I highly recommend that you go ahead and change your oinkcode (like right now), do not post it in public!
To answer your questions:
- It depends on how you configure PulledPork: either all to one file (snort.rules) or you copy over the individual
rules files. PulledPork handles all of that.- If you do not do the modification in PulledPork's modifysid.conf, then
all of your changes will get overwritten.- We will need to see how you are configuring PulledPork (minus your oinkcode).

Subject: Re: [Snort-users] configuring rules
I have set up pulled pork and would like to know
·
where all the rules get written to
·
what happens if I modify one of these rules and run the command again
·
why when I empty the rules folder and run the pulledpork command the folder is still empty
[root@snort snort]# pulledpork.pl -c /etc/pulledpork/pulledpork.conf -vv

It appears that all of your rules are bi-directional. “<>”. Try making them single directional “->”

Hello
I needs some help in writing some rules to test my network.
I have set up snort, barnyard2, snorby on centos 7
My home network is
ipvar HOME_NET
[172.16.0.0/22,172.16.12.0/24,172.16.13.0/24,31.221.13.192/29,62.49.167.0/29,62.49.167.8/29,192.168.254.0/24,192.168.202.0/24,192.168.218.0/24,10.0.2.0/24,10.0.3.0/24,192.168.15.0/24,172.16.64.0/18,172.16.15.0/24,172.16.16.0/22,10.0.0.0/24,10.0.1.0/24,192.168.252.0/24,172.16.171.0/24,10.40.135.0/24,172.16.8.0/24,172.16.9.0/24,192.168.0.0/24,172.0.0.0/24,105.0.0.0/24,192.168.1.1/24,192.168.224.0/20,212.103.166.96/30]
The following are some test rules which I put in local.rules
alert icmp !$HOME_NET any <> $HOME_NET any (msg:"ICMP"; sid: 1000001; rev:1;) # external ping to internal network?
alert tcp $HOME_NET any <> $HOME_NET any (content:"|00 01 86 a5|"; msg:"mountd access";sid:1000002;rev:1;) # found a
sample online which has not responded to anything
alert tcp !$HOME_NET :139 <> $HOME_NET any (msg:"NetBIOS Session";sid:1000003;rev:1;) # test external ip trying to mount
alert tcp !$HOME_NET :445 <> $HOME_NET any (msg:"SMB over TCP";sid:1000004;rev:1;) # test external ip trying to mount
Have I written them correctly?
For my samba alerts I have found it also includes internal network, when I look at the source port on snorby, its not
always 139 or 445. What am I doing wrong?
