Downloading Terrain?

When I or anyone try to connect to my Craftbukkit server (or even default minecraft server software), it hangs at "Downloading Terrain" and gives a disconnect.genericReason error in the cmd.

I can connect to the server fine with localhost.

Any suggestions? I've enabled 25565 as an exception in Windows firewall.

Do you have any plugins enabled?
What version of CB are you running?
http://forums.bukkit.org/threads/you-need-help-we-need-this-information-to-help-you.2018/

I have several plugins enabled, but I get the same problem when I disable them or run the stock Minecraft server. I have the latest version of CB.

Windows 7 64 bit, as well.

random shot.. does windows think your local network is public or private/office?

It just shows it as a home network.

i THINK that means it trusts other computers... so much for that idea

you say it works with a client on the same physical machine as the server, but not other machines.
have you tried another machine on the same network (so behind your router/modem)?

A few more pieces of info:

- It hangs at "Logging in" for everyone, and it only hangs at "Downloading terrain" for me.
- I've allocated 1024mb of ram to the server, with no change in performance.
- Modem: Motorola SB5101U
- Router: Netgear Wireless-N 150

This is probably a dumb question, but it keeps bugging me. Your symptoms sound almost exactly like the results of trying to use a new minecraft client with an old server (from back when MC went from alpha to beta)

the fact that the forums are not flooded with this probably means that notch hasn't pushed a new client, and the fact that you can connect with a local client probably invalidates in anyhow, but I figured i may as well throw it out there.. your client/server ARE up to date, right?

Ok, I just tried connecting with another computer and it hangs at "Logging in" every time. It could be just me hanging at "Downloading terrain" since I didn't verify with other users.

So every user hangs at "Logging in", and I (running on the server machine) hang at "Downloading terrain".

Edit: Yes, client and server are newest version.

you said in your original post that it worked if you connected via localhost. generally that indicates a client running on the server..

can you confirm if that does or does not work.. because that changes everything troubleshooting wise

If I connect via Localhost, it connects fine. If I connect with the external IP address, it hangs.

I just set up a static IP address, and now I can't even connect to the server.

Any thoughts?

Edit: I can still connect via Localhost, just not external IP.

Here's one thing to consider...

Most of the time, when you setup a port forward, you do something like 10.0.0.220 (computer IP) forwards port 25565 to external. However, if your computer's IP (NOT the external IP) changes, then it can't find it unless you connect via localhost OR fix the computer's IP as static at 10.0.0.220 (example).

Though that (above) is a bit of a different thing, it's semi-possible some of the problems are caused by this.

I just changed the port forward to my new static IP, and I'm back to the same problem.

i've asked this, but not quite sure i've gotten a direct answer.

if you connect using a different physical machine, on the SAME physical network, what happens?
you would use the internal IP of the server for this (or its name)

[assuming you are not familiar w/ networks, i'll explain .. if you are, then you can just ignore the rest of this message] [numbers pulled from a dark dark place, and are not likely to match exactly]

ISP (cable company) --------- ROUTER --------------------- SERVER
66.66.74.1..........66.66.74.43...192.168.1.1.......192.168.1.10

other computer: 192.168.1.15

other computer would connect to 192.168.1.10:25565

that will verify if your router is stopping the traffic or if the server is doing it.

Trying this right now.

I tried this, and it gives the same problem; hangs at login, and disconnects.

and you definitely have an entry in the windows firewall to allow craftbukkit in/out?

I don't know how to let a Java program through the firewall, though I do have the port opened through it.

in AND out?

i guess you could let JAVA.EXE through, but that seems like a REALLY BAD IDEA

In and out, yes.

I thought this might help.

several dumb questions:

1. did it ever work?
2. how does the server handle other network traffic (loose cable, bad card/port/etc)

It has never worked, save for me directly connecting with localhost or server IP.

The server computer has served as my main computer for a while, and it handles internet gaming like a pro.

On a side note, I briefly attempted to hook up my gaming laptop (on the same network) as a server and ran into the same problem.

what os is on the laptop?

Same as the server, Windows 7 64 bit.

I really do wonder about your theory; could the router/modem be completely stopping the connection as the player logs in?

usually they do not restrict internal traffic.. (LAN side)

unless you have a switch or crossover cable laying around, it will be difficult to verify that though.

I don't know what else to try, other than assume that my router/modem will not let people connect to the server.

quoting TNT to bring him in here for second opinion..

what about an ubuntu live cd and a usb disk?
yeah it will be slower than dirt, but it will eliminate windows from the equation...

@Macks

if my previous post made sense to you, try it..

1. put craftbukkit on a usb stick
2. download an ubuntu live cd
3. boot from the cd
4. insert the stick
5. try running craftbukkit and connecting

if that doesn't make sense, hold off until i get a second opinion before i provide more detail
