openssh - how to confirm if it is running


Still googling/reading about openssh and decided to give it a try and wanted to be sure that my computer is safe while I am still reading/learning.


Installed openssh in Debian Testing -

- will ssh start upon boot up?
- how to disable ssh starting up upon boot up?
- how to confirm if ssh is already running?

Curious, is the rcconf similar (or the same) as sysv-rc-conf

rcconf is a user interface to update-rc.d. It just provides an ncurses based interface where you can add/remove startup scripts for services. Suitable in default debian/Ubuntu behaviour where the system starts in runlevel 2 with everything up and running.

sysv-rc-conf is more flexible that lets you configure and modify all runlevels by defining which services to start in what runlevel.

SSH on startup

If you are running a fedora Core system you
can su- to root then type:
system-config-services<enter>

or press the K button, press system, press services.
here you can turn ssh on or off at boot time. Remember
ssh uses ports 22 TCP, 22 UDP. Make sure these are open
on your firewall. ALSO make sure ssh is securely
configured SSH or the Secure shell is not secure at all
if you are careless about the configuration files. Make
sure you "bind" it to the proper Interfaces.

AFAIK ssh only uses port 22 TCP
However, you can tunnel UDP traffic true SSH

Ports

I stand partially corrected.
I looked in /etc/services. It listed Port 22
TCP, and UDP. In the spirit of precision I passed
this information along.

I use ssh on my RH9 RAID fileserver. In practice
I have never used port 22 UDP. This same server
uses Samba as well. I am occasionally guilty
of also using the GUI for file transfer between
the machines on my LAN.
