so early reply to thank you.
configutate and exec right now.
but result unchangeble.

Just because you have the icmp.rules enabled does not mean you are
alerting on every ping request.  There is not a signature in the default
icmp.rules file that fires on every ping.


1. /etc/snort/snort.conf has changed

(omission of part)

#=========================================
# Include all relevant rulesets here
#
# shellcode, policy, info, backdoor, and virus rulesets are
# disabled by default.  These require tuning and maintance.
# Please read the included specific file for more information.
#=========================================

(omission of part)

include $RULE_PATH/icmp.rules
↓
# include $RULE_PATH/icmp.rules

need change other configration.?

2.# snort -c /etc/snort/snort.conf (RETURN)
  # ping eth0 address (RETURN)
  # CTRL+C (RETURN)
