Projects / ISC DHCP


The Internet Software Consortium DHCP distribution includes a DHCP client, a DHCP server, and a DHCP relay agent. DHCP is a protocol for automatically configuring nodes on an IP network. The ISC DHCP server and client are well known for being extremely configurable, reasonably easy to use, and quite efficient.

            It would be nice if this was released as source instead of a rpm. Need to realize that not everyone uses redhat.

            I had a problem with the dhcp.conf file that was located at /dhcp-3.0b1pl13/server/dhcpd.conf The sample file has the following line

            option name-servers,;

            which I believe should read

            option domain-name-servers,;

            Version 2.0 is out!
            I mention this because a previous comment says it's coming soon, but in fact it's here! :')

            Why use this one?
            This package contains both a client AND a server in case you didn't notice, and the client is the most flexible and configurable implementation around from what I can see. A major benefit is this program has an external shell script that gets called every time the lease is modified somehow, which should be perfect for people trying to maintain updated DNS information (like WINS integration, or roaming DNS services), since you can edit it to your heart's content. It's client also has no "issues" with NT DHCP server implementations, unlike another implementation I could name.
