RouterOS Scripts

RouterOS is the operating system developed by MikroTik for networking tasks. This repository holds a number of scripts to manage RouterOS devices or extend their functionality.

Use at your own risk, pay attention to license and warranty!

Requirements

Latest version of the scripts require recent RouterOS to function properly. Make sure to install latest updates before you begin. If new functionality or a breaking change in RouterOS 7.n is used in my scripts I push my change some time after 7.(n+1) was released. At any time you should have at least two minor and their bugfix releases to choose from.

Specific scripts may require even newer RouterOS version.

ℹ️ Info: The main branch is now RouterOS v7 only. If you are still running RouterOS v6 switch to routeros-v6 branch!

Initial setup

Get me ready!

If you know how things work just copy and paste the initial commands. Remember to edit and rerun global-config-overlay! First time users should take the long way below.

Live presentation

Want to see it in action? I've had a presentation Repository based RouterOS script distribution including demonstation recorded live at MUM Europe 2019 in Vienna.

⚠️ Warning: Some details changed. So see the presentation, then follow the steps below for up-to-date commands.

The long way in detail

The update script does server certificate verification, so first step is to download the certificates. If you intend to download the scripts from a different location (for example from github.com) install the corresponding certificate chain.

/tool/fetch "https://git.eworm.de/cgit/routeros-scripts/plain/certs/E1.pem" dst-path="letsencrypt-E1.pem";

Note that the commands above do not verify server certificate, so if you want to be safe download with your workstations's browser and transfer the files to your MikroTik device.

ISRG Root X2
Let's Encrypt E1

Then we import the certificates.

/certificate/import file-name=letsencrypt-E1.pem passphrase="";

Do not worry that the command is not shown - that happens because it contains a sensitive property, the passphrase.

For basic verification we rename the certificates and print their count. Make sure the certificate count is two.

/certificate/set name="E1" [ find where common-name="E1" ];
/certificate/set name="ISRG-Root-X2" [ find where common-name="ISRG Root X2" ];
/certificate/print count-only where fingerprint="46494e30379059df18be52124305e606fc59070e5b21076ce113954b60517cda" or fingerprint="69729b8e15a86efc177a57afb7171dfc64add28c2fca8cf1507e34453ccb1470";

Always make sure there are no certificates installed you do not know or want!

All following commands will verify the server certificate. For validity the certificate's lifetime is checked with local time, so make sure the device's date and time is set correctly!

Now let's download the main scripts and add them in configuration on the fly.

:foreach Script in={ "global-config"; "global-config-overlay"; "global-functions" } do={ /system/script/add name=$Script source=([ /tool/fetch check-certificate=yes-without-crl ("https://git.eworm.de/cgit/routeros-scripts/plain/" . $Script . ".rsc") output=user as-value]->"data"); };

And finally load configuration and functions and add the scheduler.

/system/script { run global-config; run global-functions; };
/system/scheduler/add name="global-scripts" start-time=startup on-event="/system/script { run global-config; run global-functions; }";

Scheduled automatic updates

The last step is optional: Add this scheduler only if you want the scripts to be updated automatically!

/system/scheduler/add name="ScriptInstallUpdate" start-time=startup interval=1d on-event=":global ScriptInstallUpdate; \$ScriptInstallUpdate;";

Editing configuration

The configuration needs to be tweaked for your needs. Edit global-config-overlay, copy relevant configuration from global-config (the one without -overlay). Save changes and exit with Ctrl-o.

/system/script/edit global-config-overlay source;

To apply your changes run global-config, which will automatically load the overlay as well:

/system/script/run global-config;

This last step is required when ever you make changes to your configuration.

ℹ️ Info: It is recommended to edit the configuration using the command line interface. If using Winbox on Windows OS, the line endings may be missing. To fix this run: /system/script/set source=[ $Unix2Dos [ get global-config-overlay source ] ] global-config-overlay;

Updating scripts

To update existing scripts just run function $ScriptInstallUpdate. If everything is up-to-date it will not produce any output.

$ScriptInstallUpdate;

If the update includes news or requires configuration changes a notification is sent - in addition to terminal output and log messages.

Adding a script

To add a script from the repository run function $ScriptInstallUpdate with a comma separated list of script names.

$ScriptInstallUpdate check-certificates,check-routeros-update;

Scheduler and events

Most scripts are designed to run regularly from scheduler. We just added check-routeros-update, so let's run it every hour to make sure not to miss an update.

/system/scheduler/add name="check-routeros-update" interval=1h on-event="/system/script/run check-routeros-update;";

Some events can run a script. If you want your DHCP hostnames to be available in DNS use dhcp-to-dns with the events from dhcp server. For a regular cleanup add a scheduler entry.

$ScriptInstallUpdate dhcp-to-dns,lease-script;
/ip/dhcp-server/set lease-script=lease-script [ find ];
/system/scheduler/add name="dhcp-to-dns" interval=5m on-event="/system/script/run dhcp-to-dns;";

There's much more to explore... Have fun!

Available scripts

Available modules

Installing custom scripts & modules

My scripts cover a lot of use cases, but you may have your own ones. You can still use my scripts to manage and deploy yours, by specifying base-url (and url-suffix) for each script.

This will fetch and install a script hello-world.rsc from the given url:

$ScriptInstallUpdate hello-world "base-url=https://git.eworm.de/cgit/routeros-scripts-custom/plain/";

For a script to be considered valid it has to begin with a magic token. Have a look at any script and copy the first line without modification.

Starting a script's name with mod/ makes it a module and it is run automatically by global-functions.

Hello World (This is a demo script to show how the linking to external documentation will be done.)

ℹ️ Info: You have your own set of scripts and/or modules and want these to be listed here? There should be a general info page that links here, and documentation for each script. You can start by cloning my Custom RouterOS-Scripts (or fork on GitHub or GitLab) and make your changes. Then please get in contact...

Removing a script

There is no specific function for script removal. Just remove it from configuration...

/system/script/remove to-be-removed;

Possibly a scheduler and other configuration has to be removed as well.

Contact

We have a Telegram Group RouterOS-Scripts!

Get help, give feedback or just chat - but do not expect free professional support!
