When using ssh-v, the Unspecified GSS failure error occurs. This is mainly caused by the use of the GSSAPI authentication function. This is also the reason if you encounter a

[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 the logon speed is normal after logon. There are two possible reasons for this situation:1. DNS reverse resolution Problems OpenSSH will verify the IP address when you log on. It uses reverse DNS to locate the host name based on the user's IP address,

The solution to slow SSH Login is my own situation. Most of these latencies are caused by GSSAPI authentication! You can use the-v option to confirm your situation. For example, the detailed Logon Process of ssh is as follows: [root @ xuekun ~] # Ssh-v xuekun@192.168.15.120 ...... debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: includeded debug1: Authentications that can continue: publickey, gssapi-with-mic,
