Ubuntu Linux: cannot find modules.dep.bin

By
While trying to load some kernel modules in one of my projects, I encounter the following errors:
root@ubuntu:~# modprobe carl9170
modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file '/lib/modules/3.10.17/modules.dep.bin'

and the following error:

modprobe: ERROR: ../libkmod/libkmod-index.c:821 index_mm_open() magic check fail: d00dfeed instead of b007f457

To solve this issue, run depmod
# depmod


From http://manpages.ubuntu.com/manpages/dapper/man8/depmod.8.html:
"depmod creates a list of module dependencies, by reading each module
under /lib/modules/version and determining what symbols it exports, and
what symbols it needs. By default this list is written to modules.dep
in the same directory. If filenames are given on the command line,
only those modules are examined (which is rarely useful, unless all
modules are listed)."

After running depmod, everything should work as expected.

BinDiff error: "Can't start disassembler. Please set correct path in the main settings first"

By
After installing  BinDiff  and running the application for the first time on my Windows 7 x64 machine, I tried comparing two different binaries but got an error in the middle of the process: Can't start disassembler. Please set correct path in the main settings first The solution for this error is very simple: While installing BinDiff, the installation process asks for the installation path of IDA. The default path (on x64 machine) would be C:\Program Files (x86)\IDA\. This is not always correct. At my case the installation was at C:\Program Files (x86)\IDA 6.3\. Moving the path inside BinDiff will not be sufficient since part of BinDiff's files are still on the old directory. Easiest way to fix it (or by doing it in advance): Uninstall BinDiff and install it while pointing to the correct IDA's path. -Tal

Ubuntu: Installing a missing ath3k firmware

By
While trying to prepare a new Ubuntu box to use a new card based on the Atheros chipset, I encounter the following error: Bluetooth: Firmware file "ath3k-1.fw" not found According to  http://wireless.kernel.org/en/users/Drivers/ath3k : ath3k is the Linux Bluetooth driver for Atheros AR3011/AR3012 Bluetooth chipsets. I saw this blog post: http://hexwave.blogspot.com/2011/04/debian-6-with-atheros-3011-ath3k-usb.html So I decided to try installing the package linux-firmware which contains the relevant file (I used  dlocate  to $ dlocate linux-firmware | grep -i ath3 linux-firmware: /lib/firmware/ath3k-1.fw or you can find it by searching for ath3k: $ dlocate ath3k-1.fw linux-firmware: /lib/firmware/ath3k-1.fw I just ran: # apt-get install linux-firmware and it fixed it by installing the missing firmware file. Good luck! Tal Kain

Compiling lsof for iOS device on Mac OSX

By
I started making a small research on my jailbroken iOS device and I was wondering which files does a specific process touches while I was using it. In order to do so, I wanted to use the famous lsof , so I downloaded the package from saurik's packages using Cydia, only to find out that the given lsof is not working on my device: lsof: PID 40 information error: Cannot allocate memory lsof: PID 39 information error: Cannot allocate memory lsof: PID 38 information error: Cannot allocate memory lsof: PID 37 information error: Cannot allocate memory lsof: PID 36 information error: Cannot allocate memory lsof: PID 35 information error: Cannot allocate memory lsof: PID 33 information error: Cannot allocate memory lsof: PID 31 information error: Cannot allocate memory After trying to figure it out, I decided that it would be the best to just try compiling my own lsof and use it on the device (I also liked the challenge :-) ) So my journey begins with downloading lsof from Apple'
