Sorry to hear that.

You'd connect your newsreader and after that run "ps ax | grep leafnode"
(Linux and BSD-style systems) or "ps -ef | grep leafnode" (SysV style
systems) and use the number from the PID column (run ps ax without grep
to see which column it is) to pass to "strace -p".
If that doesn't do the failing operation, you'll use the same ps command
but grep for xinetd and attach:
strace -f -p 12345 (12345 is xinetd's PID here)
and then connect the newsreader after you've started strace.
