I am wondering is the port correctly setup in my Suse linux if it is showing this? I need to access port 30015 from another host, but at present it is able to ping the host but not able to connect to the port.
netstat screenshot you shared , it seems
Port 30015 is listening in TCP mode. Now to check the connectivity , you can use
telnet <hostname> 30015 or nc -v <hostname> 30015
For example , I am checking for Port 22
nc -v localhost 22 Connection to localhost 22 port [tcp/ssh] succeeded! SSH-2.0-OpenSSH_5.3
If you are getting "Connection refused" message , check for firewall on destination server.
You can use below command to check firewall rules
iptables -L -n (as root)
iptables is blocking the connection , disable
iptables using below command or add new rules to allow
service iptables stop ; chkconfig iptables off
Adding rules to allow SSH
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
