--------------------------------------------------------------
Also, in SftpClientFactory.java, I hightly recommend changing the second call
of {{session.setTimeout(timeout)}} (after the connection is made) to
{{session.setServerAliveInterval(timeout)}} in . The second method sets the
timeout, too, but also sends keep alives to the server to keep the connection
alive. We need this in our environment for long-running jobs.

> [SFTP] Support connect-timeouts for SFTP-connections
> ----------------------------------------------------
>
> Key: VFS-533
> URL: https://issues.apache.org/jira/browse/VFS-533
> Project: Commons VFS
> Issue Type: Improvement
> Affects Versions: 2.0, 2.1
> Reporter: Christian Ciach
> Priority: Minor
> Attachments: sftpConnectTimeout.patch
>
>
> In contrast to other types of FTP filesystems, there is currently no way to
> have different connection- and socket-timeouts. This is because the
> Jsch-Session only accepts one timeout property which is used for both
> purposes. Because of this, a SftpFileSystemConfigBuilder also only provides
> one method called setTimeout(). The SftpClientFactory then applies this value
> to the Jsch Session before the connection is made.
> Looking at the implementation of a Jsch Session, it becomes clear the the
> timeout value is used as a connection timeout if it is set before the call to
> the connect-method. After the connection is established, one can call
> setTimeout() again to override the socket timeout.
> Currently VFS has no interface to support this behaviour, so I made a patch
> to support this.
