SSH 登录思科路由器RSA modulus too small处理
问题现象：ssh_rsa_verify: RSA modulus too small: 512 < minimum 768 bits
key_verify failed for server_host_key
临时解决：
用ssh -v -1 -c des参数连接
test@linux:~$ ssh -v -1 -c des root@10.1.1.1
永久解决方法：
liyi-cisco7200(config)#crypto key zeroize rsa
% All RSA keys will be removed.
% All router certs issued using these keys will also be removed.
Do you really want to remove these keys? [yes/no]: yes
cisco7200(config)#crypto key generate rsa general-keys
The name for the keys will be: liyi-cisco7200.liyi.liyi.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]: 1024
% Generating 1024 bit RSA keys ...[OK]
