Debian :: Migration Check List - To Check - Prepare Or Reconfigure
Feb 3, 2010
I am new to Debian but not Linux-based systems. I have been experimenting a lot with Debian Lenny/Squeeze. I am growing more comfortable each day with the Debian design. Yet there remain many unexplored areas. I am creating a migration check list. Things to check, prepare, or reconfigure when moving from one Linux-based system to Debian.
I have a good computer background and my current check list probably is fairly good. Yet I would appreciate input and opinions from experienced Debian users of things to watch in such a migration. Login defs, passwd/group files, different directory locations, keymaps, services and daemons, etc. I am not too concerned with the desktop as I plan to stick with KDE 3.5 for a while and I can basically move those settings across.
I have a text file with a long list of RPM's. I need to check if each RPM is installed. I'm sure I can cat out this file and run "rpm -qa" against it, but I'm having trouble with the syntax right now...
I want to know that is there any command by which i can check which type of hardware devices are installed in my Linux box like SVGA,Sound Card,LAN Card.
I m using pidgin2.5.5-1 that is old version of pidgin because of some proxy issue, I dont want to update it anymore but it keeps on showing its update in package updater its very annoying...How could i get rid of it ?I want package updater show all updates except this...that is permanently remove it from update check list.
In my project i cannot determine the number of check list initially. I will know dynamically during execution.How to specify the number of check list dynamically in zenity.
I am trying to install ubuntu 10.10 on an eee pc 1000H but the installer is hanging on the installation dialog that shows the check list for installation (min disk space, connected to the net, plugged in to wall outlet, etc).
I've been google'ing around recently for some good solutions for creating local yum "update" repositories without syncing entire repositories. (or adding hundreds of exclude statements in config files)
I have several boxes with a common base build (centos 5.5/x86_64), one has nagios3, another has apache, and another tomcat6 (also a couple of others) For tomcat and nagios I'm obviously using 3rd party repositories (jpackage, epel, rpmforge to name a few) Everything is installed via RPM from kickstart.
I would like to make an updates repository which contains the updates for everything that's installed (including centos base).
Updates will be downloaded on a separate box, but not sure how to get the list of packages required on that box where the packages are not actually installed. I've looked at reposync and mrepo, but appear to be syncing from what's available rather than what's required.
I was hoping that I can provide an "rpm -qa" output, compare this to a "yum list" or perhaps running "yum check-update" on a list rather than installed packages. I could then use the yum-downloadonly module to get the packages which have changed from available sources.
i am making the shift from centos to debian as i have heard that debian has lot of packages compared to centos and can make you learn more,i want to know how can i match the md5sum provided on the download page with the DVD images
It calls for libhdf5-openmpi, which is not compatible with libhdf5-serial which in turn is used by several packages that i have installed...
It's either the serial or the openmpi version... not both.
Since this specific package from sid calls for this dependence, which way do i have to check that if i override dependency checking it wont overwrite anything along the way...?
All other dependencies can be met... except this particular one...
And i wont be using the functionality that calls for openmpi...
Below is the recipe I've used to compile dwm from source on Squeeze
su apt-get install devscripts debian-keyring apt-get build-dep dwm exit
It all seems to work, however debuild gave an error about secret keys. Is this a sensible procedure? What happens in the (probably unlikely) event there is another source patch?I've gone to a tiling window manager as the result of the purchase of a wide screen LCD monitor. I like to have some stuff down the right hand side when running Firefox and OpenOffice in the main panes. Any configuration tricks welcome. Modern screens are the wrong shape!
I am not sure whether I ask this question on the right forum. My debian mailserver is depending on a MySQL database. Every reboot it takes around 30 minutes to boot because of the database check. I could not find the right command or setting to boot without this check. Do you know how to do this.
But, given that I've mixed some source and unstable packages in with my stable system, I'm now experiencing a few eccentricities (which really should make me swear off screwing around with my system, but, alas, I don't seem to learn from experience).
I digress. Anyway, in trying to play cdroms (with xplaycd and with kaffeine), it does not work. Kaffeine gives me the following feedback:
Code: The host you're trying to connect is unknown.
Check the validity of the specified hostname. (unable to resolve)
Is it possible to check out the log as well when you are checking out a version from some repo. For instance this is a game I like :-
[Code]...
