Hello,
I'm having trouble connecting to a remote MS sql server (2008) through the ssh.net library.
I can create the ssh tunnel to the sql server, and test ok but when I try to connect to the db from my winform application I get this error:
"A connection was successfully established with the server, but then an error occurred during the pre-login handshake"
However if i use putty to establish the ssh tunnel it works fine!?
Any thoughts and help would be greatly appretiated since this is the last piece in my puzzle :)
Best Regards
Janne
