It just uses a system call and expects to get an answer within a reasonable time. The message "do_ypcall: clnt_call: RPC: Timed out" is coming from ypbind and indicates that NIS is not working as it should. Swapping the order of dns and nis in nsswitch.conf will probably get you going for this particular case, provided that dns is working. But the NIS problem is going to bite you sooner or later if you don't sort it out. -Thomas
