Cisco Router Generate Rsa Key
Run show crypto key mypubkey rsa to see if you do, in fact, have a key fully generated and registered under a non-default name. If there is, then you can tell the ssh process to use this key with ip ssh rsa keypair-name xxx. If the first command doesn't show anything useful then I'd say you can go ahead and generate a new key. How I create RSA key and enable SSH access in Cisco VG202, in a Cisco router I use the next commands(but in a VG not exists): conf t. Crypto key generate rsa modulus 1024 ip domain-name domain-name ip ssh version 2 ip ssh time-out 120 ip ssh authentication-retries 3 line vty 0 4 transport input telnet ssh end.
Main Command: ip ssh pubkey-chain[1]
Configuration Example in Linux:
1. Generate your key if you do not have already one: ssh-keygen
2. Split your key in 72 characters lines: fold -b -w 72 ~/.ssh/id_rsa.pub and copy output removing ssh-rsa and last part: username@hostname
3. Configure switch/router
View config:
Posible errors:%SSH: Failed to decode the Key Value. Make sure you split your key on multiple lines with fold command
