OK! This and a reboot (with a series of iptables temporarily unavailable
messages) got it working and I saw the text that expected to see. The network
was working correctly on startup. BTW, the netcardconfig utility asks for and
places all three lines, not just the netmask, and also removes/omits the
other, auto and allow lines. So replacing this very very old utility is part
of the cleanup.
The scripts are run fine. I still cannot get my imap server from outside
(formerly corrected by (re-)running the rc.firewall script (from guarddog) but
that may be another problem. I do have port 143 forwarded in the router.
