Custom Server tutorial

8GB, and you mean how much have I allocated to my modpack in the launcher? 2GB, jumped that up to 3GB now though.

My friend I believe is also about the same, I have him hosting so I can see the lag issues now and I get the exact same as he did. There is no single player lag, or lag on the server if you are the one hosting, so I figure it may be a problem with server ram.

Wait, so you get no lag when connecting to the server running on the same local machine but a remote person does? Could be bandwidth issues. What is your upload/download speeds? speedtest.net

38 ms ping, 3.19 mbps DL, 1.24 mbps Up

I don't have any lag issues on any vanilla servers, haven't tried any modded ones though. And usually no lag with any other games, often tend to be first one loaded etc, doubt it's that.

 

Is any of these bukkit setting possibly relevant?

Nope, you can leave those at the default settings. And yeah, 1.25 up isn't amazing but it should be enough for a couple people. When the other person is trying to connect and is experiencing major lag what is the server TPS at?

My friend who is hosting atm has a DL rate of about 90 mbps and upload of over 10 mbps, so I doubt it's his lag either. I'll check tps next time we do it, It seems the lag is upon login, and teleporting to new area.. Pretty much loading chunks, not necessarily brand new chunks either. Then My game will slowly catch up, and I will see everything at like double speed for a couple mins

 

Edit: The server tps was at 19.2 while I was lagging, and once I started loading it went to 20. After logging in I tried typing in chat, walking around our base and opening chests.. for me nothing until about 5 mins later, but my friend saw me moving during the time and my text, almost like it's just client-side...

Double posting to refresh the post, a 2 day edit doesn't work so well. I had to delete hamachi which we tried using for LAN, didn't work.. apparently that's the IP we were using for servers, and was probably screwing everything up. So I must ask, how do I get the IP for the server? I can't find out from anywhere and it's really pissing me off that something so simple is wrecking everything. -.-

@Slayer19

 

If you aren't using Hamachi (and you really never should) you leave the IP settings in the server.properties file blank. You have to open a port through your firewall/router which is redirected to your local PC on the same port your MC server is running on (default/typical 25565). You can see your public IP and test the open port (when the server is active) here: canyouseeme.org

Hi, thanks for your tutorial.  I've tried making a server tons of different ways by now, and none of them seem to be working.  I'm trying to set this up so my friend can run a server of the modpack I made.

 

I think I deleted all the client side mods and their config files, but I'm not sure... also hopefully mods like the Hats Mod and the Smart Moving Mod count as clientside only, cause I deleted them.

 

Here's my latest crash report:

I think I deleted all the client side mods and their config files, but I'm not sure... also hopefully mods like the Hats Mod and the Smart Moving Mod count as clientside only, cause I deleted them.

Hats is not a client-only mod.

 

What version of MCPC+ are you using?  It seems like you might be missing a library.

First of all, thanks for your help in my other thread. My pack works in single player now obviously :D

 

And I didn't see anything about downloading MCPC+ in this tutorial, I saw you post about it in another one, but when I try to download the 1.6.X files, I get a error saying I couldn't connect to the page. Is there a way to add the libraries without download MCPC+ directly?

 

Edit: don't really know how to quote right xD

Thanks for your help again!

The libraries looked to be the same, but when I replaced it with yours, it seemed to work fine.  My friend is trying it out in half an hour!

It's a scala issue, I had it on my modpack. Download scala-library-2.10.2.jar again and place in the appropriate libraries folder. For good measure, update your java to Java 7 Update 51.

@DiddlyDoo802: I recently saw that when debugging someone's custom pack. If my memory serves (and it seldom does) that error might be related to you having the MCCapes mod on your server. That mod doesn't work on an SMP server.

DiddlyDoo802: You are missing the required libraries. Are you using MCPC+ (Now called Cauldron)? If so then you need to be using the latest version (Build #272 if I'm not mistaken).

i am using the .jar file provided in the very first post on this thread. and i believe that it has mcpc+

 

UPDATE: I took off the mcpc+ server jar and used a forge version instead (i didnt really need bukkit). My server is now working. Thanks for the help!
