Make sure you actually test that it functions. In previous versions of
snort I had issues where snort did not error, but only one of my
suppression was actually working. I think I had this issue early in
the 2.8 branch, but I do not remember for sure.

Hi,



I’m doing this and it works:



suppress gen_id 1, sig_id 2009955, track by_dst, ip
[172.16.1.120,172.16.1.121]



with Snort v.2.8.5.3



and I tested your suppress line and it worked for me as well (snort -T), no
error message.

Subject: [Snort-users] Using suppress and syntax



Hello Everyone,



I want to suppress a rule for a number of servers.

Can I do that?

I tried this an it gives me a parsing error:

suppress gen_id 1, sig_id 469, track by_dst, ip
[10.106.88.29,10.102.128.1,10.103.128.2,172.17.17.150]

Also,

What would be the proper syntax for the the last line show here:

var ENT_DNS_SERVERS [10.101.1.1,10.103.1.2,10.105.3.4]

var LOCAL_DNS_SERVERS [172.6.5.4,172.8.7.3,172.6.6.6]

var DNS_SERVERS [$ENT_DNS_SERVERS,$LOCAL_DNS_SERVERS]  <--- is this correct?
snort doesn't complain



Thanks

Bill
