Hi Moon,

Have you configured " NIS " or " NIS +"

If you have configured Naming server then
you need to check with the HOST maps.

Hi,

Seems to be a name resolution issue to me.

Try reverse lookup on those IP addresses, i.e,

# nslookup 192.168.11.110
# nslookup 200.100.100.100

What is the o/p of these commands? You would be able to figure out what's happening by these outputs.

Those ip addresss are not registerd in /etc/hosts file.

$nslookup 192.168.11.110
Using /etc/hosts on: erpDB

looking up FILES
*** No hostname information is available for "192.168.11.110"

Hi Moon,

The IP addr 192.168.11.110 will be not reg-
-stered, thiw will be the private IP, required for HEARDBEAT. Hence it will be
not regested. Can u tell me weather u have
NIS or not in ur domain.

Hi,

Can you provide "netstat -in" and "lanscan" outputs.

I think you would need to make an entry in /etc/hosts file.

Also, i don't think these errors has anything to do with MC/SG. These are sendmail messages.
