I am new to Snort, I followed the instructions on this url: https://wwwx.cs.unc.edu/~hays/archives/work/index.php
All went well until I reached the following stage:
"Now a quick test. Run the following and see if snort runs:
sudo snort -c /etc/snort/snort.conf -i eth1"
After running the command line above, I got the following outcomes:
Running in IDS mode
--== Initializing Snort ==--
Initializing Output Plugins!
Parsing Rules file /etc/snort/snort.conf
Var 'HOME_NET' redefined
PortVar 'HTTP_PORTS' defined : [ 80 ]
PortVar 'SHELLCODE_PORTS' defined : [ 0:79 81:65535 ]
PortVar 'ORACLE_PORTS' defined : [ 1521 ]
Frag3 global config:
Initializing rule chains...
ERROR: Undefined variable name: (/etc/snort/rules/bad-traffic.rules:27): EXTERNAL_NET
Fatal Error, Quitting..
Is there anyone know what's this all about? Would you please let me know "how to" fix this "Fatal Error"? what should I do next?
Any information and help would be much appreciated.
