External #768

Updated by Pierre-Louis Bonicoli about 1 year ago

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. 🔲 Pilou: If any issue occurs during the migration, a physical access will be required: ask 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:
# 3. 🔲 ensure we are able to connect through the Nerim link
# 4. 🔲 remove any reference to the hivane network interface
<pre># <pre>
rgrep -l eth-wan-hivane /etc/
/etc/sysctl.d/90-disable-accept_ra.conf</pre> /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)
# 5. 🔲 stop the multihoming setup
# 6. 🔲 run the L2TP service
# 7. 🔲 start the multihoming setup

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