Your best bet is to either install a supported kernel, or utilize one of the many Live CDs with pre-configured settings for aircrack-ng. |

- | | + | ==== Troubleshooting ==== |
- | | + | |
- | ===== Installing Fedora kernel headers and source ===== | + | === Couldn' |
- | + | ||
- | These instructions are specific to Fedora. Change **2.6.20-1.2944.fc6** to the particular kernel version you have installed. **uname -r** can help you | + | |
- | + | ||
- | You need these packages already installed: | + | |
- | kernel-headers-2.6.20-1.2944.fc6 | + | |
- | kernel-devel-2.6.20-1.2944.fc6 | + | |
- | + | ||
- | Running the command **rpm -qa | grep kernel** will show which kernel packages are installed. | + | |
- | + | ||
- | If the headers and development packages are not already installed then obtain them from your favourite repository then: | + | |
- | + | ||
- | rpm -ivh kernel-headers-2.6.20-1.2944.fc6.i386.rpm | + | |
- | rpm -ivh kernel-devel-2.6.20-1.2944.fc6.i686.rpm (obtain i586 or i686 depending on your architecture) | + | |
- | + | ||
- | Alternatively, | + | |
- | + | ||
- | Now download and install the full kernel sources if they are not already on your system (This assumes you have downloaded this RPM from your favourite repository). | + | |
- | + | ||
- | rpm -ivh kernel-2.6.20-1.2944.fc6.src.rpm | + | |
- | + | ||
- | Change to the following directory: | + | |
- | + | ||
- | cd / | + | |
- | + | ||
- | Change " | + | |
- | rpmbuild -bp --target=i586 kernel-2.6.spec | + | |
- | + | ||
- | **NOTE**: Change references to versions to your specific version in the next few lines. | + | |
- | + | ||
- | /bin/cp -a / | + | |
- | ln -s / | + | |
- | + | ||
- | ===== Recompiling Kernel with Loadable Modules ===== | + | |
- | + | ||
- | Some kernels incorporate the functionality built into the kernel. | + | |
- | + | ||
- | These are the settings for menuconfig using 2.6.20-gentoo-r7, | + | |
- | + | ||
- | First, change the appropriate items in menuconfig: | + | |
- | + | ||
- | cd / | + | |
- | + | ||
- | make menuconfig | + | |
- | + | ||
- | | + | |
- | then set | + | |
- | < | + | |
- | < | + | |
- | all other module capable IEEE 80211 items will have automatically set themselves to <M> | + | |
- | + | ||
- | Also check that: | + | |
- | | + | |
- | < | + | |
- | + | ||
- | Exit out and save the config | + | |
- | + | ||
- | Now apply the zd1211 and ieee80211 inject patches and recompile/ | + | |
- | + | ||
- | Apply the zd1211 inject and ieee80211 inject patches as per patch instructions but only do the 4 patch -Np1 commands, in gentoo doing the make commands and copying all the files is unnecessary!! | + | |
- | + | ||
- | After the patches are applied, you can now recompile the kernel and modules with the following commands: | + | |
- | + | ||
- | cd /usr/src | + | |
- | make all modules modules_install install | + | |
- | + | ||
- | Wait for it to finish and then reboot your system. | + | |
- | + | ||
- | Lastly, test your drivers and the injection patch. | + | |

- | + | ||
- | Also ensure that the time stamp on zd1211rw.ko module matches the date and time you compiled it. Otherwise this may mean you are running the wrong version of the module. | + | |
- | (Of course, you might also just update aircrack-ng to 1.0-rc1 or 1.0-svn, and use the unpatched mac80211 driver with it.) | + | |
- | + | ||
- | Note however, that starting with kernel v2.6.25, zd1211rw is only available in the new mac80211 flavor, so you need to use an updated aircrack-ng for it. | + | |
