Hi,

I am new with snort. I am currently running it with Endian firewall in
front of our email server, for a month everything seems ok but since
yesterday I am facing issue when I enabled snort from the the intrusion
detection.

It blocks POP, IMAP and RDP but it shows from the live logs that it was
allowed. I have also all these warnings.

Jul 20 23:57:05 syslog-ng[2372] WARNING: Configuration file format is too
old, syslog-ng is running in compatibility mode Please update it to use the
syslog-ng 3.5 format at your time of convinience, compatibility mode can

please review the warnings about incompatible changes printed by syslog-ng,
and once completed change the @version header at the top of the

Please advise. thanks.

The actual error messages should show up a little earlier while loading
the config. If you scroll up in Snort output, do you see the error message?

It seems to be complaining about your appMapping.data in your ODP (with
what looks to be an odd line in it). Which ODP are you using? Did you
modify it at all? Anything odd looking in it (each line should basically
look the same with a comma-separated list of strings and numbers)? Anything
odd about how you configured it? I don't suppose we can get the file...

The error is unrelated to the search engine.  It is coming from appid.
Double check your appid config.  Mike may be able to give you some
advice on that.  We'll change the output to make that more clear.

Correction: The entries in that file are tab-delineated (my fingers got
ahead of my brain).

In the appMapping.data file that you shared with me, it looks like the
very first line is "bogus" (the one that doesn't look like any other line).
I just downloaded it myself, and I see the same issue that you see.
Somewhere along the way, we must have started including a bad line at the
top of that file. We will work on getting that resolved.

Also, it looks like Snort2 and Snort3 AppIDs have a difference stance on
the fatalness of bad app entries. We'll work on resolving that as well (and
make a clearer message).

In the meantime, you should be able to just remove that first line, and it
should work just fine. So, delete this line at the top (it shouldn't be
there):

Subject: [Snort-users] recommended approach for multi-instance Snort
I have a reasonably capable Dell R740 with Intel XL710 2x40Gbps NIC to
do Snort performance testing on. Is there a general consensus on the
best approach (i.e. highest throughput) for doing multi-instance Snort
(v2.9.11.1)?

The options I see are:

  - PF_RING
  - DPDK
  - something else?

I'm assuming using OVS and Snort VMs would have lower performance
because of the potential bottledneck of OVS and overhead of KVM.

Intel(R) Xeon(R) Gold 6138 CPU @ 2.00GHz
Thread(s) per core:    2
Core(s) per socket:    20
Socket(s):             2

I have had the same AppID message but it never caused Snort to error out
or quit. I just considered it a warning. Output of Snort running against a
pcap is attached just in case if it helps.
