check_imap connection refused

[tgfde]

Hi,

After configuring NTP on this linux (SUSE 11 - nagios client) box, I get a message from Nagios complaining about a connection being refused when checking IMAP on the client.

Has anyone seen this? It seems like IMAP is working but I think Nagios could no longer check the status of it after configuring this client to sync its time to a NTP server.

Thanks.

Does the problem persist if you disable NTP again?

[tgfde]

Yes, it does.
I don't think it's related but it's the latest config change on this client.

Thanks.

[agriffin]

Well even if it's not related we should at least rule it out first, especially since everything was working before (right?). You could try syncing your XI server with the same NTP server to make sure that time skew is not the problem.

I have another Linux client and just sync the time and the IMAP service is ok.

Thanks.

Below is the full check_imap command:

$USER1$/check_imap -H $HOSTADDRESS$ $ARG1$

Thanks.

Well, if Nagios says the connection was refused it could be a firewall issue. Is the iptables service running or are you behind any other firewalls?

[tgfde]

Iptables service is not running and I'm not behind a firewall.

Thanks.

What happens if you run "check_imap" command in terminal? Can you post the output?

Go to your "libexec" directory, for example:

# cd /usr/local/nagios/libexec

Then run:

# ./check_imap -H XX.XXX.XX.XXX -p 143

where XX.XXX.XX.XXX is your email server IP address

I get the same result, "connection refused".

Thanks.
