Thanks for the info, KC. Here's the output of ior-decode-2:

I don't have a FQDN for this machine, just a hostname
"jupiter." No
firewalls, just a few machines connected to an SMC 4 port
router. I
looked up Debian's suggested method of setting the FQDN:
(http://www.debian.org/doc/manuals/reference/ch-ga
teway.en.html.) I'll
have to try that.
TML in a subsequent message states this problem is fixed in
CVS. I'll
have to get the source and compile when I have more time and
check this
inter-machine communication using echo-client/echo-server
again soon.
