Hello,
I installed Ubuntu & Nagios on an old dell laptop to get familiar with it. Likewise, afterwards I installed the NSClient++ on my Vista desktop.
At first, it appeared to be working correct, but shortly after it has been giving me the following error. So it appears in the Nagios that the system is offline / down, but it's not.
CRITICAL - Socket timeout after 10 seconds
I'm rechecking the config files now and searching for the answer, but thought I'd just throw it out there if anyone could point me in the right direction. It worked initially, but seems something could be blocking it now. I've ruled out the Nortons Internet Security, as the client is "approved". Just doesn't add up--why did it initially work, now it's timing out?
