monitoring SSH authorized_keys
Hi,

We have around 200 SUN Servers in production environment and I have one box from where I manage all the servers. It's setup such that I can SSH from my box onto all the 200 servers with without supplying password. It is working fine but sometimes we notice the keys getting changed and asking for password once in a while.

So, the requirement is to have a script that checks if I can login from my box to ALL 200 box without supplying password (i.e., ensuring no keys changed). The condition here we have is NOT to use RSH/RLOGIN for checking the keys or whatever it is for.

Any help highly appreciated

Thanks

       -f file
	      Write the secret key to the file file.

       -s bits
	      Set the key size to bits bits, should be multiple of 8 (optional).

       -y     Just print the publickey and fingerprint for the private key in file.

EXAMPLE

       generate a host-key:
	# dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key

       extract a public key suitable for authorized_keys from private key:
	# dropbearkey -y -f id_rsa | grep "^ssh-rsa " >> authorized_keys
