Dear Rmkml, Thanks for your comment command line with " -k none" added. And then it is totally working. So let us close the topic. Thanks again all of you for your help. ########### /usr/local/snort/bin/snort -c /usr/local/snort/etc/snort.conf-k none
ignore my previous if "-k none" is working for you... [@ALL] why is this "-k none" suddenly needed more and more in recent months?? we've never used it in any of our snort installations... is it special to a certain set of NICs?? [/@ALL]
