rcracki_mt has a new developer! James Nobis <quel> is making improvements on the *nix compatibility. So with the release of version 0.6.3 rcracki_mt now compiles and works fine on Linux (finally 64-bit as well!), MacOSX, OpenBSD, FreeBSD and NetBSD.
Please note that to compile under the BSDs you must use gmake.
I just released version 0.6 of rcracki_mt. This version is probably the latest beta version. Please report any bugs or problems you have in the (Bugs) tracker!
Also feel free to leave your wishes about new features or improvements.
