We are running the bsd-named supplied with 10.2 on our gateway-node (DN3500)
and on a DN3010, both as secondary servers, since the administration of our
subdomain is done by our 'parent'-domain ( long live bureaucracy I. !!! ).
After experiencing irregular host-resolution-failures ( ~ every 15 minutes for
some minutes ) I queried our named's with help of nslookup (not supplied with
Domain/OS) from an Ultrix-host, and came up with something like ( set debug ).
Got answer : Type is A (actually longer ..)
timeout1
timeout2
timeout3
timeout4
While I'm not a great binder I assume that a successful resolution consists of
at least _two_ packets from the server, and that the Apollo-named sometimes
messes up with the second one .....
the named.run-logfile showed the query, but nothing unusual ...
Two questions :
o has anybody else experienced such failures and can provide me with
some enlightment concerning my idle 2-packets-speculation ?
o is there a remedy -- or am I just plain wrong ?

We are using named recompiled from original source, and don't see these errors. If you want the source, let me know. (We also use sendmail recompiled from source, since the sendmail/named supplied before 10.2 will not work, and we ain't taking any more chances :-) ). -- Mike Peterson, System Administrator, U/Toronto Department of Chemistry E-mail: system@alchemy.chem.utoronto.ca Tel: (416) 978-7094 Fax: (416) 978-8775
