This article is like one of the sekure.org "teaching" how to "break" ssh after you got root on a given machine using ktrace. Not he's wrong but even Mitnick had beter ideas on VMS macines about trojaning PGP 5 years ago. Anyway while the article is very-very good it seems the markting was more slashdot oriented than security itself, I can see that "unknow user" at kernel@tdnet.com.br removing freebsd from his servers due freebsd being unsecure. I think articles like this one should be part of FBSD documentation not only as a digest but also with an url to the original paper, we had other good papers on *BSD internals in phrack and other uground publications that never got to www.freebsd.org > N > -- > [intentional self-reference] can be easily accommodated using a blessed, > non-self-referential dummy head-node whose own object destructor severs > the links. > -- Tom Christiansen in <375143b5@cs.colorado.edu> > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-current" in the body of the message > -- Whenever you find that you are on the side of the majority, it is time to reform. -- Mark Twain To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
