[Switch] ssh logon is slow. Solution: ssh logon Solution
If you use an ssh client (such as putty) to connect to a Linux server, it may take 10-30 seconds to prompt you to enter the password. It seriously affects work efficiency. Logons are slow and
Symptom:
The serverA machine has produced the rsa key.
The public key has been added to the server B server/root/. ssh/authorized_keys
But the ssh root@135.251.208.141 machine still requires a password, that is, password-free authentication
