If the kernel does not have the "Packet socket" and "Socket filtering" options enabled, pump will core dump. I haven't looked in the source, but I would guess it's getting an error return from a socket() call, and the error checking is done incorrectly or completely ignored. dhclient does the right thing, and exits gracefully while saying what kernel features should be present. I would never have made networking work without using dhclient (part of the isc dhcp distribution), since pump wouldn't tell me anything.
I have verified that compiling a kernel with the Packet Socket and Socket Filtering options turned off, pump will dump core when trying to initialize the network device. I have assigned this to a developer for further review.
*** Bug 4294 has been marked as a duplicate of this bug. *** pump dumps core when running with my own compiled 2.2.10 kernel. I could attach the core dump, if there only was a way to attach it. (I guess that would qualify as a bug/enhancement request for bugzilla).

After spending several hours trying to get my eth1 up with pump (DHCP via cable modem) I found out that my packet socket (AF_PACKET) was configured as module in kernel (tried versions 2.2.5-15 and 2.2.5-22 on RH6.0). After changing the packet socket option to be built-in feature, pump started working.
Jay, please build a kernel that exhibts this problem. It should be easy enough to fix.
Recompiling the kernel this way in 6.2, pump fails gracefully: [root@localhost /root]# /sbin/pump -i eth0 --status Operation failed. [root@localhost /root]# uname -a Linux localhost.localdomain 2.2.14-5.0 #1 Mon Apr 17 15:58:22 EDT 2000 i586 unknown [root@localhost /root]#
