[SLUG] urgent! Hard disc dissapeared.
I was doing some recording using audacity, when i tried to save a project, the system froze and i could not switch to a console to shut the machine down, so i had to use the reset button and after this my system could not boot up anymore, it could not a mount the hard disk which i mount to /home ... the error message reads The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap of ufs or something else), then the superblock is currupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 then i log into the rescue mode and the /dev/hdb1 is not there. what is going on here? googling didn't give me much more information. i have all my data on this disk and only have a partial backup ... can anyone please help me? thanks a lot urgent!

if (chdir(path) == 0)
{

}
else
{

So why eschew the same when programming in the shell?

Re: [SLUG] Script Help
Yeah, I replied, but not to the list. It follows: // begin reply // Still, the previous reply makes an interesting point that I overlooked. Using star in "rm -r" is reckless, in general. But by issuing a "rm -rf $name" will remove the directory along with it's contents, whereas "rm -rf $name/*" wipes only the content out. Up to you to decide what's best. A little bit paranoia =) , but since the subject always leaves us a bunch of options, maybe it's worth mentioning: given the fact that this is probably a non-interactive app, we're assuming a line will never contain a front-slash plus some other folder name. One fine day, the app finds a line containing "/etc", you'll end up removing /etc/*. Empty lines should not be a problem because bash (and I don't know what's the behavior of shells in this case) will ignore them. That goes with the user you're running the script as, possibility of such line getting into the file, and lots of things you guys probably know. My "I-owe-you-2-cents" tip.

Re: [SLUG] Script Help
> Why is the following script ripping out every directory rather than just > those in 'studentfile' You mean "studentlist"? Anyway, you could try: $ for dirname in `cat studentlist`; do rm -rf $dirname/*; done Will remove everything inside each folder listed in a file called studentlist, located in the same directory you're running the script.

Re: [SLUG] GD with php and apache
Ok as per Murphys requirements, I've found the answer 5 minutes after posting. Must install php-gd rpm. This doesn't appear in the rpm database on the older FC3 box I guess they've split up of php into more rpm's.

Re: [SLUG] GD with php and apache
Kind of... "Call to undefined function" means PHP is not loading the extension at all. So we can start here. Can't you run phpinfo()? I found a typo on your example down there. > phpinfo(); > ?> Should be: If phpinfo() doesn't do anything, it's more serious than just GD not running. I have no source knowledge to tell why this would be happening, IF this is happening. First of all, try to figure out what's going on with phpinfo(), and then, if you manage to get it working, check the output to see if GD is loaded. And last, compile it from source if you're still having problems. I never had issues when doing so.

The UoW CompSci department uses a fairly standard Debian install, so this installfest will be using Ubuntu. Volunteer demonstrators are required on one or both days to help out with the hardware compatibility issues that are likely to crop up, and to demonstrate some of the basic configuration tasks that students will need to do once they take their shiny new systems home.

RE: [SLUG] Squid: Sometimes files stop downloading after 1 mb
I have looked through the config file and it is all defaults. I tried setting reply_body_max_size 0 And that didn't work (I think the documentation is wrong on this) because you need an allow line. reply_body_max_size 0 allow all Works but doesn't fix the problem. Likewise Reply_body_max_size 9 allow all Also doesn't fix it. Not at work and can't SSH for some reason but I looked at the machine and there was no major resource usage. It has 512mb ram, not sure about the processor. It started happening recently but I'm not sure which update caused it, because it is an intermittent problem.
