HOWTO: dhcp
Description: ISC Dynamic Host Configuration Protocol client and server
Click here for ChangeLog
NOTE: I use GNU tar >= 1.13.25 so it's -j for .tar.bz2 files,
it's safe to assume that make, gcc, binutils, fileutils/coreutils, gawk, sed, and grep are prerequisites for almost everything
# ISC DHCP 3.1.3
# ==============
# Slackware 12.0: dhcp 3.0.5
# Slackware 12.1, 12.2: dhcp 3.0.6
# Slackware 13.0: dhcp 3.1.2p1
# When upgrading from one DHCP version to another, you may need to blow away
# (or modify) your old leases file due file format incompatibilities between
# versions. Check the release notes for differences between the version
# that you're running and the one you're about to install.
# There are also 4.0.x and 4.1.x releases available, but I'm sticking with
# this one for right now. I will probably add a 2nd release to this howto
# next time I update it. Version 3.0.x is EOL as of March 2009.

# Read 'man dhclient' and 'man dhclient.conf'
#
# Check out sample server configuration:
# ~/src/dhcp-3.1.3/server/dhcpd.conf
# Read 'man dhcpd' and 'man dhcpd.conf'
# Here is a sample /etc/dhclient.conf that I use with dhclient to get a
# dynamic IP address from my cable internet provider (Comcast).
#
# interface "eth0" {
# supersede domain-name "englanders.us";
# prepend domain-name-servers 192.168.123.2, 192.168.123.1;
# require subnet-mask, routers;
# }
#
# It causes a few things to be changed in /etc/resolv.conf It uses my
# domain instead of theirs, and it lists my internal DNS servers
# (192.168.123.x) before theirs (1.2.3.x). Here's an example of a
# resolv.conf that it creates:
#
# search englanders.us
# nameserver 192.168.123.2
# nameserver 192.168.123.1
# nameserver 1.2.3.4
# nameserver 1.2.3.5
# nameserver 1.2.3.6
# My dhcp server configuration is way too complicated to post here, I use
# failover, dynamic DNS, etc. If you'd like to see it, e-mail me and I'll
# send it to you.
# If you ever need to uninstall DHCP, run this:
