nvram, nvram_x

[poz.]

I have a lama question to ask. I got a Asus 500g and I would like to do following changes 16_x_FIsFtpServer=0, wan_ifname=ppp0. I have used nvram set wan_ifname=ppp0; nvram commit. However, I still get old values after reboot. Can anyone tell me where I make a mistake? Is it hard coded somewhere without a change to change it?

Best regards

Hi,

I would like to know if every setting I can set up on Oleg's firmware is set in nvram value, and if so, is it possible to do a manual backup and restore.

I would like to go back from a mixed state configuration set and also to do a kind of configuration switch?

[Oleg]

Everything accessible via web interface is stored in the nvram.

[hugo]

but how can you make a backup restore in one operation? Do I have to script the nvram command, or can I use a /dev/mtd in some way?

[hugo]

after searching, there is some info about nvram_x, but this utility looked buggy and does'nt exist anymore. Do I have to script all value to save and restore nvram, or is there a new command to do so?

[Oleg]

Just use built-in save/restore configuration function. I think this should be enough for you.

[hugo]

yes, but it doesn't work on Wl-Hdd. I get a WLHDD.cfg file with 0k size.

On wl500 version (when I was testing it before your actual version for wl hdd), it was working.

Also, this method ask for a browser. I would need a telnet way, as I will be using non standard browsers.

Well, you can play dangerous game with nvram then:

cat /dev/mtd/3 > /tmp/nvram.bin

should backup whole nvram

flash /tmp/nvram.bin /dev/mtd/3
reboot

should bring it back.

Is there a command I can use to remove entries from nvram?

I have UPnP entries that have been storded to nvram that I would like to remove. I find them with this command:

nvram show | grep forward_port

I could of course reset to factory default, but I'd rather not...

nvram unset var_name

or smthg similar should work, I believe.

indeed that will work

also

nvram set var_name

should work to erase the entry

after doing this do a commit

nvram commit

[barsju]

Thx! That works, and now I'm working on a script like this:

#!/bin/sh
i=$1
while [ $i -le $2 ]
do
        nvram unset  port_forward$i
        i=$i + 1
done

but I keep getting

./clearUPnP: 8: +: not found

What gives??
