RouterOS Scripts

GitHub forks GitHub stars GitHub watchers

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!


Latest version of the scripts require recent RouterOS to function properly. Make sure to install latest updates before you begin.

Specific scripts may require even newer RouterOS version.

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.

Be warned! 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.

[admin@MikroTik] > / tool fetch "https://git.eworm.de/cgit/routeros-scripts/plain/certs/Let%27s%20Encrypt%20Authority%20X3.pem" dst-path="letsencrypt.pem"
      status: finished
  downloaded: 3KiBC-z pause]
       total: 3KiB
    duration: 1s

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.

Then we import the certificates.

[admin@MikroTik] > / certificate import file-name=letsencrypt.pem passphrase=""
     certificates-imported: 3
     private-keys-imported: 0
            files-imported: 1
       decryption-failures: 0
  keys-with-no-certificate: 0

For basic verification we rename the certifiactes and print their count. Make sure the certificate count is three.

[admin@MikroTik] > / certificate set name="ISRG-Root-X1" [ find where fingerprint="96bcec06264976f37460779acf28c5a7cfe8a3c0aae11a8ffcee05c0bddf08c6" ]
[admin@MikroTik] > / certificate set name="Let-s-Encrypt-Authority-X3" [ find where fingerprint="731d3d9cfaa061487a1d71445a42f67df0afca2a6c2d2f98ff7b3ce112b1f568" ]
[admin@MikroTik] > / certificate set name="DST-Root-CA-X3" [ find where fingerprint="0687260331a72403d909f105e69bcf0d32e1bd2493ffc6d9206d11bcd6770739" ]
[admin@MikroTik] > / certificate print count-only where fingerprint="96bcec06264976f37460779acf28c5a7cfe8a3c0aae11a8ffcee05c0bddf08c6" or fingerprint="731d3d9cfaa061487a1d71445a42f67df0afca2a6c2d2f98ff7b3ce112b1f568" or fingerprint="0687260331a72403d909f105e69bcf0d32e1bd2493ffc6d9206d11bcd6770739"

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

Actually we do not require the certificate named DST Root CA X3, but as it is used by Let's Encrypt to cross-sign we install it anyway - this makes sure things do not go wrong if the intermediate certificate is replaced. The IdenTrust certificate should be available from their download page. The site is crap and a good example how to not do it.

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

[admin@MikroTik] > :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) output=user as-value]->"data"); }

Mark global-config-overlay not to be overwritten by future updates.

[admin@MikroTik] > / system script set comment="ignore" global-config-overlay

The configuration needs to be tweaked for your needs. Make sure not to send your mails to mail@example.com! Edit global-config-overlay, copy configuration from global-config (the one without -overlay).

[admin@MikroTik] > / system script edit global-config-overlay source

And finally load configuration and functions and add the scheduler.

[admin@MikroTik] > / system script { run global-config; run global-config-overlay; run global-functions; }
[admin@MikroTik] > / system scheduler add name="global-scripts" start-time=startup on-event="/ system script { run global-config; run global-config-overlay; run global-functions; }"

Updating scripts

To update existing scripts just run function $ScriptInstallUpdate.

[admin@MikroTik] > $ScriptInstallUpdate

Adding a script

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

[admin@MikroTik] > $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.

[admin@MikroTik] > / 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.

[admin@MikroTik] > $ScriptInstallUpdate dhcp-to-dns,lease-script
[admin@MikroTik] > / ip dhcp-server set lease-script=lease-script [ find ]
[admin@MikroTik] > / 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!
