check by SSH no error message

[CFT6Server]

I am setting up another box with check by SSH. This worked on other boxes but not this redhat box and I am not sure why.
I have confirmed that ssh with the keys worked by doing ssh nagos@remoteip, this connects no problem. When testing the nagios checks, it is coming back with a blank error message. Any ideas? Did I miss something?

Code: Select all

# ./check_by_ssh -H remote -C uptime
Remote command execution failed:

When you ssh into the machine, are there any 'pre' text type things that show up in the terminal? In the past, I've had to add -E 1 (IIRC) to skip the initial terminal prompt.

Code: Select all

     -S, --skip-stdout[=n]
        Ignore all or (if specified) first n lines on STDOUT [optional]
     -E, --skip-stderr[=n]
        Ignore all or (if specified) first n lines on STDERR [optional]

If that doesn't help, could you show us the full output when running ssh user@host, and also running check_by_ssh with -v? This should provide a bit more information.

Perfect. Thanks! -E did the trick as there was a banner message that caused it.

That's great to hear, are we okay to lock this and mark it as resolved or do you have any other related questions?


Thank you

That's it. Thanks.
