MGA6-32 MATE on IBM Thinkpad R50e No installation issues According to the info in MCC this is a service involved in IPv6. I don't have that here, but at least the service should run OK, so at CLI: # systemctl -l status radvd ● radvd.service - Router advertisement daemon for IPv6 Loaded: loaded (/usr/lib/systemd/system/radvd.service; enabled; vendor preset: enabled) Active: inactive (dead) # systemctl start radvd # systemctl -l status radvd ● radvd.service - Router advertisement daemon for IPv6 Loaded: loaded (/usr/lib/systemd/system/radvd.service; enabled; vendor preset: enabled) Active: active (running) since di 2019-02-05 10:21:09 CET; 3s ago Process: 14000 ExecStart=/usr/sbin/radvd $OPTIONS (code=exited, status=0/SUCCESS) Main PID: 14001 (radvd) CGroup: /system.slice/radvd.service ├─14001 /usr/sbin/radvd └─14002 /usr/sbin/radvd feb 05 10:21:09 mach6.hviaene.thuis systemd[1]: Starting Router advertisement daemon for IPv6... feb 05 10:21:09 mach6.hviaene.thuis systemd[1]: Started Router advertisement daemon for IPv6. feb 05 10:21:10 mach6.hviaene.thuis radvd[14000]: [Feb 05 10:21:10] radvd (14001): eth0 not found: No feb 05 10:21:10 mach6.hviaene.thuis radvd[14001]: eth0 not found: No such device Indeed, my ethernet device is named differently here, so I change the first line of /etc/radvd.conf to "interface enps2s8", save the file and: # systemctl restart radvd # systemctl -l status radvd ● radvd.service - Router advertisement daemon for IPv6 Loaded: loaded (/usr/lib/systemd/system/radvd.service; enabled; vendor preset: enabled) Active: active (running) since di 2019-02-05 10:25:05 CET; 4s ago Process: 15130 ExecStart=/usr/sbin/radvd $OPTIONS (code=exited, status=0/SUCCESS) Main PID: 15132 (radvd) CGroup: /system.slice/radvd.service ├─15132 /usr/sbin/radvd └─15133 /usr/sbin/radvd feb 05 10:25:05 mach6.hviaene.thuis radvd[14000]: [Feb 05 10:25:05] radvd (14002): Exiting, privsep_re feb 05 10:25:05 mach6.hviaene.thuis radvd[14000]: [Feb 05 10:25:05] radvd (14002): Exiting, privsep_re feb 05 10:25:05 mach6.hviaene.thuis systemd[1]: Stopping Router advertisement daemon for IPv6... feb 05 10:25:05 mach6.hviaene.thuis systemd[1]: Stopped Router advertisement daemon for IPv6. feb 05 10:25:05 mach6.hviaene.thuis systemd[1]: Starting Router advertisement daemon for IPv6... feb 05 10:25:05 mach6.hviaene.thuis systemd[1]: Started Router advertisement daemon for IPv6.
