Tom, Steve and George:
Thank you; the information you gave was helpful.
I checked a bit more; in short, eth0 does not come up on boot, but seems
to take a while--perhaps longer than Erich Titl's script allows. I've got
to check more on the script, as I'm not sure it delays as long as needed.
Restarting networking, esp eth0, brings it up fine, and then I can
manually launch dhcpd, after which all responds as it should. I'm able to
ping the eth0 address (192.168.1.254) both from itself and from another
machine (which obtained its IP from the dhcp server).
What I'd like to accomplish is having this all come up without having to
manually restart eth0 and dhcpd.
What I think is going on is that the version of Erich's script I'm using
doesn't wait 60 seconds, but runs to completion in about one second, so
eth0 is still not "up" before the boot process continues. Since eth0 isn't
yet up, networking, therefore dhcpd, don't work either. By the time boot
completes, eth0 is up, and manual restart of networking on eth0 and on
dhcpd work.
I suppose one test would be to add those commands to the
/etc/networking/interfaces file and see if they'll run there. I'll try
that and see what happens. Meantime, I'd sure appreciate some more
pointers.
In answer to Tom's question: I ran the ip addr ls both before and after
restarting networking, and captured the results below. I've used asterisks
to set off the different results.
