I'm currently going through,what is essentially a Linux+ course. I don't like any of the exercises in the book, as it's outdated and doesn't really thoroughly teach how to implement a lot of stuff.Is there a program or suite of programs out there where I can create a few VM's with their own IP's, users, files systems, etc. so I can setup up Samba, NFS, NIS, etc.?

And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.

I simply can't figure things out. I can't say I'm new to Linux but I can say that I am quite new to openSuse and the RPM world in general.

I'm interested in testing Maverick, (or the next release, or the one after that) but always run into a problem with testing that runs alone the lines of.I have my current install (10.04) I have two partitions, / and /home, it works well.As soon as I add a new version it seems to be recommended NOT to have them both point to the same /home partition, the problem is, if I don't do that I don't have all my files, and it's a pain in the rear to setup.So what I was thinking is to have three basic partitions,
/
/home (for config files, and true HOME files)
/data (for all my actual data)
Create links from say /home/james/documents to link to /data/documents that way I can get to my documents.This way if I add a new version I can setup either the same (two partitions, / and /home and point /home/xyz/documents to /data/documents) or keep it slightly simpler for testing, just have one partition and repoint /home/xyz/documents to /data/documents.The main one I can think of would be permissions for files/folders?

View 2 Replies View RelatedI need to run two instances (i.e run the program twice, with two separate windows) of Audacious. This is for a play where I need to have music and sound effects going at the same time. I could do this while running Fedora 13, but after upgrading to 14 the audacious package was updated and now can't do this. My attempts at downgrading have been unsuccessful, and I need the audio done by tonight (the last rehearsal). So... am I up the river without a boat, or is there a fast solution? I'm open to anything, as long as the music player has advanced controls (play, pause, stop, fast forward, rewind, forwards track, backwards track) and can have two instances running at the same time.

This works locally, but I need to get it to work through SSH and I have no idea how to do that. The relevant portion of the script is below. It would also be nice to find a way to not need the full path to the executables but I'm not real concerned about that.So anyone know how to make this code work via SSH?

How to submit multiple jobs onto a Linux server. The only way I know to submit and run a job on a server is using qsub, and verifying the status of the job using qstat. I usually run my scripts using qsub -cwd so that I can run it on my own directory (instead of having the results sent to a scratch folder).
1. However, assuming qsub/msub are not available, is there another way to do it? What commands can I use instead?
2. I know that some jobs can run in the background, is that an alternative? How do I do it? And would I still be able to check the status of the job or delete it?

I am in the process of running some benchmark tests on a variety of RDBMS, I am testing three different client operating systems.Would it be terrible to partition the HDD and install Ubuntu, Windows 7 and Solaris 10? If I do not do this, I will likely have to re-install the O.S numerous times due to changes in the database server o.s as well. The same question goes for the server; would it drastically effect the performance to install 3 server o.s on one server?

View 5 Replies View RelatedDespite the history file is unique (~/.bash_history) I see that the multiple bash processes run on different windows are not all updating that file. I presume that the bash is not taking into account this possibility (multiple bashes on multiple windows) and writes thus the history file in a simple straightforward way. This would mean that a number of history entries are lost. I've tried to find information but had no luck so far.

I currently am running 10.04.1 and have successfully setup my home web server to run a single website. My current settings are:
-I have registered the domain name annarrankings.com through godaddy
-A record is - host = @ and points to = 71.114.220.3
-CName is - host = www and points to = @
-on my server I have the site running in /var/www
I've done some research and found that to run multiple websites I need to setup VirtualHost.
-So I created a folder /var/www/annarrankings.com and moved my site to that folder
-Edited Apache2.conf to add the following line
-I then went to /etc/apache2/sites-enabled and copied the default file to a new file called annarrankings.com. Here's the annarrankings.com file after I edited it
-I then created a link in /etc/apache2/sites-enabled to the annarrankings.com file in /etc/apache2/sites-available
-Next I editied /etc/hosts
-When i went to enable the site using a2ensite annarrankings.com I got the following
I figured this was ok since I had already created a symbolic link earlier (a result of trying to following multiple tutorials and ..... videos at once) so I reloaded apache2. I created an index.html file in /var/www/ just for testing purposes and when I load www.annarrankings.com I get the file located in /var/www/ instead of the website located in /var/www/annarrankings.com Do I need to change my A record or CName in godaddy or did I just do this completely wrong?
This may sound stupid but I've got to ask. Can I connect multiple computers running Ubuntu & run software from one computer from the other? I know how to connect using SSH & to copy files back & forth but I don't know how or if I can share programs.

View 4 Replies View RelatedI have a project for my computer class, and I was a bit ambitious with my ideas and am wondering if I made a smart choice. I need to learn sooner or later anyway! I'm a beginner when it comes to scripting but I'd like to learn more advanced stuff. When I say basic I really mean basic among all basic. To give you an idea I only know some simple HTML and Python. The idea I proposed for my project goes as follows:
The challenge we were given is to create a spreadsheet of data from a website given to us. Points are given for creativity and simplicity in how we go about doing this.After taking a look at the site (or rather, html files given to us), and with having dabbled with Python before, I came up with what I thought was a pretty good idea.The pages of the "site" are just numbers. They go from 001-117 .html in terms of filenames. Their source code has some sort of table set up, and the information we are pulling off are easily found by the tags that precede them (the info, btw are the periodic elements).
The tags are pretty obvious, and state pretty much what they are labeling. My python knowledge is almost nonexistent but I figured that would be something Python would be capable of. Why do I post this here? I'm relatively new to Ubuntu too but keep hearing about bash scripts and such. Would this be even better? (Perhaps it's silly but I'd like to use Ubuntu to accomplish this)
Or is there an even better scripting method/language I should be using? Could anyone give me some pointers in how I could accomplish this? I'm really hoping to learn a lot from my first "real" scripting experience!
I'm looking for the most pure linux terminal distro. I am trying to learn linux and I have Ubunutu 10.10 installed but I feel like it's not as pure as other distros, like Ubuntu 10.10 is different from the average terminal experience.
Maybe I am wrong about this, but certain things like the grub .lst file is now a .cfg file in Ubuntu, is this replicated across all linux, or is this unique to Ubuntu? Little things like this that make it difficult to learn. Are all the distros unique in this way?
Suggest me the best book for learning more about directories in ubuntu filesystem
