Hi all,

I've just been handled the responsibility for a FTP-site. Having no experiens of UNIX at all. And now one of my users needs to have full access to the usr directory and all it's subdirectories, don't know why just trying to do what the boss tells me. The type of UNIX is FreeBSD and the filesystem's ufs. I've been told that with this setup rights can only be given to files and not directories. You can put a user in a group and give access to the file. But a file can only belong to one group. If I've understood this correctly it means that the options are 1. let the user log in as root 2. let him be an ordinary user. Option number 1 is not the one I want to go with.
But then the problem might be solved with ACL's? How can I see what ACL's I've got (if any)? How do I use them?

Thanking you

NAME
ftpusers - list of users that may not log in via the FTP daemon DESCRIPTION
The text file ftpusers contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon. This file is used not merely for system administration purposes but for improving security within a TCP/IP networked environment. It will typically contain a list of the users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP server daemon. Such users usually include root, daemon, bin, uucp, and news. If your FTP server daemon doesn't use ftpusers then it is suggested that you read its documentation to find out how to block access for certain users. Washington University FTP server Daemon (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers. Format The format of ftpusers is very simple. There is one account name (or username) per line. Lines starting with a # are ignored. FILES
/etc/ftpusers SEE ALSO
passwd(5), proftpd(8), wuftpd(8) COLOPHON
