Please
create RSA keys (of at least 768 bits size) to enable SSH v2.

alexrouter(config)#crypto
key generate rsa
The name for the keys will be: alexrouter.cbtme.com
Choose
the size of the key modulus in the range of 360 to 2048 for your
General
Purpose Keys. Choosing a key modulus greater than 512 may take
a few
minutes.

How many bits in the modulus [512]: 512
% Generating
512 bit RSA keys, keys will be non-exportable...[OK]

*Mar 1
