I get really annoyed when I am in command line or doing a big purge of software and I have to enter my root password every minute or so.
How to change the length my elevated privileges are up?
I believe the thread title says it all: I do not (always) see an icon that allows me to drop elevated privileges before time runs out. I've been trying to find the settings for this for an hour or so, but couldn't find it. Does anyone know where to look?

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'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.

View 4 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?
Ubuntu 10.04
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?
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?
Whenever i mount any disk to ubuntu,and after typing the password, a new icon is created on the taskbar which says "click here to drop all elevated priviledges".
The icon is of harm even i click it or not but i was just curious to know more about it.
regarding user permissions:
I have user A who owns a .jar file
I have user B. who needs to run the .jar file
I have Java which is owned by root.
I would like to work out whether/how user B can run the .jar file, in Java, with the permissions of user A. As I understand it, a running process in Linux typically takes the permissions of the user who executes it. However, the way I'd like to configure user B, the permissions I want them to have wouldn't be sufficient for the process to successfully run.I know you can also set a process to take the permissions of the owner of that process, but in this case the actual... executing process would be Java, which runs the .jar file, and I def. don't need this, let alone every single instance of Java on my server, to execute with root priviledges. So like I said, basically I am trying to work out how to let user B run this specific process with the process elevated to this set of priviledges which user B otherwise does not have.
I recently started running a Minecraft server for myself and some friends and am running it via Linux. I'd like to set things up so that a friend of mine can, as needed, telnet into the server and restart Minecraft as needed, as well as a couple of other things, without giving this friend the same access rights I've given myself to the same files. The minecraft server process runs in a screen, and I've worked out where screen can be set up so multiple users can get into it. However, if I'm running minecraft under my own user name, then that seems like it will just end up letting my friend, from his account, screen into my own account. SO the brilliant idea I had was, what if I had one user account which only existed to run the server, which both me and my friend could screen into as needed, which wouldn't have any more rights to anything than my friend has with the exception of being able to execute this one .jar in Java.
I want a line or lines to check for variable length in my script. I just want to check if a variable the user inputted is 4 characters long, and if it isn't to return a false or exit status of 0.
View 6 Replies View RelatedI need a little insight, and I�m not sure if the two can relate, but I am trying to find out the following.
When generating WEP Keys the available bits are: 64/128/152/256; however, you need 5/13/16/29 character respectfully for each key if you generate the key manually.Can this formula be applied to passwords and the length of the password? For example: if my password had 29 characters, could I say that my password is 256-bits?
Is it possible to prevent the panel from expanding to where the -ox buttons appear on a full sized window. I use the panel hide pref with the panel not fully extended to the width of the scree. If the panel gets too big then it drops down each time I click to close the window. I would like to limit the overall length of a panel. Is it possible?

did a search and I can't believe I seem to be only person reporting this. It's been a bug since I did a fresh install of 10.04 UNR, but it's only gotten to the tipping point where I actually HAVE to do something about it today. I finally cracked.As you can see in the screen shot attached the one line text box (ie, search bars mostly, but the thread title in this case) stretches way beyond length it is supposed to. For the first screen shot I have "zoomed out" to give a better idea of the full effect, the second screen is what I see during normal browsing.If anyone could help me fix this error it would be greatly appreciated. I've tried both Firefox and Chrome (and Chromium) and the same issue occours. The screen shot is taken from Chrome 5.0.375.70

I would like to know how can I find array length in C .I have array of structure and I want to sent it to different functions and I want to have it's length (number of elements) each time I want to use it and I don't like to use any additional variable to pass the function for each of arrays that I pass to function.
How can I do that?
I want to calculate length of my array, say Unix here.
Code:
[linux1@HMLINUX1 abc]$ declare -a Unix=('Debian' 'Red Hat' 'Suse' 'Fedora');
[linux1@HMLINUX1 abc]$
[linux1@HMLINUX1 abc]$ echo ${#Unix[@]}
5
This should be ideally 4, but somehow it is showing as 5. However, when I am removing the space as RedHat instead of Red Hat, it is working perfectly.
Code:
[linux1@HMLINUX1 abc]$ declare -a Unix=('Debian' 'Redhat' 'Suse' 'Fedora');
[linux1@HMLINUX1 abc]$ echo ${#names[@]}

View 5 Replies View RelatedThis is just an idea, and I want to know if it can be done. Could I set up Nautilus so that videos and songs have their durations shown in the filename? For example, let's say I have a video of me shooting targets. There would be an icon, and the filename underneath would say: "Range trip 2009.flv - 8:23"
Is there currently a way to do this?
Some (very few) mp3 files on my hard drive seem to self-report incorrect (much too long) lengths to audio players. I mostly use Amarok, but I've verified that the problem also occurs with other audio players. The files play just fine, but it's annoying that they're listed with incorrect length. Most of my mp3s are encoded using VBR, but I can't imagine that that's a problem ... and if it were, it would be occurring with a lot more files, I'd think.I'm guessing there's a problem with the file header itself on these files. Is there some way I can check this and correct it, if that is the problem? A quick check through Synaptic didn't turn anything useful-looking up, and neither did a search through these forums.

Does anyone know how to increase the mousewheel scroll length? Take for example, Google Chrome, in a Windows operating system one tick in the mouse scroll wheel moves the page 10 lines, while in Linux one tick only moves the page 4-5 lines which can be quite annoying when scrolling through large webpages, does anyone know how to change the scroll length? I'm using Fedora 14 x86_64
