General :: Advanced Uses Of Kickstart - Write A Report With A Full And Detailed Analysis Of The Two Methods
Apr 30, 2010
Does anyone know or have a book on the advanced uses of kickstart and its deployment methods? I have a challenge and its to: Write a report with a full and detailed analysis of the two methods,(remote installation methods of linux and windows) their differences, and a comparison of features and performance.
I am also going to have two servers (one Windows one Linux)thay deploy a virtual network of VMs with different scopes and policies. What can i really do to go beyond the scopes and policies?
I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info /home/user1 disk usage /home/user2 directory info /home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
I remotely access to my OPENsuse 11. I am using TightVNC program. There is nothing wrong with accessing. But I have to start an analysis program, an this analysis takes about 4 to 6 hours. Therefore, I want to disconnect and let my analysis continue.But after disconnecting from suse, the program i started stops to work. Does anybody know how not to kill the program while i am not connected?
I have a file server running 10.04. I have a user that belongs to 2 groups (users is the primary and IT is the secondary). I have permissions set up so that this user and other users that belong to the IT groups can read/write files and others have no permissions whatsoever. I have also set the umask to 0007 so that any files created have the effective permissions. My concern is this: since my primary group is users, is it possible for me to create files with the owner group IT for only this specific folder?
I work with python and I use emacs as my IDE tool. I have been running Debian Squeeze (6.0.9) for some time now with emacs 23.2.1 and ecb 2.32. I am able to access my python methods in the ecb-methods window with no problems. However I recently upgraded my desktop to Debian Wheezy (7.5) running emacs 23.4.1 and ecb 2.40 but I have lost access to the methods in the ecb-methods window. The window is just empty while the others (directories, sources and history) are all populated. I have a second laptop which I decided to upgrade to Debian Jessie, however Jessie recommends emacs 23.4.1 which is running with ecb 2.40 also. The result is the same as on Wheezy.
I have used the ecb menus and googled for a solution or even just a mention that such a problem exists but have come up with nothing. Either I have a unique situation here or am doing something really dumb.
I would like to upgrade to Wheezy or Jessie but I need access to methods in the ecb methods window. How to keep my upgrade and see the methods in the methods window of the ecb system ....
I'm trying to create a user account for my children in Ubuntu 10.04
When creating their account, I have turned off the 'Connect to ethernet and wireless' option of the Advanced Settings.
However, when I log into their accounts, they still have full access to the internet through both the wireless and ethernet connections. Is this option for some other purpose?
Is there an alternate way to limit internet access for childrens' accounts in Ubuntu? (I'm used to MS Family Safety as a filter for internet access - is there an eqivalent for Ubuntu?)
I have a working build of crosstool - it was built for gcc 3.4.3 using glibc 2.3.5 going from 32-bit x86 linux to 64-bit alpha linux. As far as I can tell -- it compiles correctly (output of alpha emulation matches expected) but it has a major flaw. When I use the cross compiler and attempt to add detailed debug information, it compiles, but does not have the debug information. For example, when I execute:
/home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump: hello: no recognized debugging information
Frustratingly - if I use my x86 gcc version 3.4.6 to do the compilation (same arguments, just using the x86 compiler, not the cross compiler) - it correctly embeds the debug information.
In fact I'm not the systems administrator, but I have a strange problem unzipping a file. I think is a problem of memory or swap space or somethin similar, but I'm going explain the problem in detail: Distribution: Red Hat Enterprise Linux ES release 4 (Nahant Update 3) I'm connected as root. I have this zipped file: -rw-r--r-- 1 root root 678183271 abr 7 15:30 Master032010.zip it contains a 2,4G file
i am looking for a detailed description of the login process for both root and normal user , also locally and remotely.i read some sentences that the files .bashrc and bash_profile are needed for this process. But that was very concise.
I have 4 machines; all multiboot. I want each machine to have full rw access to file shares on each other machine, AND, full rw access to the other partitions on the same machine home folder for UNbooted OS's. I imagine Samba will NOT handle all these configurations? What else do I have to do, so that, for example, if I have 2 machines on, and I boot up a third machine in another room, it will auto mount the other 2 machines' shares, and it export it's own shares to the other 2 machines? I want also each machine to have full rw access to shares on the UNbooted partitions of each machine.
What are the possible problem when Windows access the file from Ubuntu got Read Only even though have a full permission to read, write and execute the file? Ubuntu to Ubuntu accessing the file there is no problem only Windows got a problem.
I am making comparison between tora , dsr , dsdv and aodv. There is some error in tora.tcl protocol. Rest is working fine..why the tora.tcl is popping the error?
Error is given below:- Code: num_nodes is set 6 INITIALIZE THE LIST xListHead (_o22 cmd line 1) invoked from within "_o22 cmd port-dmux _o37" invoked from within "catch "$self cmd $args" ret" invoked from within "if [catch "$self cmd $args" ret] { set cls [$self info class] global errorInfo set savedInfo $errorInfo error "error when calling class $cls: $args" $..." .....
recommend some really good performance analysis tools? Top is not good because it has problems.I am looking for some products like collectD, collectl, or something else comparable.I need something that will look at tasks, cpu, memory, disk usage, interrupts, priorities.If I am missing a tool listed then let me know.I am looking for something that can display the results graphically.
