[Tekkit/CraftOS 1.3] Wanting to make a login system

Hello there,

I'm playing on a rather small Tekkit Classic server and I'd like to create a login-system for my house and its counterparts.

I was wondering how I could setup a database on a disk, connected to my server and access that through other computers.

Thanks in advance!

Well here's some APIs you should check out that will help you
- Rednet
- Fs

Do you have any current code? What is it you know and don't know?

I was thinking of doing something similar to this (This is Java code)

private void start() {
    System.out.prinln("Welcome to BLoginv1.0!");
    System.out.println("Please enter a command");
    String input = System.in.read();
    if (input.equals("login") | input.equals("Login")) {
	    login();
    } else if (input.equals("createUser") | input.equals("CreateUser")) {
	    createUser();
    } else if (input.equals("delUser") | input.equals("DelUser")) {
	    deluser();
    } else {
	    System.out.prinlt("Unknown command!");
	    Thread.sleep(3000);
	    start();
    }
}
private void login() {
    System.out.println("Please enter your username:");
    String in = System.in.read();
    BufferedReader reader = new BufferedReader(new InputStreamReader("<File>").getStream())));
    String line;
    while ((line = reader.ReadLine()) != null) {
	    if (line == in) {
		    System.out.prinln("Username is valid...");
		    password();
	    }
    }
}
private void password() {
}

And so on, if you get what I mean.

I just don't know how I could access files (if that's even a possibility) on a disk, and then access that disk, connected to a central computer, via rednet.

I'll check out the APIs. Any further assistance would be much appreciated. It's getting real annoying that everyone's just popping into my house when I don't want them to

Well if you want you could have it pretty simple, Something like this

-- Preventing CTRL + T --
os.pullEvent = os.pullEventRaw



local admin = {
    name = "<Admin Name>",
    pass  = "<Admin Pass>",
}




local function clear( color )
    if color ~= nil then
        term.setBackgroundColor( color )
    end
    term.clear()
    term.setCursorPos(1,1)
end

local function saveTable( file, table)
    local f = fs.open( shell.resolve( file ), "w")
    f.writeLine(textutils.serialize(table))
    f.close()
end

local function getTable( file )
    local f = fs.open( shell.resolve( file ), "r")
    local t = textutils.unserialize( f.readAll() )
    f.close()
    return t
end


local users = {}
if fs.exists(shell.resolve(".users")) then
    users = getTable(".users")
end


local function checkName( str )
    for i = 1,#users do
        if str == users[i].name then
            return true
        end
    end
    return false
end

local function checkPassword( str )
    for i = 1,#users do
        if str == users[i].pass then
            return true
        end
    end
    return false
end


while true do
clear()
print("Welcome to BLoginv1.0!")
print("\n\nCommands\nCreateUser | DelUser | Login")
write("Command: ")
local command = read()
if string.lower(command) == "createuser" then
    clear()
write("Admin: ")
    local name = read()
   if name == admin.name then
   write("\nPassword: ")
   local pass = read("*")
if pass == admin.pass then
   print("Success!")
sleep(.5)
clear()
   local nUser = {}
write("New User: ")
nUser.name = read()
write("Password: ")
nUser.pass = read("*")
table.insert(users, nUser)
saveTable(".users", users)
else
   print("Wrong password!")
end
else
   print("Wrong name!")
end

elseif string.lower(command) == "deluser" then
    clear()
write("Admin: ")
    local name = read()
   if name == admin.name then
   write("\nPassword: ")
   local pass = read("*")
if pass == admin.pass then
   print("Success!")
sleep(.5)
clear()
write("User: ")
local name = read()
for i = 1,#users do
   if string.lower(name) == string.lower(users[i].name) then
       table.remove(users, i)
   print("Successfully removed: " .. name)
os.pullEvent()
break
end
end
else
   print("Wrong password!")
end
else
   print("Wrong name!")
end

elseif string.lower(command) == "login" then
    clear()
    write("Username: ")
    local username = read()
    if checkName( username ) then
        write("\nPassword: ")
        local password = read("*")
        if checkPassword( password) then
            print("Successfully logged in!")
sleep(.5)
-- Do what you want when you're logged in here
        else
            print("Wrong password!")
            sleep(.5)
        end
    else
        print("No such user! D:")
        sleep(.5)
    end
end

end

Awesome, thanks!
Now all I have to do is get it to run off a server.
Luckily I have coding experience in C#, Java and VB :D/>
