# FTP - File Transfer Protocol - RFC 959
|
|
# Pattern quality: great fast
|
|
#
|
|
# 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. If it does not
|
|
# work for you, or you believe it could be improved, please post to
|
|
# l7-filter-developers@lists.sf.net . This list may be subscribed to at

|
# 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
