 Posted: Sun Feb 20, 2005 10:34 pm Post subject: using QUERY_STRING in an exec command |
 |
|
Hi, I want to be able to use a query string in an exec command, so that if I type | Code: | | http://localhost/index.shtml?program.exe |
it will run program.exe. I tried | Code: | <!-- #exec cmd=&QUERY_STRING -->
<!-- #exec cmd=QUERY_STRING -->
<!-- #exec cmd="&QUERY_STRING" --> |
but none of them worked.
Thanks
Mike
PS: brilliant product! |

pallie,
These SSI directives aren't conforming to the standard directives supported by Abyss Web Server. That's why it doesn't work.
A script in PHP, Perl or any other scripting language can solve the problem. For example in PHP:
| Code: |
<?php
system($_SERVER['QUERY_STRING']);
?>
|
Of course, you should be careful with such a script/SSI page because it can open a security breach on your computer (it can be used to execute anything on your computer, adding a better security or some restrictions is a good idea.)

Thanks for your reply. I was hoping to do it without installing further components but I guess I'll need to.
Thanks for the warning - I want to be able to remotely run a program over my home network, for example to mute one PC by running a program on another. I have a script that will toggle the mute on the target PC, I want to be able to trigger it. I can do this by sending
<!-- #exec cmd="mute.exe"-->
but I have quite a few different things I want to do, for example volume up, volume down, next CD track so I thought I could have the program and parameters set dynamically from the URL such as
| Code: |
http://localhost/index.shtml?vol.exe up
http://localhost/index.shtml?vol.exe down
http://localhost/index.shtml?track.exe next
http://localhost/index.shtml?track.exe prev
|
I guess I could just have a different html file for each command I want - it only needs to be a one liner.
I'm assuming that as my LAN is behind a firewall, then it will not be possible for anyone outside to access it.

Do you want to control your computer remotely?

pallie,
If you don't want to install PHP and want to have security, we recommend creating for each remote action you want to perform a SSI page. For example:
| Code: |
<HTML>
<BODY>
I will run mute...
<!-- #exec cmd="mute.exe"-->
</BODY>
</HTML>
|
Put the above code in mute.shtml .
Create also vol.shtml and track-prev.shtml for example using the same template.
This way, there is no risk of executing anything except mute.exe (and other commands you've coded.) You also rely only on SSI.
