Looks like a server-side problem. Please contact your server administrator.

When using the WinsCP, I couldn't connect the server. However, both computers were online and could ping through. I thought it was the problem of port 22. One of my server is Windows 2003, the other server is Red hat linux 9.0

Do you have a question?
