UNIX (REXEC) connection error:Failed to connect to server ErrorCode: 4000 -
Description
I am getting the following error when trying to connect to do OS monitoring.
UNIX (REXEC) connection error:Failed to connect to server
ErrorCode: 4000
Reason : rexecd: Couldn't look up address for your host -
Cause
The rexecd cannot resolve the hostname of the client machine that is connecting.
-
Resolution
Check to make sure you can ping both the unqualified and fully qualified hostname of the client machine from the server machine. If it is an intermittant issue, there may be problems with the DNS server.
A workaround is to add the hostname of the client machine to the /etc/hosts file on the server.
