Logon Legal Notice for Fedora 1

[southside]

Hi All,

Can anybody please advise how I can configure a Legal Notice advising against Computer Misuse that will display as soon as a user logs on. I am looking at something that will not complete a log-on if it is not accepted.

There are a few ways... First, there is the file /etc/motd which is diplayed when a console window/telnet/ssh session is started. This means all your terminal windows will probably get them too. If everyone is using SSH to logon to a central server, it's as simple as adding a banner to /etc/sshd_config:

Banner /etc/notice

Our /etc/notice:

Thanks....that info will be useful on some servers.


Is there something that can appear during a graphical login - such as a banner that will need to be acknowledge when a user logs in. We have some servers that are not ssh'd or telnetted to, just local user access but we need the Login Security Banner/discalimer info for the login.

The background for the logon screen can be changed. You could add a message that "logging in to this computer indicates you have read and agree to all the rules of the company (and will but donuts for the IT staff on Friday)

Try
kdialog --title "Company" --msgbox "Blah Blah"


"If you always do what you've always done, you will always be where you've always been."

kdialog --title "Company" --msgbox "Blah Blah"

Requires KDE... If you don't have KDE, you could make it so that a terminal is open on login, and the message displayed...

xterm -hold -e echo "message"

Thanks Guys.......I'll try these out. I am running KDe so that's a big advantage.

This is what I do for the DOD. In your /etc/X11/xdm/Xsetup_0 file add the following line after the /usr/X11R6/bin/xsetroot command

xmessage -center -file /etc/login.banner

I have the government official warning banner in the /etc/login.banner file.

I do not ask for compliance with a yes or no but instead offer an ok button at which point login continues. If you want them to answer yes or no do something like the following on the above line.

xmessage -center -file /etc/login.banner -buttons yes:0, no,1

Then you will have to add some logic after to verify there answer before proceeding with the rest of the login. If this part does not work at first please read the man page on xmessage as I am not in front of a Linux box at the moment. For me, just displaying the message and forcing a user to click ok is enough to ensure non-repudiation as required by the govt.

Also a symlink such as ln -s /etc/login.banner /etc/motd will take care of the telnet, ssh (post authentication) and console users.

Hope this helps
