Note – if you are getting this error, you really should update the ios or your equipment. But there are situations where that cant be done – so –
Add the following lines to either the /etc/ssh/ssh_config file or the ~/.ssh/config file
replace x.x.x.x with the ip address or the FQDN of the host you are connecting to.
Note – if you dont include the line “
Ciphers +aes128-cbc” you will get the error message:
no matching cipher found. Their offer: aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc
