OK, this is looking like a firewall (ie. ipchains) setting issue.  I will have
to go learn how to do ipchains, and without a GUI since I didn't put it on
this box!

The output of "ipchains -L" gives:

Chain input (policy ACCEPT):

What line to I need to allow Webmin miniserv.pl to listen for https
connections on eth0?  Where do I put said line?

Mean while, I'll go read the manuals...
