A couple things to try: 1) Have you confirmed your dag is configured, up, and running how you'd expect? Check dagconfig to make sure it is receiving (and dropping) packets on all the interfaces you'd expect. Then, attach tcpdump to one of the streams and confirm that it is working. 2) Confirm your initscript is trying to attach to separate dag stream as network interfaces. The debug information you provided here is sparse but it claims it doesn't have permission to attach to /dev/dag0. I'm not sure if this is an artifact of what DAQ is doing behind the scenes but that isn't where I'd expect the data acquisition stack to connect. It should be attaching to a network interface such as dag0:0. What is the invocation line for snort in your script? On Thu, Nov 13, 2014 at 1:41 PM, test engineer <test12524 () gmail com> wrote:
Posting this again under specific subject of Emulex DAG Still unsuccessful in getting the SNORT init.d script to work using an Emulex DAG card. I have modified the scrip and it works just fine when executed via command line (/etc/init.d/snort {start|stop|restart} but when executed at boot the error in the messages file is: .... snort [2440] Daemon initialized, signaled parent pid: 2439 snort [2440] Reload thread starting... snort [2440] Reload thread started, thread 0x7fc5c404e700 (2441) snort [2440] FATAL ERROR: Can't start DAQ (-1) -dag_open /dev/dag0: Permission denied.
