I've got a debian package with the chroot patch enabled, and search this mailing list, there was some discussions about that last year. You can get my package for woody here: http://debian.home-dn.net/woody/ ssh/ Debian people question: What about making a ssh-chroot package, made of the current ssh package and just the chroot patch enabled? It will be easier to maintains systems with the need of chroot and, as it will be more used, there will be more people to really audit it! -- Easter-eggs Spécialiste GNU/Linux 44-46 rue de l'Ouest - 75014 Paris - France - Métro Gaité Phone: +33 (0) 1 43 35 00 37 - Fax: +33 (0) 1 41 35 00 76 mailto:[EMAIL PROTECTED] - http://www.easter-eggs.com
