I am finding the 'got short packet from ...' in the system log on my
firewall machine. From the discussion on the mailing list last summer
(June 2002), I am not sure what is the appropriate action to take.
The basic setup is two RH 8.0 masquerading firewalls connecting two
LANs using cipe-1.4.5-11 (installed using rpm). For the majority of
connections, traffic seems to move cleanly between the two LANs. Only
when I run a molecular modelling program on one SGI that checks out a
license from another SGI on the other network do I see the message:
Mar 12 11:41:09 gateway kernal: cipcb75: got short packet from <peer ip>
Running ifconfig on the cipe interface shows an error rate on recieved
packets of around 10% ...

Other services, such as ssh and nfs appear to be functioning properly.
Any help would be greatly appreciated.
