Jason,

Thank you for your reply.

It is already disabled.

arkam@Arkam:~$ ethtool --show-offload eth0 | grep -i check

2 bucks says it is checksums.... disable checksum checking if running
on the same system as you are trying to test from but be aware that it
creates evasion opportunities. Alternatively you can disable checksum
offload.

Guys,

I am facing an issue with snort. I installed snort and checked the config
file with Snort -v and Snort -T etc and it was fine. Then I added a rule

for

icmp in local rules file. Started snort and no error.

Tried the following

a- Pinging another PC from the Guest running snort
b- Self Pinging on my eth0 port(The one on which snort listens)
c- Pinging this from another PC

Nothing gets written to log or U2 File.

Even with snort -U Console it just says it is processing packets stuff

but

nothing is shown.

Why it is not capturing this ICMP Alert.
**********************************************************

Some Useful Info. Here is my rule



___________________________________________________________________________

arkam@Arkam:~$ grep -i icmp /etc/snort/rules/local.rules

alert icmp any any -> 192.168.88.131/24 any ( msg:"ICMP test Detected";
GID:1; sid:10000001; rev:001; classtype:icmp-event;)
