- | | + | As mentioned above, kernels prior to 2.6.25 (2.6.2**4** with compat-wireless) are shipped with the softmac version of the driver which in its best day supports only half the functions, half the time. In other words, if you're stuck on an ancient kernel, you're pretty much out of luck. 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. |
- | At this point, the simplest method to bring up the new modules live is to reboot your system. | + | And if you're absolutely bent on installing the softmac driver on an old kernel, you can try [[http:// |

- | | + | |
- | + | ||
- | ===== Installing Fedora kernel headers and source ===== | + | |
- | + | ||
- | 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-beta2 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. | + | |
