[Nagios-users] Hosts with one service in error state never get checked - bug?
Hi, I've got a few hosts with just one service each. If the service goes into a non-OK state, then later the host goes down, when it comes back up Nagios never checks the host if the service is still not OK. The host still looks like it's down as far as Nagios is concerned. Is this a bug?

Re: [Nagios-users] check_ssh causing log errors on remote servers?

This is because check_ssh doesn't actually do any negotiation with the sshd at the other end. It just connects, gets the version string sent by sshd, and disconnects. Your sshd is moaning that the client disconnected before entering into an ssh dialogue. The broader point, I suppose, is that check_ssh only checks that sshd returns a valid version string. It doesn't check if, for example, sshd is misconfigured in such a way as will prevent authentication. - Ian -- Ian Chard, Senior Unix and Network Admin | E: [EMAIL PROTECTED] Systems and Electronic Resources Service | T: 80587 / (01865) 280587 Oxford University Library Services| F: (01865) 242287 - Take Surveys.

[Nagios-users] Non-US date formats in CGIs
Hi, Is there any way to coax the CGIs, specifically when you set downtimes, so that they use the British date format (DD/MM/)? - Ian -- Ian Chard, Unix Network Administrator | E: [EMAIL PROTECTED] Systems and Electronic Resources Service | T: 80587 / (01865) 280587 Oxford University Library Services| F: (01865) 242287 --- This SF.net email is sponsored by: Splunk Inc.

Check nagios.cfg for the line: date_format=euro Hmm, at the moment I have date_format=iso8601, but I still get dates of the form 11/23/2005 when I go to set downtime. AIUI iso8601 should give -MM-DD format. - Ian -- Ian Chard, Unix Network Administrator | E: [EMAIL PROTECTED] Systems and Electronic Resources Service | T: 80587 / (01865) 280587 Oxford University Library Services| F: (01865) 242287 --- This SF.net email is sponsored by: Splunk Inc.
