"refused connect from" -- messages in the log for NIS clients.

[GnanaShekar]

Hi,

We have recently added AIX servers as clients to the NIS hosted on Linux RHEL AS3 server.
I am seeing the following messages in the logs:


Mar 15 15:37:22 bangapps ypserv[869]: refused connect from 172.22.43.41:34216 to procedure ypproc_match (bangnis1,hosts.byname;-4)

The IP addresses listed in the logs are that of AIX servers. Please suggest.

Thanks & Regards,

do you have other NIS clients and they work OK?

Please try changing the ypserv.conf file.
Modify the "security" entry field (set to "port" by default) and replace it with "none"
