Question

EnterpriseDT.Net.Ssh.Routrek.SSHC.SSHException: Format of SSH version is invalid

Periodically I get this exception in production. Can some one tell me where this is thrown from and why? I'm assuming it's just random attempts to access my FTP site, since no customers have complained, but I just want to make sure.

Thanks

Answer 1

If you examine the server log file, it should give more details. Please post the relevant snippet.

Answer 2

This is all that is in the logs, then the session is closed

INFO SFTPConnection [Session.2390:Default Site:user?] Client version = 'GET / HTTP/1.0'
ERROR [Session.2390:Default Site:user?] Receive error: SSHException: Format of SSH version is invalid

.

Answer 3

That is an HTTP request on an SFTP connection. No wonder it fails!
