iptables and other useful port commands

So we had the server up and running but could only get CPRS running by ssh tunnel at first. We had to open a port on the Linux server as well. Congruency of port numbers for both client and server are necessary. Something like 9330 which should be present in the CPRS P= parameter list and in the xinetd listening port. We used a TCP, not a UDP port so step 2 below is not necessary if you are using TCP only. The following commands taken from this page: http://blog.eukhost.com/webhosting/how-to-open-port-on-server where needed to open our port on the Fedora 9 server so that we could use CPRS from any client without the tunnel:
you can verify the port with
netstat -nap | grep :
1.you can open TCp port with
iptables -A INPUT -p tcp –dport 9330 -j ACCEPT
2. You can open UDP port with
iptables -A INPUT -p udp –sport -j ACCEPT
after that
3. service iptables save
and for flushhing iptables us
4. iptables -F
