As a root I have added a new user via useradd method and set a password. The problem now when I logged remotely via putty using the new user credential I am able to browse the root folders etc. So how to limit the user just to limited folders only such home folder and maybe one or two other folders.
View 2 RepliesI have a user account which is required to run as part of the operating system and as a service. I am currently attempting to install my companies software on an Ubuntu desktop via wine just for the purpose of finding out if it's do-able.
Is there a way, in Ubuntu, for a user account to be given the local rights assignment to act as part of the operating system and to function as a service in the background?
I feel little silly asking this, I accidently removed from my gnome panel my internet connection, volume control and battery indicator on F11. how can I add this back. It does not show up in the add to panel menu and the applications do not give you back the default feel.

I have a problem with the permission of the directories under /proc, they are readable and accessible only by Owner (they have permission 500 instead of the usual 555) As a consequence, the processes are visible only to the Owners or to Root. For exampleif I want to check if there is mysql
I see it only with the user mysql or with root because the directory has permission 500
This problem obstacles the functioning of some applications that should check the existence of some processes managed by other users. At the beginning all was working well. But after a while the problem appeared and I dont know which is the reason of it. how to restore the standard management of permissions of / proc?]
I have a Ubuntu server Maverick 10:10.

I have already installed Samba and created a local user on the server for myself.
I am at the point where I need to create the share to / and give my user read/write to it.
Additionally if possible I would like for it to be a hidden share for additional security.
How do I control which users are seen from the login screen?

In the past I have used Slackware, but I changed to Gentoo because Slackware don't have a nice package manager. I like Gentoo very much, because you have control over your installation from the very beginning. You can tweak your installation, before it's a running installation.
The main problem is that you need to compile everything from source (this has some benefits), but i haven a 3.0ghz pentium 4, so compiling a full system takes days. That's not I want.
Because of that I tried Debian, it's nice because of the large collection of precompiled packages. However, it's seems like it is less Stable then Gentoo (i run debian sid, because i need the newer applications). It's also harder to configure to my needs.
Is there a (Gentoo-based) distribution that gives the user a lot of control on the installation proces (like gentoo) and afterwards gentoo-like configuration (it was so much better then Debian, for example: Where is the xorgconfig utility in debian? I know there is something called dpkg-reconfigure to configure X, but that didn't asked me about videocard and monitor settings, only keyboard related options)
But the distribution must have binaries for all (or at least a lot of) programs.
Is there such a distribution? What does come closest to my needs?
I'm using squid for proxy server in FC6. I'm also using squidGuard for web-site access restriction. I want to do some exception now for website access.

I have a shared folder that has it's access restricted to certain users on a file server at work. Currently when I try to add a user I follow this process:
Right click the Folder, go to Properties
Click the "Access Control List" tab
Select a user from the "Participants List"
Click Add
For most users this process works fine but with one of them I get the following error:
"Could not add ACL entry: Invalid Argument"
I also tried a script that a former employee created which seems to employ this command:
setfacl -m u:<USER>:rw- <PATH>
Running the command with the correct user and path returns a similar "Invalid Argument" error.

For the past few days I was putting effort on understanding the software control flow starting from "Boot loader" to "Linux User space".
I am consolidating the entire process and putting forth in this forum...It would be great if someone can validate this..It might be useful to other new bees too.
Step 1 : Power up the board
Step 2 : The CPU control goes to EEPROM/storage memory where BIOS resides
Step 3: BIOS gets loaded in RAM and gets executed
Step 4: During execution, the selection of Boot device has to be done with the help of BIOS Menu [Blue screen appearance during start up in normal PC's]
Step 5: BIOS shall access the Bootloader stored in boot device [for eg.,Hard disk]. Boot loader is stored in MBR area.
for explanation purpose I take the following configurations
Bootloader = GRUB
Boot Device = Hard Disk
Step 6: GRUB shall be loaded in RAM and gets executed
Step 7: GRUB shall load the KERNEL image to RAM. Kernel image is stored in Hard Disk.
The question of "How the GRUB knows where the Kernel image is stored".
The answer is
1. In the "Grub.config" file, the location of "Kernel Image" and " Ramdisk Image" [which will be discussed later in the section] is being given.
Step 8: Kernel Image followed by Ramdisk Image is loaded in RAM by GRUB bootloader
Step 9: Kernel Image gets executed...During execution, top portion of the code shall make initial hardware initialization and latter part
of the code shall just decompress the Kernel Image
Step 10 : After decompressing the Kernel Image, it shall decompress
the already loaded Ramdisk Image
Ram disk is just creating a temporary hard disk in RAM. The main responsibility includes it consists of minimal driver files, executables, directory structures to created a TEMPORARY ROOT FILE SYSTEM.
This Temporary Root File system shall be used by Kernel Image
1. Execute the executables to access the Hard disk
2. For creating Permanent Root File System in HARD DISK
Step 11 : Kernel Shall look for the file /Linuxrc in Ramdisk. Linuxrc
is a USER script file [not sure]
Step 12: At the end of script file Linuxrc, the Ramdisk shall give the
control to "USER SPACE" [path for writing the script not known]in Linux kernel
Step 13: USER SPACE is the normal shell

