I have a RedHat Linux 8 box running vsftpd. I'm experiencing an issue where users login and can descend out of their home directories. I've tried various different ways of creating the user.. different groups, uids, etc.. Any ideas?

Regards,
Bill

By "descend out of their home directories." are you talking about a "joe-user accessing /home/joe-user/sub-dir or a joe-user accessing /home/other-user? you can't keep a user from accessing subdirectories of their FTP "home dir" but you can chroot them into their home dir and prevent them from seeing anything else on the system.

That is exactly what I want to accomplish.

Mmm.. perhaps I'm doing something wrong here.. The only thing I'm getting is:
chroot: cannot execute /bin/bash: No such file or directory

when I try to excute the chroot command?!?!

Are you using "chroot_local_user=YES" in your vsftp config?

Well, I am now and everything is working perfect.

Now I need to discover a way when adding a user explictly for FTP that it automatically writes that username to the vsftpd.chroot_list..

Thanks again!

The only way I know of to do that is to either use a wrapper around useradd/userdel or to set up a cron job that picks users out of /etc/passwd and adds them to the file.
