can't get Pure-ftp to work from one location
Posted on 2011-03-18
I just setup a pureftp server on a RHEL6 box and it works great. I've tested it from the LAN and from the WAN and it's okay. However, we have a site-to-site connection and it won't work from there.
It works from the WAN so it's not a question of the firewall rules or SELinux
if you use telnet on port 21 it actually establishes the connection but then closes it
The log on the ftp server shows:
16:08:47ftpserver pure-ftpd: (?@server.domain.com) [INFO] New connection from server.domain.com
16:08:53 ftpserver pure-ftpd: (?@server.domain.com) [INFO] Logout.
The telnet from a linux box in this location shows:
[root@test ~]# telnet 220.127.116.11 21
Connected to ftp.domain.com (18.104.22.168).
Escape character is '^]'.
Connection closed by foreign host.
So it's not the firewalls because you can see that the connection gets established...but then it gets closed by the server it would seem. But only from this one location. Every other location is fine and I can get in with an ftp client and upload and download files. With an ftp client in that location it just says 'Could not connect to server'....
Anyone have any ideas....I'm stumped.
