Disable ssh boot on a home desktop

ahartman · 08-13-2009, 01:39 PM

Hi All

I have a xubuntu 9.04 home desktop system and
I won't be using ssh in the forseeable future.

What is the proper way to disable ssh on boot.
ssh-agent ?

TIA

I think there is a small program to do it for you but I just remove the links from the RC:

Code:

$ ls -l /etc/rc?.*|grep ssh
lrwxrwxrwx 1 root root  13 2009-02-20 14:08 K84ssh -> ../init.d/ssh
lrwxrwxrwx 1 root root  13 2009-02-20 14:08 S16ssh -> ../init.d/ssh
lrwxrwxrwx 1 root root  13 2009-02-20 14:08 S16ssh -> ../init.d/ssh
lrwxrwxrwx 1 root root  13 2009-02-20 14:08 S16ssh -> ../init.d/ssh
lrwxrwxrwx 1 root root  13 2009-02-20 14:08 S16ssh -> ../init.d/ssh

You can use
rcconf

Code:

sudo apt-get install rcconf

then in a terminal as root

Code:

sudo rcconf

I don't know what rcconf does but anything that works by removing symlinks int /etc/rc[S0-6].d is prone to being undone on upgrade. Inspection of /etc/init.d/ssh shows that it does not start if file /etc/ssh/sshd_not_to_be_run exists; that is how the writers of the script intended it to be disabled.

what if we change sshd_config ?e.g. "PasswordAuthentication no" and so on?

If you don't need or want ssh you can just uninstall it. Then it won't run.

Since Ubuntu supports chkconfig, "sudo chkconfig sshd off".
That will remove the symlinks in the /etc/init.d/rc.# run level directories.

You may have a graphical service configuration tool in your menu already.

You could also simply remove the executable bit from /etc/init.d/ssh
