sss_ssh_knownhostsproxy1

Usage

Overview

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

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.

-k,--pubkey

Print the host ssh public keys for host HOST.

-?,--help

Display help message and exit.

Exit status

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