Red Hat Bugzilla – Bug 6807
Pump does not connect to cable modem network
Last modified: 2008-05-01 11:37:52 EDT
Pump does not start-up dhcp client with hostname parameter.
Since pump but not dhcpcd is loaded by a default Red Hat
installation, it is very difficult for the novice linux user
to configure Red Hat 6.1 with cable modem connected to @home
network. With the default installation eth0 always FAILED
during bootup after waiting for an enormously long time-out
period. I had to remove pump and install a simple shell
script to get my dhcp working the @home network using
dhcpcd. I also had to perform an ifconfig with a unique
netmask assignment. Here is the shell script I used:
ifconfig eth0 <hostname> netmask 255.255.255.0 broadcast
/sbin/dhcpcd -h <hostname> &
I called this file mydhcp and I created the following link:
ln -s /sbin/mydhcp /sbin/pump
The 24.x.x.x network defaults to a 255.0.0.0 netmask. And
@home requires a "hostname" to access the network. Of
course, San Diego's cox@home "doesn't "support" linux
This was reported to Red Hat support as Reference #:
991015-0068, but was referred to submit this bug report.
The last support mail I received said this:
My name is Marty and I am a Level 2 technician. I did some
looking and asking concerning pump's behavior, and I haven't
found any known issues that fit this situation.
I urge you to please open a bug report describing the
initial problem and the workaround so that our developers
(who wrote pump) can address the issue.
I apologize that we cannot find a better solution. This may
be an isolated case, since there are no existing bug
reports, but it certainly doesn't mean you're the only one
with the problem.
I am closing this incident.
So here is the bug report. I hope you are able to develop a
better fix for pump rather just disabling it. I noticed
that even in the mini-DHCP HOW-TO pump is not used for dhcp
client either. Does it have to be this way? If you do
an Internet search on (@home, dhcp, and linux) you will find
a lot of cable modem users are having problems with pump.
Good luck, and let me know how it turns out. Thanks!
(If you do not have access to the Red Hat incident report
just e-mail me and I will be happy to forward the transcript
of our entire incident report).

I have this exact same problem with MediaOne/RoadRunner cable internet, and with
some of the DHCP servers at Boston University. It's definitely not an isolated
could you test this with pump-0.7.6? I think I have all the hostname stuff
worked out now, and the new release seems to have helped many folks.
If this doesn't fix the problem, please reopen this bug.
