Description Bryn M. Reeves 2008-07-14 14:49:52 UTC
+++ This bug was initially created as a clone of Bug #454703 +++

Description of problem:
The netdump server uses a hard coded remote port when replying to netdump clients:

netdump_client_send_reboot ()
  addr.sin_port = htons(NETDUMP_PORT);
  addr.sin_addr.s_addr = htonl(reboot->ip);

netdump_client_send_request ()
  addr.sin_port = htons(NETDUMP_PORT);
  addr.sin_addr.s_addr = htonl(client->ip);

This prevents the server communicating with clients that have defined a
non-default LOCALPORT in /etc/sysconfig/netdump.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Configure a netdump client with LOCALPORT!=6666
2. Force a crash on the client

Actual results:
Netdump server replies to port 6666, netdump handshake fails

Expected results:
Netdump server replies to the client's LOCALPORT

netdump-server-0.7.16-22.el5 is in EPEL-5 now and claims to fix this issue so I'm closing off this bug.  Feel free to reopen the bug if you're still having problems.
