Disable Kindle Logging - Kindlesec.sh

The results from thorough research of the Kindle's back-end linux system has led us to believe that we have successfully identified the scripts that lab128 wrote for the remote backup of log files.

The files in question:
/usr/sbin/syslog-ng - syslog server and logging daemon
/usr/sbin/loginfo - pulls specific info from syslog
/usr/sbin/tinyrot - rotates log files to be pulled from remote servers
/usr/sbin/showlog - specifies which log file to send

The bash script simply links all these binaries to /dev/null rendering them useless. I have been using my Kindle 3 with no problems, I am able to email to my device and access the Amazon bookstore. This script will also work with the Kindle 3G, however it remains untested.

Requires Jailbroken Kindle with ssh/usbnetwork access.

Instructions:
1. Download the files - http://gitbrew.org/kindlesec/
2. Place kindlesec.sh on your Kindle via USB
3. mntroot rw
4. cd /mnt/us
5. ./kindlesec.sh

Enjoy your privacy.

If you have found this useful please donate.
We are hoping to raise enough to procure the latest Kindle model released with ads. If we can get access to one we will be able to create custom screensaver updates to replace them.

Let the research continue!

Congratulations! You managed to disable/break official/hack updates (un)installs for everyone you managed to lure into trying this ;D.

Hint: We kinda *need* the otaup script.

In the same vein, good luck not running out of space in the sys parts without tinyrot!

Aren't there a few steps missing?

1.1. Apply Existing jailbreak
1.2. Gain ssh/telnet access

NiLuJe: Actually, the logging functionality is disabled entirely, no logs are written to the log partition.

However, I have removed the line that disables otaup.

I've been running my kindle for a month with this script now and I have not had one single issue. Furthermore, the script creates a backup of all the bin files, you should look at it.

DiapDealer: I figured jailbreak and shell was a given, heh.

@dasmoover: Right, entirely missed the fact that you squished syslog-ng too, my bad .

As for the otaup script, that's one (slightly bruteforce-ish ^^) way of pleasing the 'no official updates plz' crowd, so you may want to keep that, just make it clear it will *completely* disable the 'Update Your Kindle' feature .

Anyway, apologies for the slightly snarky tone of my first message .

I execute the script both with putty and terminal of winSCP get an error on both:
Code:
/mnt/us$ ./kindlesec.sh 
Creating backup of loginfo, tinyrot, otaup, showlog, syslog-ng.
mkdir: cannot create directory '/mnt/us/.kindlesec/': File exists
cp: cannot create '/mnt/us/.kindlesec/syslog-ng': Operation not permitted

Pointing log scripts to /dev/null
the only difference from your description is on
Quote:

part. I transfered this file via ssh

( upto now did this script change "anything" on kindle?, if I couldn't manage to run in proper way, can it harm? )

Edit: Indeed, I couldn't install this properly then on the following restart my Kindle bricked.(I'm not 100% sure about the cause since I tried another one at the same time and it also did not function properly)
Thanks to the wonderful CS of Amazon I got a replacement even I said them the cause of the problem.

Hi there
has anyone tested kindlesec.sh on wifi+3G 3.2.X? At http://gitbrew.org/kindlesec/ it says kindlesec.sh is "Depreciated as of 06/04/11" - is this because it does not disable logging for newer versions?

Don't you just *hate* it when somebody 'deprecates' on you? (Sorry, mods -- I just couldn't help myself...)

syslog-ng, loginfo, and tinyrot are in /usr/sbin/, however showlog is in /usr/bin/ so it's clear the script is outdated.
At http://www.mobileread.com/forums/showthread.php?t=51371 I it's suggested to just change $NUMFILES and $ALLFILES in showlog - would this be this sufficient? If so, what was the point with kindlesec.sh? did it disable more logging than actually necessary?

Anyone found some other hacks for disabling logs sent to amazon?

I don't know WHY it was deprecated. The method they used in their script--of effectively removing all the scripts involved in the logging process (plus even the syslog binary)--is still valid. I have the same setup (with some additional modifications) on one of my kindles, from 3.2.1 to now 3.3 with no problems. Perhaps not having syslog was an issue for some in the hack community... I suppose if you rely on the whole debugOn thing, this would be a problem.

That said, I've run like this with no problems for ages and have had no use for syslog-ng running in the background. (It's an e-reader after all--I'm a linux sysadmin and I see no need for syslog to be running on my kindle.) Note: I only use launchpad, screensaver hack, kaffeine, & kinamp.

PS: I was sooo surprised when my 3.2.1 kindle didn't complain at all on the 3.3 update--I didn't roll back any of these changes before trying it.

I have changed in the script the location of showlog from /usr/sbin/ to /usr/bin/ and I can confirm that everything went fine.
After that I have installed some other hacks with debugOn and they seem to have worked, so apparently there is no issue with updates after turning logging off.

With logging off is it still possible for amazon to read and change stuff locally on your kindle?

A couple of (slightly unrelated) questions:
- Since all browsing traffic seems to be proxied through a server at amazon how can this be circumvented and connect e.g. through wi-fi directly using your own ISP (without going through the amazon proxy)?
- Has anyone found any hacks to connect to wifi and browse without the need to register for an amazon account?

So in answer to your question: when you go via Wifi it is not proxied AFAICT.

Well, I guess that is one thing to be said about a national, communications monopoly - its organized.

Takes me twice as long to reach google from here - -
But that is an artifact of various telecom companies buying each other out over time.

The "closest" google server to here is in the network hub on the grounds of the Dallas/Ft. Worth airport - -

The "original" provider of the network I have, has a network hub in the same facility - -
The "current" provider of the network I have, has a network hub in St. Louis (corporate headquarters town) - -

So a packet to the closest google server goes from here, to the "original" hub at DFW, where it is sent to the current owner's hub in St. Louis, where it is then directed back to the google server at DFW - -
Probably to the box on the next shelf of the server rack from where it started.
