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

Hi criws93! MySQL by default binds to the localhost port only. If you run the following command
netstat -an | grep 3306
You should see something like 127.0.0.1:3306
This can be changed by modifying the config file for MySQL:
sudo nano /etc/my.cnf
You will want to change the IP at the word ‘bind’ to ‘bind=0.0.0.0’
Note: This can cause security problems! Please be aware!
Now you can restart MySQL:
sudo service mysql restart
And then run the following command again:
netstat -an | grep 3306
And you should see something like 0.0.0.0:3306
If you have any further questions, let me know!