View 1 Replies View RelatedI have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).
Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands
The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?
Volume up, volume down and mute keys on the keyboard don't control the volume any longer.They worked before. Hitting the keys brings up a progress bar widget with the volume level unchangeable, set at 0% (which is not accurate at all).It looks like the key mappings or key bindings are working, but there is a disconnect with actual functionality. The volume cannot be changed or muted anymore from the keyboard.
This worked just fine in KDE on Fedora 11 before upgrading KDE components yesterday with Yumex. I am now using KDE 4.3.2 I don't think that it's a coincidence that it stopped working after doing an update.
I updated the kernel and nVidia drivers too, but this problem exists when I went back and tested with the previous kernel, so I don't suspect the kernel upgrade. No info in Xorg.conf about the keyboard. Is there a setting that I am missing?
Sound works just fine. I can listen to whatever source I like. This is not a problem with the sound drivers as far as I can tell.I just want to be able to control the volume with the keys on my Logitech Illuminated Keyboard, model Y-UY95.

Laptop information: HP Pavilion dv2500t
Code:
Laptop is Dell Latitude C600/C500 with Pentium III 850Mhz, 256Kb L2 Cache, 256MB RAM, ATI M3 video card, HD 20005 MB and sound card is EES Maestro 3i. After trying to do something with Windows 2000 which was installed on the machine, I decided to put Linux without keeping windows on the machine. First I try with Xubuntu (latest version) which was working but slowly, then I found that Debian could work fine on that machine. I have installed latest version 5.08 and was surprised how goodly old machine can work. I solved problems with screen resolution (change from 800x600 to 1024x768) but I couldn't find solution how to fix problem with sound.
Actually I don't have sound on the machine. I looked for a linux driver for that sound card and Dell is only providing windows drivers. Then I found that I can solve the problem with ALSA drivers but I couldn't find the easy way (or any way at all) to install drivers and to get back the sound. When I click on 'Volume Control' (top right corner of the screen) I get the message: 'Volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plugins installed, or that you don't have a sound card configured.'
I have a few multi-user servers in an academic laboratory. I am having a problem with some users maxing out the available RAM, causing such sever slowdowns the machine essentially crashes. My servers are Dell Power Edge's running Ubuntu 8.10 Server Edition (Not my choice). I would like to set a maximum limit on the amount of ram a user can utilize. This morning I experimented with setting limits via /etc/security/limits.conf and using ulimit. Neither of them prevented my test program, a simple infinite loop of mallocs, from crashing the server.

View 3 Replies View RelatedI have had my thinkpad for just a few short months and, it must be that we are heading into summer, but I am starting to finally run into some overheating issues especially when compiling software for awhile, i.e. kernel.
My question would be, "Is it best to let the built in thermal management take care of the issue, and I just need to know what to tweak, or to put on a script solution such as the tp-fancontrol script?
The computer takes about 5-10 minutes to overheat and the message I get in /var/log/messages is "logger: ACPI group thermal_zone / action THM1 is not defined" then it shuts down.
So, any pointers in the right direction would be appreciated.
I am running slackware-current x86_64 on a Lenovo Thinkpad T500.
After running my computer for a while, my volume control always messes up. I wonder if it is some app. Mute, raise, lower volume all fail, and so does the little volume icon in my notification area. When the computer boots up things are fine. I can do some more testing later to try and pinpoint the source but I need to wait a few hours for a download to finish. I can still use Advanced Volume Control and all the options there work.

It's not particularly important whether or not she could view the local

What is important is performance of screen updates - her connection
(although broadband) can be a bit slow at times.
Can anyone recommend a straightforward and reliable method to do this? I
am quite happy digging through documentation.
I have Googled, and there seem to be many alternative approaches.
Is VNC the way to go (and if so, which one)? Or something else?
