First post here but hopefully someone can help with the issue i am having.
We have had a nagios box monitoring our SAN's for quite a few years, unfortunately the nagios box we used suffered a failure and we had to replace it.
We have rebuilt the box and everything is now working great, however, i have reinstalled the nagios plugin fore the DX80 and regenerated the public/secret key for the SAN and installed it into the user accounts on the SAN.
Now, nagios is coming back with 290 : Internal error occurred.[ssh return code = 255] for every check against the DX80.
HOWEVER, running the check manually on the nagios box to the SAN works perfectly fine and returns the correct information i expect, i can SSH to the SAN as the nagios user without having to enter a password, however i am still getting error 290
I have a suspicion that this could be because the SAN is expecting a different host ssh key and because of that, its refusing details, but i am not too great with linux and such.
Any help would be appreciated!
