[Oisf-users] [FORGED] OT ubuntu interface bonding

Many thanks to rmkml who pointed me to this old doc (2006):


This prompted me to install the ifenslave package and add

up /sbin/ifenslave bond0 eth0 eth1

to the end of the bond0 definition in /etc/network/interfaces.

It now works as expected.

The newer docs make no mention of ifenslave — my guess is that one is now expected to do it some other way but at least this works.
