Package: suricata
Version: 2.0.7-2
Severity: important
Hi,
I have a problem with suricata after upgrading to jessie. It seems that http
rules are no longer work after upgrade to jessie.
I have created 2 rules to make a test in a file /etc/suricata/rules/local.rules:
alert http any any -> any any (msg:"User-Agent Gecko http_user_agent";
content:"Gecko"; http_user_agent; sid:2; rev:1;)
alert ip any any -> any any (msg:"ICMP detected"; sid:3; rev:1;)
In the log file (/var/log/fast.log) I can see the rule based on the ip test
(and other alerts but no http alert):
04/28/2015-21:44:10.119672 [**] [1:3:1] ICMP detected [**] [Classification:
(null)] [Priority: 3] {TCP} 192.168.0.119:4996 -> 168.61.34.65:80
I use the rules from Emerging Threats
(https://rules.emergingthreats.net/open/suricata-2.0/emerging.rules.tar.gz).
There is no error in suricata starting:
