Subject: Re: [LinuxUsers] SSH Public Key Authenticatio

That guide was written as a general guide to implementing it so you need to 
adapt to the environment you are running on.  For ubuntu it is

/etc/init.d/ssh reload

CentOS is the one in the guide

/etc/init.d/sshd reload


You don't need to run ssh-agent, that is so you don't get prompted for a 
password for the key.

Towards the end of the post: PasswordAuthentication no

That will prevent password based ssh logins, but if your friend ever wanted to 
login to the machine from another and did not have a key setup he would be up 
the brown creek without a paddle.  By disabling passwords you will take care of 
1 and 2 because if the person does not have the key and passwords are off they 
get denied.


If you look at my lockdown post you will see more stuff you can do for ssh 
security

Using Peter Manis' tutorial on Public Key authentication at URL:
http://pyverted.com/sysadmin/ssh-public-key-authentication/2008/10/

I was able to get SSH up and running with a public key authentication 
on my friend sam's computer. Everything worked great.
I did not execute the commands:
exec ssh-agent /bin/bash
ssh-add


until the next day, when I realized that I had not done
it the day before. The two computers were not connected
when I executed these commands. I am assuming that these 
commands can be executed on the local machine only, and 

the remote machine doesn't need to know about them.
am I correct.

also, when I did the command:
sudo /etc/init.d/sshd reload

bash reported: "command not found"

nevertheless, I want the 2 features that this command provides,

which are:

1. Removes the ability to login to the server with a password, you can only 
login to the server using a public key.

2. Limit the machine that you can login from. The remotemach must
have the key for the localmach in the authorized_keys file before
authentication can be performed.


Is there something I can to to configure these features, or is there a way to 
add
these commands to my bash commands?
Thanks
