IRC problems on Amazon Web Service

[Robert'); DROP TABLE *;]

I'm trying to set up znc (to maintain IRC connections for me) on a micro instance from AWS, and I'm running into weird problems. I've opened the port in question (7777) in their security settings, and can't find any other security that might get in the way, but something is still going wrong.

Specifically, trying to connect from my local machine gives "Connection timed out." (As opposed to picking a closed port, which returns "Connection refused.") Running irssi through SSH on the server itself and connecting to localhost allows a connection, but that connection immediately disappears. The machine is connecting to the external network with no problem, and I can SSH in, so I'm lost for why I can't get in via my IRC client. (Xchat for Windows) The server's running Ubuntu Server, and AFAIK has no special firewall or other software that might interfere.

Does anyone have any clue what's happening?

Try running netcat instead of your IRC program, to make sure there aren't any software problems... on the server run

Code: Select all

nc -l 7777

and on your local machine run

Code: Select all

nc servername 7777

If it works, you should be able to type in one and hit enter, and the words will appear in the other.

If that works, something's wrong with the configuration of your server program... if that doesn't work, something's wrong with the server settings. Firstly, you are connecting to the server's external IP, right? Not some internal AWS-network IP? IIRC from when I was running an AWS server for a while, external IPs had to be allocated and set up separately, and then assigned to an instance... if you don't do that, then the instance won't be visible from outside the network. I imagine if you can SSH in then you have this sorted, but maybe they have something to handle that, I can't remember.

IIRC when I set mine up, the only thing I had to do was to enter the port number and hit allow in the security settings when setting up the instance (though I seem to remember being unable to change it afterwards without tearing down the instance and creating a new one). After that, everything worked.

It works if I use PuTTy in telnet mode to make the connection from my local machine, which I assume is the same thing. What am I supposed to be looking for in the config? (The program in question is ZNC, if that helps.)
