-# FTP - File Transfer Protocol - RFC 959
-# Pattern quality: great fast
-# Protocol groups: ietf_internet_standard document_retrieval
-#
-# 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.
-#
-# To get or provide more information about this protocol and/or pattern:
-# http://www.protocolinfo.org/wiki/FTP
-# http://lists.sourceforge.net/lists/listinfo/l7-filter-developers
-#
-# Matches the first two things a server should say. 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. Just in case, the next
-# thing the server sends is a 331. All the above servers also send
-# something including "password" after this code.
-ftp
-# actually, let's just do the first for now, it's faster
-^220[\x09-\x0d -~]*ftp
-
-# This is ~10x faster if the stream starts with "220"
-#^220.*ftp
-
-# This will match more, but 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
