Hey i am figuring out how to lock specific files…

.. Well… now.. when running my startup script which turns the fs.isLocked to true then
when i try to edit a .@main@./uninstall then it says
Acces denied.. (Thats good.)
but… now it seems like it is still waiting for something, because when i type in "ls" (which is NOT locked) then it says:
File not found…


I have edited this code Thousands of times now, but still not working correct… can anyone explain me , why it says file not found?
This is the last edited code, so you can take this, and then tell me why and what to edit/modify…


code for the locker…

local attop = 0
local atdel = 0


local oldFsOpen = fs.open
local tArgs = {...}
fs.open = function(...)
tArgs = {...}
local lockFiles = {

end
end
if attop == tonumber(#lockFiles) then

else
atdel = atdel + 1
end
end
if atdel == tonumber(#lockFiles) then
atdel = 0
return oldFsDelete(unpack(tArgs1))
end
end

code for the startup file, which runs the locker, and then locks the files.

	   if fs.exists(".@main@./lock.op") then
		shell.run(".@main@./lock.op")

2 things: you have locals there, which makes the "oldFsOpen" zoomed into only that function. second, you're overwriting that variable in the start.

Even though you said ignore all the if tArgs[1] etc but do this to shorten it:

for i = 1, 27 do
    if tArgs[1] == lockFiles[i] then
        error("Access denied!\[er.num:4:\]", 3)
        term.clear()
    else
        return oldFsOpen(unpack(tArgs))
    end
end

and also, instead of that looooooooooooooooooooooooooooooooooooong line;

for i = 1,27 do
   if tArgs[1] = lockFiles[i] then
	 error("Access denied!\[er.num:4:\]", 3)
   end
end
return oldFsOpen(unpack(tArgs))

remiX, since you have a return directly after the check, it will actually only run 1 loop, because the return exits the function, so it would only check in lockFiles[1]

Yeah I didn't really look through the rest of the function, just wanted to show him that he can use a for loop instead of a long line

end

but when i type in "uninstall" then nothing happens.. and. if i type in anything ,,, then it just says File not found..


What?

Thanks:D

Where's the part for when you type in 'uninstall'? Or is the the Y/N part?

Edit: Oh it's in the other pastebin program…

well.. i still dont know why? the local-based stuff, in the lockFiles, should only be local, in the function. and when i run "uninstall" shortcut, then
it Acces Denied… (because the startup program locks it.)

i know you really want my full code, but i CANT do that. because last time i did that, i saw someone who stole it, and told everyone, it was himself, that did made it..
so i can only post some parts:

For one thing, I think it works with duplicated slashes. I could open //.@main@./Uninstall and get your uninstall program (can't test it right now though).

You need to remember that every time you override fs.open you could be overriding a previous override.
For example:
1. Startup runs, and overrides fs.open only unlocked filenames get through.
2. Uninstall shortcut runs, and overrides fs.open so only locked filenames get through.

Result: You can't open any files, because locked ones are caught by startup's override (throwing an error) and unlocked ones are caught by the uninstall shortcut's override (which acts like they don't exist)

Your uninstall shortcut's override doesn't return anything for unlocked files, which is what normally happens when a file doesn't exist. It sounds like that's a bug.

If you want to be able to bypass the first override (the one set in startup) then you'll need to make a way to tell it to stop blocking locked files.

you cant open with double slashes, (i have tested)..



and i want to bypass.. but if i should … hey wait a min… i could make a ´file called "Lock.op" then when i run it i need a argument, which would be True, or False.. if true then it will Lock ALL the files in the Lock program, and if False, then the opposite.. am i right on this?

i will try to make that, and then post back if worked, or not.



Thanks..

Well.. now i've made this file: (called "lock.op") i hope this would work
EDIT2: edited to newer code. but when i run ".@main@./lock.op false" and then run anything it just diplays Acces denied, press any key to continue…

am i right on this code? (just so i can be sure, not to edit everything, if i dont have to…)


EDIT: Well. in CCEMU it works, when locking… but now i cant unlock files? :o/> ehhm?

Well, first the tArgs needs to be outside the function, or it will get the arguments to the function instead of the arguments to the program.
Second, each time you run Lock.op it still just adds another layer. You need to override the function once and make the override check something else (for example fs.isLocked, then you can set that to true or false)

Well..right now im totally lost…. well..
my tArgs inside the function is now outside. ( at the top )

should i then make a new

local tArgs = {...}
local oldFsLock = fs.open
fs.isLocked = function(...) -- now i dont know what i should do...

my code right now is:

edit: i edited the same code, but now it works fine…
i type in.
>.@main@./Lock.op true
> edit startup
Bios:358: Acces denied![er.num1]
> .@main@./Lock.op false
> edit startup – now when i run this… the screen turns off, ( i could not see any errors, because it was turning off to quick, after showing error.. (IF it was an error))

i know you should not make the code for me, but can you give a little example on the fs.isLocked? i dont know where to start..

Thanks :)/>

Oops, forget the tArgs bit. I misread your code and thought tArgs was trying to do what tArgsI does.

