Could someone help me with server timeout.

[snapster1212]

Hi I'm snapster1212 and I want to host a semi-public tekkit server, but every time I leave the server batch thing running it times out after a while, is there anyway around this? (p.s. I don't want to use hosting people or something like that, just want to get my small tekkit server for a few people I met to play together, also if there's a better place for this just tell me.)
