SSH encrypts all data sent between machines, ensuring that no sensitive data is leaked. SSH protocol is the best way for Ubuntu users to remotely access and manage servers. Enter your password when prompted and you will find yourself logged into the remote system.Connection security is the most important criteria when setting up a remote connection between a client and a server. To connect from a remote system perform the same steps above using either the IP address or host name of the remote host to which you connect. Similarly, the hostname may be obtained by running the hostname tool at a terminal command prompt. In the above output the IP address is shown as inet addr:, in this case 192.168.2.21. TX packets:4409081 errors:0 dropped:0 overruns:0 carrier:0 RX packets:4261067 errors:0 dropped:0 overruns:0 frame:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 This will output information similar to: eth0 Link encap:Ethernet HWaddr 00:13:72:0B:14:57 If you do not know the IP address run the ipconfig command in a terminal window. You can also substitute the hostname of the system in place of the IP address. Where username is the name of the user you wish to log in as and ipaddress is the IP address of your system. To connect from your local machine back to itself use the following command: ssh -l username ipaddresss SSH connections are established using the ssh client utility. It is also possible to test that the SSH server is running and accessible from the local machine. SSH can be used to log into your system from a remote system. If you receive a "connection refused" message when you try to connect you may need to configure the firewall to allow SSH connections to be established to this system.
