1st - make sure he's using Tekkit. Not technic.

2nd - make sure your server and his tekkit are running the same version.

weve made sure hes using tekkit , we are using the same versions, he can join for about 5 secs but then he disconnects, other friends can join fine though.

I'm having the same problem. i can hear in-game sound briefly and then I crash. this is on a brand new map, on a server that I'm sure is the same version. I click "tekkit" on the launcher before logging in, and the issue is not resolved. I may have a different problem, as i have a 32 bit operating system, and i heard that you HAVE to have java 7 to play on a server (for whatever reason), while java 7 is only open to 64 bit systems.

P.S. : I can play technic perfectly fine.

ok i think we might of found the problem, 32 bit java on 64 bit computer would that do anything?

[freakachu]

yes, that would do a lot of bad things.

I am having a similar problem and it may be my own fault because i wanted my single player world to become a server.

First I was getting in and crashing right away.

So I took my SSP world and converted to to 2.1.1 with the converter thing and put it in my SMP world. I can run around for about 20 seconds or so and then it crashes. I have been tinkering with different settings for a while now and i can now log in for about 20 seconds before crashing.

I have tried changing the java from 7 to 6 and back and it made no difference.

I messed with the Ram settings.

I have tried fiddling with the actual map stuff itself to no avail.

No matter what I do it will log in and pretend its working then crash after a bit. No specific thing in the game causes it to crash (at first i thought opening a chest or falling).

(same settings now)

launcher version - 0.5.4.6

operating system - windows 7

java version - 7

server log from when he crashed - [iNFO] Connection reset

My problem still isn't solved. I have java 6 32x, running on windows xp 32x, and I crash upon join ANY public server, as well as my own.
