I just try to check if a port is available, or not, but the check always fails, while using telnet, I can open the same connection (tcp port 5001).
What plugin are you using?
I have tried with external IP address of the host, and also with localhost. Both works with telnet, but unavailable from RHQ.
It is not a standard port, and there's a propiertary service behind the port - but I just need to check if it's open, or not.
I wonder if the sender IP for your telnet experiments is different than for the agent, so that some firewall rules that check for sender + receiver (IP,port) may match for telnet, but not for rhq
Do you have a chance to trace both connection attempts (agent, telnet) with tcpdump and see how they differ?
