Reason: Needs to be updated for Help:Style compliance. (Discuss in Talk: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.

Initial Configuration

To run Hamachi you need /dev/net/tun.

This is created by the tun module. As root, run:

modprobe tun

Or you can manually create /dev/net/tun by running:

mkdir /dev/net
mknod /dev/net/tun c 10 200

Also, make sure to add the "tun" modules to rc.conf so that /dev/net/tun is created next time your computer turns on.

Download And Install Hamachi

Manual installation

Tango-inaccurate.pngThe factual accuracy of this article or section is disputed.Tango-inaccurate.png

Reason: Why use make install and skip package management? (Discuss in Talk:Hamachi#)

Head to hamachi.cc and download their Linux client.

Untar it:

tar zxvf hamachi-x.x.x-x.tar.gz


cd hamachi-x.x.x-x
make install

And run tuncfg:

cd tuncfg

Run hamachi-init:


And that's the installation.

Hamachi 2 (beta)

Version 2 of the Linux Hamachi client exists and is currently in beta. It is available from the labs page on the Hamachi website; however, the vendor's tarball requires LSB and will not install correctly. You should use the logmein-hamachiAUR package from the AUR instead.


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

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.

As a Daemon

You can run Hamachi as a daemon this way:

Copy your configuration to /root directory:

cp -R ~/.hamachi /root/

Create a script in /etc/rc.d/ called hamachi using your preferred editor:

. /etc/rc.conf
. /etc/rc.d/functions

DESC="Hamachi VPN client"

case "$1" in
        #Check for running tuntap, start when not running
        ck_daemon tuntap && /etc/rc.d/tuntap start
        stat_busy "Starting $DESC"
        $DAEMON -c /root/.hamachi $1 > /dev/null
        if [ $? -gt 0 ]; then
            add_daemon $NAME
        stat_busy "Stopping $DESC"
        [ -f $PID_FILE ] && $DAEMON -c /root/.hamachi $1 > /dev/null
        if [ $? -gt 0 ]; then
            rm_daemon $NAME
        $0 stop
        $0 start
        echo "usage: $0 {start|stop|restart}"
exit 0

Remember to add hamachi to your daemons array in /etc/rc.conf, it should be put after tuntap.

And do not forget to:

chmod +x /etc/rc.d/hamachi


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)


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.
