sss_ssh_knownhostsproxy 1
sss_ssh_knownhostsproxy get OpenSSH host keys
`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 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

### OPTIONS

`-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.

### EXIT STATUS

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