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-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
