It seems that either box that I run ypbind on causes network statistics to take a *very* long time (rpcstat -p finally finished 7-8 hours after I started it (listing 12 entries). I started ypbind on the server box, and it also takes forever to complete the rpcstat as well as netstat. When I disable it again, things return to normal. Running ypserv in debug mode didn't really help. ypserv does not produce any output when I try to run ypbin/ypcat. Again -- I am able to run ypbind from the same machine that ypserv is running on. If I run ypbind from the client (10.0.0.2), a lot of network activity (maybe just UDP?) grinds nearly to a complete stop. hrm... any ideas? > > > > I have enabled portmap on both ends in rc.conf. > > > > I have allowed portmap in hosts.allow for each of them from the other > > and from itself. > > > > I have added `nis' to host.conf on both client and server. > > > > I have added an entry for `chris-nis' in hosts which points to > > 10.0.0.1 on both the client and the server. > > > > I started out following the instructions given in the handbook, but > > when they didn't work searched the archives and freebsddiary.org, and > > found several different ways to set it up.
