FTP without timeout?

[Chris]

How do I setup an FTP connection without timeout using ftplib.FTP?

I've tried
ftp = ftplib.FTP('server')
ftp.login('user', 'xxx')
ftp.sock.settimeout(None)
or
ftp.sock.settimeout(3600)
or
ftp.sock.setblocking(True)
but it always timeout after 10 minutes of inactivity.
The server allows idle up to 240 minutes before disconnecting.

Please help! Thanks in advance.

Try putting

import socket
socket.setdefaulttimeout(240*60)

at the start of your code to see whether this makes a difference. This
ensures that the socket timeout is established before a connection is
made to the remote endpoint.

Though frankly, from the documentation, since there doesn't appear to be
a default timeont on sockets, I'm not sure where this bizarre ten minute
timeout is coming from. The string "time" doesn't appear at all in the
ftplib source, so I'm somewhat stumped.

Are you sure the server doesn't require some sort of keepalive from the
client?

An intermediate firewall could also need a keepalive - it's not uncommon for
them to kill idle connections after a few minutes.
