>Description:
The softflowd port does not currently include an rc(8) script.

The following script supports running multiple instances of softflowd on a host with different interfaces.  Using settings such as:


softflowd_enable="YES"
softflowd_interfaces="em0 vlan2"
softflowd_em0_collector="sentinel.chi-dc.XXX:9998"
softflowd_vlan2_collector="sentinel.chi-dc.XXX:9996"


This script is based on the apache22 script and its method of building multiple instances.  It seems cleaner than the method employed by openvpn.
>How-To-Repeat:
