Java issue with master server

This error is the reason I dropped multiverse last time. After trying EVERYTHING in EVERY post about this error , no one including me was able to figure out how to fix this:

This only occurs when attempting to run a MASTER server . I need to be able to do this as I have my server setup on a SERVER machine and want to develop using a standard pipeline. AKA: Development server runs 24/7 and is setup like a production environment. Client is used to access server and do what needs done, patcher is in place and functioning.....ect. It does not make sense to run the server and client on the SAME machine as before long you will find yourself too far into development to FIX it if the remote connectivity is never tested and fixed and or improved if need be. This is also nessasary if you want to CLUSTER your zones in sandbox fasion.

You are getting that error because you need to generate a private key and put it in the master_server.py If you run gen-masterserver-keys.bat it will output your private key into masterserverkeys.txt copy the encoded private key and put it in master_server.py where it says to put it but with only one set of quotes and no endlines.

You will also need to put the encoded public key into login_manager.py in the config/common folder again with no endlines and one set of quotes.

(Obviously dont share your keys or someone can fake the authentication method and login directly to your game server.)

delurin,

one thing that is confussing,

when we generate a new masterserverkeys.txt
it does generates several keys.
domain key:
private key:
public key:
encoded private key:
encoded public key:
encoded domain key:
master token data:
imported master token:
domain token data:
imported domain token:

which one exactly are we supposed to use?
and what are the rest of them used for?

The encoded private key is for the master server. The encoded public key is for the game server. The unencoded set of keys is probably just in case you want to recreate the keys and are probably unnecessary. I am not sure what the others are used for but I am going to guess that the domain keys are for distributing the server across multiple machines. Possible for across different networks.

I get this when running gen-masterserver-keys.bat

Code:: Mike@Mike-PC /cygdrive/c/multiverse/master
$ ./gen-masterserver-keys.bat
.\masterserverkeys.txt was unexpected at this time.

So I cant even generate a key right now, any options?

It's a bat file I think you just want to run it from the folder

I am not sure anyone has written one for cygwin/linux yet but since it only needs to be run once it shouldnt be that hard to find a windows box to run it once.

Ok its now atleast attempting to start but i get this using the batch file and cygwin still has the same issue .

DONT worry, I changed alot of the characters in the keys BEFORE posting this so, these keys are not even close to correct lol Just wanted you to see how they are in the file.

and Louis, take the check for the textfile out of it at the top and it will run and generate the masterkeys and write them to the file. If i remember right that is in there to prevent you from overwritting the file if you have already generated the keeys and used them.

put the key all on one line the \n character is an endline so it is saying that the privKey cannot equal endline

Thanks, was just opening it up when I read your reply

so in laymans terms, all on one line and remove the backslashes?

dont remove the backslashes but yes all in one line

new cygwin output. hate to keep pestering you with this but im pulling my hair out at this point lol.

I believe I ended up using the windows command line to run it because I couldn't get it to work right away let me see if I cant the cygwin version running real quick

This is what I end up getting when running from Cygwin, any thoughts?

Ah ok When they moved the master server from the mv_home/bin they did not update the master.sh file to reflect that it is no longer in the bin folder here is my updated version that works Ill try to figure out how to change it in the repository some time soon

Hmm Ignore that last one it looks like the git repository has the correct master.sh/directory I recommend you go make sure it is update with that one.

I never tried Cygwin. I went straight up using a virtual machine like VMWare Player and Centos 6 x64. It is better simulating the linux environment.

Here's my master_server.py if you're interested. It's simple and auto generates the keys, less confusion:

Code:: from multiverse.server.engine import *
from multiverse.server.util import *

ms = MasterServer.getMasterServer()
#ms.setTCPPort(9005)
#ms.setRDPPort(9010)

# Uncomment if you want to set a log level for this process
# that is different from the server's default log level
#Log.setLogLevel(1)

pair = SecureTokenUtil.generateMasterKeyPair()
encodedPrivKey = SecureTokenUtil.encodeMasterPrivateKey(12, pair.getPrivate())

SecureTokenManager.getInstance().initMaster(encodedPrivKey)

Hope that helps.

That is what I came up with originally but it doesn't let you put the master server on a different server than the game server. And I dont think it will work with the load test work.

Oh ok, thanks for the info Delurin.

ok changing out the "multiverse complete" master.sh with the one from the git repo and then MOVING prop2sh.awk to the master directory I get mixed results, sometimes the server starts and runs till i shut it down with ./multiverse.sh -v stop and other ( most of the time ) it CLAIMS to start then must stop at the tail end of the process and dumps this error in master.out:

Code:: ERROR [2013-04-16 19:43:13,202] main MasterServer.main caught exception java.net.BindException: Address already in use: bind

Im thinking I may have to specify a static IP somewheres or FQDN but Im at a loss as to where?

Code:: ERROR [2013-04-16 16:51:22,748] main MasterServer.main caught exception java.net.BindException: Address already in

I get this when starting up the master now..no idea lol

I am guessing that it doesnt release the socket...you may want to close down cygwin or whatever you are using instead of stopping/restarting it. I will take a quick look but I just let it run when I start the server and only stop it when I shut the server down.

I may have stumbled onto something.

I added the info from the top of multiverse.properties :

Code:: ### Server host names and ports
multiverse.msgsvr_hostname=192.168.1.150
multiverse.msgsvr_port=20374
multiverse.worldmgrport=5040
### Proxy server settings. To enable remote clients to connect, specify IP address or DNS hostname
multiverse.proxyserver=:192.168.1.150
multiverse.proxyport=5050

to master.properties and the server starts and runs every time! this is missing in master.properties. Now i cant figure out what port to use to connect with JMX to confirm it and keep getting connection refused in jaconsole so i assume it acculy is running, but ./multiverse.sh -v status reports RUNNING everytime i stop then restart it. Still not getting "done initializing ......" but if left for 10 min and status is run again , still reports as RUNNING. Now i just have to get a client to connect and i think we may have this one in the bag!

I forgot to mention that it doesnt give an initialized message even after it has started... I believe they just copied the multiverse.sh and modified it to run the master so it probably was just left in accidently.

I am not sure why you need to add the info from the multiverse.properties since it is only needed for the game server and not the master server unless were you waiting for the world initialized message? If so then yes you might need to connect to message server in order to receive the message that world has initialized but that is not necessary for the master server to run

ok now im getting this in the client log when I try to connect and nothing but a white screen with "Platform tutorial for setting up bla bla bla... accross the top.
