Server :: Automating Linux Administration Through Web Interface
Aug 5, 2010The question that I am posting here is quite interesting as it was asked in the interview I attended today. And, honestly, I could not provide a solution. Ok, here goes the problem statement:Design a Web Interface that has three text fields:
IP Address:
Subnet Mask:
Default Gateway:
And a button:
When we click the Submit button, the two entries must be set in the concerned files and then the network service must be restarted to bring the new IP Address, Subnet Mask, and Default Gateway in effect.As we all know that these settings can be done by the root user or a user who has those priveleges.The complete web interface needs to be done only in PHP. Some Shell Script can be used if required.
Ubuntu Multimedia :: Can't Get Any Sound From My Audio Interface
Nov 1, 2010I recently got a new audio interface, which is working perfectly on ubuntu 10.04 i just plugged it in and it worked without any tinkering! the interface is a lexicon omega which is fully supported under alsa. The problem is that for some reason it's not working on ubuntu 9.04 (which is where were most of my work currently is so occasionally i still have to use 9.04 as i don't have all of the same software installed on 10.04).
Jack seems to detect it properly in both 9.04 and 10.04 as it is listed in "interfaces". But it does not show up in "Volume Control Alsa Mixer" so I cannot select it from the drop down list.
So currently I have no sound (just in case you weren't able to decipher that from my primitive ubuntu-speak above )
Here's the output of cat /proc/asound/cards

Ubuntu Multimedia :: 4-pin Firewire With Audio Interface - Don't Provide Any Power
Dec 12, 2010I had originally planned on buying a USB 2.0 audio interface to use with my first home recording studio, but it sounds like Linux support is pretty horrible for these devices. On the other hand, the FFADO project seems to be very promising, so now I'm looking at getting a firewire interface. The only problem is that all I have on my laptop (sony vaio VGN-N365E) is a little 4-pin firewire port. If I'm not mistaken, those don't provide any power. Will this work with any interfaces (maybe one that has it's own external power adapter)? Or is there an adapter I can get to convert it to a full firewire port and add power?

Feb 18, 2011I own a Tascam US 122l USB audio interface. I just figured out how to run this thing with jack. Unfortunately the (output) sound is very very choppy and I am not able to use the volume control at all. how i could fix that? Or is there maybe a way to use my interface without jack and directly through alsa?
View 6 Replies View RelatedUbuntu Multimedia :: Sound Distorts In Ubuntu 10.04 With External Audio Interface ?
Nov 1, 2010I have an external audio interface that is supported by alsa and works really well with ubuntu 10.04. The only problem is that on my studio monitors I can clearly hear that the sound from ubuntu is distorted, like there is too much gain somwhere. Since my audio interface (Lexicon Omega) has an output level knob on the interface, ALSA does not have a level slider (software) through any mixer (eg GNOME ALSA mixer).
In order to stop the distorting sound problem, ie the signal input to my external audio interface is too "hot" first install PulseAudio Volume Control (referred to as pavucontrol in repos) in PulseAudio Volume Control configuration tab, set "profile" of your external sound interface to "off" log out, and when you log in again your problem should be solved.
Fedora :: Can Use All-in-one Printer With LINUX Operating System?
Nov 24, 2009Can I use my all-in-one printer with LINUX Operating System? KODAK All-in-One Printers are designed to to work with WINDOWS XP, WINDOWS VISTA, WINDOWS 7 Operating Systems and with MAC OS. Because of its open-source nature, LINUX OS requires a complex, dedicated support team. LINUX OS represents a very small percentage of installed operating systems in the U.S. As a result, costs for ongoing support and a dedicated support team are not justified at this time.
As Kodak continues to launch products, and as updates are made to LINUX OS, launching LINUX Drivers would require ongoing support and driver updates to Kodak's software. Customer support teams are focusing efforts on current issues concerning the more prevalent WINDOWS and MAC OS; adding support for LINUX OS would take resources away from these issues. Compatibility information for KODAK All-in-One Printers is printed on the retail package so that our customers can be aware of the printer's hardware and software requirements at the time or purchase. For more information about specifications and compatibility, visit KODAK All-in-One Printers.
General :: Boot Linux System On USB-stick
Apr 20, 2011I have installed a Debian System on a removable USB-drive just the same way I would do it for a normal harddisk drive.All was working fine until I tried to boot the system.I have set up the USB-stick as first boot device in the BIOS, and written grub in the MBR of the stick.When trying to boot it, "Grub Error 2" will always be risen (I am using grub-0.98).
The only drive I have installed except the USB-stick is a SATA-harddisk, so normally the USB-stick is called /dev/sdb.I have already tried changing root in menu.lst to (hd0,0) or the kernel root to /dev/sda1 but nothing seems to help.

