How to make server via SSH remote command execution?

0x00 Foreword

I have a Pi, hanging from a service, but this service as long as there is no communication for a long time will have their own hang. Try to use crontab automatically restart every hour, sometimes still have to manually restart the service.

So, I would like simply to use every time you open a terminal when it got started.

But each time SSH, lost password, execute the command too much trouble, you can not just think of this done with a single command.

0x01 SSH command execution

Looked under the manual, execute commands by SSH, in fact, just add commands after the hostname would be finished.

ssh [email protected] reboot

0x02 free dense Login

Remote execution of commands ok, it would have to solve some secret free to sign up.

The SSH also has built-in tools can be resolved.

First by the host ssh-keygengenerates a public-private key pair

ssh-keygen

All the way round, then default on the public key stored in ~/.ssh/id_rsa.pubthe.

Then copying the public key of the server's ~/.ssh/authorized_keysfile

ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]

Then the server can be free-tight connection, remote execution of commands for Free adhesion.

But every time you turn a long list of commands or trouble, there is no way to complete a word of it?

0x03 command aliases

I do not know aliashow to translate, but the meaning is probably an alias.

Editing ~/.bashrc, this file is automatically executed every time you open a terminal time.

In the end, add a

alias lalala="ssh [email protected] reboot"

Then just hit the terminal lalala, the server restart.

Here is rebootreplaced by the command you want to execute it.
