We have an HP3000 and are using the NS3000 communications programs.
I have set up a proxy program on a Sun running solaris 2.3.  The sun
seems to ignore connections requests from the NS3000 software.  In
running a sniffer on the network it seems that the NS3000 client,
nvt, has a zero tcp checksum field.  I have looked at tcp source
code, tcp_input, and if a packet has a bad checksum it is dropped.
Does the HP set an incorrect tcp checksum field? or am I missing
something.
 
Thanks for any help.
