External #768
Updated by Pierre-Louis Bonicoli over 2 years 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/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</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) </pre> # 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 (@213.215.11.165@)
