Version 5 servers now use kexec with a kdump facility mechanism that will allow for remote dumping of the core.* I'm not sure if netdump is functionally supported in your version of the kernel.

Subject: [Crash-utility] netdump issue
I am implementing a netdump . I crashed one sever and got the vmcore file in /var/crash/vmcore*, then i checked the*kernel version through
strings vmcore | fgrep -m1 'Linux'
Linux version 2.4.21-40.ELsmp (email@example.com) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-54)) #1 SMP Thu Feb 2 22:22:39 EST 2006
So now while installing the kernel-debuginfo , it should match the version above i.e something like "kernel-debuginfo.18.104.22.168.ELsmp.i368.rpm"
But i installed the closest one and that was kernel-debuginfo.22.214.171.124.EL.i386.rpm but after installing them i should have /usr/lib/debug/module/vmlinux , which i could'nt see them .**
Can anyone give me the link to the rpm i am looking for , or suggest some idea. ( the server that i am dumping* vmcore*is version 5 )
I have bunch of server with version*2 and version 3* and version 4 in my production environment for which i have to configure netdump to collect the vmcore in version 5 server .
