Description

On Toushirou, the current link provided by Acontios will end in one week (2022-04-14).

According to the checks made by Acontios about the used bandwith, the Nerim link can be used instead of the current one.

A L2TP tunnel will be required in order to keep/use our current IP.

The requirements:
  1. ✅ If any issue occurs during the migration, a physical access will be required
    • Pilou asked Chojin about it (Pilou will be available 2022-04-11 or 2022-04-13).
  2. ✅ Duck: contact Acontios to provide the L2TP setup
The required tasks in order to update the configuration:
  1. ✅ ensure we are able to connect through the Nerim link
  2. ✅ remove any reference to the hivane network interface
    # rgrep -l eth-wan-hivane /etc/
    /etc/network/interfaces.d/hivane-link
    /etc/network/multihoming
    /etc/default/grub
    /etc/systemd/network/10_eth-wan-hivane.link
    /etc/mp-admin/firewalling
    /etc/sysctl.d/90-disable-accept_ra.conf

    Notes that the following services aren't listening on nerim IP:
    • slapd (TCP ports 389 and 636)
    • apache2 (TCP ports 80 and 443)
    • proftpd (TCP port 21)
  3. ✅ stop the multihoming setup
  4. ✅ run the L2TP service
  5. ✅ start the multihoming setup

poulet: I have checked that SSH is listening on the IP provided by Nerim (213.215.11.165)
