Same here - first ever useful Linux box I installed, configured from
scratch. It took a good while to get the hang of the packages, but I was
able to re-install it and get it running in a few hours after a hard disk
failure, without having a backup to restore from. (I said I was a newbie)
It's very low maintenance.
The setup was RH 6.2, with squid, ipchains and a caching nameserver.
Originally I used diald to handle dialling on demand, but after the
reinstall I didn't bother with it, using the demand option in ppp. Red Hat
don't tell you about this (didn't at the time anyway) but it's a must.
The upgrade to RH 7.2 when it came out was a doddle. The only problems were
that it broke demand dialling and wiped the firewall rules, but I was able
to get demand working again by tweaking a few scripts, and I had a backup of
It keeps itself patched too, via RHN and a simple home made cron job which
runs every night.
A few tips (YMMV) -
Read up on the packages you'll be using. Read up on security. Get your
distro patched before you put it live. Use a packet filter. Use ISDN (or
DSL if you can get it). Make a backup.
Don't use a leased line. Don't get a static IP address (it attracts
rodents). Don't put up with an analogue line unless there'll be only one or
two users. Don't create lots of user accounts. Don't run packages/services
you don't need. Don't buy new hardware - you won't need it. A few gig (we
have 25 users and our 9 gig disk is mostly empty)of hard disk space will do
Hope that helps
