Jan 4, 2011During set-up of a home server (running Kubuntu 10.04), I created an admin user for performing administrative tasks that may require an unmounted home.

Ubuntu Servers :: Restrict User Session Numbers And Allow Resuming Previous User Session?
Jun 30, 2010I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.
General :: Login As Other User Using Shell Doesn't Load The Profile For That User?
Dec 11, 2009I am using the sudo command to log on locally as another user by the following command:

Fedora Security :: Restrict User To Ssh?
Apr 7, 2011I m new with Fedora 14, and i have a basic business case :
I want to setup a user which should
- only connect to the server with SSH (ex.: no X11 connection).
- cannot change its shell
- cannot do any SU / SUDO command
This user is very similar to a SERVICE user, as I expect him only to run a single program (its shell).

Apr 13, 2011I am running RHEL release 4 (Nahant Update 6). I currently have a fax server that has been encountering issues recently after hours. My boss would like our helpdesk to monitor the status of these modems throughout their shift. This has led to a request for a helpdesk account to be created on our linux box that only has access to a few commands. Is there a way to limit the new user to only have access to the following commands?
cd
less
cat
Additionally I would like to create a script for them to run that would chmod our modems when necessary since their permissions reset after a power cycle. BUT not give them access to the chmod command, just chmod through that script for those specific devices.
Security :: How To Restrict Permission To Ssh User
Jan 26, 2011I would like to allow a user to login through SSH but with different permission coming from different ipaddress.
For example, a user "tester" login to SSH through 192.168.1.1 and another user login with the same login id "tester" but from different ip 192.168.1.2.
How do I restrict 192.168.1.2 to only allow for viewing the content in the home directory while giving 192.168.1.1 full access?
Security :: Restrict User To One Directory Only?
Jan 6, 2010Here's the beginning of the issue: I'm running Fedora 12 with httpd and sshd. I want to create a user with a scponly shell for sftp access, but this user should ONLY be able to view /the/http/base/dir and its subdirectories. The user should not be able to see or get into directories above the httpd base. Someone mentioned creating a chroot jail for sshd and binding the httpd base to that dir, but this seems like more work than is necessary for the application I wish. Also mentioned was creating a user, say user1 with a selinux user setting of staff_r. I have read the articles and creating a user of staff_r isn't overly difficult, but how would I make it where staff_r would be restricted to where I want them to be? If I'm not mistaken, that would require changing the context of /the/httpd/base/dir?

Debian Configuration :: Restrict FTP Access To User's Home Directory Only
Jan 18, 20112 of us have been googling all morning trying to find out how we can restrict ftp logins to their own home directories only but nothing we've found so far has worked. We've tweaked sshd_config so that they default to their home directory but they are able to navigate up/across/down to everything. This is a "straight-out-of-the-box" debian 5.0.5 Netinst. Just a basic system with Apache/MySql/PHP/SSH and no desktop.
