In Windows, why does SSH Secure Shell keep warning me about the SSH1 protocol?

SSH Communications Security's SSH Secure Shell is an SSH2 client that can connect to SSH1 servers. Since SSH1 is not as secure as SSH2, the program displays a warning when it detects an SSH1 server. When the warning comes up and asks you whether you want to accept this connection, click Yes to connect.

To change the security level of the program to either allow SSH1 connections without displaying the warning, or deny SSH1 connections:

1. From the Edit menu, select Settings... .
   
   
2. If it's not open already, in the tree on the left side of the Settings dialog box, click to open the Global Settings category.
   
   
3. Click Security. In the "SSH1 Connections" section, select Allow or Deny.
   
   
4. Click OK. From the File menu, select Save to save your new setting.
