Virtual Services Howto: Virtual FTP 7. Virtual FTP 7.1 InetdWu-ftpd comes with built in support to make it virtual. However, you cannot maintain separate password files for each domain. For example, if [e-mail] and [e-mail] both want an account you would have to make one of them bob2 or have one of the users choose a different user name. Since you now have a virtual filesystem for each domain you have separate password files and this problem goes away. Just create a virtnewuser script and a virtpasswd script in the way mentioned above and you are all set.The inetd.conf entries for wu-ftpd: ftp stream tcp nowait root /usr/local/bin/virtuald \ virtuald /virtual/conf.ftp wu.ftpd -l -a7.2 Anonymous FTPThese are unaffected by the virtuald setup. For an anonymous user just create the FTP user in /virtual/domain1.com/etc/passwd like you would normally. ftp:x:14:50:Anonymous FTP:/var/ftp:/bin/falseThen setup the anonymous FTP directory. You have separate password files for each domain so you can restrict which domain has an anonymous FTP account. Please note that since the FTP server is already chrooted into the /virtual/domain1.com directory you do not have to prefix any paths with it.7.3 Virtual FTP UsersWu-ftpd supports something called a guest group. This allows you to create different FTP areas for each user. The FTP server does a chroot to the specified area so the user cannot go outside that directory tree. If you create the users within a virtual domain this way they will not be able to view the system files.Add the guest's group to the /virtual/domain1.com/etc/ftpaccess file.Create an entry in /virtual/domain1.com/etc/passwd with the chroot dir and the starting home directory separated by /./ : guest1:x:8500:51:Guest FTP:/home/g/guest1/./incoming:/bin/falseThen setup guest's home like you would for anonymous FTP. You have separate password files for each domain so you can specifiy which domains have guest accounts and which users within a domain are guest users. Please note that since the FTP server is already chrooted into the /virtual/domain1.com directory you do not have to prefix any paths with it. o
