Linux Login Scripts for Client access to Network servers
This page is out of dateplease see http://www.rainsbrook.co.uk/wiki/doku.php?id=rb:linuxloginscripts.
BackgroundThis is a development of the original Novell login script, (see here for original scripts) but now allows logins to cifs, linux/unix over ssh and novell servers. NFS is not supported but may be added later.
DetailsThere are two scripts, login.sh and logout.sh with an associated config file, login.cfg. These scripts are designed to be located on the client system at present, maybe in future the config script could be located on a netlogin share or http server and fetched with wget.
Some icon samples are included, these need to be copied to the systems icon repository. This will require root access for install, but currently there are some permissions which need to be changed on mount.cifs which require root access anyway.
Currently, these are shell commands, not GUI ones with the exception of the password.sh script. This uses Zenity to give gui logins. The password changing script has not been extensively tested and is probably broken. It was written somewhat as a test for zenity.
A desktop icon is generated for each sucessful login, this shows the icon listed below and allows a user to open up the mount point in a gui file manager such as Konqueror or Dolphin. Shell access is of course available.
As these are still development, they can be run with a debug option which provides a verbose dialog of what is being done.
There are no alternative icons for Gnome users or other KDE themes. This should be addressed but is not a high priority.
TestingThe current development work is being done on Fedora 12 using KDE4 and GNOME with some testing on Fedora 8 for KDE3 compatability.
Some work is being done to support Mac OS X, this is not a priority. In principle I'd like this to work on as many *NIX based systems as possible.
ProblemsThe windows login part is handled by mount.cifs (used to be the smbfs command which is now superceeded by cifs). On Fedora 12, samba's mount.cifs has been broken by design to stop it running suid. This stops users from running login scripts, but works as root.
Fix suggested at:- http://fedoraforum.org/forum/showthread.php?p=1325076
This page is also helpful:- http://smb4k.berlios.de/handbook/trouble_shooting_mounting_unmounting.html which suggests downgrading the samba client utilities. This worked for me, but may go wrong again after any updates.
yum downgrade samba-winbind-clients samba-common samba-client libsmbclientAfter downgrading, you will need to set the setuid bit to allow a user to run mount.cifs as root:-
[root@thinkcentre1 ~]# chmod +s `which mount.cifs` [root@thinkcentre1 ~]# chmod +s `which umount.cifs`
Current StatusDue to a change in job, work has slowed on this project due to being forced to use win7 to admin Linux. What a crazy way to do things, I used to suspect vistula and w7 were shit, after having to use w7, I now know it is *really* shit.
Next step will be to try and add LDAP access rather than use local accounts, OpenLDAP will be the first target since I have it running, but it would be nice to try with MAD and maybe Novell's NDS.
