View Full Version : [ubuntu] Hamachi Problems
July 12th, 2011, 10:03 PM
I'm having trouble connecting to people through Hamachi. It was working fine yesterday, but today I was trying to join a server on Minecraft, and it stuck while trying to connect, and when to ping it, the console just returns "ping: sendmsg: Operation not permitted" until I kill it. I get the same result when trying to ping anyone else on Hamachi, but not when pinging anything/anyone else. Does anyone know what the problem is?

Here is some information if that helps. The Hamachi interface is ham0.
Here is the output for "ifconfig ham0" :

And here is the output from "route -n"

I seem to be having the same problem. :(
I can connect to my friends' network and see everyone, but when I ping any of them I get the same result as Kexus: 'ping: sendmsg: Operation not permitted'.
They don't have the same problem with each other. However, the one other person who uses Linux (who has a dual boot, unlike me) seems to have the same problem when running from Linux.
Still, other people seem to be using Hamachi without such problems. What's going on?
I use the Haguichi front-end application thing now, but I had the exact same problem when I ran Hamachi from the command line earlier.

Oh hey. I think I've found the solution. ^^ With the help of http://www.ubuntu-forum.de/artikel/55821/hamachi-ping-problem.html
Well, it's the fire wall. It blocks Hamachi traffic. Turn it off and pinging works fine.
(Edit: And Terraria multiplayering works fine, too.)
