Chaining simulations connection issue 31/07/2022 at 14:26 #147393

Hi all, I am having some issues trying to chain Brighton and Lancing together, I have followed all the steps on the wiki with no luck at all, Brighton I have set up as port 50505 and Lancing as 50507, when trying to connect to Brighton it comes up in the client connections box that there is a connection.

After about 10 seconds that gets removed from the box and comes up saying that the server has disconnected me. I have tried everything I can with no success. Am I doing anything wrong here?

Cheers.

According to the Chaining Diagram, Brighton and Lansing dont chain.

I'm not sure that's true - I recall having chained them before. The chaining diagram doesn't list Brighton in the map part because it's been superseded by Three Bridges.

I believe you can use 0.0.0.0 instead of the 192.<etc> address as well to connect to your own host. That should be direct, instead of going through your router and being sent back to yourself, which can sometimes cause issues.

Thanks mate I'll try that, so do I just enter 0.0.0.0 into the IP address then?

Brighton and Three Bridges BOTH chain to Lancing, and still do. I believe this is because Three Bridges was built out from Lancing so have the same fringe at Hove?

Enter 0.0.0.0:50505 or whatever port you're hosting on. So it's the part before the : symbol that you replace.

Alternatively, you could also try localhost:50505 but I'm not sure SimSig accepts it.

I'm assuming you mean built out of Brighton

That didn't work, it instantly disconnected me as soon as I clicked connect

Try using 127.0.0.1 for the ip address

After 'Monday' and 'Tuesday' even the calendar says 'WTF'

just to make sure, when the connection appears in the box, you are selecting it and then pressing the "accept" button?

I think that proves it has been a long day! Too long for me clearly.

192.0.0.1 should be recognized by your own device's network card or network stack and turned around without ever leaving the machine.

0.0.0.0 is an unrouteable address; it doesn't come back to you. It's used for things like "accept any address" or "use all interfaces" on a server and "I don't have an address" in give-me-an-address protocols like DHCP. It DOES NOT mean "this machine". Most likely it will be sent to the default gateway which will then throw it away.

I think that means that the server hasn't accepted the TCP/IP connection yet.

Apologies for the wrong info. Not sure where I picked it up. I went and looked and 0.0.0.0 is in the list of past IPs I've tried to connect to in the loader. Maybe I got it swapped around with localhost (which then does work?) in my mind.

That strongly suggests that you've got a firewall running on your machine (Windows Defender?) which is blocking the relevant port.

If you open a command box (type cmd in the Windows search box) and then enter "ping 127.0.0.1", that will tell you if your networking loopback is working or not. If so, run the command "netstat -na" and look for "TCP 0.0.0.0:50505 0.0.0.0:0 LISTENING"; this shows that the server is listening.

Did you mean 127.0.0.1 here Clive?

You need to click on the incoming connection so it's highlighted in blue, for the Accept and Reject buttons to become "live".

But I agree with Clive it sounds like your firewall is blocking SimSig.

Stupid me: that's 127.0.0.1.

192.whatever that's assigned to your machine should be recognized by your network stack and not sent to the router.

Yes, I did. I was typing my apology as you wrote that.

Yeah I clicked on it and only the remove button was available to press.
