[ixpmanager] peering matrix and memcached

[Nick Hilliard]

Brian,

our sflow box runs freebsd, which includes sflowtool in the standard
package repository.  The package includes its own startup script.

All we need to do to get the fanout process started is use the standard
startup mechanism:

> sflow:/home/nick# grep ^sflow /etc/rc.conf
> sflowtool_enable="YES"
> sflowtool_flags="-4 -p 6343 -f 127.0.0.1/5500 -f 127.0.0.1/5501"
> sflow:/home/nick# service sflowtool start
> Starting sflowtool.
> sflow:/home/nick# 

Looks like you can add things into /etc/rc.local on ubuntu:

It would be helpful if sflowtool were packagised on ubuntu, but it looks
like Rowan's PR wasn't accepted.
