I am administrating a network for a group of programmers developing a web spider.
We want to setup a squid cache so to be nicer to all those servers in the web. (And also so that our tests run faster).
The configuration we need is very easy: Cache everything for 30 minutes, no matter what (ignore last modified, e-tag, etc).
How do we do that?
what is the easiest way to get a host's canonical host name from linux's command line?
If it matters, my shell is bash.
CLARIFICATION: I want another host's canonical hostname, either by ip or by non canonical hostname. Not the local host's canonical hostname.
I have ubuntu 8.04 and I want to write a bash script that runs as root which every user can run.
I myself can do sudo.
How do I do that?
CLARIFICATION: I don't want to do it with sudo, because then users will have to type their password. I just want them to run the script as root, perhaps something setuid, dunno.
What is a sensible logs policy?
On one hand I would like to keep everything forever. On the other hand I don't want to waste time in administrative tasks and must avoid disks getting full in production servers.
What is a sensible logs policy? What tools are there (free or not) to help you implement the policy.
I want an easy way in linux to kill all my current processes.
