ปองพลบล็อค: Installing hamachi VPN in Ubuntu as a service

เครดิต http://the-ubuntu-linux.blogspot.com/2010/09/installing-hamachi-as-service-in-ubuntu.html

Hamachi is a free vpn service, useful to create a private LAN over the internet. For more details of hamachi, go to www.hamachi.cc

The following covers installing hamachi in Ubuntu as a service.

We start with installing the 'tun' module to enable IP tunneling in linux

sudo modprob tun

(If that gives an error tun module failed try installing faketun as given in the blog post Installing faketun)

Open the modules file and add ‘tun’ to the list

sudo nano /etc/modules

Your file should look similar to the example below.

# /etc/modules: kernel modules to load at boot time.

#

# This file contains the names of kernel modules that should be loaded

# at boot time, one per line. Lines beginning with "#" are ignored.

lp

rtc

tun

(Incase 'tun' is not on that file, write 'tun' in a new line)

Save the file and exit out of nano (Ctrl-O to save & Ctrl-X to exit), lets move on and verify that a tunneling node has been created. (*If you have compiled your own kernel you likely need to recompile it with IP Tunneling support if you receive an error with modprobe. This is not covered in this guide. And if you are unsure, you most likely did not compile yourself and you would definitely remember doing so.)

ls /dev/net/tun

You should recieve a response like the example below

/dev/net/tun

If you received something along the lines of “No Such File or Directory” you may need to manually create the node (run the commands below). If you received the response (/dev/net/tun), jump to the next step.

sudo mkdir /dev/net

sudo mknod /dev/net/tun c 10 200

Run ls /dev/net/tun again and you should now receive the correct response.

With our IP Tunnel node created, it is time to install Hamachi itself. First download the latest version. As of writing this guide, the latest version is 0.9.9.9-20

wget http://files.hamachi.cc/linux/hamachi-0.9.9.9-20-lnx.tar.gz

Expected output below

Navigate into the extracted directory

cd hamachi-0.9.9.9-20-lnx/

Start the installation

sudo make install

Expected output below

Copying hamachi into /usr/bin ..

Creating hamachi-init symlink ..

Compiling tuncfg ..

Copying tuncfg into /sbin ..

Hamachi is installed. See README for what to do next.

Run the tunnel

sudo tuncfg

This should complete the install, we will now configure the user permission in order for it to run correctly. Create a ‘hamachi’ user group

sudo groupadd hamachi

Add youself as a user to the ‘hamachi’ group. Be sure to replace your user name where appropriate.

sudo gpasswd -a YOURUSERNAME hamachi

Add the root user to the ‘hamachi’ group

sudo gpasswd -a root hamachi

Set the correct permissions for the tuncfg socket

sudo chmod 760 /var/run/tuncfg.sock

Change the ownership of the socket file

sudo chgrp hamachi /var/run/tuncfg.sock

That should do it for the permissions, Now onto setting Hamachi up & configuring it to start as a system service.

sudo hamachi-init -c /etc/hamachi

Expected output

Initializing Hamachi configuration (/etc/hamachi). Please wait ..

generating 2048-bit RSA keypair .. ok

making /etc/hamachi directory .. ok

saving /etc/hamachi/client.pub .. ok

saving /etc/hamachi/client.pri .. ok

saving /etc/hamachi/state .. ok

Authentication information has been created. Hamachi can now be started with
'hamachi start' command and then brought online with 'hamachi login'.
Start hamachi

sudo hamachi -c /etc/hamachi start

( sudo service logmein-hamachi start )
( sudo /etc/init.d/logmein-hamachi restart)
Expected output

Starting Hamachi hamachi-lnx-0.9.9.9-20 .. ok

Set your computer’s nickname

sudo hamachi -c /etc/hamachi set-nick "COMPUTERNICKNAME"

sudo hamachi -c /etc/hamachi login

To join an existing network (optional) “NETWORKNAME” and “PASSKEY” should be replaced with your network name and network password

sudo hamachi -c /etc/hamachi join NETWORKNAME PASSKEY

To create a new network (optional) “NETWORKNAME” and “PASSKEY” should be replaced with your network name and network password

sudo hamachi -c /etc/hamachi create NETWORKNAME PASSKEY

If you joined an existing network you must tell hamachi to then “go-online”. Be sure to replace NETWORKNAME with your relevant network name.

sudo hamachi -c /etc/hamachi go-online NETWORKNAME

Check your hamachi status to verify everything is as it should be

sudo hamachi -c /etc/hamachi

Expected output

Hamachi, a zero-config virtual private networking utility, ver 0.9.9.9-20

  version : hamachi-lnx-0.9.9.9-20
  pid : 5754
  status : logged in
  nickname : NICKNAME(assigned nickname)

Now to configure to startup and login automatically when the computer starts:
Create the startup script file:

sudo touch /etc/init.d/hamachi
(Else you can download the file directly from here. Place it in the /etc/init.d folder.)

Open the startup script file for editing (Incase you have downloaded the file and placed in the /etc/init.d folder, you need not do this step)

sudo nano /etc/init.d/hamachi

Paste the following contents in the file:

#!/bin/sh

### BEGIN INIT INFO

# Provides: hamachi

# Required-Start: $remote_fs $syslog $network

# Required-Stop: $remote_fs $syslog

# Default-Start: 2 3 4 5

# Default-Stop: 0 1 6

# Short-Description: Start hamachi at boot time

# Description: Starts up hamachi daemon. Networking is required.

### END INIT INFO

hamachi_start() {

  echo "Starting hamachi..."

  /sbin/tuncfg

  /usr/bin/hamachi -c /etc/hamachi start

  /bin/chmod 760 /var/run/tuncfg.sock

  /bin/chgrp hamachi /var/run/tuncfg.sock

}

hamachi_stop() {

  echo "Stopping hamachi..."

  killall tuncfg

  /usr/bin/hamachi -c /etc/hamachi stop

}

hamachi_restart() {

  hamachi_stop

  sleep 1

  hamachi_start

}

case "$1" in

'start')

  hamachi_start

  ;;

'stop')

  hamachi_stop

  ;;

'restart')

  hamachi_restart

  ;;

*)

  hamachi_start

esac

Save the file Ctrl+O and exit nano Ctrl+X

Make the file executable and configure it to run it at startup:

sudo chmod +x /etc/init.d/hamachi

sudo update-rc.d hamachi defaults

Expected output
Adding system startup for /etc/init.d/hamachi ...
/etc/rc0.d/K20hamachi -> ../init.d/hamachi
/etc/rc1.d/K20hamachi -> ../init.d/hamachi
/etc/rc6.d/K20hamachi -> ../init.d/hamachi
/etc/rc2.d/S20hamachi -> ../init.d/hamachi
/etc/rc3.d/S20hamachi -> ../init.d/hamachi
/etc/rc4.d/S20hamachi -> ../init.d/hamachi
/etc/rc5.d/S20hamachi -> ../init.d/hamachi
