mod_ratio

To install, copy this file into modules/ and do: ./configure --with-modules=mod_ratio This module is inactive unless configured, which can be done with an Anonymous, Directory, or VirtualHost block in proftpd.conf, or with a .ftpaccess file. (Ratios must be turned on elsewhere for a directive in .ftpaccess to take effect.) If compiled with -DMOD_MYSQL_RATIOS, this module can get and set session stats using mod_mysql, so the only directive needed is "Ratios on". This acts like a weak "UserRatio" -- any directive described below can override it. It also makes multiple concurrent uploads/downloads possible, with persistent credits. See mod_mysql docs for setup details. Most ratio directives take four numbers: file ratio, initial file credit, byte ratio, and initial byte credit. Setting either ratio to 0 disables that check: FooRatio bar [frate] [fcred] [brate] [bcred] The directives are HostRatio (matches FQDN -- wildcards are allowed in this one), AnonRatio (matches password entered in an anon login, usually an email address), UserRatio (accepts "*" for 'any user'), and GroupRatio. Matches are looked for in that order. Some examples: Ratios on # enable module UserRatio ftp 0 0 0 0 HostRatio master.debian.org 0 0 0 0 # leech access (default) GroupRatio proftpd 100 10 5 100000 # 100:1 files, 10 file cred 5:1 bytes, 100k byte cred AnonRatio billg@microsoft.com 1 0 1 0 # 1:1 ratio, no credits UserRatio * 5 5 5 50000 # special default case FileRatioErrMsg "Come on you can send more files than that...." ByteRatioErrMsg "This file is %i big, you know...." LeechRatioMsg "Access: Unlimited" Setting "Ratios on" without configuring anything else will enable leech mode: it logs activity and sends status messages to the ftp client, but doesn't restrict traffic. Ratio module activity is recorded to syslog at DEBUG0; it usually shows up in /var/log/debug, like this: foo in /: CWD /teen :-15/3450 +0/0 (my 5 15 5 150000) =0/146550 [NO F] This example is for someone who (1) has downloaded 15 files totalling 3450k, (2) has uploaded nothing, (3) has a ratio of 5:1 files and 15:1 bytes, (4) has 0 files and 146k credit remaining, (5) got the ratio from the MySQL record ("my") and (6) is changing directory from / to /teen. Note that if this module is turned on globally, any user can create a personal ratio area with a .ftpaccess file. One way to prevent this is with: PathDenyFilter "\.ftpaccess$" The authors of this module, this ProFTPD software, and this OS and kernel disclaim all warranties and are not responsible for what random users of this module may do.
