How can I install a minimal GUI interface, on a Ubuntu server? And more: Suse has a RUNLEVEL tool, to select application to be launched. What in Ubuntu? I need a GUI interface ONLY to use some useful administration tools, no other application, and need to charge the system as less as possible.

Most of my gnome system administration tools are (suddenly) failing to open. The system is a new installation with both KDE and gnome, and the gnome system admin tools were working fine, but now they fail silently (nothing even in .xsession-errors). For instance, if I select Synaptic Package manager from the menu, I will get the gksu prompt to enter my administrative password, which I do. Then a notification will appear in the Taskbar "Granting Rights" and then after that nothing happens, it just fails silently. Note that this also happens if I enter 'gksu synaptic' or 'gksu /usr/sbin/synaptic' at the alt-F2 command line. Note that it doesn't seem to matter whether I check "Save Password for Session" or not. The same happens for time-admin, users-admin, etc. I have tried reinstalling gnome-system-tools, system-tools-backends, and gnome-keyring with no effect. I have googled extensively and have found a few other people with this same problem, but no solutions. Note also that kdesu does still work fine, and there doesn't seem to be any such problems in KDE in general. Only in gnome and with gksu.
P.S. Let me know if you need any more info (output from commands, files, etc).

I'm looking for a Syncronizacion Softwares (running as a daemon) to do a unidirectional syncronization of some files/folders from a lot of servers to one central server.As there are a lot of servers i want a software that only needs to be installed on the central server and pulls the files/folders from the other servers.rsync and unison need to be installed on both machines and syncronize the files/folder by sending them from al the servers to the central server(its no the central server the one who pulls the files/folder from the other servers), so they dont work for what i want.

I am replacing a home network - Windows Server 2003 and 5 PCs (XP Pro) with UBUNTU 10.4 LTS Server and client versions. I am keeping a couple of the PCs with dual boot until I can migrate everything over (Having some issues with iTunes, Family Tree Maker, Media serving, DVD decrypt and a couple of others, but that is for another post). It was great fun getting the server up and running using only shell commands. Took me ages just to get a folder shared! Migrating the data over from NTFS to ext3 was also fun given the limited space on the partitions.
I really only want to use the server for communal network type things ... central user account maintenance, shared folders for music, video etc and data backup. I don't need it to be performing server functions on the Internet e.g. web server etc although that may come later. How I set up central user management? All the PCs are currently setup with local user ids, and it is a bit of a pain to go round each PC every time I change something.
The server is not always up, so I need to be able to log into the local PC without it being active. I was using Active Directory on Server 2003, but I don't need anything that complex really ... just 3 or 4 users to manage. I have been looking at the setup tutorial at [URL] but am not sure how relevant a lot of it is. I have SSH setup so I can login remotely, NFS is working to share the folders, but that is about all I have done so far.

I've setup Kerberos and OpenLDAP servers (9.10) similar to the official documentation (and other sites that fill in the "gaps"). However, when you start to get in to some of the details, there seem to be many options - and I guess I'm looking for what could be the defacto standard. I'd like to allow Ubuntu clients to have a sso capability, with the ability for local caching of passwords if not connected to the network (such as a laptop user away from the office, prior to a VPN). I'd like to automount a secure NFS share somewhere in the /home directory. If the user logs in to a computer they've not logged in to before (if they're authorized), it would be nice if a skeleton /home directory could be setup there automatically I'm guessing that it is not desirable to use a shared /home NFS - as if you're off the network this would be problematic - as well as multiple computers sharing the same /home. There are some benefits to a shared /home (SSH certs, etc.), so maybe there is a hybrid approach out there.
I've read that it's not necessarily good practice to have OpenLDAP to do the authentication (leave this to Kerberos), but it's fine for authorization (such as ACLs for logins to certain computers). It's also good practice to use TLS with OpenLDAP (which requires public certs on all the clients) and to not allow anonymous read to the directory. I would guess that a computer host keytab could be refreshed to bind to the OpenLDAP server via GSSAPI / SASL to allow a non-anonymous read, and then determine if, say, the user was a member of a group allowed to log in. Kerberos would then pick up and authenticate the user and then proceed to the login. Off the network here, I'm not sure. I found this document, but it's self declared missing items: [URL]
I'll stop the rambling, but I cannot be the only one who would like to setup a relatively standard and secure server based network authentication and authorization back-end. Is there any _complete_ documentation on the best practices and how to implement?

