I did some initial testing with hamachi but there must be something I haven't understood there yet.. I'm scratching my head a bit at least.

I have hamachi installed on my desktop (linux box). tuncfg is running at all times (as root). I start hamachi from my user account, hamachi-init, hamachi start, hamachi login, hamachi create, hamachi join.

Then I installed it on my n800, set it up the same way, then hamachi-init, hamachi start, hamachi login, hamachi join.
I can see stuff with 'hamachi list', including the 5.x.x.x. IP of my desktop computer.

I try to ping one from the other, or ssh, or 'telnet 22', anything. I always get 'no route to host'. My desktop is on the internal network, my N800 on an external wi-fi (outside the firewall). I don't see immediately how it _can_ work, actually.. unless it's tunneling through an external hamachi corp. box, but from the docu my understand is that it's not supposed to.

Anyway, apparently it works for others, so what am I doing wrong?

You are missing hamachi go-online. I had same problem two days ago, solved that way.
btw, you can also use ghamaci from your desktop.
HTH

I've tried with go-online too (sorry I forgot to list it in my post), it still doesn't work.

Some more investigation: When I do 'hamachi list' on each device I see:
* [my network name]
x 5.x.y.z

on each device, with each other's 5.x.y.z address. Reading the docu 'x' means '.. the peer is unreachable, ie the mediation server failed to establish p2p tunnel between you and the peer.'.
So I guess that's where the problem is. I wonder what could cause this. Anyone found a FAQ for hamachi yet?

Are you perhaps NATted with firewalls out of your control? Sorry, no FAQ. I looked a lot to solve my problem (behind a NAT with a 5.x.y.z internal address!) and found something interesting on Hamachi.cc forums. Nothing more than that.

I'm NAT'ed, but I thought it should be able to handle that - most networks that needs VPN are like that. I'm assuming that the way hamachi works is that each client is connected to an external hamachi server, then when two clients connect they use the info on the common server to negotiate an UDP tunnel directly between them. Or something like that. I'm guessing that these UDP packets are somehow being blocked in my firewall, although Skype (which does something similar) works fine on my nets, as far as I can tell.
So, I'm going to try hamachi between some other networks. I was hoping I could use it here though.

well i'm still having trouble...
hamachi wont start.
in xterm as user. hamachi-init. then hamachi start and it tells me no such file or directory.......?????

any clues?

You need to start tuncfg in the /sbin first.

Good luck. I managed to get it working after 2 hours of playing round.

how do i start tuncfg though?
