Could I please know why I keep getting ... "responding! TCP[2] IP[0] UDP[0]" a million times on my screen everytime I run snort on a traffic data file? Its like that statement runs in some sort of a never ending loop. Please could I know why this is happening and how do I stop this from happening. Is there any option that goes with my snort command line
Are you sure that the message isn't "returning" instead? If it is... Snort is telling you that something isn't right on your network. You've got something creating packets with bad checksums. If you take a look at lines 88-103 in src/detect.c you'll see this: 88 /* 89 * If the packet has an invalid checksum marked, throw that 90 * traffic away as no end host should accept it. 91 * 92 * This can be disabled by config checksum_mode: none 93 */ 94 95 if(p->csum_flags) 96 { 97 printf("returning! TCP (%d) IP (%d) UDP (%d) \n", 98 (p->csum_flags & CSE_TCP), 99 (p->csum_flags & CSE_IP), 100 (p->csum_flags & CSE_UDP) 101 ); 102 return 0; 103 } Does that help?
