How do I disable SSH from starting automatically?

Question

After installing openssh-server, the server start every time I boot. If I want it to be manual what do I need to do?

In version 0.6.7+ of upstart I would add a "manual" stanza to the job file.

10.04 has upstart 0.6.5-8. What is the preferred way to disable ssh from starting automatically in this case?

Answer 1

In your /etc/init/ssh.conf, comment out the start on line:

# ssh - OpenBSD Secure Shell server
#
# The OpenSSH server provides secure shell access to the system.

description     "OpenSSH server"

#start on filesystem or runlevel [2345]
stop on runlevel [!2345]

respawn
respawn limit 10 5
umask 022

Answer 2

This should be enough,:

 update-rc.d ssh enable # sets the default runlevels to on 
 update-rc.d ssh disable # sets all to off

Answer 3

Rename /etc/init/ssh.conf to /etc/init/ssh.conf.disabled.

sudo mv /etc/init/ssh.conf /etc/init/ssh.conf.disabled

Answer 4

sudo apt-get install bum

Start bum with administrative privileges, disable openssh-server, confirm it, done.

Answer 5

For versions with ssh started by upstart, run touch /etc/ssh/sshd_not_to_be_run. The upstart init script checks for this file and, if existent, does not start sshd.
