IMHO, absolutely not... if you are getting oversize reports like that, you can increase the size of your oversize_dir_length setting in the http_inspect preprocessor section of your snort.conf file... we use 750 here but you may need a larger or smaller value depending on the traffic on your network... thanks i have removed 0.0.0.0 from home net now how can i stop alerts from ip dst 0.0.0.0 How is traffic from 0.0.0.0 transversing the network? That’s what I want to know. -- Joel Esler Manager, Threat Intelligence Team & Open Source Talos Group http://www.talosintel.com