The game is called dawn-rpg and one can find about it at dawn-rpg.sourceforge.net but that's not what I want to talk about. The thing it would be so much more convenient for me if instead of going to the svn mirror or whatever it is and checking out the log, it was local. I know I could do something like this :-
svn log > svnlog150611.txt
This would download the log file and put the contents in some text file I have named as svnlog150611.txt . The problem with this way of doing things is that each time I have to check out I would have to create a new txt file with that date. If there was a way one could check out the log as well when checking out a new version/release it would be nice. Its also possible that this might be already be there and there might be another command to use locally that I am not aware about. In that case, would look forward to people to share the same.
I want to install Debian Stable 8 Jessie. I've tried the main website, of course, first. But there are a lot of options there to download Debian 8: CD, DVD, Live etc. I downloaded debian-live-8.0.0-amd64-lxde-desktop.iso and I booted live in VirtualBox. It boots fine and the operating system looks in order.
Questions/problems:
1. The desktop icon for the installer says "Install Debian sid". But from what I know "sid" is unstable version. I do not want unstable, nor testing. I just want normal Stable. Did I got the wrong version? The website is a bit confusing about which version is which.
2. How do I check the md5 of the iso? I know how to do that with other distros, they usually specify it near the download link and I can execute in terminal the command 'md5sum' followed by the specific linux distro iso and then compare the numbers. But I can find no such thing for Debian. I searched the website but could not find any clear info.
3. After I install, what should I do in order to make Iceweasel work with Flash and multimedia codecs? I also need Skype and the proprietary Nvidia drivers.
And if I enable these non free, do I get automatic updates for them like for the rest of standard Debian software? Or, if not, what should I do?
The idea is that I want a system that is as stable and bug free as possible, but I won't use many apps beyond these ones. I don't need the latest and greatest software as long as these get security updates. Should I be ok with this configuration?
Also how do I check the latest version available? I gather to update a driver I need to update the kernel so ill not be doing that but im trying to get more familiar with linux here. I know how to do this in windows so it would be good to be able to check driver versions in linux too. Im on debian 8.1 with intel HD4400 graphics.
How do you check if a computer's video card will support Kernel Mode Switching BEFORE OS installation?
In this example I have an Acer Aspire AST180-UA381B.
Manufacture website says my video card is: Integrated nVidia MCP61
[URL] ....
Nouveau code list says: NV4C (MCP61) GeForce 6150LE / nForce 400/405, GeForce 6150SE Quadro NVS 210s / nForce 430
[URL] ....
I want to know:
1. How to tell if my graphics card will support KMS before I install the OS?
2. If it does not support KMS which kernel options should be passed to get it to work properly with the nouveau driver?
3. Ultimately I am looking for a tool that should be included in the installation screen that will:
a. identify your hardware: list the hardware detected on the screen b. highlight with color code any hardware listed that is not supported or poorly supported: in this case graphics drivers c. perform a quick benchmark test of your hardware: In this case I want the benchmark to tell me what capabilities my graphics card has. d. automatically recommend and set the best kernel parameters for a successful boot: if the graphics card needs nomodeset or modeset=0 or whatever I want it to do it for me.
Also I started a personal blog about this issue which I intend to compose into guide to assist others with this question. [URL] ....
My goal is to create a boot disc that will automate proper installation of graphics or other hardware for a system BEFORE installation. I would like to see this feature included in the Debian installation screen.
I'm using Debian squeeze and for an assignement, i have create 2 virtual pdf cups printers. Both are working very well. To test the different administion command; i try to disable one of the printer and move his queue file to the second one. I'm able to do it easily.
Now, i wish to write a bash script that wil test the status of the printer. So that,if the printer is disable, it just execute the "move" script. Is there a way to know the status of a cups printer and use that information in a script?
For example, a command/function that can return "O" is the cups printer is enable and "1" if not.
I've created a new group and a new user called dftp... Now I wanna do one thing... If 'dftp' connects thru ftp he should be directed to a particular location... and he shouldn't be able to see other folder except for his own including the parent folder that contains that location... I changed dftp's home folder to the location I want. However while connecting thru ftp. user dftp has been given permissions to see other folders and check out the contents of the other folders.
