I had the same problem with ypbind, it works perfectly if i use broadcast (ie, i've server and clients in the same subnetwork), but if i specify a server on a different subnet throught ypserver, it hangs badly. i tried several version of yptools with no luck, so i think it's a libc problem. As i installed 2.1 it hanged my system and i had to boot from net (a pain!) regargs plasma
