Introduction
Sometimes you want scripts to be executed automatically when something happens, this article explains how to make sure scripts get executed at a certain point.
General Information
There are four different directories DD-WRT searches for scripts, these are
- /etc/config/
- /jffs/etc/config/
- /mmc/etc/config/
- /tmp/etc/config/
Script Types
You need to add an extension to the script if placed in one of the previous folders. Every extension has its own meaning.
Extension | Explanation |
.startup | will be executed on system startup, normally boot-time and before the firewall is configured. |
.prewall | will be executed whenever the WAN interface goes up and before the firewall. |
.wanup | will be executed whenever the WAN interface goes up and after the firewall. |
.if | will be executed whenever any interface goes up and after the firewall. |
.ipup | is run when PPP connection is reestablished after a disconnect and after the firewall. |
.ipdown | is run when a PPP connection has been shut down |
.sesbutton | is executed when the SES/AOSS/EZ-SETUP button is pressed |
Remember to change permissions on any script files using chmod to permit execution.
Execute Scripts with a Different Extension or in a Different Folder
If you want to execute scripts with a different extension or those that are located in an other folder you can create this script
for I in `/bin/ls /jffs/etc/config/*.myextension`;do sh $I & done
Of course you need to change the path (/jffs/etc/config) and the extension itself to match your desire.
How It Works
The command sh /jffs/etc/config/*.myextension will execute every script ending in .myextension found in the /jffs/etc/config directory. By setting this as the rc_startup value, your *.myextension scripts will load every time the router boots.[1]
