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!

Requirements

Latest version of the scripts require at least RouterOS 6.43 to function properly. The changelog lists the corresponding change as follows:

*) fetch - added "as-value" output format;

See branch pre-6-43 if you want to use the scripts on devices with older RouterOS version.

Initial setup

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.cgi/routeros-scripts/plain/certs/731d3d9cfaa061487a1d71445a42f67df0afca2a6c2d2f98ff7b3ce112b1f568.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.

• ISRG Root X1
• Let's Encrypt Authority X3

Then we import the certificates.

[admin@MikroTik] > / certificate import file-name=letsencrypt.pem passphrase=""
     certificates-imported: 2
     private-keys-imported: 0
            files-imported: 1
       decryption-failures: 0
  keys-with-no-certificate: 0

For basic verification we rename and print the certifiactes. Make sure two certificates are listed.

[admin@MikroTik] > / certificate set name="ISRG-Root-X1" [ find where fingerprint="96bcec06264976f37460779acf28c5a7cfe8a3c0aae11a8ffcee05c0bddf08c6" ]

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

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

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

The configuration needs to be tweaked for your needs. Make sure not to send your mails to mail@example.com!

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

And finally load the configuration and add a scheduler.

[admin@MikroTik] > / system script run global-config
[admin@MikroTik] > / system scheduler add name=global-config start-time=startup on-event=global-config

Updating scripts

To update existing scripts just run script-updates.

[admin@MikroTik] > / system script run script-updates

Adding a script

To add a script from the repository create a configuration item first, then update scripts to fetch the source.

[admin@MikroTik] > / system script add name=check-routeros-update
[admin@MikroTik] > / system script run script-updates

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=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] > / system script add name=dhcp-to-dns
[admin@MikroTik] > / system script run script-updates
[admin@MikroTik] > / ip dhcp-server set lease-script=dhcp-to-dns [ find ]
[admin@MikroTik] > / system scheduler add name=dhcp-to-dns interval=5m on-event=dhcp-to-dns

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