This article describes how to perform remote connection using the ssh[1] tool.

1.1 Perform ssh connection[edit]

On host PC, one can type:

If it is a first connection:

 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):~# 

Otherwise:

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

If the below error message is showing, it means that sshd is not running on the target:

 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 ECDSA key...
