Mikrotik RouterOS Scripting: Automating Networking Tasks

Managing network configurations can be a daunting task, especially in environments with complex requirements or frequent changes. Mikrotik RouterOS provides a powerful scripting feature that allows network administrators to automate routine tasks, saving time and minimizing human errors. In this guide, we’ll explore the basics of Mikrotik scripting and provide examples to help you get started.

1. What is Mikrotik RouterOS Scripting?

Mikrotik RouterOS scripting is a feature that enables users to create scripts to automate network management tasks. Scripts can be used to monitor the network, configure devices, perform backups, and more.

• Automate Routine Tasks: Simplify repetitive operations, such as updating configurations or generating reports.

• Enhance Efficiency: Execute tasks faster than manual configuration.

• Improve Consistency: Reduce the risk of errors associated with manual intervention.

2. Getting Started with Mikrotik Scripting

Before diving into scripting, ensure you have access to a Mikrotik router and are familiar with basic RouterOS commands. Here’s how to get started:

Step 1: Accessing the Terminal

Log in to your Mikrotik router via the Winbox tool or SSH, and open the terminal to input commands.

Step 2: Creating a Script

				
					# Example: Create a script to display system uptime
/system script add name="UptimeCheck" source=":put [ /system resource get uptime ]"
				
			

Step 3: Running a Script

				
					# Run the created script
/system script run UptimeCheck
				
			

The terminal will display the output of the script.

3. Common Use Cases for Mikrotik Scripts

1. Automated Backups

Create scripts to back up router configurations automatically

				
					# Backup script
/system script add name="AutoBackup" source="/system backup save name=backup-[/system clock get date]"
				
			

Schedule the script using the scheduler:

				
					/system scheduler add name="DailyBackup" on-event="AutoBackup" interval=1d
				
			

2. Dynamic Firewall Rules

Adjust firewall rules based on specific conditions:

				
					#Block IPs with more than 100 connections
/ip firewall address-list add list=block script=":foreach i in=[/ip firewall connection find where dst-limit>100] do={/ip firewall address-list add list=block address=[/ip firewall connection get $i src-address]}"
				
			

3. Bandwidth Monitoring

Monitor and log bandwidth usage:

				
					# Log interface bandwidth
/system script add name="LogBandwidth" source=":put [ /interface monitor-traffic ether1 once as-value ]"
				
			

4. Best Practices for Mikrotik Scripting

• Test Scripts: Always test scripts in a controlled environment before deploying them to production.

• Use Comments: Add comments to your scripts for better readability and documentation.

• Keep It Simple: Avoid overly complex scripts; break tasks into smaller, manageable scripts if necessary.

• Secure Your Scripts: Protect sensitive information, such as passwords, by using secure methods or environment variables.

5. Conclusion

Mikrotik RouterOS scripting is a powerful tool that can greatly enhance the efficiency and reliability of network management. By automating routine tasks, administrators can focus on more strategic activities, reducing manual errors and improving network performance. Start with simple scripts and gradually explore advanced functionalities to unlock the full potential of Mikrotik scripting.
