You would think a stereotypical Linux user would not mind getting his hands dirty in the command-line trying to make a program work. Well, either this user is not typical or that’s not true. The LogMeIn Hamagi VPN solution seems to have some cool features, but the Linux client was painful to figure out. Some documentation or instructions would be nice, but I think a nice basic user interface would also be helpful. Command-line is cool, but I just need to get connected, and I don’t want to learn yet another networking tool to get where I need to go.
If you are attempting Hamachi, this blog post is your lifesaver:
Eric Lefevre-Ardant on Java & Agile: How to use LogMeIn under Linux
Next task is finding the Linux client. They don’t have a production one, but they do have a beta version available. Check out their beta page: LogMeIn Labs & Betas. This part is awesome once you find it — choose your flavor, deb or rpm, they have it. The Deb worked great for me on Ubuntu x64 10.04.
After installing, it was like nothing happened. No new menu items show up in the menu. Well, don’t worry, it installs a service and a command line program. Here are the files shown in the package:
When the package installs, it starts the service. You can see it running here:
Now, you have it installed. You need to use the command-line program to connect. First, you simply need to connect to the LogMeIn server (everything goes through there server). Note that you don’t need a user name or any credentials for this part (that will come later). Here’s the command plain and simple:
sudo hamachi login
Now, if you have an account on LogMeIn, you need to “attach” to it. If you are connecting to someone else’s network, you can skip this step.
sudo hamachi attach <email_address>
As far as I can tell, the next command just sets a name for your client. This is the name that will appear in the administration pages online for LogMeIn Hamachi.
sudo hamachi set-nick <name>
In my case, I set my nickname to “stephen”:
Then, online it will show this name:
Now, the final step is to connect to the network. This is where it got really confusing for me. It was not the command or how to do anything, but the problem was just determining what network ID to use. So, let me walk you through how to figure out the ID.
The person with the account on LogMeIn who setup the network, will need to login and view the “My Networks” page. Then, click on the edit link next to the network:
Then, here’s where you see the network ID to use in the join command.
Once you know this ID, you can simply run the command:
sudo hamachi do-join "<network ID>"
It may ask you the password for the network. The LogMeIn account holder can optionally setup the password. If no password was setup, just hit enter, and it will proceed. Here’s what the configuration looks like when you setup a network:
Now, you should be connected. You should have a new network interface in your network settings:
If you need to connect to other machines in the Hamachi network by IP address, you will need the LogMeIn account holder to give you those IP addresses. You talk to other machines via the IP address for the Hamachi network not the local network.
All in all, once you get it setup, it seems to work well. I don’t like the fact that you have to run the program as administrator. For my other VPNs, I don’t need super user access to configure or connect. I also don’t like having an extra service running in the background. Why can’t it just use the Network Manager Applet like the other VPNs?
Now, I would be amiss if I didn’t mention the GUI. I found a Community Thread that points to a front-end called Haiguichi. It has a Deb package that you can install, and that part worked fine. It gives you a new menu item under Applications > Internet > Haiguichi. I couldn’t get it to configure though, and I finally figured out the command-line, so I left it alone.
