I am in the process of configuring an NIS server and setting up some client machines. Both machines are pretty much vanilla RH6.1 with updates. Authentication seems to work OK, since I have no trouble loggin in to my test client, and the common operational checks seem to work (i.e., ypcat, ypmatch, ypwhich). The problem is with yppasswd. When I try to change a password from an NIS client, I get: bash# yppasswd yppasswd: yppasswdd not running on NIS master host yppasswdd is running on the NIS server: bash# rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100004 2 udp 630 ypserv 100004 1 udp 630 ypserv 100004 2 tcp 633 ypserv 100004 1 tcp 633 ypserv 100009 1 udp 811 yppasswdd bash# ps ax | grep yppasswdd 7842 ?
