It turns out that there is yet one more bug in the packet filter
support in Ultrix 4.1 (the bug is not present in 4.0 or 4.2), which
makes it impossible to send packets via the packet filter.  (You get an
error message like "Address family not supported", I think.)  This
doesn't affect receive-only programs such as tcpdump, but CAP needs to
send packets.

The Customer Support Center does have a patch for this.  Ask for the
"net_common.o patch."  It is supposedly part of the kernel patches tar
file which is available from the CSC.
