I tried to port the BSD ping program to my Data General Aviion, which
is running SVR4 (DG/UX 5.4.1). It appears that there is some sort of
problem with raw sockets or ICMP protocol. I simply can't get the thing
to work. Every write results in an "invalid packet length" error, but
the packet length is what I would expect it to be.

I tried porting some other code to the box that uses raw sockets and
icmp and such - this time, if I bind() a socket, I get EINVAL, which
is supposed to indicate either the socket already has been bound, or
the name has an invalid length. Again, all the arguments to bind() and
socket() seem okay to me.

The programs compile and run with no difficulties on ESIX SVR4 and
SunOS. Does anyone know of any specific problems with Aviion raw
sockets or IMCP?

Please reply by email to me directly, as I rarely get to read email.
Thanks for your help!
