Re: Kernel 2.4.25 upgrade broke my network

[Joe Carey <joe.carey@fidelity-comtech.com>]

Thanks, your response was very helpful.

After poking around a little more based on some ideas that came to me as 
a result of your e-mail, I realized that the only thing broken (that 
I've noticed so far) was the dhcp-client.  It appears to be that it 
didn't get upgraded with the Sid update.  For some reason, dhcp is 
working with the 2.2 kernel but not with the 2.4 kernel.  There is a 
newer version of dhcp-client on the debian server, but apt-get gives me 
errors when I try to install it (for some reason it conflicts with 
Mozilla - go figure).

I'll poke around some more with apt-get options and get it working.

Thanks again.
