Resolve issues where you cannot log in to BT5 through SSH
1. Check whether ssh. 1 is installed on BT5.
2. Check whether the service is enabled, ps-e | grep ssh
3. Check whether the ssh is configured correctly, vi / etc/ssh-config, where port and protocol are annotated by default, so the comments should be removed.
4. Ssh is authenticated through the local key, so make sure that the key exists locally. If not, you can use the command to generate: ssh-generate.
