External #768

Updated by Pierre-Louis Bonicoli about 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: 
 # ✅ 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). 
 # ✅ Duck: contact Acontios to provide the L2TP setup 

 The required tasks in order to update the configuration: 
 #  🔲 ensure we are able to connect through the Nerim link 
 #  🔲 remove any reference to the hivane network interface 
 <pre># rgrep -l eth-wan-hivane /etc/ 
 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) 
 #  🔲 stop the multihoming setup 
 #  🔲 run the L2TP service 
 #  🔲 start the multihoming setup 

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