OS: Linux Ubuntu Server 12.10


If you need anymore info ask me and ill post it for you.

 

are you hosting it in offline or online mode?

 

online mode

 

firewall off?

 

how do i do that i am hosting the server off of a Linux OS

 

Your pc have firewall that might block your server from checking players.



Oh W8 ... Did you buy minecraft acount or trying to connect from cracked launcher?

 

i allowed the port through "Inbound Rules" in Windows Firewall with Advanced Security

 

i also asked if you have premium acount or join by cracked minecraft.

 

im premium

im premium

 

paste your server properties

 

Code:

Any errors in your server log?

 

Perkun what do u think

 

Try reinstalling CraftBukkit. The newest Beta.

 

i still get the same error. i even tried force updating minecraft still nothing.

i looked at another forums and it says that session.minecraft.net is down.. when i typed it in it said Link appears to be broken..

 

Session servers could be down?

 

what is the session.servers is it my problem or Minecraft's problem? please help im really frustrated

 

RamsCraft the session server are the global mojang server that are responsible to authenticate you and your login if you start the game. You can check their availabilty via http://help.mojang.com

 

what does that mean?!?!?!?! please help!

 

Tell 8gigsofram he should close his Minecraft Launcher, and start it again, so that he gets a new session.

 

he did... we waited 2 days now... its so frustrating! how do i fix this problem!

we waited days now.. its VERY frustrating... if you need anymore info just ask and ill tell u

 

Your server is blocking calls to the mojang auth servers. Fix your firewall.

 

how do i fix it can u lead me through it please please please!

 

I have had this problem for well over 3 months and this entire time Iv been trying to figure out how to fix it, and Iv come to this conclusion: You screwed. There is no way to fix it.

 

What do you mean by fix how do you ive got that same error ive inserted my ports on firewall and have disabled firewall

 

You need to check your DNS servers - find out what is in /etc/resolv.conf - you may need to change them to something else like 8.8.8.8 & 8.8.4.4 (Google's DNS servers).
