- Q: When i try to ssh into (router|switch) i get the message.
Unable to negotiate with x.x.x.x port 22: no matching key exchange found. Their offer diffie-hellman-group1-sha1
- A: edit /etc/ssh/ssh_config and uncomment
# MACs hmac-md5,hmac-sha1,hmac-sha2-256,email@example.com,hmac-ripemd160
# Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc
- and add these next few lines.
- Then you should be able to access the (switch|router) as you would over serial.
