I am running the John that comes with Fedora 22, the docs cay it is 1.10 2013/05/29. I'm not sure this 1.10 version of JtR exists. It probably should be 1.8.x. 2013 sounds a bit old, you might want to install a more current version, and even to compile a Jumbo version. > John has been crunching away for 20 days on a Lenovo x120e notebook without finding the password. Well I know a few things about this password and I would like to instruct John o be selective on what it tries. But I am a bit of a hack and need so hand-holding on how to alter /etc/john.conf (or make another) that will target the password. > > I know the password is 10 characters long. > > I know that the first position is either 'x' or 'X'. > The second is a digit, as is the third. > The forth is alpha, and I don't know the case. > The fifth is either 'q' or 'Q' > and soforth (either digit, some alpha, or a specific alpha of either case) With a recent Jumbo version, you can use --mask attack mode: ./john -1=[?u?l?d] --mask=[xX]?d?d?[a-zA-Z][qQ]?1?1?1?1?1 /path/to/passwdfile (I'm not sure for the non-Jumbo version, but it might work too). patpro
