dynamic (so) rules

[chris ryan <chris.ryan () gmx de>]

Hi,

i've just compiled the so-rules with snort 2.8.2.1 from the latest
tarball. Some default rule files where included, too.

I set the SNORT_VERSION in the makefile to 2.8.1.

When i compile the modules in the /src directory, some new rule files
were created. The only include a subset of the default rules in the
upper directory, ie:

generated bad-traffic.rules  (in /src)
---------------------------
# Autogenerated skeleton rules file.  Do NOT edit by hand
alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"BAD-TRAFFIC linux ICMP
header dos attempt"; sid:13307; ...
alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"BAD-TRAFFIC PGM nak
list overflow attempt"; sid:8351; ...


default bad-traffic.rules from tarball:
---------------------------------------
# Autogenerated skeleton rules file.  Do NOT edit by hand
alert udp any 53 <> any any (msg:"BAD-TRAFFIC dns cache poisoning
attempt"; ...
alert udp $HOME_NET 67 <> $HOME_NET 68 (msg:"BAD-TRAFFIC invalid dhcp
offer denial of service attempt"; ...
alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"BAD-TRAFFIC linux ICMP
header dos attempt"; ...
alert ip any any <> any any (msg:"BAD-TRAFFIC Windows remote kernel
tcp/ip igmp vulnerability exploit attempt"; ...
alert icmp $HOME_NET any <> 224.0.0.1 any (msg:"BAD-TRAFFIC Windows
remote kernel tcp/ip icmp vulnerability exploit attempt";
alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"BAD-TRAFFIC PGM nak
list overflow attempt"; ...


I guess it has sth. to do with my snort.conf or makefile.
Just for curiosity, can anybody explain that to me?


Thanks in advance, Chris.

PS: there is a "web-misc" in the libs section of the makefile with has
no corresponding files in the tarball