if I choose Administration --> Printing and then try to select a printer from the list of available printers (to delete a printer for example), the dialog
freezes and needs to be terminated forcibly. It seems like I can hit "New Printer" and add a printer without anything freezing. All of the printers on the list are
network printers.
Possibly related- if I use evince to view and document and then attempt to print by going File --> Print, it gives me a printer selection box which also freezes if I try to choose a printer from the list.

Is there any good LDAP-Administration tool ?
I need to setup test accounts and groups.
For that I can test a LDAP-to-DataBase synchronization tool.
Anything with which I can quickly add users /Groups in the directory structure.
I don't care which LDAP-server, as long as it is stable enough to run for 10 minutes.

I want to make a FTP server with web frontend for administering it, eg creating users, groups, setting which directories users can access and so on.I found some web frontends for proFTPd, like those URL... , bus all of them seems to be very old and doesn't work nicely. I tried ProFTP Administrator and it won't work.Do you know some solutions to manage ftp server users, groups, permissions over web? Or by some frontend program.

simple installs of CentOS5.2 i386 on 2x Dell C640's and x86-64 on a Dell dimension 9150 resulted in the System/Administration menu offering two entries each with the name 'hardware' and the icon showing a little chip hovering over a PC. I did "add this launcher to panel" on both as an easy way of checking their properties:
The higher entry issues the command 'hwbrowser'
The lower entry issues the command 'hal-device-manager'
Both have the comment "view information on the hardware on this computer". I feel the hal-device-manager entry has the wrong name, comment, and icon. I think /etc/xdg/menus/system-settings.menu is relevant.

I am a php devloper and recently my company purchased an IBM X3400 M2 Server and i was told to set up the server.I installed the Ubuntu 10.04 LTS Server i386 version. Everything went up smoothly and i have some queries to be asked.
1.)Our scenario is like this,--> we have an a production LAMP Server and we need the to backup all the contents of www folder and all Mysql files.I plan to do this with a shell script and use the rsync for syncing and backup.
Again i have a mysql backup shell script that i want to activate on system shut down Like when i shut down my server,the backup script should run taking all the backups, just before the Shutdown.The script should run take the backups, one, on the server itself and other on a remote machine sync with rsync and system should then go for Final shut down.How can we achieve this.I know of cron jobs but i prefer the above way.Suggestion requested here.
2.)To Set up a Special Samba share. I need to set up a samba share that will allow only files to be copied and not be deleted.For eg i will create a folder "WEBSITE-BACKUPS"(will contain the list of all finished website works plus mysql dump)
The user on the network will have only permission to paste into this folder.Like a user just paste his work say 'abcwebsite',he will have only this privilege and no DELETE privilege or right.Can this be done?
3.)I have a LAN, in this the IBM Machine is acting as Production LAMP server with around 20 machines connecting and working with files on this server.All other machines are Windows.Can i get a log based on the ip like who has accessed with files at what times or last modification time from an IP address. I usually get complaints from my fellow developers that somebody has deleted or modified their work which is in this IBM Server.So is there any way to monitor this.I also know about subversion,the versioning system but most people here are uncomfortable with check in / check out commands.

Is it possible to install some administrative tools under the System -> Administration tab of the Desktop edition of Ubuntu, so that xinetd, chkconfig, netservices, etc can be controlled? I am left with an uneasy feeling about my Desktop version, and finding that it is running services that I really do not want to allow. Apache2 is running for example, but I really am not a web server (yet). Another service is strigi, the indexer. I prefer to have it turned off at times.What administrative tools does Ubuntu offer that can be placed in the sys-admin tab?

The official repo is not working as per the instructions found here:URL...There is no package called srvadmin-all or srvadmin* or similar or anything omsa or openmanage related.There is hardly anything in the repo so installing the repo doesn't help to yum install anything useful so far.How are you installing Dell OpenManage tools on CentOS 5? Where do you get your rpms from or which repos are you using for that?
