Hello, This is a post I recently made at my blog here. Thought it might help some of those who are looking to install Hamachi on their tablet!

Note: For the commands below I will have assumed that you have already installed the openssh server so you can access the N800 via an SSH client with root access. You can also use the built in Xterm and gainroot but it is a pain in the *** typing all of those commands in via the touchpad. If you are using gainroot some of the directories below will change, for example Hamachi will install in /home/user/.hamachi instead of /root/.hamachi. Also I downloaded the client to my memory card in /media/mmc2/ but you can put it anywhere.

Your login should look like this:


BusyBox v1.6.1 (2007-09-27 18:08:59 EEST) Built-in shell (ash)
Enter ‘help’ for a list of built-in commands.

Nokia-N800-51-3:~#

Make sure wget is installed:

apt-get install wget

Make to get the latest Logmein Client from http://files.hamachi.cc/linux/nokia-770/.

Just follow my process below for installing the Hamachi client and joining your network.

Hamachi is now running on our little tablet!

But it has not joined our network at this point, so we follow the logmein Hamachi documentation to do so.

Nokia-N800-51-3:~# hamachi set-nick DaveN800
Setting nickname .. ok
Nokia-N800-51-3:~# hamachi login

Password:
Joining YourNetwork .. ok
Nokia-N800-51-3:~# hamachi go-online YourNetwork
Going online in YourNetwork .. ok
Nokia-N800-51-3:~#

And now…checking other Hamachi clients, shows our little device is online!

Now we need to tell our tablet to put hamachi online whenever we restart the system and also set the keepalive lower.

To lower the keepalive:

Nokia-N800-51-3:~/.hamachi# echo "KeepAlive 20" >> ~/.hamachi/config

This is all great, and you should be online now. But you would need to start Hamachi on every reboot which isn’t going to cut it. We will add the Hamachi start process to the init scripts. Add the following lines to the file ‘/etc/init.d/rcS’ right before the line which says ‘exit 0′

/sbin/tuncfg;/usr/bin/hamachi -c /root/.hamachi start

In order to do this, use VI.

vi /etc/init.d/rcS

* Press capitol ‘G‘ to scroll to bottom of the file
* type ‘i‘ to enter insert mode
* hit up a few times to a blank line before exit 0, or hit enter at the beginning of the line to create a new line.
* Paste the above line into the file
* Press “esc” using the special xterm button, or hit escape if you are using ssh.
* type “:wq!” — this command enters the command, mode, tells it to write the file, then quit and execute

That should be all you need! Power off the N800 and power it back up. After restarting your N800 you should see it connect to your PVPN Hamachi network and be online!

Let me know if you have any problems or comments about the above installation procedure!

LF .install/gui

This is awesome, you are pretty much my hero .... now i can vnc all my computers securely from starbucks

If you've got everything already set up on Hamachi, this is a great way to go. Thanks for the howto.

If you don't have Hamachi set up, ssh (and sshfs) can do the same thing. It means setting up an ssh server on your home network, however, and then making sure all required network shares are mounted on that server (so you can mount them on your tablet via sshfs). With ssh, you also need something like no-ip.com (so you can find your home IP address, even if it changes) and some knowledge of how to open ports on your router. As far as I understand, Hamachi does a lot of that automagically.

This is awesome! Thanks so much! One question, though. With the Himachi gui on the desktop, there is a 'browse' option that lets you interact with your network shares, but I can't figure out how to do this on the tablet. Nokia's partial Samba implementation thru the file browser doesn't pick up the Hamachi network. Any ideas how to view/copy/transfer files with the tablet over Hamachi?

Thanks

Use your internet browser. Put the hamachi ip address of the box you want to see in your browser. Like 192.168.0.0/home/

Could'nt get the browser to pull it up, but a program called wizard mounter works perfect.

i had this working on chinook, but since i upgraded to diablo and followed these steps again, hamachi does not automatically start.

If i try to run hamachi using "hamachi start" in a terminal while i am not logged in as root i get an error "Cannot access lock file /home/user/.hamachi//.lock"

if i login as root then i can start hamachi without problems.

Any ideas guys?

Thanks

I sold my N800 (I know, I know) but since it acts like a normal linux system, it should be an easy fix.

My guess is that it was run as root before and the .lock file may have root permissions on it. If so, try to remove it (it should be off anyway if hamachi isnt running) so that the user 'user' can create it with the right permissions.

As a last resort, you can try to launch hamachi as root, I don't recall if that works or not.

It should treat // as / so that shouldn't be the issue.

The rm command is correct -- You can use "ls /home/user/.hamachi/.lock" to see if it still exists after you remove it.
