ssh-agent is usually started in the beginning of an X-session or a login session, and all other windows or programs are started as clients to the ssh-agent program. Through use of environment variables the agent can be located and automatically used for authentication when logging in to other machines using ssh

SSH(7) Erlang Application Definition SSH(7) NAME SSH – The ssh application implements the Secure Shell (SSH) protocol and provides an SSH File Transfer Protocol (SFTP) client and server. DESCRIPTION The ssh application is an implementation of the SSH protocol in Erlang. ssh offers API functions to write customized SSH clients and servers as well as making the Erlang shell available over SSH.
If this option is set to “no” (the default) then only addresses and not host names may be used in ~/.ssh/known_hosts from and sshd_config Match Host directives. UseLogin Specifies whether login(1) is used for interactive login
If this option is set to “yes” and a key is loaded from a file, the key and its passphrase are added to the agent with the default lifetime, as if by ssh-add1. If this option is set to “ask” ssh will require confirmation using the SSH_ASKPASS program before adding a key

ssh (SSH client) is a program for logging into a remote machine and for executing commands on a remote machine. It is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an insecure network.
An rsync server is configured using a config file which by default is called /etc/rsyncd.conf. Please see the rsyncd.conf(5) man page for more information. Examples To Backup the home directory using a cron job: rsync -Cavz . server64:backup Run the above

The first ssh_config path, above, provides the system-wide defaults for ssh(1). The second version is user-specific defaults for ssh . ssh obtains configuration data from the following sources, in this order: command line options, user’s configuration file (/etc/ssh).
The man page for sshd has a section on the authorized_keys format, where it states that the comment extends to the end of the line. While I haven’t tried it, you should be able to put spaces into the comment.

The Linux man-pages project The Linux man-pages project documents the Linux kernel and C library interfaces that are employed by user-space programs. With respect to the C library, the primary focus is the GNU C library (), although, where known, documentation of variations on other C libraries available for Linux is also included.
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be

ssh-keyscan uses non-blocking socket I/O to contact as many hosts as possible in parallel, so it is very efficient. The keys from a domain of 1,000 hosts can be collected in tens of seconds, even when some of those hosts are down or do not run ssh. For scanning

If an ssh_known_hosts file is constructed using ssh-keyscan without verifying the keys, users will be vulnerable to man in the middle attacks. On the other hand, if the security model allows such a risk, ssh-keyscan can help in the detection of tampered keyfiles or man in the middle attacks which have begun after the ssh_known_hosts file was created.
The file above can be used for any client side SSH configuration. See the ssh_config man page for more details. The ‘TCPKeepAlive yes’ directive tells the ssh client that it should send a little bit of data over the connection periodically to let the server know that it
