DHCP (again)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.|
22 August 1998It’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 kernelAfter 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 portWell, 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:
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.
