Re: [Snort-openappid] Snort IPS with openappid not able to block webpages

I think i got what is the error but unable to solve it. I already pasted
all logs in first mail. In the snort logs you can see

*Snort logs:*
navneet@navneet:~$ sudo snort -d -A console -u snort -g snort -c
/etc/snort/snort.conf -i eth0:wlan0 -Q
Enabling inline operation
Running in IDS mode


*It is running in IDS mode even after enabling inline operations*

I also pasted conf file there. I think it is now much simple for all of you
now. I am new in squid and following documentation to install snort. Also
giving link for those documentation

https://www.snort.org/documents/snort-ips-tutorial
https://www.snort.org/documents/snort-ips-using-daq-afpacket

Waiting for help

Hi Costas/Y M

Thanks for your quick response.

Costas I tried to run snort with -k option, but it was not working so I
think it is not related to checksum error.
Y M I added snort.conf in previous mail. I think i have configured daq and
afpacket as inline, and normalization support too. Also when I pasted the
logs here I was trying with a long appid rule, i tried with a single filter
for appid too, but was getting same result as i told in previous mail

What are your Snort policy mode and afpacket daq configurations? Try
settings these to support inline operations. Is normalization also
configured?

You also have a warning about exceeding the max. number of allowed
appid's per rule. While this may be unrelated, it may be something to watch
for.

Hi All,

I am testing snort 2.9.7.6 with openappid on ubuntu 14.04 amd64 system as
IPS using daq afpacket inline mode. But when i add rule for dropping
packets as per appid filter, some filters do block webpages such as https
appid filter blocks all https, some don't block like nbc appid filter and
some just block for sometime till i refresh the webpage.

Here i tested with linkedin site, the log shows drop but i was able to
browse it.

Here are following logs:
