Is there a way to get DVD region code from command line (linux/ubuntu 9.10)?
I want to script this action and store the region code (and other data about DVD) in a log.
I am using Centos5 running on a VMWare but whenever I choose to open the User Manager menu from System-Administration, an error message always displays
The user database cannot be read. This problem is most likely caused
by a mismatch between etc/passwd and /etc/shadow or /etc/group and
/etc/gshadow/. The program will now exit.
I am a Linux novice and have no idea how to fix this tiny issue. ANy help is thankful. Thank you.
I need to forward any http request from my old server IP to my new IP.
I migrated servers and there are a few domains that have a high TTL and I could not update.
Is it possible to take all HTTP requests from one server running centos/whm/php/apache 2+ and forward them to the new ip?
Since I have hundreds of domains I'd prefer a solution that involves running an app on the linux box that will push requests automatically to the new box.
Thoughts?
Cheers
I would like to boot directly from an external hard disk to improve performance over my internal notebook hard disk. My notebook has no native eSata jack but a pci express card.
As my BIOS doesn't support the card on boot time so no way directly booting it.
My question is, is it possible to work around this issue by using an USB stick or similar with a boot loader like grub and if so, will this only work for Linux or Windows as well?
I am pondering on what would be any implications in logging in via SSH as root?
Surely SSH is safe or am I kidding myself and falling for the unwary ethic of logging into a remote Linux box as root?
Thanks.
Hello I am new to ubuntu linux and am currently trying to configure my netbeans to work with PHP. I have found several tutorials to install all the applications I need and have installed a virtual directory for netbeans to run in. Unfortunately, whenever netbeans or I myself go to my local host I get an error 403. I tried modifying my settings to allow from localhost (instead of allow from all) but this did not work and am completely out of ideas.
I've been able to use this linux command to connect Netcat to a serial port:
nc -l 80 <> /dev/ttyS0
I would like to be able to log this transaction. My backup plan is to use Wireshark to monitor the netcat stream, but ideally I'd like to do something like this:
cat /dev/ttyS0 | tee upstream.bin | nc -l 80| tee downstream.bin | /dev/ttyS0
This tries to open ttyS0 twice and therefore throws a permissions error. Does anyone know a smarter way to do this?
I'd like to force myself to use the correct (right side or left side) Shift, Ctrl, and Alt keys depending on what letter I'm typing. For instance I'd like to use the right Shift key when typing 'A' and the left Shift key when typing 'P'. I find myself using only the left side a lot and I'm looking for a way to set the mappings on my machine so that it only responds to correct pairings. I'm running Fedora, but any Linux distro support would be an acceptable answer.

I have 2 linux machines, they do not have internet connectivity or any other means of getting an external clock.
I need one of them to act as the "master"/server and the other machine to sync it's clock to that server. It's not important that the time is correct, it's only important that the time is the same on these 2 machines.
So, give I have a server (192.168.1.10) and a client (192.168.1.11), how do I set up /etc/ntp.conf on these 2 machines respectivly ?
I'm in the process of migrating to a new server, but some traffic that should be going to old server is now coming to the new server before I am ready to migrate. My provider used an IP used as the secondary nameserver on the old server as the primary IP on the new server, so now my secondary nameserver is directing traffic to the new server.
Is there a way to forward the traffic hitting the new IP back to the old IP while I wait for DNS to propagate?
Server is Linux CENTOS 6.5 x86_64 w/ cPanel
Thanks
Today after unpacking the initramfs file from my Linux /boot directory I found that it contains the GenuineIntel.bin file, and that that file is an image of what is called the CPU microcode.
Then I found articles on ArchWiki and Wikipedia describing the subject. Now I'm not sure that my vague understanding of the subject is correct.
Can anyone please explain what the CPU microcode is in plain English?
Can anyone tell me how to access the Java Applet Console in Chromium for Linux?
I assumed there would be a Java application packaged with the JRE that would give me access through the command line, but I can't find reference to anything.
