I have a FTP server (vsftpd) setuped on a Linux box (Ubuntu server). When I try to connect with a computer on the same network everything works fine as expected.
But as soon the IP is external it won't connect..
I first assumed the port was blocked, but then:
localserver:$ sudo tail -f /var/log/vsftpd.log
Wed Jan 13 14:21:17 2010 [pid 2407] CONNECT: Client "xxx.xxx.107.4"
remotemachine:$ netcat svn-motion.no-ip.biz 21
220 FTP Server
And it hangs there. Do any ports other than 21 need to be open?
sftp does not use multiple connection, it only use 21 and thus is passive by default. – h3. – 2010-01-13T19:35:45.457
if you are using SFTP then the default port would probably be 22 – quickcel – 2010-01-13T19:40:46.537
Oh, right.. when using ftp only I get "Unknown server error" – h3. – 2010-01-13T19:43:51.523
When using the IP directly it works .. – h3. – 2010-01-13T20:18:36.337
