Re: Help! An error about "reject" action with build261

I had such problem. For me It's enough  to specify is active.device = "ip |
ethN" . Minimally.

Hi all,

       I start snort(build261) failed  with reject = { } in  snort.lua,
and the error is as follow  .    But it can be done successfully with snort
version of build 250.

       The error is as follow:

        FATAL: Active response: can't open
        Fatal Error, Quitting..

       After my debuging , I found when add the follow config to snort.lua
can resolve the above erro with reject = {}:
active =
{
attempts = 2,
device = "eth0",
dst_mac = "00:06:76:DD:5F:E3",
}
The snort3_manual says:dst_mac will change response destination MAC
address, if the device is eth0, eth1, eth2 etc. Otherwise, response
destination MAC address is derived from packet.
 What is more important, I do not want to set a fixed MAC address rather
than want the response destination MAC address is derived from packet.
So How to resolve it?
 Another question, what is difference between  reject and reset as rule
action ?
