In several howtos the steps to have a chrooted environment are explained very well. An essential item urgent to regard belongs to the debian based distributions, like ubuntu, where in the last weeks mass of upgrades to SSH are performed because of the well known bug with the ssh keys. Everybody running her/his server with chrooted environments should update after openssh upgrade with the one essential step: cd /tmp wget "http://chrootssh.sourceforge.net/download/openssh-4.5p1-chroot.tar.bz2" tar xvfj openssh-4.5p1-chroot.tar.bz2 cd openssh-4.5p1-chroot ./configure --exec-prefix=/usr --sysconfdir=/etc/ssh --with-pam make make install /etc/init.d/ssh restart In case of ignoring that adaption, each user entering the system via ssh is n o t chrooted. For hopefully the majority, this note is only a reminder. Hilmar
