Check_Vnc

Documentation Tests VNC on a remote machine, including logging in and taking a screen shot. It accepts a standard vnc credential file with which to authenticate. The screenshot is a more realistic test that just a port test, and is done at minimum display quality leading it to be surprisingly fast test (~0.3 seconds). The plugin relies on the vncsnapshot program. On Gentoo: "emerge vncsnapshot" On Debian: "apt-get install vncsnapshot" or get vncsnapshot from http://vncsnapshot.sourceforge.net here Usage ./check_vnc -H somemachine --passwd-file credentialsfile OK: vnc logged in and image obtained successfully ./check_vnc -H Kosh --passwd-file vncpass --verbose OK: vnc logged in and image obtained successfully. VNC server supports protocol version 3.8 (viewer 3.3) ./check_vnc -H Starfury -f vncpass --timing OK: vnc logged in and image obtained successfully. Test completed in 0.307 seconds Options ./check_vnc --help usage: check_vnc options options: -h, --help show this help message and exit -H SERVER, --server=SERVER The Hostname or IP Address of the VNC server -f PASSWDFILE, --passwd-file=PASSWDFILE The VNC password file to use. You can generate this using 'vncpasswd ' on the command line -t TIMEOUT, --timeout=TIMEOUT Sets a timeout after which the the plugin will self 1. Defaults to 10 seconds. -T, --timing Enable timer output -v, --verbose Verbose mode. Good for testing plugin. By default only one result line is printed as per Nagios standards -V, --version Print version number and exit Limitation Cannot currently test a vnc server on a non-standard port due to an underlying restriction of the vncsnapshot program which seems to be common to several vnc based programs. I have made a feature request for this, but until it is implemented, it's not possible to re-write this plugin to have a --port switch.
