Haguichi is a popular Hamachi (including Hamachi2) GUI for Gnome.
Haguichi 1.0.7 has been released, the big news being that it finally adds AppIndicator support so you don't need to tweak the notification area in Ubuntu 11.04 to get Hamachi to show up (but of course, the AppIndicator works in older Ubuntu versions too).
As usual, I've updated the Haguichi PPA (this is basically the official PPA) so you can easily stay up to date with new versions in Ubuntu 10.04, 10.10 and 11.04.
Please note that the Haguichi AppIndicator comes as a separate package!
Add the Haguichi PPA and install Haguichi using the commands below:
sudo add-apt-repository ppa:webupd8team/haguichi
sudo apt-get update
sudo apt-get install haguichi
To install the Haguichi AppIndicator, run the command below:
sudo apt-get install haguichi-appindicator
