How can I grant an already created user shell access?

redhat19 · 08-14-2013, 11:04 AM

Hi Guys,
Our server runs CentOS 6 here. I had created a user with the following command:

Code:

[root@myserver1 ~]# useradd -c "myApp FTP User" -s /bin/false -d /var/www/vhosts/myapp/httpdocs ftp.myapp

Now, it turns out that the (FTP) user I had created, ftp.myapp now requires shell access.
I have attempted to grant the user shell access by editing the sshd_config file (which is located here /etc/ssh/sshd_config)
I added these line to the file:
AllowUsers myApp
But when I try to login as this user via SSH (I use putty), after inserting the username and password on the command prompt, the screen exits.
What am I missing here?
I would appreciate any useful input/suggestions.
Thanks.

You don't have to edit anything with SSH, but the user you created above has the problem on the line you posted. Read the man page on useradd, and pay particular attention to the "-s" flag. You've specified the users shell to be /bin/false (i.e. NO login shell). So, modify the user with the usermod command, as "usermod -s /bin/bash <username>".

It turns out that I need to grant this user root privileges or sudo rights for some of the admin work the user wants to carry out.
How can I achieve this?

Thanks.

You add the user into the sudoers file, or give them the root password. There are many tutorials you can find on how to configure sudo/sudoers.
