HOW-TO Secure Remote Access - Hamachi+VNC

**Randall Flagg** · February 2nd, 2009

well.. surfing a little on internet I found a really nice script...

go here, and see how it works.. it very easy..
https://forums.hamachi.cc/viewtopic.php?t=16590

And even as good this script was, I can't seem login with my ubuntu intrepid ibex...
everything goes fine, instalation, etc, but when I tried to login, nothing. It just said "failed"

so, I do some research, and see if I had all the necesary ports open.
So I add some rules with my firewall for ubuntu and "ufw allow"it opening ports 443, 32976 and 12975 .... but nothing, still wont login...
any clue?

Can someone tell is this tutoril still secure?
It was written 2 years ago... is it still safe? cause I am using it right now

Can someone explain me step with firewall?

For XDMCP -> only allow incoming connections from 5.x.x.x (Hamachi subnet) to Ports 6000-6009

For VNC -> only allow incoming connections from 5.x.x.x (Hamachi subnet) to Port 5901

How I have to do that? I am using Firestarter...

i keep getting an error in the termninal as soon as i get to section 1-e. "hamachi-init: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory" and i don't know how to get around this. i just want to know how to get hamachi networking for games.

How come I keep getting this error after adding the group and trying to add the user?

Code:

gpasswd: uknown user whatever

Of course the whatever is my real nick on Hamachi, but why isn't it working?

I think it is very important to say the following to those who do not know.
In section 1.C) Setting User Permissions

Adding user to the group hamachi
You should know that the username they want is the name of the account you are logged into Ubuntu with. So if you logged into Ubuntu with 'dan'
then you need to type:
sudo gpasswd -a dan Hamachi

That is what is causing my error of 'Unknown User'

Just wanted to clear that up.

I've been following this guide on 8.10 - my main computer (the three main flavors of ubuntu 9.04 soon to follow

)

Anyway, I've been following this guide step by step, and I made it to where I'm creating a hamachi network with the command:

Code:

sudo hamachi -c /etc/hamachi create network password

After completing this command, I don't get back to the glory of my bash prompt, instead I get:

Code:

veovis@Veovis-Ubuntu810:~$ sudo hamachi -c /etc/hamachi create veovis *********
[sudo] password for veovis:
>

I retyped the command (with a different password than I first entered), but I got the error saying that the network was already created. But whenever I use the original password in that command, I get the same output. Also, the go-online command gives the same ">" prompt
Did I use an invalid password or something? There were no spaces, but I used dice (a d4, a d12, and a d10, PM me if you'd like to know how.) to make the password and I might have used invalid characters accidentally. If so, I'm really attached to that network name, is there a way, if no one has logged in yet, to delete it and get the name back?

I'm getting this problem when I type 'hamachi start'

Code:

09 00:19:32.214 [   0] [25054] tap: connect() failed 13 (Permission denied)

I'm successfully running Hamachi when my Ubuntu is directly connected to internet. But, at my workplace, we have to use a local proxy to access the internet. The Windows version of Hamachi has an option for tunneling through a proxy, but I can't find a command or config file for Hamachi in Linux. Any ideas?
