I am initiating file transfer using tcp on openfire server. But I am not able to open the port number 7777, from which I need to send files. I changed the security setting in the admin console panel of the aws. But still when I tried to send the files I am getting the error.

I tried to change the custom TCP rules, by opening only the 7777 port. But still I am not able to resolve it. Kindly help.

  • Is your FTP server actually listening on 7777? – Chopper3 Jul 04 '11 at 08:29

    Well did you specifically change your ftp server config to listen on 7777? they dont just listen to every port for the hell of it - in fact port 7777 is usually used by a piece of malware/virus, certainly isn't a recommended port of ftp traffic. – Chopper3 Jul 04 '11 at 09:14

    A quick test would be `netstat -an|grep 7777`, which doesn't need privilege to run. Let us know the output. – MadHatter Jul 04 '11 at 09:20

It is possible that your AMI has a firewall enabled that is blocking port 7777. Ubuntu usually uses ufw to control it's firewall.

run 

sudo ufw status

If it reports 

Status: inactive

then your problem lies elsewhere.

If it reports

Status: active

followed by a list of rules then you probably need to add a rule to allow access on port 7777

sudo ufw allow 7777

  • @lain: it was inactive first then I enabled it i got the msg saying"Rules updated" but I tried sudo ufw allow 777 but still the status is inactive, what will be the problem I have updated the security group to accept all TCP and UDP rules – Jeevan Dongre Jul 04 '11 at 10:41
  • @JeevanDongre: If the firewall was inactive (like I said) your problem lies elsewhere. – user9517 Jul 04 '11 at 13:53
  • @lian: let me brief u about the application which I am developing I have installed open fire xmpp chat server in the server and I am trying to initiate the p2p, that means sending files from one mobile to another mobile via port 7777, which is a default port in openfire server, but I am not able to open that particular port. Thanks a lot for guiding me :) – Jeevan Dongre Jul 05 '11 at 04:11
