Cisco L3 & L2 IOU on Fedora Linux [Hacked]
Note: This is for educational purpose only.
These steps are based on tutorial "Defeating Cisco IOU’s License Protection" and are adapted for Fedora Linux. After the video from you-tube was deleted the creator of video made the "patch" which you can check here.
Please, consider using IOU – it is meant for internal use only thus it is probably illegal to use in case you are not Cisco employee or partner. For further information about licensing, please visit this site. http://evilrouters.net/2011/01/18/cisco-iou-faq/

[How To] - Troubleshoot GNS3 Qemu
Many
GNS3 users use Qemu emulator to run various network OS installed on Qemu images
– for example Olive, ASA, Vyatta and many others. Some users complain about not
having a network connections between these devices or a console window appears
and disappears after the short time. In both cases Qemu hosts are not started
properly and Qemu images don’t work.
This issues are typically caused by entering a wrong parameter in GNS3 setting. For instance when user checks a box “Use kvm” in GNS3 settings and CPU doesn’t support kvm or kvm is not enabled in BIOS, it ends with warning message “unknown parameter kvm” and Qemu image is not started. Please remember that kvm is not supported by Windows so you shouldn’t have “Use kvm” checked if GNS3 is installed on Windows.
Another issue mainly occurs on Linux and Mac OS and it is caused by using unpatched Qemu binary. GNS3 create UDP tunnels in order to make connection between Qemu devices and that is why Qemu source have to be patched for UDP tunnels, compiled and installed by user. Although many Linux distributions already have Qemu installed in /usr/bin/ directory, this version of Qemu is unlikely to be patched for UDP tunnels. For this reason the Qemu doesn’t understand parameter -net type udp and it is halted after its start.
As long as patched Qemu binary is included in GNS3 all-in-one package, the Windows users don’t need to patch, compile and install Qemu by themselves.
Except of the wrong parameters I have already mentioned there can be another problems which prevent Qemu starting successfully. If you find Qemu difficult to start you should consider to do following troubleshooting to find out the reasons why Qemu doesn’t work.

iPhone 5 Jailbreak - [Update]
Yes you read that right! iPhone 5 has been jailbroken successfully on the launch day! Popular and respected iPhone developer chpwn tweeted a picture of his iPhone 5’s homescreen with Cydia icon on it in full 1136 x 640 resolution glory (the same res. as iPhone 5).
iOS 6 Jailbreak Using Redsn0w [Step By Step Guide] - (iPhone & iPod touch - A4-Based Only)
As is usually the case when this time comes around, jailbreakers have been waiting patiently for the official word on whether it is safe to update their devices to iOS 6 or not. Although Apple have taken some design and functionality inspiration from a number of Cydia based tweaks and offerings, the hardcore jailbreak faithful still need to experience that freedom on their hardware.
iPhone Dev-Team’s Redsn0w tethered jailbreak works on today’s final iOS 6 release. Follow the simple steps below to jailbreak iOS 6 using the latest version of the iPhone Dev Team’s Redsn0w tool.
Before going through any jailbreak process it is always good housekeeping to perform a full backup of all information on the device. It is unlikely that anything will go wrong during the process but when undertaking any process that modifies the internals of a file system it is always prudent to err on the side of caution.
