Thank you!
From the information you have provided, I can infer that there could be a
problem with your RSA keys ("accumulate_host_timing_secret: encode ssh-rsa key:
string is too large").
Would you mind:
1. Back-up the current RSA keys:
# cp -p /etc/ssh/ssh_host_rsa_key /etc/ssh/ssh_host_rsa_key.bak
# cp -p /etc/ssh/ssh_host_rsa_key.pub /etc/ssh/ssh_host_rsa_key.pub.bak
2. Attempt to start the service (it will generate a new pair of RSA keys for
you):
# service sshd start
If this works, please do not discard the backed-up keys. I would be interested
to see what actually happened.
If the problem persists, please verify that the /etc/ssh/moduli file is valid.
Or if you have additional configuration options:
sysrc -a | grep sshd
Or non-default settings in /etc/ssh/sshd_config.
