# Let's Encrypt RouterOS / Mikrotik
|
|
**Let's Encrypt certificates for RouterOS / Mikrotik**
|
|
|
|
### How it's works:
|
|
* When you renew your certificates using CertBot
|
|
* The script connects to your RouterOS / Mikrotik using DSA Key
|
|
* Delete previous certificate files
|
|
* Delete previous certificate
|
|
* Upload two new files: Certificate and Key
|
|
* Import new certificate and key
|
|
* Change SSTP Server Settings to new certificate
|
|
* Delete certificate and key files form RouterOS / Mikrotik storage
|
|
|
|
### Installation on Ubuntu 16.04
|
|
*Similar way you can use on Debian/CentOS/AMI Linux/Arch/Others*
|
|
|
|
Download the repo to your system
|
|
```sh
|
|
sudo -s
|
|
cd /opt
|
|
git clone https://github.com/gitpel/letsencrypt-routeros
|
|
```
|
|
Edit the settings file:
|
|
```sh
|
|
vim /opt/letsencrypt-routeros/letsencrypt-routeros.settings
|
|
```
|
|
| Variable Name | Data |
|
|
| ------ | ------ |
|
|
| ROUTEROS_USER | admin |
|
|
| ROUTEROS_HOST | 10.0.254.254 |
|
|
| ROUTEROS_SSH_PORT | 22 |
|
|
| ROUTEROS_PRIVATE_KEY | /opt/letsencrypt-routeros/id_dsa |
|
|
| DOMAIN | router.mydomain.com |
|
|
|
|
Change permissions:
|
|
```sh
|
|
chmod +x /opt/letsencrypt-routeros/letsencrypt-routeros.sh
|
|
```
|
|
Generate DSA Key for RouterOS
|
|
|
|
*Make sure to leave the passphrase blank (-N "")*
|
|
|
|
```sh
|
|
ssh-keygen -t dsa -f /opt/letsencrypt-routeros/id_dsa -N ""
|
|
```
|
|
|
|
Send Generated DSA Key to RouterOS / Mikrotik
|
|
```sh
|
|
source /opt/letsencrypt-routeros/letsencrypt-routeros.settings
|
|
scp -P $ROUTEROS_SSH_PORT /opt/letsencrypt-routeros/id_dsa.pub "$ROUTEROS_USER"@"$ROUTEROS_HOST":"id_dsa.pub"
|
|
```
|
|
|
|
### Setup RouterOS / Mikrotik side
|
|
*Check that user is the same as in the settings file letsencrypt-routeros.settings*
|
|
|
|
*Check mikrotik ssh port in /ip services ssh*
|
|
|
|
*Check mikrotik firewall to accept on SSH port*
|
|
```sh
|
|
:put "Enable SSH"
|
|
/ip service enable ssh
|
|
|
|
:put "Add to the user DSA Public Key"
|
|
/user ssh-keys import user=admin public-key-file=id_dsa.pub
|
|
```
|
|
|
|
### CertBot Let's Encrypt
|
|
Install CertBot using official manuals https://certbot.eff.org/#ubuntuxenial-other
|
|
|
|
*for Ubuntu 16.04*
|
|
```sh
|
|
apt update
|
|
apt install software-properties-common -y
|
|
add-apt-repository ppa:certbot/certbot
|
|
apt update
|
|
apt install certbot -y
|
|
```
|
|
|
|
***In the first time you will need to create Certificates manually and put domain TXT record***
|
|
|
|
*follow CertBot instructions*
|
|
```sh
|
|
source /opt/letsencrypt-routeros/letsencrypt-routeros.settings
|
|
certbot certonly --preferred-challenges=dns --manual -d $DOMAIN --manual-public-ip-logging-ok
|
|
```
|
|
|
|
### Usage of the script
|
|
*To use settings form the settings file:*
|
|
```sh
|
|
./opt/letsencrypt-routeros/letsencrypt-routeros.sh
|
|
```
|
|
*To use script without settings file:*
|
|
|
|
```sh
|
|
./opt/letsencrypt-routeros/letsencrypt-routeros.sh [RouterOS User] [RouterOS Host] [SSH Port] [SSH Private Key] [Domain]
|
|
```
|
|
*To use script with CertBot hooks:*
|
|
```sh
|
|
certbot certonly --preferred-challenges=dns --manual -d $DOMAIN --manual-public-ip-logging-ok --post-hook /opt/letsencrypt-routeros/letsencrypt-routeros.sh
|
|
```
