Port 21 will not open. status is closed. forward port 21 to new domains.
- by Bob Swaggerty
I am having a problem opening port 21 on my Linux Ubuntu server. No matter what i do, i can not get my status to change from closed to open. Here is a recent iptables command i used and the result
iptables -A INPUT -p tcp -m tcp --dport 21 -j ACCEPT
nmap -p21-22,25,80,443 CCR1
Starting Nmap 4.53 ( http://insecure.org ) at 2012-06-19 03:13 CDT
Interesting ports on CCR1.chennaichristianradio.com (5.10.69.98):
PORT STATE SERVICE
21/tcp closed ftp
22/tcp open ssh
25/tcp closed smtp
80/tcp open http
443/tcp closed https
I also used commands from the advise from this forum
http://www.cyberciti.biz/faq/iptables-open-ftp-port-21/
I need to open this for FTP access to the server, and ultimately I need to forward port 21 to 2 domains i am setting up. Thank you for any assistance you can provide
