For those of you which need to access by means of “Remote Desktop” you can use :

• Nomachine NX
• Teamviewer
• VNC

And you can use both LogmeIn Hamachi and VNC. Hamachi is a software which can make network betweeen devices. Against logmein product which lot of you know, here it is at ~~Level2~~ (OSI).

How you create your VPN ?

For Linux users, you must install vnc4server and hamachi (supplied by LogmeIn) package (dpkg is your friend). Then you launch your vnc server :

root@plop# vncserver 
New 'plop:1 (clucas)' desktop is plop:1

Starting applications specified in /home/clucas/.vnc/xstartup
Log file is /home/clucas/.vnc/plop:1.log

Now the VNC server is reacheable by means of 5901 (5900 + 1) port.

Then you can create your VPN network by using hamachi :

root@neptune:~# hamachi -h
LogMeIn Hamachi, a zero-config virtual private networking utility, ver 2.1.0.76

  usage: hamachi [command]

  command    specifies an action. Can be one of the following -

             #  set-nick 
                login
                logon
                logout
                logoff
             #  list
                peer 
                network 
             #  create  []
                set-pass  []
                set-access  [lock|unlock] [manual|auto]
                delete 
                evict  
             #  approve  
                reject  
             #  join  []
                do-join  []
                leave 
             #  go-online 
                go-offline 
             #  attach 
                attach-net 
                cancel
             #  gw-config 
                    [dhcp|static [net    ]
                                 [domain ]
                                 [dns  []]]
                    [del  ...]
                    [add  ...]
             #  set-ip-mode ipv4 | ipv6 | both
             #  check-update
                vpn-alias  |0
  If no command is specified, hamachi displays its status including version,
  pid, client id, online status, nickname and the LogMeIn account
root@neptune~# hamachi attach clucas@altern.org
root@neptune~# hamachi join network password
root@neptune~# hamachi go-online network

You have now access to your Linux server/desktop from anywhere by means of hamachi’s device :

For mac users (such as me : not a really experimented user), you have a built-in VNC client in MAC from 10.5 MAC OS X.

Go in your finder window > Go > Connect to server >
Now you can access to your device by means of :
vnc://x.y.z.w:5901 (where 5900 + X display : here :1)
