. They were extremely reliable.

Interesting.
Try strace wget http://127.0.0.1/; and see which system calls are failing.
My guess is bad permissions on /dev, /sys or /proc. Backup guesses are:
something to do with selinux, out of memory, bad capabilities, or some

interesting bits. not quite sure what it means at this stage.

this appears to be the only piece of information ifconfig doesnt
display to regular users.
and this is strace of ifconfig run as root
unlike the strace run as the regular user this strace didnt show any

Hi Peter, You're absolutely right. I was tired as hell when i posted the email last night and realised this morning in the shower the real error was the one you pointed out.

Re: [SLUG] non-root users cant use network [FIXED]
SUCCESS! regular users can see all info from /sbin/ifconfig, ping 127.0.0.1 gets replies, and wget no longer throws Permission denied. I had been trying to figure this problem out for months. I thought the only customisations made to the kernel were around the hardware - ARM SOC platforms, integrated peripherals, etc. I didnt have any clue that extra network security bits had been added.

Re: [SLUG] non-root users cant use network
Problem resolved.
but for your amusement heres some info about the netbook and processor.
It features a WonderMedia 8505 SOC which is an ARM926EJ-S rev 5
compatible proc. 174.48bogomips, features swp, half, thumb, fastmult,
edsp, java
From what I understand the thumb and java features mean it can execute
native ARM and Java bytecode.
Its got a whole 128Megs of ram, or more like 100megs usable after the
kernel and everything is loaded. It'll start to swap when using
Aptitude :)
its got 2gig nand flash as internal storage which is presented to the
system as a usb disk...so booting is nice and fast - /dev/sda2
rootdelay=7 :|
built-in fastethernet and b/g wifi
Thanks again for your help.

Your problem is definitely in the kernel, and not locales (which is just
message printing). But just why the kernel is refusing to create a TCP

Can you send the contents of /proc/net/dev please.
Is there a way you can find out what kernel capabilities your process has?

[SLUG] non-root users cant use network
Hi everyone, I'm fairly new to the list. I've got what I would consider an interesting issue with a little netbook I've been playing around with. basically regular users cannot make any outbound network connections. for example: cpbarnes@netbook:~$ ping 127.0.0.1 socket: Permission denied and cpbarnes@netbook:~$ wget http://127.0.0.1/ Connecting to 127.0.0.1:80... failed: Permission denied. doing the same as root works. Interestingly when i do: root@netbook:~# /sbin/ifconfig i can see the loopback interface AND its ip address 127.0.0.1 however as a regular user i get: warning: no inet socket available: no such file or directory i can see the loopback interface but there is no ip address. heres a little background. The netbook features an ARM processor, 128meg RAM, and the main storage is a USB thumb drive wired straight on to the mainboard. It came pre-loaded with Windows CE 6 however, as stunning and feature rich as it was, i got my hands on the vendors linux install for the netbook and installed that. The vendors Linux install is Debian based, ive got 2 varients, Debian 5 and Debian 6. Both present the same problem. I've tried updating the installed packages but the problem persists. The Linux kernel supplied appears to be a customised 2.6 and pretty much all the modules are compiled in. ive done a stack of searching on the interwebs. a lot of people talk about needing to setuid on the ping bin, but this is already done root@netbook:~# ls -l /bin/ping -rwsr-xr-x 1 root root 34984 oct 14 2010 /bin/ping and besides, its not just ping that isnt working. i get this problem with the loopback interface, with the ethernet interface, and with the wireless interface. /sbin/route shows no entries, not even locally connected networks but even after adding one problem persists. e.g. route add -net 127.0.0.0/8 lo some people have also suggested ip tables could be the problem but as far as I can tell no rules are installed. it doesnt even look like iptables support is compiled into the kernel root@netbook:~# /sbin/iptables -L iptables v1.4.8: can't initialize iptables table `filter`: iptables who? (do you need insmod?) Perhaps iptables or your kernel needs to be upgraded. I've never seen a problem like this. Does anyone have any ideas or suggestions on what to look for or what to try next?

Hi Nigel,
You shouldn't be quoting the escaped string. Due to the fact that

Re: [SLUG] Escaping illegal characters in filenames - how?
I've got an idiot user who has created a file on a Linux filesystem named -.mxf I need to rename this file, but can't for the life of me remember how to escape the - character so mv doesn't regard it as an option identifier. Insert ./ in front of it so mv doesn't see the - at the beginning of the string and tries to interpret it as a flag. So the command could be mv ./-.mxf newname.mxf. Another way that you may find handy in the future when using system utilities is the -- argument eg: rm -- -filname. The example removes the file -filename. The argument -- often signifies end of arguments, and anything after that is translated as non-arguments to the command. It's used quite a bit in GNU tools, and I'd guess maybe more tools.

