Here are some free SSH clients to use on your VPS:
1. Putty - the original SSH client and server. It is basically a no-frills program. Although, you can use addons to enhance it.
2. MobaXterm - our favorite and highly recommended SSH client! It has:
A. Built-in file editor (or use your own).
B. Built-in SFTP client. You can view the files on the server. If you right-click you can choose to edit the file in the editor of your choice!
C. Macros to record settings if you have to type many steps to do something. The next time you need it just run the macro!
D. And many more features!
3. Bitvise SSH Client
A. Similar to MobaXterm with some different features!
