Faulty way of spawning sshd in single-user mode (page 299)

Reported on: 2006-10-22

In chapter 6. Debian system administration on page 299:

In chapter 6.3.1, I suggest to add sshd to the /etc/inittab file to be able to login to a remote system even in single-user mode:

# sed -i -e "/^~~/ish:S:respawn:sshd -Do 'AllowUsers=root'" /etc/inittab

Unfortunately, there are two errors with this: first, sshd must be called with the complete path (to guard against trojans), and init must be told to reload the configuration file after the change.

The following corrects both problems:

# sed -i -e "/^~~/ish:S:respawn:/usr/sbin/sshd -Do 'AllowUsers=root'" /etc/inittab
# telinit q
Feedback

Christian Einfeldt, MadPenguin: Charles Darwin would “get” the beauty Debian if he were alive today. Martin Krafft certainly “gets” the beauty of Debian, and he wants you to get it too, so he has written a very detailed exposition of the Debian code and community. [...] If there was one word that I would use to describe Martin's book, that word would be “meticulous.”