I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps). We will use Eclipse IDE and C++ lanuage. I hope the tools are easy-to-use, reliable, popular, better with good supports, and not-too-expensive. I already find a list of tools at WiKi, however, I don't have time to try them all. Could anyboy please recommend me a few? If you can tell me briefly about their pros and cons, that will be the bet.
Recently, my fraternity decided to use our LAN to stream media to our various bars, lounges and ballroom. Some of our playback devices, including an iPhone and a laptop, broke during a party, which is why we decided to have portable devices replaced with sturdy, interchangable and fixed hardware.
As this is going to cost some money and effort, we had better make a fully thought-through plan, which I am in charge of. Still, having never organized a project of any measurable magnitude, I would rather have this plan commented on here.
So far, I am planning to buy one central PC (2GHz, 512 MB RAM) acting as a server, and four identical PCs (1GHz, 256 MB RAM) acting as clients. The former would a) provide local files, stored an an external encrypted hard drive, and b) act as a NFS and SMB client to private systems in the same LAN to incorporate (and forward) data stored on those (as to provide one central point to change the configuration for their use). Futhermore, it would host /etc, /usr and /home of the individual clients to provide that at all times, the same software and drivers are used on all of them. The clients then would mount /etc, /usr and /home from the server, alongside with the both the directories on its external HDD and the ones it had itself mounted from other PCs. Each of them would have to be able to play back music, video files and terrestrial TV from a USB stick, with at most two of them doing so at a time.
Is this a realistic scenario? I so, would you have any recommendations for changes and could you point out pitfalls? The whole lot would have to be rather secure, as usually, there are lots of people coming and going, and we don't want our private data corrupted. If not, where did I go wrong? How would you yourself build a system like that?
And last, what software would you use? Is there a window manager which would be able to act solely as a means to display the three icons needed for TV, video, and music, and make it impossible to tamper with the system? And what programs would you use for playback to ensure maximum performance?
P.S.: Not that I'd suspect so, but is there a german lawyer present? Provided the individual files we play are in our legal posession, this is a legal scenario, isn't it? There would only be friends and other frats present at any public display.
Are there any tricks/sites/methods to use the linux man command in a more convenient way? I love commands in terminal but for some strange reason I preferred to type man in firefox then in the terminal. The output is so long and I have to scroll forever to find what I need. Also the lack of example is a headache.

I've installed OpenSUSE on my server and want to set ssh to log every command, which is send to system over it.
I've found this in my sshd_config:
I guess that both of those directives has to be uncommented, but I'd like to log every command, not only authorization (login/logout via SSH). I just want to know, if someone breaks into my system, what did he do.
Let:Source directory is /x/y/z/src: Destination is /x/y/z/dst, Q: What is the option in zip command, which zip all updated or new picture files (*.jpg) from the source path to the destination + don't keep the original files -zipping while moving- ?
I have been trying to get the advanced graphics for compiz, emerald, and cairo dock working for a few days now, but alas, I have failed horribly. I tried to uninstall compiz and emerald a few days ago (stupidly) and since then, these problems have arisen. I tried seeking help on ubuntuforums.org, but they were unable to help. You can see the entire thread at the following link: http://ubuntuforums.org/showthread.php?t=1694800&page=2
If you want a detailed list of everything I've done, you can go to that site, but here's a summary: I entered a series of code that I was lead to believe would eradicate compiz from my system so that I could go through with a full reinstallation. However, the result was that I now can't load any advanced graphics from emerald, compiz or cairo dock. I've tried reinstalling the entire operating system, but I'm getting the same problem. I also tried a live CD for 10.10, but with the same results.
I don't know if this is a relevant piece of information, but one thing of note is that I typed "compiz --replace" into the terminal and got the following:
Code:
WARNING: Application calling GLX 1.3 function "glXCreatePixmap" when GLX 1.3 is not supported! This is an application bug!

This is an application bug! Again, I don't know if that helps at all, but there it is...
I want to write a shell script which will simultaneously collect OS user information and write in an individual text files.Can anyone tell me the syntax of the script.N.B. The user name will be mentioned in an array within the shell script.
I know that there was some shortcut to see detailed boot process, hardware information. I think it was 'R' but I'm not sure.(I know that I could also remove 'quite' option but this is not the case like also virtual consoles. I'm looking for this particular shortcut and some information what it actually does)
I learnt that there is a way where we can automate the installation of Red Hat using a kickstart script. However, everywhere they talk about doing that from bootable floppy image. I have a single DVD of Red Hat (RHEL5). Can anyone tell how can I kickstart the installation using the kickstart script, i.e., where do I place the ks.cfg file on the disk and what command should be given at the boot prompt? (Kickstart from DVD and not from any network.)
After the latest yum updating, yum hides detailed info about what it will do when it work. Previous version of yum will list the packages to be updated, installed, or deleted, and then ask you if it is what you want; this updated yum show nothing but "Are you sure?"( or something equivalent ): you don't know what it will do at all! Seems you have type "y" and see what it will download and install or uninstall. I don't know if new yum has changed its notice method or if I need add some plug-ins for it to show me those info as it did.
How do I setup some more detailed effects in gnome? In the menu "System / Preferences / Desktop Effects" There are few options. I wanted to be able to do more settings, and you can do in KDE. How would I do that?
I'm running Xubuntu 10.04 and if I am in the detailed view mode with Thunar eventually I will be unable to highlight, select, or take any actions to any item on the list until I switch to another view and back again
