Hamachi

Hamachi is a proprietary (closed source) commercial VPN software. With Hamachi you can organize two or more computers with an Internet connection into their own virtual network for direct secure communication.

Installation

Best way to install hamachi2 is to download the .deb package from the official source and then installing it (with sudo dpkg -i pakcage.deb && apt-get install -f), hamachi settings are available via command line. Look at the bottom of the page for GUI. Version 2 of the Linux Hamachi client exists and is currently in beta. It is available from the labs page on the Hamachi website.

Configuration

Set Up Tun

Being as section above can only be applied for init.scripts, in order to install the module, as root run:

# modprobe tun

Then add tun to the list of modules by using your favorite text editor and Create

/etc/modules-load.d/tun.conf 

#Load tun module at boot.
tun

Hamachi 2 (beta)

Hamachi 2 is configured in /var/lib/logmein-hamachi/h2-engine-override.cfg (create that file if it doesn't exist). Unfortunately, it isn't easy to find a comprehensive list of possible configuration options, so here are a few that you can use.

Using the hamachi command line tool as a regular user

In order to use the hamachi command line tool as a regular user, add the following line to the configuration file:

Ipc.User YourUserNameHere

Automatically setting a custom nickname

Normally, Hamachi uses your system's hostname as the nickname that other Hamachi users will see. If you want to automatically set a custom nickname every time Hamachi starts, add the following line to the configuration file:

Setup.AutoNick YourNicknameHere

You can also manually set a nickname using the hamachi command line tool:

# hamachi set-nick YourNicknameHere

However, this needs to be done every time Hamachi is (re-)started, so if you always want to use the same nickname, setting it automatically (as explained above) is probably easier.

Running Hamachi

Start up the (matt) daemon

$hamachi start

or, if you use systemd

#systemctl start logmein-hamachi

Now you have a whole bunch of commands at your disposal. These are in no particular order and are fairly self explanatory.

$hamachi set-nick bob
$hamachi login
$hamachi create my-net secretpassword
$hamachi go-online my-net
$hamachi list
$hamachi go-offline my-net

To get a list of all the commands, run:

$hamachi ?

Note: Make sure you change the status of the channel(s) you are in to "online" if you want to perform any network actions on computers in there.

Systemd

The logmein-hamachi^AUR AUR package also includes a nice little Systemd daemon.

If you feel like it, you can set Hamachi to start at every boot with Systemd:

systemctl enable logmein-hamachi

To start the Hamachi Daemon immediately, use this command:

systemctl start logmein-hamachi

Note: If for some reason, hamachi doesn't have a Systemd daemon, you can use one from here.

GUI

Various GUI frontends for Hamachi are available in the AUR.

For Hamachi 1:

• haguichi (Gtk2, mono)
• ghamachi (Gtk2)
• hamachi-gui (Gtk2)

For Hamachi 2 (beta):

• quamachi (Qt4)
• haguichi (Gtk2, mono)

Troubleshooting

Hamachi times out soon after launch

If hamachi stops working after a short period of time it can be that the client is timing out. Create ~/.hamachi/config and add the following to it:

KeepAlive 10

If you have problems connecting to some hosts

Check if they are using Hamachi 2. If that is the case, then it is a known issue with the Hamachi 2 client connecting to the Hamachi Linux client.

/etc/init.d/logmein-hamachi is not found

Replace that path with /etc/rc.d/logmein-hamachi.

Error when trying to run hamachi-init

If there is an error while trying to load libstdc++.so.5, you want to install it. This library can be found in the extra repository, so you can install it by running pacman -S libstdc++5.

If you get an error while trying to load libcrypto.so.0.9.7, a temporary solution is to create a link from /usr/lib/libcrypto.so.0.9.7 to /usr/lib/libcrypto.so by running ln -s /usr/lib/libcrypto.so /usr/lib/libcrypto.so.0.9.7.
