No route to host

[rvaedex23]

I am trying to telnet IP 9200.
When the firewalld is turned on I get this error: telnet: connect to address 172.xx.xx.xx : No route to host

When the firewalld is turned off I get this error: telnet: connect to address 172.xx.xx.xx: Connection refused

I want to be able to telnet from a client to another server.

thanks

The no route to host message is probably caused by the firewall rules not allowing the port through so it falls through and uses the last rule which will reject the connection with an icmp message. The Connection refused error probably means that there is nothing listening on that port even if the rules let you get through.

I do have the port opened:

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State

It is only listening to port 9200 on localhost, not your lan interface.

How can I fix that. Thanks

[TrevorH]

Fix the application so that it listens on other than localhost.
