I've a Sun-4 under 4.0 configured as a standalone and using YP (as a YP client). My machine is physically hooked to a net of Sun-3's -- the server (homogeneous) being a 3/180 under 3.3 (hence a 3.3 ypserv). On the surface, my 4.0 ypbind seems to work ok -- ypwhich was fine and so as ping, rusers, rcp, ..etc.. and I can telnet/ftp to other machines outside the immediate local net -- i.e. able to go to other depts' machines, ..etc.. However, when I do NFS mount, it just hang there (i.e. I type in mount by hand and it just hang there without even giving any error messages back -- i.e. no prompt back). The 3/180 server seems to be picking up the packets (I can see it in etherfind) but somehow it is not responding. If I kill my 4.0 ypbind on my Sun-4 and add the 3/180 server's internet address into the /etc/hosts file on my Sun-4 then I can do NFS mounts from my Sun-4 without a hitch (basically, I want to do NFS mount from my Sun-4 because all my home directory stuff is on the 3/180 server). I just got my Sun-4 recently (about 10 months ago) -- it was running SYS4-3.2 (also as a standalone & YP client) and was working fine before -- I only moved to 4.0 this week. The 3.3 ypserv on the 3/180 is working fine with other Sun-3 YP clients (a mix of 50's, 75's and a 280). The 3/180 server & other Sun-3's were here for more than 3 years so I don't think that it is a problem with the Sun-3's (there is only one YP server on the net and it is on the 3/180 -- i.e. the rest of the net are YP clients). Does anyone encountered similiar problems before ? Any pointers will be much appreciated. regards. -eric-
