Resolve the SSH connection server "ssh_exchange_identification: read: Connection reset by peer" problem

When we log in to the ECS server, we see that we cannot log in and a prompt "ssh_exchange_identification: read: Connection reset by peer" appears.

 ssh_exchange_identification: read: Connection reset by peer. sshd[11949]: refused connect from 192.168.0.0 (192.168.0.0).

There may be settings for security/ The/etc/hosts.allow or/etc/hosts.deny file enables TCP Wrapper access control.

1. Check the/etc/hosts.allow and/etc/hosts.deny files

 all:all:deny

2. Edit Logout

 # all: all:deny

Then we'll try again.

This should be based on operation and maintenance and security settings. In fact, it is not necessary. We can set the key to connect to SSH.
