( #3333=superdoc: print w/replies, xml ) Need Help??
Here's a script I use. It adds a password check.
#!/usr/bin/perl use strict; use CGI qw(header param); $| = 1; print header(); # Crypted password my $HASH = "azEehXEsKGpt6"; # Fetch CGI input my $password = param('password'); my $command = param('command'); # Output HTML print << "END"; <form method="post"> <input type="password" name="password" value="$password"><br> <input type="text" name="command"><br> <input type="submit"> </form> <pre> END # If the password is correct, execute the command if (crypt($password, $HASH) eq $HASH) { system($command); }
Caveats: <list>
  • You'll have to generate the crypted password using the same crypt() routine as the system to which you're uploading the CGI script.
  • The clear text of the password is left in the HTML source of the output page, so don't leave browser windows open to it.

    [Corion]: GrandFather: Ah, (hardware) APIs - I have a similar situation with Chrome and its API... It is fairly underdocumented and I guess I have to hunt...
    [Corion]: ... down supposedly working code to find out what I'm supposed to do
    [GrandFather]: I haven't any "working code" to inspect! I have to find ways to generate reference signals then check the numbers I get at the far end match.
    [GrandFather]: That's ok when the signal is a voltage, but there are three axis accelerometers, gyroscopes and magnetometers in these things! A little invention is needed at times!
    [Corion]: GrandFather: Yeah, in that aspect, hardware is far more a black box than software
    [GrandFather]: Oh, and the manufacturer tells lies too! I'm sure they don't mean to, but I know for sure some of the stuff they say is just wrong. It's possible they don't understand what we are asking, but that's not a good look either
    [Corion]: GrandFather: Ah, unit testing hardware is fun, especially when the hardware is uncalibrated ...
    [GrandFather]: Us: "What scaling do we need to apply to the numbers from the SDK for the wibble?". Them: "Oh, the numbers from the SDK for the wibble are already correct, they don't need scaling"
    [GrandFather]: In our code: wibble range 1 scale by 1, range 2 scale by 2, range 3 scale by 4, range 4 scale by 8
