I'm at my wit's end (yes, that's a singular wit -- all I have left :). I
have 2 RH boxes, a 6.1 and a 6.2, both running kernel 2.2.16-3. Both are
configured identically as far as dhcpd is concerned (as far as I can tell),
yet the 6.1 box works and the 6.2 doesn't. The 6.2 box starts dhcpd
successfully, then later (still pre-login) kills it due to no definition for
eth1 0.0.0.0 (huh??????). I can't find where this net is being defined,
assuming that's the cause. Of course the 6.2 box is the "real" one, and the
6.1 box was for testing purposes only, and they can't be swapped. :(
After startup, if I login and then run '/etc/rc.d/init.d/dhcpd start', all
is OK. Of course, this is not adequate, as I won't be at the client's 24/7
waiting for power outages.
Relevant config files follow, as well as /var/log/messages for both
machines. Looking for where to look next -- see **[...] for my comments.
TIA...
