This is a WIP
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. As root:
modprobe bonding mode=balance-rr miimon=100
Linking two Pandoras
- You need two USB cables and two Pandoras.
- Disable the Network Manager
- Link them together.
- Disable the USB charge on both, as root:
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
