Package: ifupdown
Version: 0.8.35
Severity: normal
Dear Maintainer,
After upgrading to Debian 10 "buster" the virtual interface was misconfigured
and could not be brought up manually.
In "/etc/network/interfaces" were the following stanzas (IP addresses redacted):
allow-hotplug eth0
iface eth0 inet static
address AAA.AAA.AAA.AAA
netmask 255.255.255.0
network AAA.AAA.AAA.0
broadcast AAA.AAA.AAA.255
gateway AAA.AAA.AAA.
allow-hotplug eth1
iface eth1 inet static
address 172.16.BBB.BBB
netmask 255.255.0.0
This is for a server in a data center with a public-facing IP address on eth0
and a private (RFC1918) IP address for unmetered use within the data center for
backups and other internal operations. The server is itself a QEMU virtual
instance under a KVM hypervisor.
After upgrade, no errors were reported but the eth1 interface could not be
brought up either automatically on boot or manually after boot. The eth0
interface worked as expected.
A workaround was to change "eth1" to "eth0.1" in the "interfaces" file, but
it is not clear whether this satisfies the requirement of the data center for
traffic on the private network to by unmetered. Regardless, some sort of
warning rather than silent failure should occur on upgrade.
