Automatically enabling SSH server on a router. AM 12-13-2005

In order to automate the configuration of a router I insert the following command
"crypto key generate rsa general-keys modulus 1024"
but on startup the router says
"Rsa keys can't be generated by the startup configuration"

That's true otherwise keys will change every reload. But how to have dozens of
routers set up and ready to be installed
and contacted by remote without doing a 2 step configuration? I mean once
started up I can contact the router via expect
through a telnet connection on my LAN (for example) and then tell the router to
create RSA keys.

See if this will work:

! Generate RSA key

kron policy-list GEN_RSA
cli crypto key generate rsa general-keys modulus 1024
exit

kron occurrence in 5 oneshot
policy-list GEN_RSA
exit

No it doesn't. Doing a "sh run" the router has removed the kron command that
would have started the kron policy.
