Hi
remove the all the "http_header" from that line of code
http://archives.neohapsis.com/archives/snort/2009-03/0030.html
If that fails,comment out the line
there is a solution from an older post,
https://www.experts-exchange.com/questions/24481471/Installed-Snort-engine-working-well-but-errors-with-downloaded-rules.html
it mentions to use "build from ports", but i do not understand what that means
Also, make sure to have latest stable release

thanks. I was having issues with netbios.rules too. I commented out that stuff and now it works. Why are these rules buggy
Thanks
Thanks
got to that web-misc.rules and edit out line 533 with a # at the beginning of line 533
please copy the entire string and post here
