How to update Busybox on Router? (readonly filesystem)

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

Can anyone help out?
Thanks

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.

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