Can't connect to TCP or UDP ports
Hi guys, I just made a droplet where I’m running Apache and SQL servers rightly. But I’m trying to catch some information through the network ports, for this I’m trying sending packets with PacketSender or some cellphone apps… however I can’t connect to the ports. I already used:
iptables -I INPUT -p tcp –dport #### –syn -j ACCEPT
or for UDP:
iptables -I INPUT -p udp –dport #### -j ACCEPT
But still is not working. Using nestat -a I expected to see a complete list of the listening or inactive ports just as in Windows, but it only lists the already-in-use ports…
I would appreciate a lot if you can answer me as soon as possible.
Have a nice day
