Hello, I recently installed demo package of disk2n after failed using pfsend for generating traffic with a very large pcap file. Installation was successful but when I tried to run disk2n it fails: disk2n -i dna0 -p 8 -f file.cap12/Dec/2014 17:49:43 [disk2n.c:2018] WARNING: Invalid license found for E9F3843D9105A1EF [Missing license file]12/Dec/2014 17:49:43 [disk2n.c:2260] WARNING: ***************************************************12/Dec/2014 17:49:43 [disk2n.c:2261] WARNING: ** **12/Dec/2014 17:49:43 [disk2n.c:2262] WARNING: ** Switching to DEMO MODE due to license error **12/Dec/2014 17:49:43 [disk2n.c:2263] WARNING: ** **12/Dec/2014 17:49:43 [disk2n.c:2264] WARNING: ***************************************************12/Dec/2014 17:49:43 [disk2n.c:2265] WARNING: ** Replaying will stop after 5 min **12/Dec/2014 17:49:43 [disk2n.c:2267] WARNING: ***************************************************12/Dec/2014 17:49:43 [disk2n.c:2352] Welcome to disk2n v.2.3.141203 (4553)12/Dec/2014 17:49:43 [disk2n.c:2380] Reading data in 64 KB chunks12/Dec/2014 17:49:43 [disk2n.c:2381] Allocating 64 MB buffer memory...12/Dec/2014 17:49:44 [disk2n.c:2432] Memory allocated successfully12/Dec/2014 17:49:44 [disk2n.c:1822] ERROR: Unable to open PF_RING device dna0 [globals.ro.snaplen=1536]12/Dec/2014 17:49:44 [disk2n.c:314] Waiting thread termination...12/Dec/2014 17:49:44 [disk2n.c:2440] ERROR: Unable to initialize socket on dna0 I'm still able to use pfsend for sending small pcap files.
