Hi - SSH suddenly stopped working on our ASR 1001-x.
investigating showed the following:
sho ip ssh
SSH Enabled - version 1.99
Authentication methods:publickey,keyboard-interactive,password
Authentication Publickey Algorithms:x509v3-ssh-rsa,ssh-rsa
Hostkey Algorithms:x509v3-ssh-rsa,ssh-rsa
Encryption Algorithms:aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc
MAC Algorithms:hmac-sha1,hmac-sha1-96
Authentication timeout: 120 secs; Authentication retries: 3
Minimum expected Diffie Hellman key size : 1024 bits
IOS Keys in SECSH format(ssh-rsa, base64 encoded): VA.CPCH.HQ.ASR.esvc.us
%SSH: Failed to encode IOS ASN.1 to SECSH format
We tried to zero the existing key and regenerate a new key. no change. reboot the ASR, no change. Telnet works so we are not dead in the water, but we really want to restore SSH access for obvious reasons.
Any help appreciated
Thank you
Ronald
