make kindle firmware use a proxy server

Nigovic · 08-01-2011, 12:36 AM

is there any means by which I could make the kindle firmware use a proxy server instead of directly connecting to internet. I'm a newbie in Linux, I searched for setting a proxy to be used by linux but I wanted to find out if anybody has a confirmed way of making the firmware (java app) use the proxy.

Any solution for this?

One option I can think on a K3 non-3G Kindle would be to re-define /opt/amazon/ebook/config/ServerConfig.conf:url.fints= but then you have the problem of convincing the Kindle that you are on 3G instead of WiFi so that the setting actually takes effect. Does anyone have suggestion?

Ok I did some digging... and it really seems there are NO provisions to enable a wifi proxy anywhere in the system. I spent a lot of time with ServerConfig.conf, trying to "brute-force" any sort of proxy directive that would effect wifi, to no avail. Ultimately I started picking apart the JARs, and found where I think the proxy parsing happens:

/opt/amazon/ebook/lib/framework-impl.jar, specifically com/amazon/ebook/framework/impl/device/h.class. Reviewing strings output shows all the obvious parameters from ServerConfig.conf... but really no wifi.proxy, *.proxy, proxy... anything... take effect.

So the only "simple" option would be to trick the Kindle into believing it is on 3G, which I have not yet figured out how to do.

Another option could be to re-compile the kernel (or just build the NAT modules) with "transparent proxy" support, redirect outgoing port 80 into a local proxy (privoxy or something like that) that can be configured for a parent proxy. Maybe in my free time... I would like my Kindle to be a better router...

another option might be to LD_PRELOAD a library that does this in userland, like tsocks. You would need to run the framework via tsocks then.
