SSH telnet to the Linux live system

To SSH telnet, you need to prepare two things: Configure the same network segment IP and open the SSH service.

Because the live system does not have an IP, you first need to configure the IP.

My live system is started on the virtual machine, the IP of the host IP for the 192.168.230.1,live system is set to 192.168.230.180:

#ifconfig eth0 192.168.230.180

Then connect the live system on the SECURITYCRT and enter the password to find that the live system does not have a user password. If you do not lose the password or enter a password, SECURITYCRT is not allowed to connect. So you need to configure the password on the live system, the live system is the root user login by default. Use the passwd command to modify the password.

Next enter the password connection will output the following failure message, because the live system SSH service does not open:

The remote system refused the connection.

Next turn on the SSH service for the live system:

#/etc/rc.d/init.d/sshd start

Then use the SECURITYCRT connection to succeed:

Last Login:sat 13:14:34 2014lfslivecd:root | Sat 31 13:24:42 2014 | ~#

To summarize, there are three steps in total:

1. Configure IP

2. Set Root password

3. Open SSH Service

Note:

If you start the SSH service and then set the root password, you will need to restart the SSH service after setting the root password.
