I not positive that this will fix it, but theoretically it should work here if name resolution is the problem. In any case, it's alternative that you might try. (1) We run the the bind name daemon (named) here, and from the *.bak files that are kept for the local zones, I have the machine construct a new /etc/hosts file every night - so this hosts file contains the local domain hosts (plus whatever hard wired stuff you want like "localhost 127.0.0.1"). (2) WRT host reslotion, I have the following set up. === /usr/etc/resolv.conf === domain mmwb.ucsf.EDU hostresorder local bind nameserver 0.0.0.0 === So that the /etc/hosts file will be queried first - and local references should be resolved by that lookup. For us, it helps with two conditions: (1) Mounts and exports at boot time. By the time our machines reach the phase of the boot where mounts and exports are being performed, named hasn't completely loaded. Just makes the boot a little cleaner, and less dependent on DNS. (2) When the named caches have gone stale and/or athoritative host for our zone(s) is unreachable, this allows local resolutions to work. I think it might also solve the above syslogd apparent resolution problem. Hope this helps. - Scott Presnell -- Scott Presnell +1 (415) 476-9890 Pharm.
