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

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

Aric Campling, MozillaQuest: [The book] can provide you with a wealth of knowledge to make any Debian task easier, more efficient, and relatively painless. [...] Krafft details a set of additional Debian software management tools that aid the user or administrator in maintaining a clean, streamlined system.
