Need help with softflowd

[vlord]

I have Merlin's .354.29 build and am having trouble getting softflowd to run as a daemon. I can get it to run in debug form but not otherwise. Any suggestions? Ultimately I'll be forwarding the data to a netflow analyzer but need help with baby steps.

I had the same problem so I cheated

just run it with -d and background the task with &

so

>softflowd -i br0 -n 192.168.1.xx:2055 -m 1600 -d &

The way I actually use it is at boot time by creating the file /opt/etc/init.d/S29softflow with the following contents;

#!/bin/sh

ENABLED=yes
PROCS=softflowd
ARGS="-i br0 -n 192.168.1.xx:2055 -m 16000 -d"
PREARGS=""
DESC=$PROCS
PATH=/opt/sbin:/opt/bin:/opt/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

. /opt/etc/init.d/rc.func

I noticed that you aren't calling out the netflow version but my real question is the call at the end of your script for rc.func - what is that doing? Doesn't exist on my router.

Stumbled across this thread while googling what sounds like the same issue you had - can't get softflowd to run on it's own without using the '-d' switch. Who knows if you're still on the forums.....and it's been years now, but did you end up getting this working?
