Password less SSH login to another server can be very useful when you want to configure a remote backup server or when migrating servers. For enabling this you need to have openSSH installed on the server. Here is a tutorial on how to configure password less SSH login to server ‘mars’ from server ‘earth’

1. Login to earth as root.

2. Run the command ssh-keygen -t rsa
If the key already exists you can either go to step 3 or you can generate a new key by overwriting existing key (see image). It would be better to overwrite the existing key if you did not generate it.




3. Change directory to /root/.ssh/

[email protected]:~# cd /root/.ssh/
[email protected]:~/.ssh#

4. Copy the contents of the file id_rsa.pub to the directory /root/.ssh/authorized_keys
scp -P id_rsa.pub [email protected]_server_IP:/root/.ssh/authorized_keys

5. You will be able to login to the remote server ‘mars’ by typing ssh [email protected]_server_IP -p without password nowRead more..

Is Linux secure? The question is much less useful, than 'Is Linux "securable"?' The answer to the latter is a definite yes.

Being securable means that Linux can be made more secure (to whatever degree necessary) by applying a clearly defined sequence

of steps that always produces the same result, and that can be automated and applied to systems that have been in operation for

a long time. It would be ideal to be able to make securing systems understandable by regular system administrators who don’t

have formal security training. However, the last requirement might be pushing it a bit, since security will likely always

require expertise.

Linux can be made more secure by hardening the system.

I wrote a step by step paper how to secure linux server with cP/WHM and
Apache installed. By default, linux is not secured enough but you have
to understand there is no such thing as "totally secured server/system".
The purpose of this paper is to understand how to at least provide some
kind of security to the server. I prefer lsws web-server without anyRead more..
