SSH Server Configuration

Secure Shell

Secure Shell or SSH is a network protocol that allows users to open a window on a local computer and connect to a remote computer as if they were sitting there. SSH allows data to be exchanged using a secure channel between two networked devices. Installing and configuring SSH is very easy in linux os. Here i am using Red Hat Enterprise Linux 6 Beta version Operating System to install the ssh server. This procedure is applicable tofedora and Red Hat Enterprise Linux 5 Operating Systems. The SSH is more secure when compare to Telnet.

Before installing the SSH Server, you must satisfy the minimum requirements

1. Your system must be configure with YUM. If not click here to configure.

2. IP Adress Configuration. ( My Server IP address is 192.10.10.2 )

Server Configuration

1. Open Terminal and login as root user.

2. Install SSH using YUM.

3. Refresh the services by restarting them.

# service network restart 

# service sshd restart

This command enables the service temporarily and to make it as permanent use chkconfig.

# chkconfig network on

# chkconfig sshd on

Client Configuration

The Client system should be configure with the network. Here my client ip address is 192.10.10.1 . Before conecting with the ssh server , check out the connectivity between the server and client. Use ping command to check the connectivity.

# ping 192.10.10.2

Now connect to the SSH Server

1. Open terminal in root user mode.

2. Use the ssh <ip address> . The Server prompt ask password of the user.

3. Exit is the command to logout from the server.
