An SSH server is a daemon that listens for requests to log in using SSH from remote computers. SSH basically allows you to control a Linux or Unix computer just as if you were sitting at the physical machine.
Short for Open Secure Shell, OpenSSH is a free suite of tools (similar to the SSH connectivity tools) that help secure your network connections. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking and other network-level attacks.
The OpenSSH suite includes the ssh program that replaces rlogin and telnet, and scp which replaces rcp and ftp. OpenSSH has also added sftp and sftp-server which implement an easier solution for file-transfer. OpenSSH comes in two downloadable distributions: the native OpenBSD distribution and the multi-platform portable distribution. OpenSSH is developed by the OpenBSD Project.
SSH (Secure Shell) is a client/server package used in Unix and Linux systems to provide secure access to a remote system.
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.
The well-known traditional port for ssh is port 22.
sshd is the package provide ssh sessions .
There is no particular program meant to replace SSH. SSH is considered a modern and secure program, so there is no reason to replace it.
