Hi Darren,

Sorry to disturb you again. Hope you are doing good. Facing some other
issue at run time.

Server was in 8.0p1 version and generated ssh-rsa & ssh-dsa key pairs.
Able to login from client. Later Server downgraded to 5.3p1, after
reboot it generates only ssh-rsa1(i guess its ssh protocol 1) key
pairs. And client not able to connect to sshd as sshd crashed. Please
find the below logs.

debug3: checking syntax for 'Match (null)'
debug1: sshd version OpenSSH_5.3p1
debug3: Not a RSA1 key file /etc/ssh/ssh_host_rsa_key.
debug1: PEM_read_PrivateKey failed
debug1: read PEM private key done: type <unknown>
Could not load host key: /etc/ssh/ssh_host_rsa_key
debug3: Not a RSA1 key file /etc/ssh/ssh_host_dsa_key.
debug1: PEM_read_PrivateKey failed
debug1: read PEM private key done: type <unknown>
Could not load host key: /etc/ssh/ssh_host_dsa_key
Disabling protocol version 2. Could not load host key
sshd: no hostkeys available -- exiting.

I guess ssh-protocol 1 also we need to enable. Is it? If yes, how to do
it?

Thanks in advance.
