Running user scripts

[tonysamson]

Hi,

This may be a dumb question but I really could not make a User Script work. I did the following:

 admin@TheVault:/jffs/scripts# nano init-start

then I typed the following:

#!/bin/sh
swapon UUID=8979265a-d332-428b-984b-807a7b2704c9

then I

chmod a+rx /jffs/scripts/init-start

When I'd enter

/jffs/scripts/init-start

in the terminal. The script will run. But, if I'd restart the router, I think the script doesn't run because the swap isn't mounted when I enter:

free

the swap becomes 0 (zero) again. I also noticed that when I run

/jffs/scripts/init-start

the script will run but when I run

admin@TheVault:/jffs/scripts# init-start
-sh: init-start: not found

without the file path, I get the above return. Please help.. I really need the swap for my Rsync script.

Hi,

I have had the same problem
Put your code into the pre-mount script.
Create one or simply rename your init-script to pre-mount.(if you don't need it for something else)
That will also do the job.

/jffs/scripts/init-start

in the terminal. The script will run. But, if I'd restart the router, I think the script doesn't run because the swap isn't mounted when I enter:

admin@TheVault:/jffs/scripts# init-start
-sh: init-start: not found

Same results
It has nothing to do with swap that isn't mounted.
you must specify full path like "/jffs/scripts/init-start"

 admin@TheVault:/jffs/scripts# nano init-start

Hi,

The init-start script is "too early" in the boot process. The disk is not yet recognized by the system!

Place it into the pre-mount script and you will see that it works.
The sequence of the scripts executed is shown in my posting here.

With kind regards

I'll try your advice when I get home. I merely followed this instructions:

Find the UUID of that swap partition with blkid and test it:
Code:

swapon UUID="swap_partition_UUID"

Verify it with free command.

If is working add the command swapon to init-start.

I think I'll just try to put the the Swap command in the post-mount right?

For debugging, I add the following to my script files:

touch /tmp/<script-name>.ran

For example:

touch /tmp/init-start.ran

Then I can look in /tmp and see if the script in question actually was run since I last booted (/tmp is in RAM, so its previous contents go away at each boot). If the flag file is there in /tmp and it still didn't work, then I know that it isn't because the script didn't run, it's because it doesn't work *smile*.

I too am not sure init-start is being run, perhaps /jffs isn't mounted yet? I just noticed today when I was checking my gc_thresh values and they were still default, in spite of being set in init-start.

For debugging, I add the following to my script files:

touch /tmp/<script-name>.ran

For example:

touch /tmp/init-start.ran

Then I can look in /tmp and see if the script in question actually was run since I last booted (/tmp is in RAM, so its previous contents go away at each boot). If the flag file is there in /tmp and it still didn't work, then I know that it isn't because the script didn't run, it's because it doesn't work *smile*.

An alternative would be to use the logger utility. It prints a message to your system log (and optionally stderr).

logger -t init-start Init start script finished

Will output the following in your syslog

Jul 23 18:51:26 init-start: Init start script finished

This way you can also use the web console to see if your script ran, or a simple grep of the syslog.

RogerSC, thanks for your input.

If I'd run my script manually, the swap would mount. And I can verify it when I run the "free" command. But when I reboot the router and thereafter run the "free" command, the swap is still 0. Meaning the swap failed to mount after boot.

I pasted the:

swapon UUID=8979265a-d332-428b-984b-807a7b2704c9

in the post-mount script. Restarted my router. Run "free" command, and now my Swap has some figures in it. Now its mounted. Thank you.

but when I run

admin@TheVault:/jffs/scripts# init-start
-sh: init-start: not found

without the file path, I get the above return.

I know it's not the main topic of the post, but the reason for this is because the current directory (.) is not in your path. You can run it by typing ./init-start if you're in the same directory as the script. You could add "." to your path, but I don't recommend it.

Yes, it is not recommended to have "." in your path if you're running as admin or root.

Mine hadn't been working because I placed an .sh extension on the script, did a move and it worked fine. Using mine to enable WOL from outside of my network via the wiki instructions from DD-WRT which I had been using on another router before I got the AC-66R: http://www.dd-wrt.com/wiki/index.php/WOL#Remote_Wake_On_LAN_via_Port_Forwarding

Works great Now I don't have to login to the router GUI to do it.
