"Perhaps a server is already running on this port" - Help Me :)

Hey ! I made a server working fine then i was messing around and i deleted it by accident..
so i made the server again and when i click the "server.command" to run the server i get this message : "Perhaps a server is already running on this port" ! I am NOT using hamachi if that helps

Restart, see how it goes

Go into task manager and stop all java.exe applications (java.exe, javaw.exe, jusched.exe).

restart server.
And then it should run properly again

I stopped the script and clicked it again and it said the same thing !

Im on mac :L So i don't have task manger!

Restart the whole computer

Exactly what I meant

Terminal

/agree

Nothing happened

Then set the port to something but 25565

The port is 25565

Close all java processes. LEAVE server-IP= in the server.properties BLANK! Your friends can join with your IP (http://whatsyourip.com/) and you can connect with the IP; localhost:25565 (or with an other port you use).
NOTE: you must have port forwarded! Don't know how? Search on the internet, there are many tutorials!

I'm on mac too.just go to activity monitor, then find java.then quit process.you can find it in spotlight. hope i helped!

I'm on mac too and I really need help. I made a sever but I can't build on it can someone help me? I tried to make the server again but it says,
Perhaps a server is already running on that port?
So I have two problems, maybe someone can help me?
I'm on Mac.
Thanks!!!

People can be seriously retarded something.

1. Are you OP? Did you remove the shitty built-in spawn protection in bukkit.yml?

2. That message should explain anything you need to know, close the other server goddammit.

Im on a mac and I just finally made a server but when i try to go on it, it says

[INFO] Starting minecraft server version 1.2.4
18:19:57 [INFO] Loading properties
18:19:57 [INFO] Starting Minecraft server on *************:25565
18:19:57 [WARNING] **** FAILED TO BIND TO PORT!
18:19:57 [WARNING] The exception was: java.net.BindException: Can't assign requested address
18:19:57 [WARNING] Perhaps a server is already running on that port?
HELP!!!!

@jedi_nipl, remove the censoring. Don't worry, we won't hack you, just need to know what it is

Actually scratch that, set the server-ip back to it's default setting of nothing. Should fix it

Code:

server-ip=

Ok what you need to do is this change your port from 25565 from 65534 here is a example

#Minecraft server properties
#*************************
allow-nether=true
level-name=*****
enable-query=false
allow-flight=false
server-port=65534 <----------------------------------------------------- THIS RIGHT HERE NEEDS TO BE CHANGED!
level-type=DEFAULT
enable-rcon=false
level-seed=
server-ip=************
max-build-height=256
spawn-npcs=true
white-list=false
spawn-animals=true
snooper-enabled=true
texture-pack=
online-mode=false
pvp=true
difficulty=1
gamemode=0
max-players=20
spawn-monsters=true
generate-structures=true
view-distance=10
motd=**************

Why in gods name did you revive a 4 month dead thread?

All of you guys really helped me, so I wanted to thank you all very much. I changed the server port and now mine is working. Thank you!
