SSSSSHHHHHHH Make silence

Today I spent too time! However, as the title, now we see SSH (Secure SHell), that is a network protocol that allow to establish encrypted remote connection by command line interface to another host of a computer network. It replaced the "insecure" telnet. It allows "secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers that connects, via a secure channel over an insecure network, a server and a client (running SSH server and SSH client programs, respectively)" - cit. Wiki.

So... in Kali, first, we need to type on shell the following command:

• sudo apt-get install ssh

After installation, we must check that SSH port is open (default port is 22). We check by command

• nmap localhost

This command shows us the ports that are open

If port 22 is close, you must consider some possibilities:

• You have to forward port by your router
• You have to run the server by command sudo /etc/init.d/ssh start
• Check sshd_config file by cat /etc/ssh/sshd_config

So, tomorrow I can try to bypass Steam blocks of university network :)
