The error is as follows:

Ssh_exchange_identification: read: Connection reset by peer

Lost connection

Cause of the problem

This problem is usually caused by enabling TCP Wrapper access control on the Linux system through / etc/hosts.allow or / etc/hosts.deny.

Treatment method

To resolve this issue, make the following configuration checks and modifications:

Enter the system through the management terminal.

Use instructions such as cat to see if / etc/hosts.allow or / etc/hosts.deny contains configurations similar to the following:

All:all:deny

If you need to modify the relevant policy configuration, it is recommended that you back up the files before continuing.

Using editors such as vi, modify the relevant configuration in / etc/hosts.allow and / etc/hosts.deny as needed, or delete or comment the entire line configuration (with a # sign at the beginning). For example:

All:all:deny

Vi / etc/hosts.allow

For all other comments, add:

Sshd: ALL

Restart ssh and you will ok.

Service sshd restart (centos6)

Systemctl restart sshd (centos7)
