Title: 22.1.9 - DHCPv6 PPPoE Issues
Post by: shadesh on July 07, 2022, 09:35:19 AM
Hi,

I know that there are plenty problems with this combination but mine should be "fixable".
Every night I found out that my PPPoE goes down, maybe because of the forced disconnect by Telekom Deutschland, anyway after this disconnect it seems DHCPv6 are not longer working. Is somehow alive:

root@gw:~ # ps auxww | grep dhcp
root 85069   0.0  0.1  12796   2244  -  Is   08:38       0:00.14 /usr/local/sbin/dhcp6c -c /var/etc/dhcp6c.conf -p /var/run/dhcp6c.pid


But the web interface shows a red stop sign and its not possible to start it from there. The only way to bring it back to life is to kill it and start it again both via CLI.

root@gw:~ # kill -15 85069

root@gw:~ # ps auxww | grep dhcp
root 50303   0.0  0.0    432    248  0  R+   08:21       0:00.00 grep dhcp

root@gw:~ # /usr/local/sbin/dhcp6c -c /var/etc/dhcp6c.conf -p /var/run/dhcp6c.pid

The relevant log just stops here:
