Hi,Im currently deploying signed host keys for my environment. Everything seems to work fine but I have one problem with host based authentication.
Im running OpenSSH_6.5p1, OpenSSL 1.0.1e-fips 11 Feb 2013 on RHEL 6.5.When trying to login between hosts with host-based authentication configured I cant do so if the host is not in /etc/ssh_knows_hosts. If its there it works even if the public key is wrong. It should be enough to have a single "@cert-authority" line in ssh_known_hosts right?
m1# ssh m3 -v ... debug1: Host 'm3' is known and matches the RSA-CERT host certificate. debug1: Found CA key in /etc/ssh/ssh_known_hosts:1 ... debug1: ssh_rsa_verify: signature correct ----- m3# /usr/sbin/sshd -dd ...debug3: load_hostkeys: loading entries for host "m1" from file "/etc/ssh/ssh_known_hosts" debug3: load_hostkeys: found ca key type RSA in file /etc/ssh/ssh_known_hosts:1
debug3: load_hostkeys: loaded 1 keys debug1: check_key_in_hostfiles: key for host m1 not found debug1: check_key_in_hostfiles: key for host m1 not found Why cant I use the CA for host based auth?
