Created attachment 5736 [details] proposed patch, slightly tested The interfaces are only created after /sbin/sysctl is run: # screendump Setting kernel variables ...error: "net.ipv6.conf.br0.accept_ra" is an unknown key error: "net.ipv6.conf.XXXlandev0.accept_ra" is an unknown key error: "net.ipv6.conf.dhcppt0.accept_ra" is an unknown key error: "net.ipv6.conf.nfslan0.accept_ra" is an unknown key error: "net.ipv6.conf.XXXlan0.accept_ra" is an unknown key error: "net.ipv6.conf.XXXlanprod0.accept_ra" is an unknown key error: "net.ipv6.conf.XXXlanint0.accept_ra" is an unknown key error: "net.ipv6.conf.tslan0.accept_ra" is an unknown key failed. ...

Setting "net.ipv6.conf.*.accept_ra" should be removed from "/etc/univention/templates/files/etc/sysctl.d/local.conf", as it is only executed once during server boot. It should be converted to writing an "up sysctl -w ...=[01]" line in /etc/network/interfaces, which is executed when the interface if brought up, whi univention-system-setup
Created attachment 5737 [details] proposed patch v2, slightly tested Add "-q" to "sysctl -w".
There is a Customer ID set so I set the flag "Enterprise Customer affected".