Re: [SLUG] Debian Lenny HAL Config
Hello Rodolfo,
That works!
After reading some documentation, I have found that pluralisation of
anything means that the search looks for matches further up the tree.
The match does not have to be on the local node. So ATTR matches this
node and ATTRS matches up the tree. Same for DEVICE and DEVICES.
Your description of the relationship between HAL and UDEV makes sense.
A small issue I have now is that when I remove and reinsert the TOSHIBA
device, df reports the file system is mounted twice. It's still usable
though.
When the device is removed, it does cause /dev/toshiba1 and
/mnt/toshiba1to be removed, thus leaving /mnt/thoshiba1 high and dry.
It seems there needs to be a remove event triggered to perform the umount.
Thanks and regards,
Chris.
Rodolfo Martínez wrote:
Hi Chris,
As with almost any other software, developers will ask you to test the
latest version. I think HAL reads the gconf configuration correctly
since 5.14. Anyway, don't spend too much time with HAL; it is
deprecated.
udev is a device manager. It creates the files (device nodes) in the
/dev/ directory and doesn't care what you do with the device. For
example, it creates the /dev/sdb* devices and that's it. With udev you
can setup the permission for the *device node*, but you cannot specify
how to mount the device.
hal is intermediate/extra layer between the physical devices (/dev/*)
and the applications that allows the applications to use the hardware
without knowing anything about the physical device.
This is how I would achieve what you want to do:
1. Create a udev rule to rename the block device.
2. Specify the mount options in the /etc/fstab using the new device name.
1. The udev rule:
Create the file /etc/udev/rules.d/99-usb.rules with the following lines:
KERNEL==sd?, BUS==usb, ATTRS{serial}==0220787042A168B4, NAME=toshiba
KERNEL==sd?1, BUS==usb, ATTRS{serial}==0220787042A168B4, NAME=toshiba1
2. The mount options:
Add the following line to the /etc/fstab file
/dev/toshiba1 /mnt/toshiba1 vfat
defaults,user,noauto,uid=1000,gid=1004,noatime 0 0
and create the directory /mnt/thoshiba1
From now on, it doesn't matter who mounts the device, it will be
mounted under /mnt/toshiba1 with the desired options.
BTW, what/why is there a difference between SUBSYSTEM and SUBSYSTEMS?
SUBSYSTEMS is plural :P
Not sure, I have never used SUBSYSTEMS.

Re: [SLUG] Debian Lenny HAL Config
Rodolfo,
This did the trick. You would not believe how close I was to working
this out before. I was just missing the =. Oh well.
The hal version:
peterpan:/etc/hal/fdi/policy# hald --version
HAL package version: 0.5.11
I guess the problem I am experiencing is a bug on the package. Are you
a good person to take this information to the appropriate Team?
I have spent some time attempting to figure out the relationship between
udev and hal. It seems that udev gets things first and passes a result
to hal. Right? I say this because the last udev rule says:
RUN+=socket:/org/freedesktop/hal/udev_event
It also seems to me that udev sets the group permissions for the mount
command, but the config in gconf (as used by hal) was blanking it out.
If this is right I must say I had lots of trouble working it out because
I cannot figure how to insert and use debug statements to check things,
or where low level logging might go.
If you could assist with a udev rule to permanently mount a usb card for
my user, I would really appreciate it. As I said I have made a few
tentative additions to existing rules and observed no discernible change
in system behavior. I'm looking at:
http://reactivated.net/writing_udev_rules.html

Hi Chris,
The line should be:
append key=volume.mount.valid_options type=strlistgid=/append
Note the '=' after 'gid'. The '=' means that HAL accept any value for that key.
And the gconf mount options should include 'gid=1004'.
On a related but different topic, how do I force hal to always mount the usb
card as me (chris). I am not the only user on the console, I have to play
round robin and a game of chance for the card to be mounted under my uid.
The only solution for this is to specify the mount options (uid, gid,
etc.) in /etc/fstab. HAL will search for an entry that matches the
device that will be mounted, if none matches, it will mount the device
using the default values/options. The default is to mount the device
on behalf of the user that invoked the mount petition.
The problem is that the device block won't be always the same, it
could be /dev/sdc1, /dev/sdd1 and so on, but this can be easy
addressed with a udev rule, let me know if you need help with this.
BTW, what version of HAL are you using?

For a GUI application, I believe Pan (http://pan.rebelbase.com/) is supporting NZB files nowadays. -Chris-- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] IE on Ubunto
I have Ubuntu 9.10 installed and use Firefox for browsing the web. Every so often some one tells me You must look at this but this is coded for IE only. I am not inclined to buy another PC just to look at the occasional web site in IE Is there a simple solution (cheap) to this dilemma?

Re: [SLUG] Overheating
Have you noticed a difference when you run or don't run certain programs? I had big overheating problems, which I finally solved by installing Flashblock on Firefox. It was a case of too many tabs plus flash not running well in Linux. Before I discovered Flashblock, I took to stopping whatever applications were using the most CPU% according to my task manager, which was usually Firefox (in the task manager, right click - stop, so I could easily restart again the same way). The temperature would drop very quickly.

Is this a laptop or a desktop PC? What are the CPU and GPU chips? Desktop. The CPU fan has been removed and replaced twice. Under load it jumps from 30 to 40 and with a hot ambient (no aircon at all) climbs to 80 and stops. Right now sitting on 29 and 26. The Nvidia card has a lot of cowling around the fans so I wonder how clogged it will be. Previously I had carpet and was in Campsie which was bad for dust. In summary: - I will try and clean the heatsink on the Nvidia without removing it and no worry too much. - I will clean off grey goo on CPU and replace it with a thermal paste.

I need to copy ALL the files across. cp (or rsync, depending on your circumstances) would work between filesystems.
