What is the best CLI tool (preferably Linux based) that will allow concatenating video files, and also compressing them on the client-side for YouTube upload?
Thanks
I have just introduced Redis into our application and I am not sure where best to install in production. I read that the Windows option is not production quality so i need to install on Linux.
I currently have 5 redhat boxes and cannot get any more provisioned at this current time. These consist of Active/Passive HaProxy load balancer and a cluster of three RabbitMQ boxes.
Where would you install an Active/Passive redis instances?
I added subdomain,create a new folder,than put some files in folder,when I try to access my new subdomain I get this message 500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
Can someone help me with this please?It is linux hosting with mysql database.
Normally when I read a book I use a bookmark held horizontally under the current line I'm reading to help me keep my eyes on the right spot. When I read a PDF or other document on my computer I would like to be able to do the same thing, only with a line on the screen controlled by the up and down arrow keys. Any suggestions for an application which would do this? I'm a Ubuntu Linux user.
I had Ubuntu installed and I installed XP. I tried to be able to dual boot them by running an Ubuntu live cd and running
~ $ sudo grub
grub> root (hd0,0)
grub> setup (hd0)
But now when I restart I get a black screen that says
'Boot device
Selected Boot Device and press any key
No matter what key I press it shows this error
This is what my system looks like:
/dev/sda1 - Ubuntu - ext3 - 73 GiB
/dev/sda2 - Ubuntu - extended - 3.16 GiB
/dev/sda5 - Ubuntu - linux-swap - 3.16 GiB
/dev/sdb1 - Windows XP - ntfs - 76 GiB
/dev/sdc1 - Stuff - ext3 - Code/Documents
/dev/sdd2 - Stuff - ext3 - Movies/Music
I have 4 VMs on a Linux host, call them A, B, C, D running on Z. I really don't care when A and B come up, but I would like to make sure that D comes up before C.
I believe that in VMWare 2.x it's possible to change the boot order. Is this possible in 1.x as well?
Is this done in /etc/vmware/vm-list? I see that there are a number of VMs listed there, including some that have long since been deleted.
I'm running Xubuntu, (actually linux mint with xfce on top, but I suppose it's essentially the same thing)
I set my appearance theme to (a modified version of) MurrinaStormCloud, but if I run gitk, it uses ugly font rendering, ugly colors, ugly widgets.
I think tcl is the thing to blame here, but can I fix it?
Here's a picture for comparison between what firefox looks like under the current theme and what gitk looks like:
If I ssh to a remote machine and then lose internet connectivity, the session freezes.
I can't control-c or otherwise abort and go back to my local xterm or terminal prompt but if I wait several minutes it will do so.
There must be some way to force it to abort the remote ssh session when connectivity is lost.
I'm on a Mac but I believe this happens on cygwin or linux as well.
Can I have different .bashrc files loading when logging into different nodes that share the same home dir?
This is, I am mostly interested to loading different PATH directories when logging as bash, depending on the different Linux nodes I log into? For example, if I log into bash in machine abc-01, I would like to have a given .bashrc loaded, but when I log into abc-02, that uses the same /home/username directory, I would like to use a different .bashrc. How can I go about doing that?
What would be some of major use-cases in which you would want to assign multiple IP addresses to your NIC?
Knowing of any standard/well-known 'gotchas' associated with each use-case would also be helpful. For example, I heard someone saying that a user with access to such a machine will automatically get access to both networks, which could be a security issue.
You can assume a Linux-based environment.
I need to load the module pcspkr to Linux kernel often by sudo modprobe pcspkr.
It sometimes happens that something goes totally wrong such that I cannot stand the amount of decibels in my speakers.
I would like to
control the amount of decibels in my speakers
and to have a visual speaker in my top panel which indicates the amount of decibels in my computer at each given time
How can you solve at least one of the problems?
It seems that the canonical instructions for making a bootable USB flash drive that runs memtest are at:

However, after following them to a T, I boot up the new machine and get:
"could not find kernel image: linux"
Do I need to set up a lilo.conf first?
Hi - I'd like to be able to have one set of users authenticating using public key auth and the other set to use username/password. Is this possible in OpenSSH on Linux? If so how do I go about it? Right now, I'm stuck with only having one option as far as I can see in /et/ssh/sshd_config - it's either PAM or PublicKey authentication...
