^ Never mind, I figured it out. Thanks again, guys.

Where has WinSCP been all my life? I can edit files on the router using full-blown GVim instead of cruddy router vi! Woot!

 

[snakebite3]

It's a quirk of the SMB implementation that it doesn't see the top level directory (there may have been a workaround in one the threads, I can't quite remember). If you change the access to Guest Mode, it will then show up.

But @Martineau has the right answer....it's what I use when working on the code...I can edit things directly out of WinSCP and it stays in the right format.

What protocol should I be using?

^ Never mind, I figured it out. Thanks again, guys.

What's the solution?

Looking at the resulting V18 restore script, is the dhcp_staticlist gone? I thought you needed the custom list and the static list both?

Thanks for the report...when there is a number version of a variable (dhcp1_staticlist which is included in the ini) usually the base variable without the '1' is used only by the web gui. I just ran a test case for 'staticlist' and that doesn't appear to be the case here. I'll get a refresh out later today.

Enable Samba on the router and use the SCP protocol in WinSCP.

Sorry for the quick update...but thanks to @elorimer for catching my error!

Hi Guys

I have been trying to get this script to run as a cron job and keep running into a specific issue.

Cron is created via /jffs/scripts/services-start, with the following:

/usr/sbin/cru a Backup "45 14 * * * /mnt/ASUS/backup/nvram-save.sh"

Now the issue that I seem to be having is it is not seeing, or finding, the nvram-merlin.ini file, although all files are within the same folder.

The syslog outputs the following when running the cron job:

Jul 2 14:45:02 nvram-save.sh: NVRAM User Save Utility - Version 19
Jul 2 14:45:02 nvram-save.sh: NVRAM variable file not found: nvram-merlin.ini

Can someone point me in the right direction in solving this issue, if at all possible.

Thanks for your expert advice.

 

[john9527]

Things may be getting confused....the 'backup' folder has a special meaning in the program to only hold the generated data files as a subfolder to the folder with the executables.

Normal setup would be
/mnt/ASUS = all .sh files and the ini
/mnt/ASUS/backup = the generated save files

So, if you want everything in one folder, put everything in /mnt/ASUS (or any folder name that you would like, the scripts should be smart enough to run from any parent folder....except one named backup.

 

[Pos22]

Thanks for your reply John

I moved the files as suggested and changed the cron job to reflect the changes:

/mnt/ASUS = all .sh files + the ini

Cron job now is as follows:

/usr/sbin/cru a Backup "30 15 * * * /mnt/ASUS/nvram-save.sh"

Now I am still seeing the same issue:

Jul 2 15:30:01 nvram-save.sh: NVRAM User Save Utility - Version 19
Jul 2 15:30:02 nvram-save.sh: Saving settings from firmware 378.55_alpha2-gb735668
Jul 2 15:30:02 nvram-save.sh: NVRAM variable file not found: nvram-merlin.ini

The cron is running, but the script seems to not be running because it cannot see the ini file, although it is on the USB root folder with all the .sh files.

As you can see, I am testing the alpha version of merlins firmware, would you think this would be the issue?

Sorry for the fire drill.....you could move all the code to another folder, but it didn't handle being executed when it wasn't in the current working directory. I've attached an updated script (rename it from .sh.txt to just .sh and replace your current version). I'll put this change in the next release, as well as make the same change for the rest of the scripts.

I just wanted to drop by to say that you are brilliant!

Thanks John

I shall try this later today when I get home.

Just subscribed to say awesome job and thanks @john9527. I wasn't aware of this until I did a little searching, so was holding off updating, glad I did now !

Works perfectly, Thanks.

P.S: I should also mention, I am running an AC68U, and had to dial back the OC to 800,666 or it would just hang with WAN/LAN and power lights on (all other lights OFF), after dialing it back to 800,666 I don't have any issue's running the scripts, so you may want to edit the OP with this info, just incase it effects other users?

Don't know what to say about that one....I run AC68 overclocked to 1200,800 and have never run into a problem with the scripts. I'd keep an eye out for any strange behavior during normal running...some routers just can't be overclocked successfully.

Yeah I find it very strange.

Only because it has been OC'd (1200,800) for months (in fact I believe I OC'd it the day I purchased it, so it would be longer than 12 months ago??), and have had no issue's with it ever - until I put some scripts onto it, so I have solved both issue's here (well credit goes to yourself for this script and the cron issue), just thought I would let you know, in case someone else comes up with the 3 lights ONLY issue (WAN/LAN/Power).

I had gone through all the usual rule out everything first, because I had recently put everything onto a USB 3.0 flash drive, so I removed the 3.0 and put the scripts onto a 2.0, same problem, if I removed the USB flash altogether the issue disappeared. Finally narrowing down to the OC, and when I dialed it back, it could survive a reboot just fine (after the initial reboot from restoring the settings, and the manual reboot after restoring jffs), any reboots after that, it would suffer from the WAN/LAN/Power light issue.

Now it is not OC'd and back at 800,666 I have no issue's at all, and I dont have the 3 lights issue after rebooting. So all is good.

Like you say, some routers just can't handle OC'ing, and mine would be one of them. This is no issue to me at all, it's not really gaining anything by the OC, so it is not bothering me in the slightest.

Just want to personally say Thanks, this script saves me so much time, if it was not for this script, I would be working on my router for a day or two after every update.

Hi,

Some AC68U have issues to overclock the RAM above 666 MHz (incl. mine).
I have now CPU on 1200 MHz without problems. But increasing RAM clock leads to stability issues.

With kind regards
Joe

Hopefully I have understood correctly and its OK to post a new question about the nvram utility here; if not, would appreciate a sign post. Thanks to the dev who came up with this nifty utility.

Like other posters, I am hoping this utility will lower my barrier to staying up to date with the wonderful Merlin firmware. My problem is that I seem to be getting a slew of permission errors both before and after changing the admin user ID to "admin". So am I alone in seeing these errors? Is the process working anyway and I can carry on with reasonable confidence that the restore will work?

Output from router putty session showing the errors is below.

Thanks and regards,
Chris

You are in the right place

Haven't seen this one before. You mention 'changing the userid to admin'....did you copy the program files over where the admin username was changed to something else?

Please post the output of

ls -l /mnt/ASUS (those are small letter 'L')

so we can see the owner and group of the files.
