Tengo dos servidores El programa en el primero necesita comunicarse con el segundo en el puerto 2194.
Sé que no funciona, porque cuando lo hago:
root@server1 [~]# telnet myserver2.com 2194
Trying 123.123.123.98...
telnet: connect to address 123.123.123.98: Connection timed out
telnet: Unable to connect to remote host: Connection timed out
server1# iptables -L -n
