The well-known traditional port for ssh is port 22.
SSH Stands for Secure Shell and always run port number 22
rsh and ssh are similar in that they can execute commands on remote systems. The main difference between the two (besides the actual TCP ports) is that rsh traffic is not encrypted and therefore a security risk; ssh traffic is encrypted. The other main difference is that ssh is a secure replacement for telnet, whereas rsh can log into a remote system using the rlogin protocol, which is similar but not the same as telnet.
Typically it would be a hidden folder called ".ssh".
SSH is extremely simple. Using the SSH client, you connect to the computer running the SSH server using the commandssh [ip address or hostname here]
An SSH Keygen is used to generate, manage, and convert authentication keys for SSH authentication. With an SSH Keygen tool, a user can create passphrase keys for both SSH protocol version 1 and 2.
/etc/ssh/sshd_config In some distributions it can be in odd places like /etc/sshd_config, /usr/local/etc/ssh/sshd_config
ssh
Most Linux distributions will come with SSH preinstalled. If it's not, install the package "ssh".
It is usually referred to simply as "SSH."
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).
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.
sshd is the package provide ssh sessions .
