I need to renew the lease of a certain SLES12 box. The machine is configured to use IPv6 only and so far I have tried the following:
From here:
dhclient6 -r -v eth0 && rm /var/lib/dhcp6/dhclient* ; dhclient6 -v eth0
Other attempts:
rm /var/lib/wicked/duid.xml /var/lib/wicked/lease-eth0-dhcp-ipv6.xml
rm /run/wicked/leasinfo.eth0.dhcp.ipv6 /run/wicked/state-2.xml
service network restart
After the restart in the above all files get restored as if nothing have happened.
If I do dhclient6 -r -v eth0 and then dhclient6 -v eth0 the below messages get repeated forever:
DHCPDISCOVER on eth0 ...
DHCPOFFER from ...
DHCPREQUEST on eth0 ...
DHCPACK from ...
DHCPDECLINE on eth0 ...
The settings in /etc/sysconfig/network/ifcfg-eth0 are:
BOOTPROTO='dhcp6'
DHCLIENT6_MODE=managed
DHCPV6C=yes
IPV6INIT=yes
STARTMODE=auto
DEVICE=eth0
TYPE=ethernet
It is desirable that no additional tools are installed on the machine. Any thoughts?
