glFTPd is a freely available FTPserver which runs on Unix, Linux, and BSD operating systems. It has number of features, like logins restricted by a particular set of IP addresses, transfer quotas per-user and per-group basis, and user/groups not stored in the system files, which make it attractive to private warez servers, including topsites.[1][2][3][4][5] It does have legitimate uses though—a number of web development books recommend it amongst other general purpose FTP servers,[6][7] and some Linux certification exams of SAIR required knowledge of it.[8] It can integrate with Eggdrop through IRC channels.[9]
