About bonding

  • From Wikipedia:

"Link aggregation describe various methods of combining (aggregating) multiple network connections in parallel to increase throughput beyond what a single connection could sustain, and to provide redundancy in case one of the links fails."

  • It's not an addition of the bandwidth, it's a combination.

Is it useful on the Pandora ?

  • Short answer: not really.
  • Long answer: can be useful on very particular cases, like many access to RAM-cached data.
  • As always, it's fun and instructive.

ifenslave

  • This program has to be compiled. It's in the kernel sources. Will provide it sooner or later.

Kernel

  • For now, the kernel have to be recompiled to enable this feature. I will provide one sooner or later.

Module loading

  • The kernel module has to be loaded on each bonded Linux device. As root:
modprobe bonding mode=balance-rr miimon=100

Linking two Pandoras

echo 0 > /sys/class/power_supply/twl4030_usb/enable
  • Create the bonded interface:
ifconfig bond0 up
  • Add the two USB ports to the bond:
ifenslave bond0 usb0
ifenslave bond0 usb1
  • Give a fixed IP address to the bond0 of each Pandora, ie:

ifconfig bond0 10.0.0.1 and on the other OP: ifconfig bond0 10.0.0.2
