Re: Problem with DHCP when using tokenring on 2.4.x

[Mulder, Tjeerd]

The problem is probably caused by a change that was made around
kernel 2.3.29. The hardware type of a tokenring adapter was changed
from ARPHRD_IEEE802 to ARPHRD_IEEE802_TR. That breaks pump and the
ISC dhcp package. So pump from RH6.2 certainly won't work.

Fixing the ISC dhcp package is easy. Maybe it has been fixed
on the ISC site by now. Don't know about pump.

Try at least stracing pump and find out _which_ operation fails.

Then find out where in the source there are messages "operation
failed" and whatever messages are around that message and compare
these positions with the call trace you get from strace and an
static analysis of the code paths leading to this message.

As a last resort try to run a debugger over pump (you have to
rebuild it without optimization and with debugging symbols).

This sounds like an user space problem until now, but once you
tried all this, we can decide whether it is a kernel bug or a bug
in pump, which got triggered by more correct behavior of the
lastest kernels.

Problem with DHCP when using tokenring on 2.4.x

[mshiju]

Hello,
   I have a problem with DHCP when using tokenring card on 2.4.x
kernel . When I am using IBM tokenring adapter( all) and trying to hook on
to the lan n/w using DHCP ,I get an error message "operation failed " from
the dhcp client . The dhcp server is getting the broadcast message when the
dhcp client  is run. I am using pump that comes with 6.2 redhat
distribution .  There is no problem when using static IP.  I could
experience this problem only  on 2.4.x . I am able to get a valid IP
address on  2.2.x kernel when using tokenring adapter. And also there is no
problem when using ethernet adapter on 2.4.x . . Has anyone experienced
this problem on 2.4.x . Can any one help me to resolve this problem.

Thanks & Regards
Shiju
