View 2 Replies View RelatedI have to add my students as a user to a class-server to have them work on some TCP/IP-related questions. The server is Debian Lenny.
It would be easy if I could make some kind of script to add them, even with a standard password like 'abc123'. I want to show them the way FTP uses clear-text passwords as opposed to SFTP. Or the differences between telnet and ssh.
I know something about scripting with bash, but how can I add the same standard password to each user, without having to type it for everyone?
Is it possible to switch users in Debian without entering a password, as in Ubuntu Maverick? I already tried adding a nopasswdlogin group but it did not work, even though the "don't ask for password on login" entry in the login manager is no longer greyed out. Replacing gdm3 with gdm also did not work.
View 5 Replies View Relateddue to an exercise in Operating Systems I have to do the following: There are 6 users, user1, user2 ... user6 with home directories /users/user1 ... users/user6. User1 to user3 belong to group1, user4 to user6 belong to group2. The System Administrator wants to change the privilege* only to users 1, 2 and 3 to execute the file /bin/xxx.

Anyway, there is just one big problem (or I miss a simple tip to do it )
We have 1300 students. If I must create them one by one, that will take a lot of time. Actually with the apple server, we can go on a web interface & import an excel list with theses columns :
"Name", "Login", "Password", "Class", "Group", "HDD Space", "Print quota", "Internet access or not", etc ...
Due to this tool, I can upload an excel files with my 1300 students & a couple hours after, they have an account with a personal space & a shared space with their class.
My question is : This tool exist on Debian/Linux world ?

View 1 Replies View RelatedI need to be able to capture a users password when they login. I am well aware of the security issues with this and I'm ok with this.
We run a call center and I am working on migrating from windows to Kubuntu for the callers. It's policy that all callers must report their password to me, so I already know of everyone's password. There has to be some variable/script that I can "hack" to get the password they typed in to the login screen.
What I'm trying to do is that when a user logs in in for the first time, their profile is automatically created and set up. Setting up network drives, email, pidgin (which the password is stored in plain text anyway, so forget about security on that one), web apps, etc.
Trying to find information on How to capture a users password and all have been responded with the usual lecture on why you shouldn't do this. So I've heard it all before and I know of the risks. Like I said, I already have the callers password on file. If I could capture it, I wouldn't have to manually setup each profile every time we get a new caller, which is often since turnover is quite high in call centers.

View 2 Replies View RelatedI'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious.I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users.Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways?(I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password.
