# Using udp-breeder to redistribute UDP traffic

# In this example we have the NOC box receiving flows from each group's 
# router and from softflowd.
# Also, each PC receives from its own router and from the lab gw
# Note: port numbers changed a bit from previous docs.

In /etc/default/softflowd:
--------------------------------------------------------------------------------------
INTERFACE="any"
OPTIONS="-n 10.10.0.250:9009 -v 5"
--------------------------------------------------------------------------------------


This goes in /etc/rc.local:
--------------------------------------------------------------------------------------