I am new to Ubuntu(and Linux for that matter) and I am trying to access files using the terminal. The network folder is on my Desktop, but when I go to the Desktop folder via the terminal, the network folder is not there.
How do I access files on a network folder via the terminal?
I have a few DRb services running on different windows machines and they can all connect and talk with each other just fine. When I put these DRb services on Linux machines and try to connect from windows nothing happens and I get a DRB:ConnError ... the service on Linux is never touched. So I did a netstat on the linux box and the service(port) were not listed anywhere even though the program is clearly running. Is there someting that I'm missing when talking to DRb services on Linux from a windows machine?
I have a .bkf backup file, created by the Backup utility that Microsoft provides with Windows XP. Is there a way to read the contents of the file using a non-Microsoft OS, preferably Mac OS X or Linux?
I created a partition in my hard disk for my data (documents, multimedia, etc.).
How can I:
Move the /home/ directory to the new partition
Make the OS (Ubuntu Linux) treat that directory as the default /home/.
I have Linux installed on my harddrive, sometimes I run it as the host operating system and sometimes run it as a guest in Windows using VirtualBox. It's a nice ability, I think.
I don't think it's possible with Windows though. Is it because your average distribution includes drivers for everything known to man? Are devices/drivers configured statically in Windows so when somethings changed it breaks?
I'm trying to understand what the benefit of running redis as a daemon is. The redis default configuration seems not to run redis as a daemon, but locally on Mac OS X I added it to LaunchAgents, so I'm guessing it is running as a daemon anyway?
Also on my remote application which is running on a linux server, since it won't have LaunchAgents (as far as I'm aware) will I have to run redis as a daemon? What will be the benefit of doing so?
I would like to deploy Xen virtualization, however I definately not sure which way to go.
Citrix Xen Server has (AFAIK) better managment tools, but does not provide software raid.
Ubuntu / CentOS has Xen installations and support software RAID.
Is it worth to go and buy HW RAID or just stick with SW RAID and Xen budnled with linux distribution.
Which way would you suggest? Are there any other things I should consider?
I've been working with linux for a while but in a rather simple manner.
I understand that scripts in init.d are executed when the os starts but how exactly does it works?
How does the os know which paramater to pass to a script?
To start apache I would do sudo /etc/init.d/apache2 start. If I run sudo /etc/init.d/apache2 it doesn't work without the start. How does the os pass start to the script?
What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong?
EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man
So far I have tried Firefox (latest and greatest) and Chrome (also latest and greatest), and while Chrome runs faster than Firefox over X11 from my CentOS server to my Windows 7 workstation, it's still pretty sluggish.
What other GUI browsers are available for Linux that would [likely] run faster than Chrome?
I've not tried Opera 11, but have had many issues with it under Windows and Mac OS X directly, so am waiting for a new version before going that route.
Suppose that I am in a private network of computers (say each having ip addresses 192.168.. ). Some of the machines( we have no information regarding their ip, name and no physical access to the servers) in the network are connected to internet and they run an http proxy at some port say 3128.
Is there a program which can be run on Windows or Linux which will give me the list of machines(ip addresses and ports if possible) acting as proxy servers?
I'm devellopping a WebApplication (for Tomcat) using netbeans on Windows 7. For the Webapplication to run I need to run a insall-script once.
This script (*.bat for windows and *.sh for linux is included in my war-file (WEB_INF).
Now everytime I deploy the WAR-file and want to run the script on linux I have to call
chmod +x install.sh
first.
Is there a way that this script can be made executable by default? I don't want to have to execute some extra commands after the deploy to make the script executable.
For clarification:
I'm not new to Linux and I know how to set executable-rights on files. That's not the problem. My problem is: What do I have to do, so that this script is executable right after tomcat deployed my *.war-file (unpacked it). If I would be using Linux for development as well, I would try to set the rights according in my sources (maybe I'll try it when I have a little more spare time). But I am using Windows and netbeans.
Are there any attributes I can set to achive my goal, or is it possible to achive this using ant?
By the way: Are there security related issues with this approach? The script looks for java executable and calls a javabased GUI-installer...