$ java -version
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.2) (ArchLinux-6.b24_1.11.2-1-i686)
OpenJDK Client VM (build 20.0-b12, mixed mode)
The main file shares on our network are currently hosted by old Apple XServes. I had planned to replace some of these with Windows shares as I have better hardware available but have been told this is likely to cause issues with some of our Mac users.
What sort of issues am I likely to run into and what are the recommended ways of hosting general file storage in a mixed OS (Windows, OSX, occasionally linux) environment?
I have a slow machine, mainly a Celeron with 250gb HD.
I'm planning to install a Linux distro and create a bunch of VMs for development.
Which distro should I choose? I plan to use this machine mainly as a small "hypervisor" to other vms.
Is it possible? What do you suggest?
Thanks!
Hi there,
We are looking setup our own yousendit equivalent for our user as well for our clients! what is open source software to use, we want web interface as well email. We are looking setup using centos do any one has done some thing link this pls share with us.

I have a laptop with a 250GB HDD. I have an existing installation of Kubuntu across three partitions (A 20GB one for /, 2GB for swap, and something like 97GB for /home). If I add another partition, use that as / for a Mint 13 install, and then use the existing /home partition as Linux Mint's home folder (different user names), are there any dangers (besides badly done partitioning, and other dumb things like that)?
I'm trying to figure out how to use the linux "find" command (or another command that will get the job done) to return a list of file paths/directories that do not contain a directory of a certain name.
~/web/domain1.com/public_html/bar
~/web/domain2.com/public_html/
~/web/domain3.com/public_html/bar
~/web/domain4.com/public_html/
I want all of the paths that don't contain the directory named "bar" (domain2.com and domain4.com). Any idea how I can get find to output such a list?
Thanks!
I have Virtual Box 3.1.4 installed. Host - Snow Leopard(Mac) Guest - Windows 7 (32-bit).
I have installed Windows on my MAC because I need it for work. I cannot establish VPN connection (using NAT).
I tried to use bridged adapter, and I lost my internet connection on my guest(wind7) completely.
I don't know much about networking, so I need detailed instructions for his particular OSs. Could someone please help me with this?
Some random details about my attempts:
On my host Windows I get error 800 trying to VPN.
I can ping server address from my guest Win 7 and I have VPN connection established from my host Mac.
I do disable VPN on my Mac when tying to establish it through guest.
I tried to VPN from Mac and see if Guest sees it. It doesn't.
Thank you!
Hi,
I'm running a Linux server that - from time to time - faces heavy load and the conntrack table overflows. Since it's iptables firewall ruleset is very simple I'd like to turn it to stateless mode. I know that iptables can operate in stateful connection tracking mode and in a stateless mode.
My firewall rules are all in place I'm pretty sure that they are stateless but my question is how can I verify that the firewall is really operating in stateless mode?
I have a pretty busy GNU/Linux server that I think needs more RAM. I know that the free command doesn't show the amount of RAM that is used.
So I was stumbling upon Commited_As in /proc/meminfo. It currently shows 57972 kB which isn't much. Is this the amount of RAM that the processes use "right now" or is this an estimate of how many additional RAM it would take to never run out of memory with this load?
In command line, we have, for example, TAB, which autocomplete the commands.
In the GUI, we need just to select a text for Ubuntu to copy it. And the mouse middle button can be used to paste.
Which other "untold" secrets Ubuntu hides?
obs. I don't know which of the items I told are for any Linux or Ubuntu specific.
I'm trying to setup a network architecture where one network is a low-latency low-bandwidth tcp control system (GBit), the other is a high-bandwidth udp (maybe tcp) network that could get saturated (GBit).
If I have two NICs inside a server running Linux. What happens to the low-bandwidth/low-latency network when the high-bandwidth gets saturated. Does each Ethernet card get the same amount of priority inside the kernel or would the low-latency network suffer from the high-bandwidth being saturated?
Is there an application like Wubi for other Linux distributions?
More specifically, I'd love to install Fedora without a dedicated partition or changing my bootloader.
