Today, I was trying to configure nagios to monitor an asterisk setup. I installed the nagios-plugins-check_sip plugin available for CentOS. I also had check_asterisk downloaded from here just to try out both. Now, check_asterisk and check_sip are perl scipts which can be used to monitor an asterisk setup. When run through the command line, they seem to work fine, i.e: given that asterisk or any other sip server is listening and your command is correct, you should get output similar to this: ;SIP/2.0 200 OK, 0.000585 seconds response time, cnt=1 Although, that's exactly what I got, it didn't work the same way through nagios, I was getting the following as the output from the plugin. (Service check did not exit properly) After enabling debug info for nagios, I found this in the logs, HOST: remotehost, SERVICE: Asterisk, CHECK TYPE: Active, OPTIONS: 1, SCHEDULED: Yes, RESCHEDULE: Yes, EXITED OK: No, RETURN CODE: 3, OUTPUT: **ePN failed to compile /usr/lib64/nagios/plugins/chec...

By default, CouchDb is configured to be access only from a local port, i.e: you can connect to a couchdb instance as long as it is on the same host. Also, it is necessary that the HTTP request be made using the loopback IP address (127.0.0.1). In case you want to be able to access a couchdb instance from an external machine, you need to make some changes to the couchdb configuration. Note that you would need to have superuser access in order to make changes to these files. Usually couchdb will have two configuration (ini) files in /etc/couchdb depending on your installation. Both these files (default.ini and local.ini) can be used to enable remote hosts to access couchdb. The configuration required for this is: [httpd] port = 5984 bind_address = 0.0.0.0 By default the configuration would be: [httpd] port = 5984 bind_address = 127.0.0.1 This means that the Http server is bound only to the loopback IP address, which is why we change it to 0.0.0.0 to make it bind to any IP address.
