Run SSH Command Operator Fails

[Legacy User]

I have to trigger the script placed on the Linux Server. On connecting manually via Putty, it is working fine. But when I run it using the operator, it gots failed and the Reason contains our command that I provided using Pre-Execution of the operator.

Kindly help me out if anyone have some information regarding this issue.

If you remove the pre-execution code, does it work?  If the pre-execution code is returning an error, then it isn't getting to the script yet and you will need to figure out what is wrong with the pre-execution code.  You can post the error here which might clarify what the problem is.

Hello Andrew Thompson

The pre-execution code is working fine. The command that I run using the "Run SSH Command" operator, gets executed on the target Server. But the output of the script is not coming in the SSHCommandsOutput[] variable, which is there when I run the same command using putty. I am facing this type of problem on some flavours of Unix. On some servers it is working fine, but for others it is not working as it should do. Kindly let me know if I missed some settings or something else.

Thanks in advance.

Without the actual error message it makes it difficult to know what the problem might be.  If this command works on certain Unix machines and not on others, it might be an SSH config issues.  You might compare the sshd.conf file on your Unix systems to see what might be different.  I do know that the blowfish cipher is necessary for PAM to communicate via SSH.  Here is a knowledge doc on that:
