Looking for a tutorial

Posted in Linux, ubuntu by microwavebiscuit on September 5, 2007

I would really like to be able to remotely access my computer when traveling however I’m very concerned about opening up my PC for attack. What I’d really like to be able to do is use VNC/SSH to get full access to my PC’s resources from a Windows laptop when on the road. I’ve read a few things here and there but nothing that seems to be a complete guide to both setting up remote access and securing it completely.

    I am not sure on a good how to, but I do recommend using ‘knockd’ with whatever setup you use. It opens ports based on a knock sequence on certain ports, it can also close ports if it detects a port scan.

    I’ve written this on tunneling vnc over ssh:

    To tighten down the ssh port you could add:
    AllowUsers to your /etc/ssh/sshd_config file to only allow connections from your account.

    You could also limit connections to specific IP addresses, if you knew what those were.. but that gets tricky traveling. Let me know if you need/want more. I’m sure I can get you locked down enough..

    It’s pretty straightforward, really.

    Setup:
    * Make sure that all the users on your computer have secure passwords (even better, use SSH keys rather than passwords)
    * Install ssh_server
    * Make sure that port 22/TCP is forwarded in, from your router.
    * Set up some kind of dyndns, so you know your home IP address.
    * Turn on “Remote Administration”, and set a password for it, rather than requesting permission.

    On the road:
    * Use putty to ssh into home, before connecting go to port forwards, and add a local forward from 5901 to 127.0.0.1:5900
    * Then connect
    * Then you can use a VNC client to connect to “localhost:1”
