26.11.2019 · With pysftp, I see how to set a timeout for any commands once you're already connected, but I don't see how to set a timeout for the connection itself. I feel like I'm missing something somewhere. Just to try it, I tried adding timeout=3 to the Connection method and got an error, and tried using cnopts.timeout=3 and that did

4.13.1 Using keepalives to prevent disconnection. If you find your sessions are closing unexpectedly (most often with ‘Connection reset by peer’) after they have been idle for a while, you might want to try using this option. Some network routers and firewalls need to keep track of all connections through them.

Sep 07, 2016 · In Paramiko-using code that does not call set_keepalive, I'd expect your situation to arise - the network connection drops but Paramiko can't tell and so is_active stays True. But if you were to use, say, my_transport.set_keepalive(60) it would trigger actual network packets every 60s which I'd assume would keep just about any network channel open.

There is no absolute answer here, as FTP protocol in itself does not include such a mechanism. There is however, FTP protocol commands with no real meanings on a given situation like "NOOP", "LIST" or "CWD" which can be used to keep the FTP connection alive.

I want to keep the connection alive while using the get() method. Any leads, much appreciated. Code snippet: `sftp_conn = pysftp.

The keepalive helps to maintain the transport layer persistent and prevents intermediate firewall to purge the SSH session, or the server etc.

To give you an example, the well known Filezilla is implementing such a mechanism (see in "Edit" -> "Settings" menu item, then in "Connection" -> "FTP" tab): Answer to edit: As said, only evolved ftp client would have such functionality. Default ftp client, Windows and Linux alike, are not able to apply such keep alive behavior.

06.03.2018 · 2. If sshd_config is configured with TCPKeepAlive=yes but with ClientAliveInterval=0 (i.e. only TCP level keep-alive packats from the server) then the connection dies after about 15 minutes because oddly the TC client is closing it: Code: Select all.

API¶. A friendly Python SFTP interface. class pysftp.Connection (host, username=None, private_key=None, password=None, port=22, private_key_pass=None, ciphers=None, log=False) ¶. Connects and logs into the specified hostname. Arguments that are not given are guessed from the environment.

This only creates the Transport object; it doesn't begin the SSH session yet. ... This can be useful to keep connections alive over a NAT, for example.
