NAME
sss_ssh_knownhostsproxy - get OpenSSH host keys
SYNOPSIS
sss_ssh_knownhostsproxy [options] HOST [PROXY_COMMAND]
DESCRIPTION
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 establishes the 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
OPTIONS
-p,--port PORT
