Most of the times when I try to FTP to my VPS the log looks something like this:
27/06/2011 22:08:06 Stat> Connected. 27/06/2011 22:08:06 Recv> 220 Microsoft FTP Service 27/06/2011 22:08:06 Sent> USER myuser 27/06/2011 22:08:06 Recv> 331 Password required for myuser. 27/06/2011 22:08:06 Sent> PASS ******** 27/06/2011 22:08:06 Recv> 230 User logged in. 27/06/2011 22:08:06 Sent> FEAT 27/06/2011 22:08:07 Recv> 211-Extended features supported: 27/06/2011 22:08:26 Stat> Disconnected.
The connection is stuck on the line before the last one for half a minute and then disconnects.
Sometimes it succeeds in completing the login - in these cases right after the "Extended features supported" line indeed appears a feature list. But most of the time it simply gets stuck on that line (and sometimes 2-3 features appear and then it's stuck).
I tried various software, but the problem seems consistent.
Is there a way to workaround this?
How can I diagnose it?
What would be a probable cause?
