Tuning the SQUID cache
Problem: internet access on the network is getting slow.
Possible causes: a filled-up proxy cache; lots of users accessing at the same time; a poorly tuned cache.
Solution: tune the proxy.
Requested for a user account to the proxy server. Her name's Maui -- the proxy, that is. Turns out the current admins access Maui as root. Bad, bad. So I made off with the user account, asked for the root account and promptly disabled SSH login through it, create a
Back at my workstation, I fired up puTTY SSH (nice tool, puTTY -- will try to do a review on it later on) and got into Maui. (Er, for the feminists out there, I'd like to remind you that the naming conventions of the servers are not mine. I would have preferred "Liv" or "Natalie" or even "Paris". *shrugs*)

Will have to check the access log to see what sites the users are visiting. No, this isn't to snoop on users, but to determine a metrics so frequently visited sites can be cached more efficiently.Took me the rest of the day groping Maui.
