You want to connect to your server on campus using any SFTP client but you can't do it without VPN.
Use a SSH tunnel by connecting to UCONN SSH Gateway (ssh.uconn.edu) creating a tunnel to your server.
This can be done in two steps:
1- Create the tunnel
2- Use your favorite SFTP client (FileZilla or WinSCP) to connect to your server through the tunnel:
port: Whichever port you choose (in this tutorial we chose 2222 as an example)
username: the username on your server
password: your password
SSH Tunneling in Windows:
SSH Tunneling in Linux:
1- Create the tunnel using this command:
ssh -L 2222:[your server ip address]:22 [netid]@ssh.uconn.edu
2- Connect to your server using your favorite SFTP client or using SCP command but instead of using your server's IP address use "localhost" and port number "2222".
