Ssh(1)— The basic rlogin/rsh-like client program sshd(8)— The daemon that permits you to log in. This tutorial focuses on setting up and configuring a SSH server on a Debian 10 minimal server. SSH, for Secure Shell, is a network protocol that is used in order to operate remote logins to distant machines within a local network or over Internet.SSH architectures typically includes a SSH server that is used by SSH clients to connect to the remote machine.

Overview

RouterOS provides SSH client that supports SSHv2 logins to SSH servers reachable from the router.

Requirements

For this command to be available router has to have system and security packages installed.

SSH

Sub-menu:/system ssh

Simple log-in to remote host

It is able to connect to remote host and initiate ssh session. IP address supports both IPv4 and IPv6.

In this case user name provided to remote host is one that has logged into the router. If other value is required, then user=<username> has to be used.

Log-in from certain IP address of the router

Ssh Manual Pdf

For testing or security reasons it may be required to log-in to other host using certain source address of the connection. In this case src-address=<ip address> argument has to be used. Note that IP address in this case supports both, IPv4 and IPv6.

in this case, ssh client will try to bind to address specified and then initiate ssh connection to remote host.

Log-in using public/private key

For this to work user has to set up a public key on the remote end where ssh will connect to. How to do that on RouterOS you can read here. On local end router, public and private keys have to be uploaded to be used in /user ssh-keys private when adding private key and a user name that will be able to use this key.

Example of importing private key for user lala

Warning: Only user with full rights on the router can change 'user' attribute value under /user ssh-keys private

Ssh Manual Port

Executing remote commands

To execute remote command it has to be supplied at the end of log-in line

Warning: If the server does not support pseudo-tty (ssh -T or ssh host command), like mikrotik ssh server, then it is not possible to send multiline commands via SSH

For example, sending command '/ip address n add address=1.1.1.1/24' to MikroTik router will fail.

Note: If you wish to execute remote commands via scripts or scheduler, use command ssh-exec.

SSH-exec

Sub-menu:/system ssh-exec

Command ssh-exec is a non-interactive ssh command, thus allowing to execute commands remotely on a device via scripts and scheduler.

Retrieve information

The command will return two values:

• ) exit-code: returns 0 if the command execution succeeded
• ) output: returns the output of remotely executed command

Example:Code below will retrieve interface status of ether1 from device 10.10.10.1 and output the result to 'Log'

Note: For security reasons, plain text password input is not allowed. To ensure safe execution of the command remotely, use SSH key authentication for users on both sides.
An example of how to configure RSA key pair authentication can be found in: https://wiki.mikrotik.com/wiki/Use_SSH_to_execute_commands_(public/private_key_login)

Warning: the user group and script policy executing the command requires test permission
