Greetings,
I need to troubleshoot 'lookupd' and resolver behavior
on Darwin 8.11.0 (OS X 10.4.11); the target is a netbooted
G5 using only NFS mounts and no local mass storage. During
boot, test pings in /etc/rc work to resolve FQDNs until
'lookupd' is started, and fail thereafter. I have set up
'darwinbuild' and compiled the 'netinfo' package (contains
lookupd and the resolver libs) and with the new binaries,
the behavior persists. Previous experiments netbooting
Darwin 8.0.1 (from the Apple ISO) on this same machine
did not produce this behavior (resolver worked after
starting lookupd).
Kernel traces and 'lookup -d' output are here:
http://www.cybertheque.org/sw/darwin/lookupd-debug
A similar issue is mentioned on a number of IPhone development
websites but the workarounds don't work here. I would
appreciate insights from those folks more familiar
with the implementation and suggestions for introducing
debugging into the code for 'lookupd' and the resolver (and
perhaps appropriate libc routines).
Regards,
