Hi all! This is my first message to the list. I've been browsing the archives, i've asked Mr. Google, but i cannot find an answer to my problem. But i'm sure i'm not the only one with this problem. Now here is what i'm struggling with: I've installed Nagios 3.0.6 on a FreeBSD Jail. Now, from this jail i cannot ping my hosts because of some sockets restriction of the Jail. I got the suggestion to install echoping instead, but i don't seem to get this working either. When i echoping my hosts, i get a connection denied error. I can ping my hosts from any other place on the internet (home, mobile phone, work office), but from the Jail i cannot. I cannot change the config of the Jail because it's a provider hosted system. So my questions are: - Am i the only one with this problem? - Does anybody have a good check-host-alive definition that works from the jail? - Is echoping supposed to work or not? - If nobody has a good check-host-alive definition, how can i switch this check off? I can check on other services to know if the server is up or not, but i don't want the "host down" status in my tactical overview. That's it so far. I'm sure for you people it's simple and it's been asked a zillion times before, but honestly, i cannot find the answers. Thanks in advance, Ton.
