I've installed "Snort" on FreeBSD-9.1 (32-bit) from the standard ports using:
pkg_add -r snort
After configuring and running with:
snort -c /etc/snort/snort.conf -A full -u snort -g snort -i em1 -T
I'm getting this error:
ERROR: /etc/snort/snort.conf(337) Unknown preprocessor: "ftp_telnet".
Doing some search on the Internet, the only thing I found is that this could happen if I'm using a
snort.conf with a different version from snort itself, but this is not my case. My snort version is:
,,_ -*> Snort! <*- o" )~ Version 22.214.171.124 IPv6 GRE (Build 40) '''' By Martin Roesch & The Snort Team: http://www.snort.org/snort/snort-team Copyright (C) 1998-2012 Sourcefire, Inc., et al. Using libpcap version 1.3.0 Using PCRE version: 8.31 2012-07-06 Using ZLIB version: 1.2.7
and I'm using
snortrules-snapshot-2931.tar.gz from snort.org.
I've had some previous experience installing and running snort on Linux and I never faced such errors, but I'm fairly new to BSD-UNIX.
Can anyone help?
