I have been trying to get snort IDS to work, but I having some difficulty. When I run snort -c /etc/snort/snort.conf -l /var/log/snort I keep getting this error.
Initializing rule chains... Warning: /etc/snort/rules/dos.rules(42) => threshold (in rule) is deprecated; use detection_filter instead. ERROR: /etc/snort/rules/community-virus.rules(19) => !any is not allowed
Any help would be greatly appreciated.
