I am using Nagios 3rc1 on Ubuntu 7.10. I'm a fairly novice user but have found the product easy to use and configure.
I have one problem with check_tcp that I have been unable to resolve. When I run the plugin from the command line it works ok:
root@xxxxx:/usr/local/nagios/libexec# ./check_tcp -H xxxxxxxx -p 3389
TCP OK - 0.014 second response time on port 3389|time=0.013579s;;;0.000000;10.000000
However, when I try to use the check_tcp for the hosts check_command the plugin returns the following error:
check_tcp: Port must be a positive integer
The paramters used are exactly the same as those on the command line:
Is it possible to use this plugin for a hosts check_command?
