LeoSat is a turtle operating system designed for remotely operated turtles floating at maximum height, serving as rednet nodes and GPS hosts simultaneously.
It includes a login system to prevent unauthorized users from using administrative commands.

List of commands to user over rednet:

• help: Returns basic info and list of commands (create a file called "help" and write something into it for custom help)
  
• ping: Returns PONG by default, returns location if GPS host is enabled
  
• pingmap: Returns a serialized table containing id, msg and distance of computers that answered a ping
  
• login <password>: Attempts to authenticate
  
• logout: Removes the current computer from the list of authenticated IDs
  
• up: Sends the turtle up into the sky, only works if there is enough fuel for traveling up and down, requires auth
  
• down: Sends the turtle back to the ground, requires auth
  
• reboot: Reboots the turtle, requires auth

The GPS host works similar to the built-in one, you can either provide coordinates manually or it will try to get them automatically from other hosts in range. You can also disable the feature manually.

I highly recommend changing the variable 'sPass' (at the top of the code) before starting leosat, otherwise anyone else who knows the default password will be able to hijack your turtle.

Examples:
leosat <x> <y> <z> uses these coordinates for the host
leosat false disables the GPS host and does not attempt to get the coordinates
leosat attempts to get the coordinates from other hosts in range, disables GPS host if unable to determine position

Download:
LeoSat:
pastebin get rjiYpE0r leosat

LeoSat without fuel check (for servers with infinite fuel enabled):
pastebin get YhkxJG4E leosat

Simple rednet console for testing to be executed on another computer:
pastebin get CFwBqJEv rednetconsole

Changelog
v1.4: Added "reboot" command, added automatic creation of startup file if none is found, made height variable
v1.3: Fixed logout crashing the program
v1.2: Made pingmap easier to read, you need a timeout higher than 2 on the client to receive the answer
v1.1: Fixed some minor bugs, apparently the maximum height a turtle can get to is 254 and not 255
v1.0: Initial release

ToDo

• Add rednet forwarding
  
• Create proper client

Feel free to give feedback and please report any bugs you encounter.

i made a similar program that integrated into my turtle swarm code
it could scramble gps and share the distances with every turtle in the network allowing you to track any id

you could also update the program in mid air

Do you mean allowing it to receive commands on it's way up or down?
I didn't allow that by purpose, it would mess up the GPS server and other turtles using it as reference point would get lost.

Hey Mind if I code along with you? I kinda want the experience.

Sorry, what do you mean?

[Budman17r]

Well I wanted to help with an item. I'll show you in a bit, its rudimentary but will help the GPS function better.

it has rcon and ftp

Oh, remote file access?
Maybe I should create a similar system too.

[Budman17r]

Hey Leo, Like I said I'm new at lua programming so the code sucks

I modified (and giving it to you) the up command added a 4th targ west or east, this makes the 2 west/east go down 3 after reaching the top, gets rid of the ambiguous cords

http://pastebin.com/B6ub2vHL

Let me know if you like it.

It also writes the startup file based on the targs, (and the new north/east/west/south targ (Only added East/west, did not code for north/south.

Thanks a lot, I integrated this partly, I'll try to release an updated version soon but I'll remove the y parameter completely and update the OP.

[Budman17r]

I'm honored. its no problem, I like what you have thus far, pretty damn sweet.

typo in the 1.4 adds an extra " to the else for writing to file

Ok, rewrote most of it, sorry for removing your code but you can now specify the height you want the turtle to get to.
Your idea of automatically writing a startup script is great though.

lol its no worries, I like the idea, been using them since I found it =)

You're welcome

[Leo Verto]

Ok, I updated the console, you can send messages to a certain computer only by starting it like this:

rednetconsole <id>

Using it without a parameter will broadcast messages.

Thanks to ChaddJackson12 for helping with the console and providing me a turtle and a computer to test it on Geevancraft.

[Leo Verto]

Added a version without fuel check.

I tested this program on Geevancraft and it seems to work great, except for that turtle that decided to shut down at y 254 (I had to tower up and down twice).
The startup file should be automatically created once you send the turtle up into the sky, it will launch leosat with the same parameters you entered before.

Doesn't Geevancraft have a super-long rednet range?

Either way, nice program. A simple way to automate a simple process, with a few extra bells and whistles.

It does have a very huge rednet range and I'm currently working on providing 24/7 global free rednet. Keeping your turtles close to max height also protects them from grievers.

I thought of adding a rednet forward/broadcast command, I might do that soon.

[amtra5]

Is it not possible to change the co-ods that are transmitted if the turtle is moving, thus not confusing any turtles. This could be done by writing the current coordinates in a file and changed when moving

[Leo Verto]

I'm currently working on an update for LeoSat allowing you to move around the turtles freely, my next goals are encrypted communication and support for your own networking handlers, so you can use LeoSat as a wrapper for them.

Are there any people still interested in this program?
