I read this article on Nezzen.net that says that you can make a web-server on your router providing that you rewrite its firmware with a free DD-WRT, Tomato, or equivalent.
Leaving apart the fact there is no DD-WRT available for my router, I don't know if I would change the firmware.
Is it possible to make
httpd run as a minimalist webserver without changing the firmware? This might mean that I need to have a file system in the RAM memory. I try to
cat something >file I see the filesystem is obviously read-only, but it should have some writable parts, somewhere it needs to keep its settings!
If I connect with telnet to the router I see it already has in
/home/httpd/web/ has some html files but the filesystem is read-only.
The router is Sitecom WLM 2501.
