[Opensim-users] OpenSim with Hamachi (Fred Beckhusen)

[Fred Beckhusen]

It is likely to be no incoming ports are available.

~Fred Beckhusen

Try these in order using a web browser from your server,.

1. http://127.0.0.1:8002 <- gives a web page. Verifies that robust is 
running on the machines Network Card loopback adapter.

If not, start Robust.

Go to the next step only when this test passes.

2. Find your LAN IP with the dos command 'ipconfig'.

Use a web browser to go to your LAN IP, such as http://192.168.0.10:8002

You should get a web Page. If not, check your IP with the dos command 
'ipconfig'. It will be listed as an IPV4 address. While there make sure 
there is only one gateways enabled. This is usually 192.168.0.1.

Go to the next step only when this test passes.

3. Use a cellphone or some other PC connected to your LAN for this next one.

Navigate using a web browser on that OTHER device to 
http://192.168.0.10:8002.

You should see the web page.

If this fails, it is likely to be an antivirus program blocking a port 
such as the Windows Defender firewall. Turn them ALL off. Look for 
Malwarebytes or other installations that can block the port. I have 
troubleshot one machine that had three anti-viruses. You can turn them 
back on once you get it working, one at a time, and see when Opensim 
quits. Then add the necessary exclusions to that anti-virus program.

Go to the next step only when this test passes.

  4. All the above tests are LAN-based. So now try the router:

  http://canyouseeme.org on port 8002

This test must pass. If it does not the problem is either the router is 
not forwarding, or another firewall is blocking you. Usually this is 
when people realize they have their router plugged into another router 
that needs to port forward, too.

Look up your router manual. Go to http://portforward.com and look it up, 
too.

If this fails, it is also likely to be your anti-virus. It can also be 
the Windows Defender windows firewall. Turn them both off. Look for 
Avast and Malwarebytes or other installations that can block the LAN 
port. You have already proven it is not Opensim,  so there is no point 
in reinstalling the grid or restarting it.

Do not go to the next step until the above is working. There is no point 
until the above works.


5. Go to the network settings and click the properties of the Microsoft 
Driver for the Loopback Adapter. You should have renamed it 'Loopback". 
In the IPV4 settings, it should show the same address Canyouseeme.org 
shows as the address. The gateway is 255.255.255.0 No other settings are 
needed. Close those settings, and right click the adapter and enable it.

6. Navigate to http://(The Ip address reported by CanyouSeeme.org):8002

You should see the web page. If not, recheck the Loopback settings.

Go to the next step only when this test passes.

7. Right click the Loopback Network Adapter and disable it, if you have 
installed it. Navigate to http://(The Ip address reported by 
CanyouSeeme.org):8002. It may or may not work. If not, you need to 
re-enable the adapter. If it gives a web page, congratulations, your 
router supports loopback. Leave it disabled.

> Hello everyone! Have a question about using OpenSim with Hamachi (or
> similar personal VPN software).
>
> I have set up a grid mode installation (not Hypergrid) with the relevant
> IP/Hostname settings pointing to the IP address that Hamachi has set up.
> When I try to log into OS from another computer (that is not on the same
> network, and is also using Hamachi), I can see the login attempt in
> ROBUST and the attempt to connect to a region in an OpenSim.exe
> instance... But the log in never completes. I suspect this may have
> something to do with loop back, but I am not sure how to resolve this
> concerning using Hamachi. I can access other resources on the host
> computer just fine (such as network shares) and am able to ping it.

> Unfortunately, due to some recent circumstances that I was put in
> lately; I am temporarily staying somewhere else that I do not have
> access to the router to do port forwarding setup and all the other
> necessary things that need to be done normally on the router's side to
> allow other people to gain access to my regions. So I thought that
> Hamachi would be a great way to get by for now to allow a couple of
> people that need access to my regions to be able to log in with me... It
> just isn't working at present.
