    If you want file management you can do this using SFTP that you get when you install openssh-server. You can also Web browse using the system if you setup an SSH tunnel or you can even install squid and set the pi as your web proxy in the system you are using's browser. You don't need VNC.

I'd post it again (Linux workstation/laptop to any ssh-server), but my laptop isn't powered on and I can't ssh into it right now.

    Hummmm ... but I have backups online somewhere.

    Code:
    #!/bin/bash
    
    PORT=64001   # ssh port, best not to use 22/tcp from the internet
    SSH_SRV=my-ssh-server.example.com   # could be an IP
    
    # Only start SOCKS proxy if necessary
    if  [ $(/bin/ps -eaf |/bin/grep ssh |/bin/grep -c $PORT ) = 0 ] ; then
       # Setup SOCKS proxy through home server
       echo "Starting ssh SOCKS Proxy"
       /usr/bin/ssh  -f -C -D $PORT  $SSH_SRV  -NT &
    fi 
    
    # Star private firejail with chromium, going through 
    # just setup SOCKS proxy
    sleep 3;
    echo "Starting Firejail chromium with private & proxy "
    export http_proxy="socks5://localhost:$PORT "; 
    /usr/bin/firejail  --private chromium-browser \
             --proxy-server="socks5://localhost:$PORT " &
    
    exit;
    I use firejail in a private mode. Chromium allows specifying the proxy-server on the command line. Firefox does not, so I use chromium for this purpose. Chromium runs on my local machine and all HTTP/HTTPS traffic is sent to $SSH_SRV before going to the final address. That address can be local, on the same LAN or on the internet.

    It is also possible to use X11 to run chromium on the remote system and have the window displayed on my workstation.
    Easy ...
    Code:
    $ ssh -X regulus /usr/bin/firejail  --private chromium-browser
    panic: permission denied
    
    goroutine 1 [running]:
    github.com/snapcore/snapd/snapdtool.ExecInSnapdOrCoreSnap()
       /build/snapd-xa84xt/snapd-2.51.1+20.04ubuntu2/_build/src/github.com/snapcore/snapd/snapdtool/tool_linux.go:205 +0x59e
    main.main()
       /build/snapd-xa84xt/snapd-2.51.1+20.04ubuntu2/_build/src/github.com/snapcore/snapd/cmd/snap/main.go:452 +0x39
    ... unless there is a snap package involved. snaps just want to get in the way. I think it is that chromium has their own sandbox which conflicts with firejail. Let's try that again, without firejail:
    Code:
    $ ssh -X regulus chromium-browser
    Yep. That worked, through running a full browser on a raspberry-pi won't set any speed records. Also, X11 forwarding doesn't do audio, but video is fast on most LANs.
