I am running the latest build of OpenSSH (4.3p2) from CentOS 5. When I attempt to start the server with
/etc/init.d/sshd start, this is the output from bash:
Starting sshd: /etc/ssh/sshd_config: line 130: Bad configuration option: HashKnownHosts /etc/ssh/sshd_config: line 134: Bad configuration option: StrictHostKeyChecking /etc/ssh/sshd_config: terminating, 2 bad configuration options
My man page for sshd indicates that it supports a hashed known_hosts file, but the man page I have for sshd_config does not mention either of these directives.
Are HashKnownHosts and StrictHostKeyChecking included in the RHEL / CentOS maintained version of OpenSSH?
If not, what work-arounds are available to me? Can I safely install the newest stable version of OpenSSH from source? I'm unwilling to leave known_hosts in plain-text.
