ftp not allowing connections on port 21

I'm not sure if this has anything to do with WHM or Cpanel but I'd like to use it before editing the files manually to keep integretiy on the system.

Right now I cannot login to ftp on port 21 but I can login to ftp using the secure port 22 with WinSCP. What could be the cause of this? In WHM's FTP controls I switched between proftp and pure-ftp. Neither would allow me to login on port 21.

What is most interesting is it would appear that port 21 is blocked all together. I always get a time out error. It is a dedicated server so I have full control over the server settings. There is not a firewall at the datacenter blocking my port 21.

Any ideas?

Thanks for the help.

 

Thanks for the reply. I'm calling my hosting company to find out about a possible firewall.

I did a "nmap localhost" and ports 21,22 are both open. I can't understand why I can ftp securely on 22 but not non-secure on port 21.

My proftpd.conf file is very similar with yours and has all the <virtual host> listed as well as the correct /auth/passwd.vhost file which seems to have the right values.

Everytime I try to connect I get a timeout like the server is blocking the port all together.

I should add the following. When I connect on 22 I'm using WinSCP. If I use a program like WS_FTP Pro I cannot connect using ftp.mydomain.com on either ports 21 or ports 22 passive mode or non-passive mode.

Even more interesting. If I ping ftp.mydomain.com I get nothing back. I also tested the ping for other servers I have and it worked for them. So maybe this is another issue?
