I rebooted tia1 a number of times early this morning in an attempt to troubleshoot a strange NIS problem which unfortunately remains unresolved. Technical explanation follows: On this box, tia1 fails to bind with a ypserver via broadcast, it finds a server with ypset (and this is normally the way it functions anyway), but the fact that the former doesn't work and it does work on the other machines is troublesome. I went over the initialization scripts, they are same as on other machines, copied the binaries for ypserv and ypbind thinking maybe they had been mangled, (and they were old versions with some known security problems), but to no avail. The problem manifests itself in that the ypset command will not work with a specified hostname because the bind using broadcast for a ypserver failed, so it doesn't resolve the hostname 'tia1' (itself). Now, there are really two mysteries here; why the bind using broadcast fails, and why it can't resolve the host name when tia1 is in /etc/hosts AND the /etc/host.conf says to use hosts before NIS. The ypbind binary there is statically linked, so even if the dynamic resolver libs were munched this should still worked. It is one of three Sun4C machines, and the only one of the three running NIS. These machines are generally unstable but this particular machine has been stable. They have the Wytek Power-uP chips in them which apparently had some bugs, but none of that explains this behavior and I have to say at this point I am completely stumped.
