Hi again

	Now that I have the latest version of (t)ethereal running on my
system I've another question.  When I pipe STDOUT of another packet capture
program to STDIN of tethereal it quits running after several packets and
returns to the shell.

For example:

tcpdump -n -w- | tethereal -n -p -r-

OR

tcpdump -n -w- | tcpdpriv -p -q -A99 -C99 -M99 -P99 -r- -w- 2>&/dev/null | \
tethereal -n -p -r- -F ngsniffer -w capture.all.enc

	However if I perform the same operation but substitute tcpdump it
continues to function for as long as needed.

tcpdump -n -w- | tcpdpriv -p -q -A99 -C99 -M99 -P99 -r- -w- 2>&/dev/null | \
tcpdump -n -p -r- -w capture.all.pcap

	I'm trying to do this in an all in one process to avoid creating an
intermediate file when trying to create a packet capture with no data that
is readable by Distributed Sniffer Pro(tm).  This is on an i686 OpenBSD
system.

thanks again,
