Hey Thanos,You can only set one suppression per gid:sid pair so you can't at the moment fully exclude a gid:sid by suppression.
Are the alerts you are trying to suppress with 0:0 based on builtin rules? You may be able configure multiple policies differently to work around some cases.
Also, I'm curious about your suppression of 119:225 and 119:228. Can you share any data on those like -A cmg output or maybe a pcap?

Hello All, We are running Snort3.0.0-250 as IDS and we are trying to suppress several IP addresses from the logs (global suppression from all signatures). In order to perform this for specific IP addresses by source we add the below under snort.lua suppress = { { gid = 119, sid = 228 }, { gid = 119, sid 225 }, { gid = 0, sid =0, track = by_src, ip = '10.10.10.10', ip = '192.168.10.10' }, } My questions are: - Is there a way to use additional suppresion rules to cover by_src with the same gid and sid? - Is there a way to use additional suppresion rules to cover by_src and by_dst, to totally exluded a subnet or IP address? _______________________________________________ Snort-devel mailing list Snort-devel () lists snort org https://lists.snort.org/mailman/listinfo/snort-devel Please visit http://blog.snort.org for the latest news about Snort!
