Hmmm ... ecc to elisha but then ecc to ecc. However, nmap -P0 ecclesiastes (by
IP address / from elisha) shows 631 open also. However, I don't think that
631 needs to be open on ecclesiastes ... it is only a client, not a server,
so the port being open or not is moot.

No, not that I could tell.

Huh? I'm not certain I understand the question. I set up the printer in the
GUI printer setup program (redhat-printer-config, I believe) on both
machines.

They are. The exchange went on for several minutes ... I just grabbed a
representative handful of entries.

Hmmm looks to me like only 127.0.0.1 can print, although any machine on the
network can browse for active printers. Is that how you read the text below?
