Under Solaris, if you let ssh connect to the root user

Svcadm enbale-rt SSH
By default, OpenSSH prevents the root account from being logged in via SSH to ensure security. In order to be lazy, the Server's environment is not dangerous, so you want to be able to telnet to the Solaris server on their own machines.

The method is as follows:

Modify the/etc/ssh/sshd_config file, modify the "Permitrootlogin No" to "Permitrootlogin yes", and then perform the svcadm restart SSH reboot ssh service. Last step: Allow the server to automatically enable the SSH service each time it restarts by creating a file such as "Sxxxservicename" under the/etc/rc2.d/folder-note that the first letter must be capitalized, XXX is a number, and the order of startup is and write the following command in the file: "Svcadm enable-rt ssh" Save, reboot
