It was initially designed and developed in an operating system (Linux) that has fantastic and multiple facilities for putting any kind of job into background processing (screen being my favorite of the bunch). All that to say: John has never needed any direct support for such facilities, and although forking into the background would be trivial and mildly useful, the code to re-join or alert would be rather non-trivial and everyone would want something different. I, for one, would rather have Solar et. al. focus their [unpaid] coding skills on speed improvements and eventual SMP - it would be trivial for most users to write a wrapper script around John and make it fork/alert/whatever consistently. That brings up SMP - I agree with you and the dozens who have said it would be a fantastic addition, but given the nature of the specific problem John addresses, parallel processing becomes very ugly and not easily addressed. I have had some decent luck with the MPLS version of John when I just *had* to go brute-force, but it is neither fantastically quick or optimal. One of these days when we least expect it, Solar will unleash his mad coding f00 on the world with a properly-done SMP implementation, and the world of non-blowfish passwords will quake in their boots. :-D -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
