this should do the trick , the user has full rights to do everything within his own homedirectory

useradd -d /var/www/jsmith -m -p password jsmith



type this to see all possible options for useradd:

man useradd

Also note that you have to have the username at the end, so don't put it at the beginning.

Also, you may or may not want to use -m, it creates the user's home directory if it doesn't exist and it populates it with the files from /etc/skel. Usually you want this to happen though.

 

by: chingmdPosted on 2007-11-05 at 15:13:27ID: 20220368

The only other addition is the possibility of -g <default group>  and -G <group memberships>  Depending on how you have/want the /var/www/html dir configured.

Another method for configuration is to use the pubic_html directory on the machine.  This will allow them to have a home dir, and then an html dir.  

You may want to prevent shell level access, for that add -s /sbin/nologin

broeckske:, thanks but it doesn't quite work. It does create the user, but the user cannot ftp in to their account.

 

by: smetterdPosted on 2007-11-06 at 05:33:38ID: 20223626

The permissions are not correct. Temporarily, I opened it wide up and the ftp works. How can I lock it down? For testing purposes I did a chmod -R 777 ./username/

That made it work but, of course, is not secure.

 

by: chingmdPosted on 2007-11-06 at 09:09:29ID: 20225534

Take a look at /etc/xinetd.conf.   FInd out what user and group the ftp daemon is running as.

You will likely want to do a chmod -R 770 on the directory.  and a chown -R username.FTPGROUP directory.  Essentailly, you need to grant both the FTP process and the user access to the directory.

using username and ftpgroup, will protect the directoies from other users, and stillg rant access to the ftp daemon.

 

by: bayesianmindPosted on 2007-11-06 at 10:50:22ID: 20226406

The other thing you'll want to check are the permissions in the /etc/xinetd.conf file. You can actually grant and revoke additional permissions here. This file's permissions are applied first, then the actual filesystem permissions will take effect. You'll want the user's home directory to be locked down so non FTP users can't mess with it.
