Hamachi problems, can connect but not ping

[BCVisin]

I have installed hamachi on plenty of fedora distros and it has wored fine. I have been happy with it, but today I installed Ubuntu (YAY, not using windows anymore), but I can not seem to get it up and working. I am able to connect to the hamachi server and see all of the computers on the network, but I can not conenct out. I can't even ping any of the 5.x.x.x addresses. I thought it was the iptables, so I flushed them, but still no...

Out of ideas, any help is much appreciated.

I'm having the same problem.

I am using ghamachi on one (ubuntu 6.10) computer, and plain old hamachi on the other (ubuntu 6.06) computer. I am connected. They see eachother as online, but if I ping one another I get a respond from my local hamachi ip address saying Destination Host Unreachable.

I can ping my own hamachi ip address.

Thanks for any hints!

Seriously, has no one else had a similar problem?

I have the same problem. I installed the ghamachi but I can not do ping and browse the devices that are on-line.

[Bob Sugar]

Ditto. Same problem.

Any answers yet?

None here.

I'm having the same problem with Xubuntu 6.06.1 LTS (which as been updated).

I did however find that it was working for about 5 minutes. I was fiddling and realised that I had installed it under root and wanted it under a user so I ran it again under a the user and it didn't work then - what I mean is that it will not connect over the network.

I have MacOS running hamachi and Windows XP - they can both see that the Xubuntu computer exists but it is greyed out and can't reach Xubuntu by pinging 5.x.x.x even though I can ping with 192.168.x.x!

On Xubuntu I can see the MacOS and WindowsXP 'connected' but I can't ping them either with 5.x.x.x but I can ping with 192.168.x.x.

On Xubuntu I can ping the 5.x.x.x. and 192.168.x.x and both work fine.

There seems to be something in Xubuntu stopping the connection. I don't have a firewall installed to my knowledge.

I'm glad I'm not the only one having the same problem. I can't find any solution on the hamachi forums or on here though. I have installed and deleted all the files I don't know how many times to no avail, thinking that some combination was wrong.

Just goes to show sometimes it's best to put projects down and step away for a while. I fixed my problem - and hopefully this will help anyone else.

hamachi go-online <network name>

I was logged in and online, but somehow managed to missed this essential step.

Oh well - it's working now, hopefully this will help someone else.

If you got firestarter installed, stopping the firewall helps. Can anyone help figuring out why it is that way and how to configure the firewall so you don't have to shut it down?

I have the same problem, I'm in the room and I can see the other and they can see me as well, but I can't ping them. I get a 'destination host unreachable' message from ping.

Update:
I added this to /etc/network/interfaces:
(You can get your ips from ifconfig when hamachi is online (after hamachi start)

iface ham0 inet static address <your_ham0_ip> netmask 255.0.0.0 iface ham1 inet static address <your_ham1_ip> netmask 255.0.0.0 auto ham0 auto ham1

And I don't know it's important but after i go-online to a room restarted the network with

sudo /etc/init.d/networking restart

And after that i can ping the others and they can ping me too.
