How to perform ssh connection

Purpose

本文介绍如何使用ssh工具执行远程连接。

Perform ssh connection

在主机PC上，用户可以输入：

如果是第一次连接：

 PC $> ssh root@10.48.1.172
 The authenticity of host '10.48.1.172 (10.48.1.172)' can't be established.
 ECDSA key fingerprint is a0:a2:a3:09:b4:99:b3:90:6a:d0:35:05:6e:37:d0:6e.
 Are you sure you want to continue connecting (yes/no)? yes
 Warning: Permanently added '10.48.1.172' (ECDSA) to the list of known hosts.
 root@(none):~# 

除此以外：

 PC $>ssh root@10.48.1.172
 root@(none):~# 

如果显示以下错误消息，则表明sshd不在目标上运行：

 PC $>ssh root@10.48.1.172
 ssh: connect to host 10.48.1.172 port 22: Connection refused

On stm32mp1, one can type:

 Board $>mkdir /var/run/sshd
 Board $>/etc/init.d/sshd restart

In the console, the following log should appear:

 Board $>mkdir /var/run/sshd
 Board $>/etc/init.d/sshd restart
   generating ssh RSA key...
   generating ssh ECDSA key...
   generating ssh DSA key...

 Restarting OpenBSD Secure Shell server: sshdno /usr/sbin/sshd found; none killed
