[SOLVED] Restrict Access to Ubuntu GUI

[flygy6]

Hi,

I am running a file server that runs pure-ftpd. It also provides access via rsync tunneled through ssh and sftp. I want to set up users of the file server so that they have access to ssh (in order to use rsync) (I use rssh in chroot jail for a shell) and they also have access to the ftp server, but I want to restrict these users' access to the local system, both through the terminals (tty1 ...) and through the gui. I am using hardy heron ubuntu. I successfully restricted access to the terminals using /etc/security/access.conf, but I cannot restrict access to the gui for any user. Please help.
Thank you,
flygy6

I'm not sure I understand. If you only have one gui installed, how can they access through any other? (or do you have more than one installed?)

Hi

under System-> Administration -> Login Window -> Security you can change various settings related to login and security, maybe these are of help.
(I think these settings are for gui-logins only? anyone?)

Thanx everyone for replying, but I found the solution I was looking for. I setup user-specific login settings in /etc/security/access.conf. However I needed to enable the various programs such as pure-ftpd, sshd, and gdm to use these user-specific login settings. To do this I needed to go into /etc/pam.d to append the following line:
account required pam_access.so
to every program that I wanted to use access.conf.
I found the solution at:

Thanx again everyone for your help,

If you don't want users to use the gui on your server get, get rid of it. There are no server specific application on the desk top. I would suggest installing webmin to administer your server. Webmin is a web based administration suite. Have a look at Webmin here:

and there is a howto here:
