[ fixed channel mon0: -1 ] Issue

The new kernel 2.6.35-25 has issues when wireless cards are put into monitor mode. To check the current kernel version on your system use the "uname -r" command and that would display the current kernel. For example if you use airodump-ng it would say "fixed channel mon0: -1" like seen in the screen-shot below.

 














This Saturday I will show step by step to solve the "fixed channel mon0: -1". Why is this a big issue, this affects other applications that require monitor mode such as Kismet which also means when a user want to do a packet injection the card can't provide that function. On the tutorial for this Friday I will show you how to patch this problem with a Atheros wireless card.

The following Linux Distro's have 2.6.35-25 kernel

  • Ubuntu 10.04
  • Ubuntu 10.10
  • Backtrack 4 R4
  • Any other Linux distro that is keep up to date.
If your still using previous versions of Ubuntu or BackTrack then this does not affect you, but if you have upgrade your kernel then it might.

Netwars Competition

The NetWars game is a collection of computer and network security challenges. It is designed to represent real-world security issues: their flaws and their resolutions. Each player can follow an independent path based on individual problem solving skills, technical skills, aptitude, and creativity. The game is played in a fun but safe environment using the technology that drives our lives every day. The game starts when a player downloads and starts a CD-ROM image on a PC or in a virtual environment such as VMware Player. The image contains a brief tutorial and the game's full instructions. The player must find a hidden key within the image that is downloaded and then uses that key to enter an online environment where knowledge of security vulnerabilities and their exploits can be turned into points. Upcoming Competitions   June 18-20, 2010 PST September 17-19, 2010 November 5-7, 2010 December 17-19, 2010 April 29 - May 1, 2011 Click Here to read more

Protecting the Kernel

Standard Linux Kernel When installing Linux it comes with the default Linux kernel compiled which is okay for most user, but when it comes to protect your data it is also good idea to build your own secure configuration. To get latest state or beta version of the kernel go to http://www.kernel.org/ Note: if you’re still unsure or feel uneasy if you want to do this then this is not for you. To get full details on compiling Linux Kernel you can visit: http://www.digitalhermit.com/linux/Kernel-Build-HOWTO.html#CONFIGURATION-INTRO http://www.faqs.org/docs/Linux-HOWTO/Kernel-HOWTO.html For security reason the DTS server kernel configuration can not be shown.
