Hi,
I need to test one specific port on a serie of Ip addresses that I own, I thought about using nmap or telnet, but both return the same value, no matter if the port is open or filtered.
Anyone has an idea, before I start scripting to analyse the output of the command?
If you're using nagios for any monitoring, there's a nmap plugin in the contrib directory of the nagios-plugins package. It will notify you if the host displays any open ports not pre-defined as open for that host.
And there's a check_tcp plugin for the simpler single-port case. You can also use the plugins directly even if you're not using nagios. The nagios-plugins package is available from Dag's rpmforge repo.
