router(config-line)#transport input ssh
It will require you to SSH to the router rather than telnet. You will have to use a program like Putty or some other SSH client.
The correct answer is:C"The switch Default tp allowing telnet connections only"SOme one gave me the wrong answer but this is the correct one
SSH.
ssh command provide secure access to a remote machine using terminal.Use the following syntax when using ssh to connect to a remote computerssh remote_username@remote_host
I assume you mean the user's ssh directory, which is stored in their home directory. Use the following command: rm -rf .ssh This will remove any previously used and verified ssh connections so any connections after that via ssh will need to be verified.
If an individual has the same username on the systems being check up on, they could use the command "$ ssh host who" at the prompt for who. This would bring up the listings for all the people who have logged on or off within a certain period of time on this particular system.
ssh or telnet in company environment mostly we used ssh and there is one tool called putty, through putty we can connect.
Under Windows the command is mstsc.Microsoft terminal server connection
To set up SSH with DSA/RSA public key authentication, you need to generate a key pair on the client machine using a command like ssh-keygen. Then, copy the public key to the server's ~/.ssh/authorized_keys file. Finally, make sure the permissions on the ~/.ssh/ directory and the authorized_keys file are secure (e.g., chmod 700 ~/.ssh and chmod 600 ~/.ssh/authorized_keys).
ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key for the DSA and RSA host keys, respectively (it will also create a corresponding .pub file). You can of course specify another filename and then move/copy them in place.
There is no command specific to SSH. Whether you are physically using the machine in question or using an SSH client the process is the same. On Ubuntu, one is encouraged not to use the root account directly. To execute a command as root, enter sudo . On distros that don't include sudo, you can gain a root shell by entering the command su root. Both commands will require you to enter either your admin password or the root password, respectively.
