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

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.

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.

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

Some network routers and firewalls need to keep track of all connections through them.

Connection(host=ipHost, username=usernameLogin, password=passwordLogin) #set keepalive to prevent socket closed / connection dropped error srv.

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.

Jul 05, 2016 · Now, be default pysftp will verify the host. See pysftp.CnOpts.hostkeys. added pysftp.Connection.remote_server_key - used to retrieve the remote hosts server key. fixed an unwanted logging side-effect, after you set logging, it would remain, even if you closed the .Connection and couldn’t be changed to something else.
