Classnotes | UNIX03 | RecentChanges | Preferences For our example, we will be using a user called "Mort". Mort will be the user who will have a chroot'ed guest account for FTP purposes.
Create Mort's entry in /etc/passwd and /etc/group. Do so manually, or use adduser or whatever your Unix supports. If you use adduser, you will probably have to make manual modifications to get the /./ information in the home path.
What is this /./ thing? That's the general way to enable chroot'ed accounts on a system. We have not seen this before because everything we have chroot'ed has performed this step automatically.
The /./ sequence determines where the chroot() is done to. If you want the chroot() done to the web directory and a chdir() to mort, it would look like this:
The current releases of wu-ftpd come with /etc/ftpaccess enabled by default. If your version does not do this for some reason, you must do one of two thing to properly use /etc/ftpaccess:
compile the source to use /etc/ftpaccess by default; modify the source to set
use_accessfile = 1;
or run the daemon with the -a option.
/etc/ftpaccess:
class local real,guest,anonymous ......
... ^^^^^
define 'guest' in the proper classes. This is site dependent.
delete no anonymous,guest # delete permission?
overwrite no anonymous,guest # overwrite permission?
rename no anonymous,guest # rename permission?
chmod no anonymous,guest # chmod permission?
umask no anonymous,guest # umask permission?
... ^^^^^
decide if guest should be in this permission list. This is site dependent.
