Package: isc-dhcp-relay
Version: 4.3.5-3+deb9u1
Severity: important
Tags: ipv6, upstream
Forwarded: https://gitlab.isc.org/isc-projects/dhcp/-/issues/204
Hi there,
I've been hitted by this bug on a machine running stretch, but it is
also present in the current version on sid (4.4.1-3).
dchrelay -6 doesn't start if there are interface aliases up in the
system:
# /usr/sbin/dhcrelay -6 -pf /var/run/dhcrelay6.pid -l vlan.881 -u
2001:db8:cafe::2%vlan.880

exiting.
The above error can be reproduced with inside a container with the
following /etc/network/interfaces:
auto lo
iface lo inet loopback
auto vlan
iface vlan inet dhcp
auto vlan.880
auto vlan.880:0
iface vlan.880 inet static
address 192.168.133.1/24
iface vlan.880 inet6 static
address 2001:db8:cafe::1/64
iface vlan.880:0 inet static
address 10.0.133.1/16
auto vlan.881
auto vlan.881:0
iface vlan.881 inet static
address 192.168.131.1/24
iface vlan.881 inet6 static
address 2001:db8:cafe:1::1/64
iface vlan.881:0 inet static
address 10.1.131.1/16
Just removing (or commenting out) the interface aliases entries makes
dchrelay -6 happy again.
Please note the -l and -u filters do not work. But that's another bug.
Cheers,
