Hi Gerald,

I was able to decipher a bit.  Towards the end of your tcpdump, where
there is "UDP, length: 59", these are three identical packets being sent
 from ipmipower called the "activate session" commands.

When a response isn't received from the remote system for that
particular packet, its usually b/c your password is incorrect.  There
are several other possible configuration issues on the remote system
that can cause this, but they are less common.

Did you happen to use 'bmc-config' to configure the remote system?  I
did find a bug sometime ago that could affect the password configuration.

There is also always the possibility the IPMI implementation on the IBM
servers is out of spec.  If you can't run ipmipower with --debug and
--ipmidump, could you take a tcpdump with a larger snap length?  Perhaps
"-s 256" so I can see all of the packet information?

Thanks,
Al
