ADB over TCP

To make ADB work in iMX51 using TCP:

*In your host machine:

- Install android SDK
- set ADBHOST=BOARD_IP (setenv ADBHOST=xxx.xxx.xxx.xxx)
- adb kill-server

*In your board:

- make sure that  ro.secure property is *not* set when the adbd daemon is launched, so edit the file default.prop
- make sure that /dev/android_adb or /dev/android do *not* exist
- stop adbd
- start adbd

Now you will be able to list the device:

hamilton@saygon:/opt/work/androidsdk/android-sdk-linux_86/tools$ ./adb kill-server
hamilton@saygon:/opt/work/androidsdk/android-sdk-linux_86/tools$ ./adb devices
* daemon not running. starting it now *
* daemon started successfully *

Garanto que é mais eficaz do que ficar postanto comentários nos blogs, isso pelo menos ajuda a colocar esses péssimos provedores de serviços em um ranking. Tudo bem que a Anatel pouco faz, porém se podemos infernizá-los… não podemos deixar essa oportunidade de lado.

DJBDNS security patch

Source http://marc.info/?l=djbdns&m=123613000920446&w=2

If the administrator of example.com publishes the example.com DNS data
through tinydns and axfrdns, and includes data for sub.example.com
transferred from an untrusted third party, then that third party can
control cache entries for example.com, not just sub.example.com. This is
the result of a bug in djbdns pointed out by Matthew Dempsky. (In short,
axfrdns compresses some outgoing DNS packets incorrectly.)

Even though this bug affects very few users, it is a violation of the
expected security policy in a reasonable situation, so it is a security
hole in djbdns. Third-party DNS service is discouraged in the djbdns
documentation but is nevertheless supported. Dempsky is hereby awarded
$1000.

The next release of djbdns will be backed by a new security guarantee.
In the meantime, if any users are in the situation described above,
those users are advised to apply Dempsky's patch and requested to accept
my apologies. The patch is also recommended for other users; it corrects
the bug without any side effects. A copy of the patch appears below.
