How to update Busybox on Router? (readonly filesystem)

loicloicloicloic · 02-26-2010, 09:41 PM

Hello everyone,

I am not sure if this is the right section for this question.

I have a Linksys WRT54G with the Tomato firmware on it.

So the system running on the router is Busybox 1.14., which as far as I know is Linux-based.

I want to update the busybox to the newest version, using ipkg which is the only package manager it has installed on it.

By the way, I use telnet to access the router.
So I use # ipkg install (the url to newest busybox release)

but at some point it stops and says:

mkdir: cannot create directory '//opt/usr/': Read-only file system

so what can I do? How can I make the filesystem read-write?

someone suggested on another forum that I download the latest busybox image, and install it on an emulator and then upload that to the router...I don't really know how to do that either..

Can anyone help ? That would be really helpful!

Thanks a lot,

Loic

Hello

I have DLink DSL-2640T Modem. I have installed the latest firmware V3.02B01T01.EU-A.20091107. After updating this firmware, the WDS option in the Advanced->Wireless Management was gone away. How can I enable it?

While I login to the router using telnet it shows me
BusyBox v0.61.pre (2009.11.07-07:14+0000) Built-in shell (ash)

While I navigate into /usr/www/html/advanced/wireless_mang_file.htm using telnet the WDS option was commented.
I want to edit the file /usr/www/html/advanced/wireless_mang_file.htm

While try to edit the file it throws the following error
Read-only file system
How can I edit this file?
How can I change this folder with READ-WRITE permission?

Regards
Rajan

check this page out:

http://www.dd-wrt.com/site/support/documentation

It gives instruction on how to update the image (search for "Router Database" and look for the one that matches your device) and flash into it.

Hello,

mount -n -o remount,rw /

With this command, you can convert read-only file system to read-write file system.

To change back read-only file system..

mount -n -o remount,ro /

Best regards

I did that. Doesn't work.

Code:

# pwd
/
# mount -n -o remount,rw /
#
# vi /www/admin-cifs.asp
...
"/www/admin-cifs.asp" Read-only file system
