But using MIT threads like you mentioned, they implement their own gethostby* routines. I think there is a more generic problem MIT pthreads does not consult the /etc/hosts file. I test program that runs on a machine in an isolated network: joy (nameserver) / \ rest of net isolated network the isolated network have /etc/hosts and does a host, bind search order. If i run a program that uses gethostbyname from libc, the correct IP number is returned for joy (the hidden network IP taken from /etc/hosts). test 2, if I resolve a name that has multiple DNS entries, the libc version returns them all. If i run a program that uses gethostbyname from MIT pthreads, the DNS derived IP number is returned for joy. for test 2, only the first IP number of a host that resolves to multiple addresses is returned. check the command, "nslookup localhost", by guess is that it does not have an entry and that is why the MIT pthreads gethostbyname call does not not return a value. --mark.
