im on ubuntu, and i was trying to change the settings under System->preference->network proxy
When i click apply system wide, it asks me for my root password wich i provide and then it asks me for this other password, with this message: Privileges are required to change gconf system values. What is this? is there a way around it?
I've been searching for the answer to my question for quite some time on google, no luck. Due to my searchings I've become very familiar with nice and renice.
I have a script I use for launching a game installed with wine. I cannot/wont run this game as root but I need to be able to use nice --7. As of now I can't I -- ofc -- get "permission denied"..
So how do I make the full range of niceness ( [-19;20] IIRC ) available for all users on my system -- or even just for 1 user?
I have a script that runs lots and lots of root commands, copying files in /usr/...stuff like that, then i want to switch users back to the original user and run some gconf tweaks, I need to update a series of gconf values for a user after copying all the root files, but I noticed once your in root, any gconf values you change, change roots information, not the user who started the script useing sudo.
So i was wondering how you would run a script as root, then after your done with all the root commands, "un-root" to the current user who started the script and run the gconf edits:
I put together this so far. It a script that you run, it detects if it was started as root and if not it asks for root password and re-spawns its self exiting out the first instance, then the script runs, switches to the original user after all files are copyed over and starts to run the Military Time custom format update.
Code:
OUSER="`whoami`"
if [ "$(id -u)" != "0" ]; then
sudo -K
sudo bash $0
[Code]....
I am about to install some software on Red Hat Linux. I can understand all the instructions apart from the first. It says Log on to the UNIX system with the privileges required to install software. You can create an
account specifically for this purpose. Caution: Do not install as root. What does this mean exactly?
I am trying to install openoffice and I get. Note this installation will be done without root privileges. Therefore you will have reduced functionality. Change privileges to root privileges if you want full functionality. I have opened a terminal and su to root with no avail.

View 3 Replies View RelatedSo I have done some googling and experimenting to change the GDM icon (Ubuntu 10.04) and have found the following ways:
UbuntTweak
Replace /usr/share/icons/LoginIcons/apps/64/computer.svg with your own svg
Change the gconf config setting /apps/gdm/simple-greeter/logo_icon_name to be the name of your icon in the theme. Then copy that file to the icon theme path: /usr/share/icons/LoginIcons/apps/64/.
I have gotten #1 and #2 to work. I am not sure how UbuntuTweak is actually doing it's magic (but would love to know). I do not like #2 as it seems messy and what not.
I can not get #3 to work. I have found post after post that says it should. I have tried editing the gconf DB in multiple ways:
gksu gconf-editor
gksu -u gdm gconf-editor
sudo -u gdm gconftool-2 --set --type string /apps/gdm/simple-greeter/logo_icon_name MYICONFILE
sudo gconftool-2 --set --type string /apps/gdm/simple-greeter/logo_icon_name MYICONFILE
And while all of those methods show that the value has been edited NONE of them actually change the icon (did a service gdm restart to check).
Given that:
The official docs state that this should work By replacing the computer.svg file it does work (so I know I am copying my file to the correct path)
I can use the gconf-editor to disable the screen-saver lock and set it to activate when its idle. But no matter what I change /apps/gnome-screensaver/idle_delay to, the ScreenSaver UI is never updated and stays at the default 5 minutes. There seems to be no link between the slider bar in the ScreenSaver Preferences and the value that lies at /apps/gnome-screensaver/idle_delay...
The reason why I'm doing it through gconf-editor is so a start-up script I have created can use gconftool-2 to alter settings for certain users on login.
Is this broken in Ubunto 10.04 or am I looking in the wrong place.
I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

Recently I was going through some chmod manipulations and found the umask values to be 0002 by default in Fedora 11 distro. What I knew about the default values to be 022. I don't know whether this is a kernel modification in this distro or my system is in compromise(I doubt for the latter option, but not confirmed).

How to change the length my elevated privileges are up?
I've been using Ubuntu for like a year now. Whenever I want root privileges I just type sudo and enter my User password. I wanna know if there's a way to change this, in a way that My User password is: "ABC" and the password needed to have root privileges is: "ABC123". I have no problem using the terminal, I actually prefer it to any GUI, it just seems easier to me.

