In the last article, I introduced Hamachi, a free software to easily create a VPN. Hamachi works even when computers are behind a router, so you can easily use it between office, home and anywhere.
UltraVNC is another useful remote tool and it is open source. If you have use tools like PCAnywhere, UltraVNC is something like it. UltraVNC allows you to connect to and take control of a remote computer.
Used together with Hamachi, you can connect to a computer behind your office router without having to set up special port forwarding in the router. (In the UltraVNC website, there are some other solutions to accomplish the same thing. I have not tried them since Hamachi+UltraVNC works for me.)
The advantages of using UltraVNC with Hamachi are
- Encryption. Hamachi already encrypts all traffic by default. So UltraVNC traffic are encasulate within.
- Private IP. Connect with private IPs and not available on public IP network (for computers behind router).
Let’s take a quick look at how to use UltraVNC.