What I mean by using a variable like fs.isLocked:
Run this once:

local oldFsOpen = fs.open
fs.open = function(...)
local lockFiles = {
<list of locked files here>
}
-- if fs.isLocked is false, allow ANY file
if not fs.isLocked then
return oldFsOpen(unpack(tArgs))
end
if tArgs[1] == lockFiles[1] or tArgs[1] == lockFiles[2] or tArgs[1] == lockFiles[3] or tArgs[1] == lockFiles[4] or tArgs[1] == lockFiles[5] or tArgs[1] == lockFiles[6] or tArgs[1] == lockFiles[7] or tArgs[1] == lockFiles[8] or tArgs[1] == lockFiles[9] or tArgs[1] == lockFiles[10] or tArgs[1] == lockFiles[11] or tArgs[1] == lockFiles[12] or tArgs[1] == lockFiles[13] or tArgs[1] == lockFiles[14] or tArgs[1] == lockFiles[15] or tArgs[1] == lockFiles[16] or tArgs[1] == lockFiles[17] or tArgs[1] == lockFiles[18] or tArgs[1] == lockFiles[19] or tArgs[1] == lockFiles[20] or tArgs[1] == lockFiles[21] or tArgs[1] == lockFiles[22] or tArgs[1] == lockFiles[23] or tArgs[1] == lockFiles[24] or tArgs[1] == lockFiles[25] or tArgs[1] == lockFiles[26] or tArgs[1] == lockFiles[27] then
error("Access denied!\[er.num:1:\]", 3)
else
return oldFsOpen(unpack(tArgs))
end
end

fs.isLocked = true

To lock:

fs.isLocked = true

To unlock:

fs.isLocked = false

This works because there's only one override. The problem you have before is that every time you override a function that way, it gets "layered" on top of any previous ones and doesn't know about the real fs.open, and so the previous overrides are still there.

Thank you Immibis! That worked out fine (Sry for late answer but i couldnt test, before now. )

Keep working :D/>

to admins… could this topic be deleted, since it contains some codes that noone else, may see.. (its used in AdvLock which may not be seen, so hackers cant kill the program)…

There's nothing you can do to prevent the code getting into their hands if you use it at all, anywhere, ever, so the only thing deleting the topic would do is prevent other people from being able to find the answer if they have a similar question.

yeah.. but. may i then edit the codes, for the parts, they may NOT see?
and, immibis?

on that code… can i then do it, so only if you type in "EDIT test" it will prevent.. but then if you just type in "test" then it wont prevent that… i somehow know that i think that it is the fs.isReadOnly() but not sure….

Really, you should just have a client program that receives the program over rednet (for security, you send a program that rewrites the startup as the current client, deletes everything else on the computer, reboots the computer, and then receives your super-secret program and runs it without ever storing it to disk…but even that can be beaten by a smart hacker).

Ehm. I actually dont know why you would receive the program over rednet.
But with this, i will just do it harder to hack/delete

So that the user doesn't have access to a computer that contains the program file, of course. If the program is stored on a file on the computer they can reach, they can place a drive with a steal-everything-on-the-computer startup floppy. Then they can dissect your secrets at their leisure.

yeah but how can I prevent that? well.. if i should make a client, then it would be easy just to delete that, and then put virusses into the computer… only if CC get the PREVENT disk boot, thing, into the CC mod, THEN i can prevent, that… else i cannot prevent anything that has any usage of a disk drive… :(/> (but it would be great if we would be able to prevent disk booting )

Or better yet, they come here to the forum and download his code and read it. done. no writing of programs, just download and open.

Like I said, you prevent (or at least deter it) by not having anything stored on the computer they can access except for the client that downloads the program over rednet and runs it using loadstring rather than having it as a file on the computer. Then you use a two step download, the first rewrites the client to be the correct version, the second is the actual program you're trying to keep secret.

You can make it difficult enough to hack so that anyone able to hack it probably already has samples of the code you're trying to protect. Which is to say, as difficult to hack as there is any point making it.

Probably more so, really.

Well.. i just found a fail/bug when i tried to edit something in a dir. and then i CAN do it… but i told "lock.op" to lock .@main@./uninstall but it doesnt…

Spoiler

	 
	 
	local oldFsOpen = fs.open
	local tArgs = {...}
	fs.open = function(...)
	tArgs = {...}

	return oldFsOpen(unpack(tArgs))
	end
	for j = 1, #lockFiles do
	if tArgs[1] == lockFiles[j] then
	error("Access denied! \n\[err.Num:1:\]", 3)
	else
	return oldFsOpen(unpack(tArgs))

	error("Access denied! \n\[err.Num:1:\]", 2)
	else
	return oldDelete(unpack(tArgs1))
	end
	end
	end

and in startup i run this:


	if fs.exists(".@main@./lock.op") then
	shell.run(".@main@./lock.op")
	fs.isLocked = true
	end


but when i did that, i can still edit / delete programs in the dir .@main@.

please help me out of this problem :(/>

(quick: when everything works fine, and i type in "edit .@main@./uninstall" it says Acces denied (which is good) but.. when i enter something else ( a program like "ls" or "list" or "dir") then it just say
File not Found..


Please help…
Thanks in advance
