Hi, aircrack-ptw [1] can safly be removed. The ptw method is included in aircrack-ng. Aircrack-ptw is unmaintained for years now. In addition, it's not available on the official homepage anymore. Just clicked through all those madwifi packages. As ath5k superseded madwifi (and is actually included in the kernel), couldn't most of the orphaned and/or out-of-date madwifi-X packages be removed? It's just a suggestion, though. In detail: dkms-madwifi https://aur.archlinux.org/packages.php?ID=11662 madwifi-aircrack-tp https://aur.archlinux.org/packages.php?ID=17049 It's orphaned, depends on already removed packages (kernel26tp), thus unusable. madwifi-aircrack https://aur.archlinux.org/packages.php?ID=33076 (same) madwifi-hal https://aur.archlinux.org/packages.php?ID=20857 (depends on kernel26 ...) madwifi-hal-svn https://aur.archlinux.org/packages.php?ID=20963 madwifi-svn-hal https://aur.archlinux.org/packages.php?ID=20221 madwifi-ice https://aur.archlinux.org/packages.php?ID=23472 (depends on removed packages, kernel26, ...) Happy removing ;) Regards, Max [1] https://aur.archlinux.org/packages.php?ID=18331
