Teraku

But those are not planets and you can't get there from space and it doesnt lack air and its too magical and doesnt fit in a technical pack and is too complicated and im too lazy and pages are too expensive and symbols are too hard to find and its too dangerous and and and and because!!!

This is a bug in Galacticraft. If you don't use GC, you can simply remove it and this will be fixed.

Make sure none of you are on wireless.

Make sure the server and client builds match. The latest Tekkit version is 1.1.5, IIRC. Also, make sure you're running Tekkit.jar, not minecraft_server.jar.

Where's all the other planets?! I demand millions upon millions of planets, and I demand them right now!

I found a wiki at http://hexxit.wikia.com, it provides quite a bit of info. As for the "never seen before armor", that's Tribal, Thief and Warrior armor. They all give special bonuses, like Tribal giving a Jump Bonus, or Thief a speed bonus. Both of those also give Night Vision. Warrior armor gives you a lot of damage resistance from a lot of different damage types, IIRC.

Disable your firewall and anti-virus, and then try again. Forge is most likely missing some libraries that don't get downloaded in Tekkit Classic.

You'll also need an Item Tesseract at home. But yeah, you really only need one Tesseract per quarry.

The pack also simply wasn't meant to hold 30 players all exploring around. You need to prepare the Hexxit server for proper launch by pre-generating a pretty big area. Even so, the pack was meant to hold about 20 players at most.

I found a way to stop any kind of overflow permanently: AE and Logistics Pipes.

I tried to generate chunks and it started using CPU and RAM CANVOX WHY DON'T YOU FIX IT ALREADY GOSH

That IP is an external IP. It's not Class C or any of the known private IP's, anyway.

Because it's against the rules.

You might want to read the rules, just saying.

Disable your firewall and antivirus, and then try again.

There's a way around the Energy Loss. You'll need two Turtles: A regular Turtle, and a Wrench Turtle. First, fill up Redstone Energy Cells (Makeshift Energy Cells would probably work better due to the smaller amount of energy, if they can retain energy when wrenched). Next, have a Wrench Turtle dismantle the cell in order to have it retain its energy. Have the Wrench Turtle put the cell into an Item Tesseract. Lastly, put another Item Tesseract and a Chest down near the Quarry. Have a regular Turtle retrieve the Energy Cell from the Chest, and have it place the cell down next to the Quarry. Free lossless energy transport. Exploit-ish? Oh yes.

People will need Tekkit to join your server. It's not like it's a lot of trouble to just click on "Tekkit" and clicking "Launch".

Just a tip: You might want to read the rules.

Yeah, 25% isn't all that much. What matters most is that there's power being supplied, the amount doesn't matter.

Tekkit Classic.

If people keep dying in their own Pocket Dimensions and subsequently going to Limbo, then they're doing something wrong.

Meteors, most likely. If you can find where it struck, you can get some free ores IIRC.

Ah, wonderful.

Try disabling BitDefender and Windows Firewall entirely, and then try again.

If MystCraft makes it in, you can carry an Intra Linking Book around, I guess.
