Snare on Debian and Ubuntu

_____________________________________________________________________________________

Snare installation in Ubuntu:
----------------------------
Snare installation in Fedora/Redhat distribution is very easy and there are many documents for help. But i could not find single complete document so i spent few days for successful working of Snare in Ubuntu linux :)

--------------------------------------------------------------------------------------------------------

Steps for usage of Snare on Ubuntu/debian (I tested it on Ubuntu12.04)

-> Install auditd ,libaudit-dev ,libaudit0
-> install selinux
-> i also installed system-config-audit (Graphical utility for editing audit config)

Download SnareLinux from sourceforge and then install it.
commands:
1. make
2. ./Install.sh

it will create files under /usr/sbin and /etc directories

contents of /etc/snare.conf file :

******START*** [Remote]
allow=1
listen_port=6161 [Output]
network=127.0.0.1:6161

****END******

tcp_client_max_idle = 0
enable_krb5 = no
krb5_principal = auditd

contents of audit.rules file

****START***
-e 1
-f 1
-b 8192
-r 0

-a task,always
-a user,always******END***

Note: plz verify that 6161 is in listen mode

tcp 0 0 0.0.0.0:6161 0.0.0.0:* LISTEN
Hopefully this will be usefull.
