sss_ssh_knownhostsproxy — get OpenSSH host keys


sss_ssh_knownhostsproxy [ options ] HOST [PROXY_COMMAND]


sss_ssh_knownhostsproxy acquires SSH host public keys for host HOST, stores them in a custom OpenSSH known_hosts file (see the SSH_KNOWN_HOSTS FILE FORMAT section of sshd(8) for more information) /var/lib/sss/pubconf/known_hosts and estabilishes connection to the host.

If PROXY_COMMAND is specified, it is used to create the connection to the host instead of opening a socket.

ssh(1) can be configured to use sss_ssh_knownhostsproxy for host key authentication by using the following directives for ssh(1) configuration:

ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p %h
GlobalKnownHostsFile /var/lib/sss/pubconf/known_hosts


-p,--port PORT

Use port PORT to connect to the host. By default, port 22 is used.

-d,--domain DOMAIN

Search for host public keys in SSSD domain DOMAIN.


Display help message and exit.


In case of success, an exit value of 0 is returned. Otherwise, 1 is returned.
