So I figured my MTA is working, but my imap/pop3 server are screwed up. IE Courier is damaged. Now I use vexim to add users and vexim comes with some changes to /etc/courier/imapd - pop3d. All been detailed at the homepage.

Now im pretty sure I done the right modifications to imapd and pop3d. But I still cannot login and get mail. What could be wrong? /var/log/mail.log

Basic perl/bash help again.
I'm looking for a tiny script to rename one file, and that file is a webcam image that needs to be save every minute or so. That can be done in crontab.

So I'm really searching for the script to take /some/folder/webcam.jpg and make it /some/folder/webcam-TT-DD-YY.jpg

Found some old scripts wich are not working for me, I'm serious the worst bash/perl user ever!

The webcam image updates it self every 5 second. And after a couple of months I will make a time lapse video of my backyard. Pretty neat, eh?

And yeah, I've done a really extensive web search.

# This script connects to finance.yahoo.com and gets a stock quote for the
# ticker symbol specified on the command line. The result is multiplied by
# 100 so MRTG can deal with it.
#

use LWP;

$stock = $ARGV[0];
$browser_agent = "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2b) Gecko/20021029 Phoenix/0.4";

unless ( $stock ) {
	die "Please specify a stock ticker symbol!\n";
	}

$url = "http://finance.yahoo.com/d/quotes.csv?s=$stock&f=nl1d1t1c1vw&e=.csv";

$browser = LWP::UserAgent->new();
$browser->agent("$browser_agent");
$stock_quote = $browser->request(HTTP::Request->new(GET => $url));
if ($stock_quote->is_success) {
	@quote = split(/,/,$stock_quote->content);
	} else {
	die "Could not retrieve quote, exiting!\n";
	}

print $quote[1] * 100 . "\n";
print $quote[1] * 100 . "\n";

Kernels. And kernel update

Updating kernels on a remote server is the worst tasks I rarely encounter. But it has to be done. This time I was going to install mrtg on a server and startet with install gcc make g++. Then I saw this:

You might want to run `apt-get -f install'
to correct these.
The following packages have unmet dependencies: 
  kernel-image-2.6.8-1-386: Depends: initrd-tools
 (>= 0.1.63)  but it is not installed

 You are running a kernel (version 2.6.8-1-386)
 and attempting to remove the same version. 
 This is a potentially disastrous action. Not only
 will /boot/vmlinuz-2.6.8-1-386 be removed, making
 it impossible to boot it,
 (you will have to take action to change your 
 boot loader to boot a new kernel),
 it will also remove all modules under the directory 
 /lib/modules/2.6.8-1-386. Just having a copy of 
 the kernel image is not
 enough, you will have to replace the modules too.

    I repeat, this is very dangerous. If at all in doubt, 
    answer no. If you know exactly what you are doing,
    and are prepared to hose your system, then answer Yes.

Now, I know I've been a bit lazy with this server and never updating it, (only security) but I was waiting on a hardware update that never happend. So today I have all day with nothing to do so I figured I should fire up the ol'terminal and do some work.

It's a 933mhz P3 with a 2.6.8-1-386 kernel. Wich I guess is getting a bit old theese days. sources.list tells me it uses testing. (OK, I never understand the build names)

So in other words, I need a newer kernel. And making sure the system will boot up again.

Anyone have a few moments to help me out. (Again!)

(Atleast im installing mrtg on my own:D)

Why did I go for WD or USB 2.0 and not other brands and network storage is not the issue here.

But what kind of file system is preferred to have on such disks? I would really like a filesystem that *all* OS can write on, and not only linux. The disk will be used for a secondary backup for all my photos. And when I have the system up and running I'm hoping for a rsync line wich updates the files every day or something like that, in order to keep it 100% mirrored without me bothering with it. So, How do I mount it, and what FS to use?

Edit Are there any precautions I need to understand before doing this? Cause my main goal is to have a very safe and clean backup disk. Will a powersurge mount the disk properly on reboot? Can I destroy the FS on a surge? I'm kinda paranoid when it comes to backing up my pictures. (Of course, I have them all on dvd/other disks as well) But there is one thing I never run out of, and that is bad luck. So better safe than sorry.