When I execute a sudo or gksu evolution (e.g. synaptic package manager) I find that the escalated privileges remain in effect for a period of time. Sometimes, not often, the notifier applet shows an icon indicating that escalated privileges are in effect.
What I would like to know:
What is the default amount of time which escalated privileges remain in effect on my system?
Is it possible, if so how, to change this amount of time?
If I do System-Preferences-Personal File Sharing it tells me that I can't enable sharing over the network because "the required packages are not installed on your system". It doesn't tell me WHAT packages I need to install!
View 1 Replies View RelatedI have my home network set up like so. My router has 4 ethernet ports so I have 1 hooked up to a network hub where I have 2 computers running windows xp and 1 running windows 95, on my other router port I have a desktop using ubuntu 11.04 and I have 2 windows 7 laptops and 1 ubuntu 11.04 laptop connecting wirelessly. All of the computers can see each other in my network map except for the ones running ubuntu. I can successfully ping every computer on my network from every computer without fail (even the ubuntu ones). The weird thing is that my ubuntu computers can see and use files from all of my windows computers but still nothing can see the ubuntu computers. I have set up samba to no avail and when I open file sharing and try to enable it on ubuntu it comes up with "this feature cannot be enabled because the required packages are not installed on your system." I have done clean installs of ubuntu 11.04 and 10.10 on both ubuntu computers and kept them up to date but the same problem persists. I have tried to do the same steps above with all of my computers wired but still nothing.

View 4 Replies View RelatedMy question is about TCP parameters in Linux. By now, I want to change the default values of:
Initial Timeout
ACK Delay
Idle Connection Timeout
I have a Linux Box with kernel 2.6.x and 2 ethernet interfaces. I know TCP is a stack that doesn't have anything to do with ethernet devices. Said that, the question: is there a way to set custom values for each interface? For example, a server listening to connections in eth0 would use one value for Idle Connection Timeout and another server listening to connections in eth1 could use a different value for that parameter.
I would like to enable personal file sharing so I can access my laptop (hp Mini laptop w/ ubuntu) from my mac mini (OSX 10.4.11), but the message I get in PFS dialogue box is "This feature cannot be enabled because the required packages are not installed on your system".
View 1 Replies View RelatedSince reinstalling Ubuntu 9.10 and learning how to get the Notification Area working properly:
I've noticed an bunch-of-keys icon appearing intermittently in my notification area.
It appeared about 20 mins ago. I hovered the mouse over it and it generated the following text:
"Click on the icon to drop all elevated privileges"
I right-clicked on the icon, thinking I might learn something more about it. But it disappeared. No other messages were given.
It appeared again about five or ten minutes ago. I did not click on it. But it disappeared of its own accord after a minute or two.
What is this? Should I have clicked on it? What have I done? How can I get this bunch of keys under my control?

View 2 Replies View RelatedI've implemented a few custom system calls in my Ubuntu kernel, but I'm having some issues with the return values. Each function returns a variety of non-negative integers depending on which error is encountered. However, when I'm testing the system calls, the only negative value that gets returned to the user program is -1, regardless of what I have in the code.
Is there some special path I have to take to get the proper return values?
I know that some settings can only accessed by root (like the login manager). KDE 3 had a button where you could become root to access it.Where is this button in KDE 4? After googling I found year old articles mentioned that you should kdesu gksu systemstettings in CLI, which was ok when KDE 4 was new, buggy. But my hairs stand on end of having to use such a dirty workaround for a standard feature.Has KDE 4 taken a step back, lost an essetial and obviously necessary feature here compared to 3?

Why rebooting is not required in linux after installing an application even if related important files are running?
View 3 Replies View RelatedAccording to the man page, the "recent" match of iptables accepts certain parameters (e.g. "ip_list_tot"). I'd like to change the values of some of them.
All the solutions found on the web were about changing parameters for module, but my kernel was compiled without modules support (such that it can be used for installation booting as well).
How can I change the match parameters for my non-modular kernel ?
I'm looking for a program that will add cookies to my web browser (firefox or chrome, preferably). The application would ask me for the Cookie's:Name

I want to access suse pc from redhat remotely.
i need a remote access tool so that i could access my branch Suse operating system pc through Internet. i am getting teamviewer for linux, it is installed properly but not executing.
My server is not accessible any longer locally (192.168.0.2). If I attach a keyboard and login (I have done one pass of recovery from the Ubuntu live CD which helped) and check the IP address it seems to be set. However looking at the syslog file there is a line which says ext3-fs: info: recovery required on read only files system.
Is there a more extensive ext3 recovery facility I can use bearing in mind I will not (?) be able to install it?
I think I'm running 8.6 but not sure where to look to find it.
I installed the minimal-command line system from the kubuntu CD on my laptop, which is guess is roughly around 200mb after installation. I wish to install a Desktop Environment preferably KDE and I wanted to know how and where do I begin from? Do I need to have a working XORG prior to installation of KDE and do I also need to install Window mangers and e.t.c? What all packages/libraries and components do I need to install first? I'm really not sure where should I begin from.
Initially what I am trying to do is to have working GUI system,then later on I can install rest of the packages and software that I need, like office, GPU drivers, browser etc. Secondly,for a minimal KDE system,what metapackages are to be installed from this site? I believe kdebase, kdebase-runtime, kdebase-workspace are required. [URL]
