-# FTP - File Transfer Protocol - RFC 959
-# Pattern attributes: great notsofast fast
-# Protocol groups: document_retrieval ietf_internet_standard
-# Wiki: http://protocolinfo.org/wiki/FTP
-# Copyright (C) 2008 Matthew Strait, Ethan Sommer; See ../LICENSE
-#
-# Usually runs on port 21.  Note that the data stream is on a dynamically
-# assigned port, which means that you will need the FTP connection 
-# tracking module in your kernel to usefully match FTP data transfers.
-# 
-# This pattern is well tested.
-#
-# Handles the first two things a server should say:
-#
-# First, the server says it's ready by sending "220".  Most servers say 
-# something after 220, even though they don't have to, and it usually 
-# includes the string "ftp" (l7-filter is case insensitive). This 
-# includes proftpd, vsftpd, wuftpd, warftpd, pureftpd, Bulletproof FTP 
-# Server, and whatever ftp.microsoft.com uses.  Almost all servers use only 
-# ASCII printable characters between the "220" and the "FTP", but non-English
-# ones might use others.
-# 
-# The next thing the server sends is a 331.  All the above servers also 
-# send something including "password" after this code.  By default, we 
-# do not match on this because it takes another packet and is more work 
-# for regexec.
-
-ftp
-# by default, we allow only ASCII
-^220[\x09-\x0d -~]*ftp
-
-# This covers UTF-8 as well 
-#^220[\x09-\x0d -~\x80-\xfd]*ftp
-
-# This allows any characters and is about 4x faster than either of the above 
-# (which are about the same as each other)
-#^220.*ftp
-
-# This is much slower
-#^220[\x09-\x0d -~]*ftp|331[\x09-\x0d -~]*password
-
-# This pattern is more precise, but takes longer to match. (3 packets vs. 1)
-#^220[\x09-\x0d -~]*\x0d\x0aUSER[\x09-\x0d -~]*\x0d\x0a331
-
-# same as above, but slightly less precise and only takes 2 packets.
-#^220[\x09-\x0d -~]*\x0d\x0aUSER[\x09-\x0d -~]*\x0d\x0a
