Hi,
I'm wondering if anyone came across this recently, because I can't find any
bug reports or posts referring to it online (so I'm wondering if I messed
something up inadvertently).
I have a root server running Stretch 9.7 (fully upgraded) and up until last
night when I rebooted it (previous uptime 66 days and change) everything
was working fine; now, the inet6 interface is not coming up at boot.
Here's my (redacted) /etc/network/interfaces:
> auto lo
> iface lo inet loopback
> iface lo inet6 loopback
>
> auto eth0
> iface eth0 inet static
> address a.b.c.d
> netmask 255.255.255.224
> gateway c.d.e.f
> up route add -net a.b.c.x netmask 255.255.255.224 gw c.d.e.x dev eth0
> up ip addr add f.g.h.i/32 dev eth0
> down ip addr del f.g.h.i /32 dev eth0
> post-up /etc/network/iptables.sh
>
> iface eth0 inet6 static
> address 2a01:xxxx:xxxx:xxxx::2
> netmask 64
> gateway fe80::1

The server boots fine (with the exception of a plethora of error messages
and stuff that doesn't start because configured to use inet6, like
apache2), and my IPv4 comes up normally, but only the link-local IPv6
address is there, not the one in interfaces
If I use "ip -6 a a <ipv6 addr> dev eth0" and "ip -6 ro a default via
fe80::1" then it works fine.
Checking /var/log/{messages,dmesg,kern.log,daemon.log} for ipv6 only tells
me (repeatedly, at every boot):

After boot, systemctl restart networking doesn't do anything.
Someone somewhere said "try adding a pre-up sleep 10" directive for a
similar problem: it seemed to work with systemctl restart networking but
didn't do anything at boot time.
The card is
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
and up until today was using the r8169 driver; I switched to r8168-dkms but
nothing changed.
The system does not have Network Manager.
Does anyone have any suggestions?
Thanks!
Claudio
