The following are the best DHCP resources I have found. Most of these are specific to Road Runner cable service but should be applicable to any cable service. Please tell me about any other DHCP resources you find.
I would recommend the FreeBSD link below over what I've done. I think that article does a better job of documenting what needs to be done. My stuff is spread over several documents and should be consolidated into a single resource. At the moment, that is at the top of a long list of low priorities.
ISC Dynamic Host Configuration Protocol (DHCP)
Developers and maintainers of DHCP software. But use the ports first. See the next link.
Setting up a DHCP client on FreeBSD
Specific to FreeBSD.
Road Runner Cable Internet Modem Service
Contains a list of Road Runner cities with the login program for each.
RRLinux Help Site
For Linux, but again, should be universal.

It's time to reinstall the DHCP client. Again. Pity I can't get that other drive running. Then I'd just copy it from there. Shame, really.
Preparing the kernel
After almost a week off, I'm back into it. My next task is to install DHCP. My main resource for this procedure is
Setting up a DHCP client on FreeBSD
. I've followed it pretty much exactly as it appears. The key points are:
- recompile your kernel to contain:
pseudo-device bpfilter 4
- Make the necessary devices. But perhaps you should make sure they don't exist yet. Check the output from the ls bpf* below and make only those devices which don't appear.
# cd /dev
# ls bpf*
# ./MAKEDEV bpf0 bpf1 bpf2 bpf3
- Configure your /etc/dhclient.conf file.
# cp /usr/ports/net/isc-dhcp2/work/dhcp-2.0b1pl0/client/dhclient.conf /etc
Compiling the port
Well, the
DHCP install instructions
do say that DHCP is not straighforward to install. And it isn't. But I did the following and used CD #3 of FreeBSD 2.2.7.
Please note, that the following instructions contain extra steps. See
Building a port - background info on make
for more concise information.
# mount -t cd9660 /dev/wcd0c /cdrom
# mkdir /usr/ports
# cd /usr/ports
# ln -s /cdrom/ports/distfiles distfiles
# cd /usr/ports/net/isc-dhcp2
# make
# make install
After all of that, it took me a while to figure out where the results were. I knew the stuff had been built, but where was it? [
see below
for more information about this search]. I found out by doing the following:
find dhclient . | grep dhclient
Which showed that what I wanted was to be found in:
/usr/ports/net/isc-dhcp2/work/dhcp-2.0b1p16/client
After going to that directory, I issued the dhclient ed0 command. And surprise surprise surprise! It worked.
NOTE: You might also want to use the locate command.
4 October 1998
I've been given some information about the make process above. I had written that I was unable to locate the executable file after the "make install" had been run. It turns out that dhclient is copied to /usr/local/sbin. The copy I found in the work directory would be removed after doing a make clean.
