General :: Good Book / Manual To Read To Learn More About OP Systems?
Mar 25, 2011
What would be a good book/manual to read to learn more about linux o.p. systems? and how to use them.I have to add I may not have such a good internet connection I might end up with free dial up (Bummer)so I'm not sure if a link will do.I will end up at the library anyway. so if you could suggest something that would be good, I'm not really looking for the history but more like how to use, maybe the terminal and such?.
I'm built an distributed application, and now I want to take some metrics to show how my application works. These metrics includes the time of computation, the time of communication and the amdhal law. I would like to know what tests can be done to show the performance of the application. So, I'm searching for a book or document that shows me what type of tests can be done to show the performance of an application.
I've no experience with IPSec. I've used many times OpenVPN (with static key or certificates x509). Could anyone suggest me a good tutorial in order to learn IPSec vpn with Linux?
I am working on arm systems that has embedded Linux this system has this specifications:
Quote: 1-64MB memory 2-400 MHz arm cpu 3-embedded linux kernel (2.6.29.4) I am looking for a good known database that: Quote: 1-has low memory usage 2-support PHP and C API
I restore tape backup on my Linux server. At the time of booting the server it cannot able to read the filesystems.
I am getting the following message, Code: Your system appears to have shutdown uncleanly Forcing file system integrity check due to default setting Checking root filesystem fsch.ext3: file system has unsupported features (S) (/) e2fsck: Get a never version of e2fsck! (FAILED) *** An error occurred during the file system check. *** Dropping you to a shell; the system will reboot *** when you leave the shell. Give root password for maintenance (or type Control-D to continue):
I don't know why but on Ubuntu 10.04 I can't find manual for read bash command (invoked with "man 1 read").There are manuals for C++ functions, but not for bash command...However, I'm still able to use that particular command in my scripts.Is read command deprecated, I miss some files or is this a bug?
I want to learn shell scripting. So where to start and what are the prerequisites? Are shell scripts portable among different linux os? (Does a script written for CentOS, run on Fedora or on Ubuntu without any modification?)
I have been working on CentOS from the last 6 months. I want to know that which scripting language is best to learn.I heard about Python and bash scripting.And I think Python is fastest among others.
The last time I wrote code for anything was about 15 years ago using Turbo Pascal. I would like to get back into it, most likely to create some mobile apps or enhance web sites. What is the best general purpose language to learn? And what is a good method for learning, preferably free?
I am trying to learn shell scripting and came up with a lil first script that I could actually use.I have a basic shell script and all it does is run:
sudo apt-get update sudo apt-get upgrade
So basically just a shell script that updates your packages. NOW, my question. I made another shell script that makse a bit of a menu and asks what you wanna do, 1 to UPDATE or 2, to CLOSE. How do I make it so when they enter 1 it runs my update.sh ?
I am just starting to learn Linux and am interested in a career in Linux. Actually I wanna go for RHCE, which is the first step for Sys Admin..right?? Basically I do NOT want to go into programming/developing as I don't feel it's my cup of tea (and also may be it sort of boggles me). Still, from what I gather I am having confusions regarding whether I should learn any programming language for a career in Linux.
Here I am avoiding programming..and now I get to hear that Linux career uses programming..That's sort of frustrating...My friend told me I need to "master" C. Do I need to learn some programming language?? If yes, then to how much extent?
I am very new to Slackware and Linux. I was able to install and run Slackware 13.0. But I have no clue to install anything to Slackware. Can some one kindly explain step by step how can I install pidgin-2.5.9-x86_64-1.txz ?. It will be a great help. How can I learn Slackware?
I would like to learn basic linux commands and editors (eg : vi). Am using windows and it is difficult for me to install linux in ma laptop. So is there any free linux login servers available in internet so that I can login to server with putty and try using basic linux commands and editors.
My predecessor wrote a perl file that is run manually twice a month to send a set of emailed reports to one of our clients. My boss has requested that I look into automating this; it seemed simple enough, and I thought I had it set up, but I'm running into a rather strange problem.
Both the emailing program (in perl) and the report files themselves are kept on a Novell server reached from our Linux box via /mnt/srv/path/to/file/. From the linux box, I can see and manipulate them fine. The files are displayed as having 755 permissions across the board. The Linux box itself is running SuSE 9.3.
A manual run of the emailing program works fine; the files are sent out as expected. However, when I tried to set up a crontab entry for this, I'm running into trouble. I manually edited /etc/crontab to include a line setting the program to run at '0 21 * * 1,2,3,4,5'. The program itself runs fine, but errors out every time it tries to attach a file; the error message is one that various perl sites indicate means 'could not read the path to this file'.
What's the difference between a cron run and a manual run? What are some possible reasons the former fails and the latter works?

ive been trying to setup nfs share across my network. i have 3 boxes one mac which uses samba to share to the 2 sabayon linux boxes which does work. however the 2 linux boxes cant share with each other or the mac. i have tried differnt variants of the export file such as 192.168.0.0/8, 192.168.1.0/24, *, sasquatcheian etc... after any change i execute etc/init.d/nfs and exportfs -ra, i have rebooted both computers several times. i setup reserved ip's on my routers lan setup page for each computer. 192.168.1.32 is my server 192.168.1.127 is my client along with 192.168.1.38 the mac.i disabled the firewall on the server and the client has no firewall.
trying to install a dvd of Openbook, a distribution of ebooks from the gutenberg collection. running debian lenny amd64.i have multi and uni in repositories enabled. equivs is installed, as well as libglib1.2ldbl libglib1.2-dev and libglib1.2-dbg. i looked in /dependencies/deb/ folder on the dvd and found these packages gdk-pixbuf_0.22-1_i386.deb and gtk+_1.2-1_i386.deb. tried to install gtk+.... after finding synaptic shows no gtk+ packages, only gtk... with the expected error that i am running the wrong version of debian to install x386 apps. looked online and found that lenny amd64 will run 386 apps in compatibility mode. how does compatibility mode work?
Going through book, "Guide to UNIX Using Linux". I am doing one of the projects that has me writing scripts to join files. Here is my pnumname script and I am extracting the programmers names and numbers from the program file and redirecting the output to the file pnn. I then created a joinall script where I am trying to join the files pnn and pnumname and redirect the output to pactrep. When I run the script sh joinall and use less to display the contents of the redirected file pactrep, I get an error- join: extra operand `pnum' Try `join --help' for more information.... I went to the man pages but I still (obvious) do not have a solid grasp.
