I recently ran chkrootkit and got the following line:
Searching for Suckit rootkit... Warning: /sbin/init INFECTED
What does this mean exactly? I heard this was a false positive, what is exactly happening.
Please and thank you.

I've been trying to follow these instructions, so that I could get the Citadel mail server to work alongside Apache, but I get an error when I try to restart Apache:
Invalid command 'ProxyPass', ...
I was told in the Apache docs that this is from the mod_proxy module, but apt-get install mod_proxy gives E: Couldn't find package mod_proxy, and I was unable to find it on the big list on the Apache site. What do I need to do to get the ProxyPass working in Ubuntu 10.04 TLS?

I have Ubuntu 10.04 32-bit with gcc 4.4.3 currently installed on it. I want to upgrade it to gcc/g++ 4.7 (I am looking for C++ 0x support)
How to update using Ubuntu Package Manager:
apt-get upgrade/install ??
As a second option I downloaded the latest gcc snapshot file from:
http://gcc.cybermirror.org/snapshots/LATEST-4.7/gcc-4.7-20110709.tar.bz2
Would doing
./configure
make
make install
on this package build and install it from source?

FreeBSD user joining your ranks. I've been asked to look after an Ubuntu Server running 10.04 LTS.
I see from /usr/lib/update-notifier/update-motd-updates-available that there are a number of updates on the server however I do not see a way to tell which will be updated.
Would anyone be able to point me in the right direction so as I can see which packages will get updated when I run apt-get upgrade?
UPDATE:
Can't answer my own question at the moment so throwing this in here for the time being:
Along with the apt-get upgrade --dry-run suggested below,
/usr/lib/update-notifier/apt-check -p will list all packages that have updates available.

I want to know which hard disk drive corresponds to which device path. It's trivial to match the hard disk stats (brand, size) with the dev path, but I want more. I want to know which drive is which inside my case. What's a good way to go about getting this info?
Constraints
- I am lazy. I don't want to tear apart my server to remove all the drives, then add back one by one.
- Reboots are acceptable.
- The drives are inconveniently scrunched together in the case. The label information is hidden.
- The case can be opened. Most disks are SATA, so theoretically hot swappable. Unplugging cables is fair game.
Bonus
I'll award answer to the best/easiest gui or cli answer, and give a bounty to the next-best answer of the other kind. I prefer a cli answer, but understand that a lot of other folks will appreciate a good point-and-click method.

Ubuntu 10.04
I have created this upstart script (/etc/init/pure-ftpd.conf):
# pure-ftpd - FTP server
description "Pure-FTPd server"
start on filesystem
stop on runlevel S
respawn
respawn limit 10 5
pid file /var/run/pure-ftpd.pid
console output
pre-start script
test -x /usr/local/sbin/pure-ftpd || { stop; exit 0; }
end script
exec /usr/local/sbin/pure-ftpd --maxclientsnumber 2 --maxclientsperip 10 --prohibitdotfileswrite --prohibitdotfilesread --noanonymous --chrooteveryone --dontresolve --nochmod --pidfile /var/run/pure-ftpd.pid
But...
# start pure-ftpd
start: Unknown job: pure-ftpd
and
# service pure-ftpd start
start: Unknown job: pure-ftpd
What's the problem?
Is it necessary to do something more?
Is it necessary to create one script in /etc/init.d too?
