I'm able to remote login the target host with ssh. But when I execute a command through
pdsh, it fails with
connection refused. Both systems are sles11.
I found a description of the error on this page as follows.
pdsh@local_hostname: target_hostname:connect: Connection refused
The target system is unreachable, or the r services may be disabled for this system.
Check the r services and whether the target system is up and connected.
In my case, the target system is up so the cause should be the disabled r services.
So what are
r services and how could I enable it?
