Troubleshoot SSH (-IX)

About this task

Use the SSH command on the job execution host to connect it securely with the job submission host.

If the host fails to connect, you can perform the following steps to troubleshoot.

Procedure

Check the SSH version on both hosts.
If the hosts have different SSH versions, a message displays identifying a protocol version mismatch.
Check that public and private key pairs are correctly configured.
Check the domain name.
$ ssh –f –L 6000:localhost:6000 domain_name.example.com date

$ ssh –f –L 6000:localhost:6000 domain_name date

If these commands return errors, troubleshoot the domain name with the error information returned.

Results

The execution host should connect without passwords and pass phrases.

Example

$ ssh sahpia03
$ ssh sahpia03.example.com
