I'm running WinSCP 5.1.4 (build 3020), and it doesn't matter how I connect to this server: scripted, com/.net library, manually, I always get this.
I saved a log, and this seems to be the relevent portion:
. 2013-04-02 10:49:37.082 Disconnection message text: Unsupported request (firstname.lastname@example.org).
. 2013-04-02 10:49:37.082 Selecting events 0 for socket 764
. 2013-04-02 10:49:37.082 Server sent disconnect message
. 2013-04-02 10:49:37.082 type 7 (service not available):
. 2013-04-02 10:49:37.082 "Unsupported request (email@example.com)."
* 2013-04-02 10:49:37.121 (EFatal) Server sent disconnect message
* 2013-04-02 10:49:37.121 type 7 (service not available):
* 2013-04-02 10:49:37.121 "Unsupported request (firstname.lastname@example.org)."
* 2013-04-02 10:49:37.121 Authentication log (see session log for details):
From my understanding email@example.com is a special channel type that was created by the putty developer(s) and most servers, when they fail to recognize this simply ignore it. In this case, I'm immediately disconnected.
Is there a way to prevent WinSCP from requesting this channel? Nothing I have tried so far has made any difference.
Thank you very much
