Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

A service is running in my system (redhat linux) which opens the port 9000. When i do
# telnet localhost 9000 it says,

Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

But when i do the same with my network ip,
# telnet 172.21.198.62 9000

It says,

Trying 172.21.198.62...
telnet: connect to address 172.21.198.62: Connection refused
telnet: Unable to connect to remote host: Connection refused

Why is that ?

I've diabled the firewall using service iptables stop


Moreover this happens only for this port, telnet 172.21.198.62 22 works properly.
