We've modified a copy of 4.3bsd ping to just watch icmps
received; ie, not ping, just watch.  We've got it running
on our gateway, a vax running 4.3bsd.  We'd also like to
see icmps being forwarded through the vax.  Any suggestions?
Maybe using some socket type other than SOCK_RAW?  Or maybe
4.3bsd just doesn't give applications a chance to get their
hands on packets being forwarded?

Thanks,
