I was working on a ASR running code: asr1000rp1-ipbasek9.02.02.01.122-33.XNB1.bin. I wiped the config and started over from the last setup, and tried to SSH in. I was continually getting denied, and check the router – This error showed up.
1w2d: SSH2 0: RSA_sign: private key not found
1w2d: SSH2 0: signature creation failed, status -1
My first thought was to recreate the cert – so I did, still a no go.
I then recreated the cert with a different label or name, and then told the ASR to use this key pair instead – and everything worked. Its like I could not find the default key pair. The commands that I did to fix this are:
crypto key gen rsa general-keys label KEYPAIR-1 modulus 2048
ip ssh rsa keypair-name KEYPAIR-1
Then the ASR gave this back:
