I want to set limit for each user to dl on an ftp. So, if he or she give our his or her user&pass, the limitation will also count. For example, each ftp account has limitation of 50gb to download, he or she dl 20gb already, then he/she will have only 30gb left. This is just like ftp server (Bulletproof), but I don't know how to set it on proftpd.
Would anyone kindly show me how to do like this? Thanks
