MikroTik CHR on VPS

Instructions for installing the MikroTik Cloud Hosted Router (CHR) on a VPS provider.

Note: You will be overwriting the existing VPS server using this guide.

Preparation

  • Spin up a VPS using a Debian based Linux distro
    • Choose one with at least one CPU and 512MB of memory. You can increase the CPU and memory as your needs/use dictates.
  • Login to VPS

Installation

  • Run the following to replace the Linux install on the VPS.

Note: Adjust the /dev/vda listed in the last line to match the actual drive used in the VPS.

  • First make sure the packages information is up to date
  apt-get update
  • Ensure unzip is installed
  apt-get install unzip
  • Then copy and run the entire block of commands below into the terminal. Verify the name of the interface in line 4 matches what your VPS uses.
  wget https://download.mikrotik.com/routeros/6.48.3/chr-6.48.3.img.zip -O chr.img.zip && \
  gunzip -c chr.img.zip > chr.img && \ 
  mount -o loop,offset=33554944 chr.img /mnt && \ 
  ADDRESS=`ip addr show ens3 | grep global | cut -d' ' -f 6 | head -n 1` && \ 
  GATEWAY=`ip route list | grep default | cut -d' ' -f 3` && \ 
  echo "/ip address add address=$ADDRESS interface=[/interface ethernet find where name=ether1] /ip route add gateway=$GATEWAY " > /mnt/rw/autorun.scr && \ 
  umount /mnt && \ 
  echo u > /proc/sysrq-trigger && \ dd if=chr.img bs=1024 of=/dev/vda
  • Once you successfully complete the above, power off (do not shut down) the VPS and then turn it back on to boot into MikroTik CHR.

Configuration

  • Login to the MikroTik CHR via the terminal using admin for the username with no password
  • Change the default admin password with:
  /user set name=admin password=<new password>

If the IP address and Gateway were not properly set at installation:


Set $ADDRESS and $GATEWAY first or replace them in the line below with the actual values.

  echo "/ip address add address=$ADDRESS interface=[/interface ethernet find where name=ether1] /ip route add gateway=$GATEWAY"
  • If the above does not work on setting the IP address and gateway properly:
    • Set IP address with: /ip address add address=<ip address> netmask=<netmask> interface=ether1
    • Set Gateway IP address with: /ip route add dst-address=0.0.0.0/0 gateway=<gateway IP>

Finishing Up

AMPRNet/44Net

You can use MikroTik devices as a way to connect to AMPRNet/44Net. Once connected, you can then setup your AllStarLink/PTTLink node with a 44Net IP address.

IPSEC

Sometimes you need to secure a link between a system and a MikroTik device.

HamWAN

Website: https://hamwan.org

"HamWAN is a non-profit organization (501c3) developing best practices for high speed amateur radio data networks. HamWAN also runs the Puget Sound Data Ring, which is a real-world network implementation of the proposed designs."

MikroTik devices are used in HamWAN type networks. Once you are connected to HamWAN, you can then setup your AllStarLink/PTTLink devices on the network.

Certified Networks

Mi6WAN

Website: https://w8cmn.net/mi6wan/

"The Mi6WAN network is our Internet Protocol (IP) Based network. Utilizing microwave, fiber and wireless connections we have built a High-Speed Point to Point and Point to Multipoint network using standards based protocols and RF gear. Our links are measured in MBPS not bps like traditional ax.25 based amateur radio based networks. We are currently allocated subnets from the AMPRNet 44/8 of 44.103/19 and 44.103.32/21. These subnets we have allocated down to our different sites for the needs of our network. We primarily transport data in support of our other projects as IP is becoming more and more the standard to transport audio/video/data."

For those located within the Central Michigan area, you can connect to a HamWAN like network and receive an AMPRNet/44Net IP address for use with your AllStarLink/PTTLink nodes.
