Disabling SSH in eeebuntu

[jpareiasaur]

Ok. Absolute newbie. I'm trying to secure my computer from my brother, who is a hacking expert. A kind and wise group of Linux folks told me to disable SSH. I googled:
disable SSH Ubuntu
All the instructions tell me to edit the file:
etc/ssh/sshd_conf
However, this file does not seem to exist on my computer. (I guess this is because I'm using eeebuntu 3.0, not true Ubuntu.)
In /etc/ssh I have:
* moduli
* ssh_config

Should I edit one of those?

Or am I on the wrong track altogether? I am looking at the physical GUI files. Am I supposed to open a terminal and type one of those nifty sudo commands?

Sorry I'm so clueless! Thanks for any help you can provide.

Well, there are a couple of options. If you don't intend to use ssh at all, you could just uninstall the server.

sudo apt-get remove --purge ssh-server

Or you can turn off the ssh daemon through System->Administration->Services

Or you can block it from your /etc/hosts.deny file.

sudo gedit /etc/hosts.deny

and add the line sshd: ALL

You can also block all hosts from there with ALL:ALL in which case only hosts explicity allowed in /etc/hosts.allow could connect.
