NIS warning or Error

[linux user <linuxteam@xxxxxxxxx>]

Hi,

I have already tried posting this before, and in
comp.os.linux.networking but have not yet had any responses.

I am getting lots of the following log messge on a slave nis Linux
server lately, the only thing that was changed was the implementing of
the passwd.adjunct.byname on the NIS master (runing solaris 9)

ypserv[11225]: refused connect from 10.8.208.85:34346 to procedure
ypproc_match (nis_domain,passwd.adjunct.byname;-1)

restarting the services such as ypservr, portmap did not reslove the
issue, checking the sevice using rpcinfo -u nisslave servicename does
not report any obvious problems from any clients involved.

the funny thing the moment i enable debugging on the ypserv daemon,
the refusal log message dissapear, my thoughts was if this was an
error message why can't i correlate it to an error message on the
clients, I can not see RPC time outs, or a lose of functionality on
the client side at all so far.

today the problem disappeared mostly, checking the source code of the
ypserv for the refusal message shows its a warning
<code>
if (debug_flag)
    {
      log_msg ("%sconnect from %s", status ? "" : "refused ",
               inet_ntoa (sin->sin_addr));
    }
  else
    {
      if (status < 1 && ((sin->sin_addr.s_addr != oldaddr)
                         || (status != oldstatus)))
        syslog (LOG_WARNING,
                "refused connect from %s:%d to procedure %s (%s,%s;%d)\n",
                inet_ntoa (sin->sin_addr), ntohs (sin->sin_port),
                ypproc_name (rqstp->rq_proc),
                domain ? domain : "", map ? map : "", status);
    }
</code>

how would one go about troubleshooting such an issue, and resolving
it, the main subsystme involved i guess are the portmapper, ypserv,
and nscd on the server side, and ypbind, and portmapper, and nscd on
the client side, the clients, and servers tried so far are redhat
linux 8.0, and RHEL 3.0 all have same response.

Is that a warning, that i should be troubled with?

regards

Walid,