Ubuntu Servers :: Reboot The System With A Linux CD To Do The Backup?
Mar 1, 2010I have a personal ubuntu server that provides apache, glassfish, firewall, routing, email, CVS, MySQL, etc.... This server has been running for a while with two hard drives configured into a RAID 1 array. The array has two partitions, one for swap and one for the data. I currently back up the data with a removable hard drive. I use dd and create an image of one drive and the MBRs (partition tables) of each drive.In a disaster situation I can use this data to recreate one drive and then re mirror it to the second, or just boot the back up.I like this solution because I can easily recover from bare metal, and the backup is transparent. I can browser it if needed since its an uncompressed image of the drive. The one drawback is that I need to reboot the system with a linux CD to do the backup.
My hard drive space is almost at capacity. So what I want to do is add a third drive to the array and migrate it to RAID 5. However this will cause my current backup method to no longer work. How can I back up this RAID 5 array. I need to back up the entire system, and not just the data. I have made many tweaks to the system over the years that it has been running that I can't lose if a restore is needed. I have seen a large thread here that people have been using tar. My concern with tar is how do you use a tar archive to restore a system to a new array. Im assuming that you would need to setup the array and then just restore the archive? Also, i don't have much faith in using tar on a running system. Doesn't this open yourself up to corrupted backups? My second idea is using rsync. While I consider myself experienced in linux from 10 years of personal and professions use, I have not had much experience with this utility. Would rsync provide a more reliable way to backup a running system that would enable a bare metal restore later? I once read something about people using rsync with hard links to create a backup that could store many incremental backups.My main concern with both rsync and tar is not being able to restore the OS to the state that it was in at the time of the backup.
Ubuntu :: Linux Working Only Rebooting System From Windows XP
Feb 11, 2010I have noticed that ubuntu 9.10 (but also other distro and in general those that configure the network automatically at startup) crashed if my pc boot directly with a linux kernel at power on.This does not happen if the first boot is done with windows xp and then rebooting the pc and choosing the same linux kernel.Some distro (for example SysrescueCD) that does not configure the network at startup can work but also with these if I try to configure the network using the command ifconfig eth0 the system crashes.My network card is a SiS191 Ethernet and linux recognized it using sis190 module.I suppose that something happen during the first power on, some inizialization done with windows xp but does not done with linux in fact after a reboot made from windows xp without shutdown the pc, with Linux I can configure the network using ifconfig without crash.
Any ideas to solve this without have to boot always windows as first?
Networking :: Do IP Addresses Belong To The Interface Or To The System
Apr 14, 2010The subject has the big question. I've read answers both ways.The kernel has documentation that says the IP addresses belong to the system. Yet the configuration works as though they belong to the interface.Shouldn't we have it just one way and stick with it ... and make everything work that way?
If IP addresses truly belong to the system, then a command to configure an IP address should not need (and not even accept) the name of an interface. The only exceptions would be link-local addresses (which by their nature do suggest being interface specific ... and they should be autoconfigured by the kernel, anyway). Interfaces would only need to be brought up or down.

View 1 Replies View RelatedHardware :: Building System - Interface With Car Sensors And Controls
Jun 25, 2010My parents have given me a free pass to play around with their old Saab 900 Turbo and what I'd really like to do is put a small linux computer in there as an experiment (and application, ultimately). For this to be a realistically useful project I really should make it interface with all the cars sensors and controls e.g. speedometer, fuel gauge, mileage, thermostat etc. I assume that since these are analogue meters they use an electromagnetic dial? It should be possible then (and without too much effort) to hook it up to an input device like the Arduino? I don't really know because it's been a long time since I studied electronics properly. I've already found a touch screen, I'm fairly sure I know what computer I'm going to use (SheevaPlug) and I'll probably use debian with xfce for the OS.

General :: System Does Not Recognize Audio CDs.
May 21, 2011About two days ago I installed Bodhi Linux on my machine. I like it because it's fast and small. Anyway, I have two issues: I can't get the system to recognize any of my audio cd's, or my USB drive. I don't even get a notification that there is anything in my DVD drive. The other issue is that I am unable to go in and look at my hardware configuration from the main window.
