Crypto key restores

Phil Green

I have a new Cisco 2911 router that I have reset to factory defaults a couple of times.  I somehow lost the cypto keys in all of the resets and would like to regenerate or get new ones.  How do I go about doing that?

I actually found the last good configuration and copied it to running-config.  Now, though, I can telnet from remote but not SSH.

 

Here's the config

ip http access-class 23
access-list 23 permit xx.xx.xx.xx 0.0.0.255

 

line vty 0 4
 access-class 23 in
 privilege level 15
 password xxxxxxx
 login local
 transport input ssh

line vty 5 15
 access-class 23 in
 privilege level 15
 login local
 transport input telnet ssh

 

Like I said, telnet works but not ssh.  Telnet shouldn't work.  Right?

 

Lines 5-15 permit telnet so that's why that is working.

For ssh, do you have an rsa crypto key created?
