ypserv problem

ypserv problem

[Luca Ferrari]

Hi,
I've got a quite classical situation: linux server (suse 9.1) holding accounts 
and homes with yp and nfs+automount. Sometimes loggin in from a solaris 
client is very slow, even if it works. Watching the logs, I found a few lines 
like the followings:

Sep 16 10:49:22 mammuth ypserv[2024]: refused connect from X.X.X.X:32793 to 
procedureypproc_match (nis_domain.gamma,passwd.byuid;-1)

I've searched the internet for this problem, but I didn't find a solution. 
I've noticed that the problem seems to be related only to the sun clients, 
even if sometimes the server itself is slow accepting interactive sessions on 
the console. My nsswitch.conf file on the server contains:
 passwd: files nis
 shadow: files nis
 group:  files nis
and the same on the suns. The machine is the nis master server, no slaves are 
configured now. The fact very strange is that, even if all the machine have a 
name and the dns works fine, in the log I found iP addresses and not names. 
Even placing the host name in the /etc/hosts file does not solve the problem.
Any suggestion?

Thanks,
Luca

I've found another issue: on Linux clients using gnome, the user logs in but 
the window system seems to be frozen. The .gnome-errors file contains lines 
like the following:
GLib-WARNING **: getpwuid_r(): failed due to: No such user 4136.

Gdk-WARNING **: locale not supported by C library

The user id is correct, and the gnome running on solaris works fine. I believe 
this is related to the problem described in the previous mail.
