Introduction
Sometimes you want script 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 it's own meaning.
Extension | Explanation |
.startup | will be executed on system startup, normally boot-time and: _before_ the firewall is configured |
.wanup | will be executed whenever an interface goes up (ex: ppp connection is reestablished after a disconnect, goes up first time) and: _after_ firewall stuff, so good ending for custom QoS and stuf. |
.if | will be executed whenever an interface goes up (ex: ppp connection is reestablished after a disconnect, goes up first time) and: _after_ firewall stuff, so good ending for custom QoS and stuff - .wanup - should be a better place for disconnect/reconnect events than the ones above |
.ipup | is run when ppp connection is reestablished after a disconnect, _after_ firewall stuff. |
.ipdown | is run when a ppp connection has been shut down |
.sesbutton | is executed when the SES/AOSS/EZ-SETUP button is pressed |
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.
