The default port number for ssh is 22 is there a way to implement security by being obscure and changing the original number? So for example ssh would not be on port 22 it would be on lets say 2847.

1Just a note: do read the Wikipedia article that's the first result for "security by being obscure" in Google. – ceejayoz Feb 24 '14 at 21:57

@user180041 Uh... you don't use search engines? Fine, read this: http://en.wikipedia.org/wiki/Security_through_obscurity – ceejayoz Feb 24 '14 at 22:24

2@user180041, you don't need to be obtuse. 'Google it', are 'Google is your friend' are just a hint that have done a poor job at research, not a recommendation for a specific search engine. This doesn't mean you have to use Google, use your favorite search engine. – Zoredache Feb 24 '14 at 23:00

On most Linux system, the ssh port is defined in file :
/etc/ssh/sshd_config
With directive :
# What ports, IPs and protocols we listen for
Port 22
Change port for that directive, let's say :
# What ports, IPs and protocols we listen for
Port 2847
And restart sshd to apply changes :
service ssh restart
Now ssh should listen on port 2847
