I'm looking for a way to access the raw data on a CD.I have a small program that I'm using to play raw PCM data pushed into stdin.I'd assumed that I could just use:play-pcm < /dev/cdromBut this isn't producing any data.Will I need to do this programatically or is there a simple way for me to grab raw data from an audio cd in the same way I might do so for a data cd?

We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
//------------------------------------------------------------
char m_readBuffer[255] = {0};
char* p_curChar = m_readBuffer;
[code]...
I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.
I'm having trouble with my optical drive (an LG GH22NP20).I can read a data DVD, but when I put in a standard audio CD it does not recognize it.I hear it spinning around in there, but if I check /media/ there are no files listed.?

View 1 Replies View RelatedOn my Mac, OS X Snow Leopard 10.6, I copied my itunes music files onto my external hard drive, which is HFS+ formatted (as FAT32 just wouldn't cut it for the other files that are on this drive, mainly 1080p video spanning several gigs on a single file)..
Here's the problem, Linux doesn't have ANY permissions it seems to access it.. I did nothing special on the Mac side, just drag and dropped all the files over.
As a normal user I can't open the folder. As root, I can go into the folder, but still can't access the files themselves!
I can't write to it either to change permissions because HFS+ is read only.
I need these files IMMEDIATELY, and I need to know how to do this now.

View 5 Replies View RelatedOver the last few years of using Linux as an alternative to That Other System, I started with Red Hat 9 and moved on to FC3. I have no web access with RH9, and FC3 no longer has audio. It used to, but I recently was obliged to do a fresh install, and up2date no longer does anything. I suspect this is because FC3 is so old. I need the updated kernel in order to have audio. Time to move on. I see that Fedora Core goes up to FC11 now, and I was wondering if anyone had suggestions as to which of the more recent FC distros is better than the others, or, alternatively, which one(s) to avoid?
View 5 Replies View RelatedI have a server which had one drive in it that was using LVM. I removed it and moved it to the secondary bay in the same server, then installed a fresh new blank drive in the primary bay on this server.
I then installed CentOS 5.2 on the new drive. During the partition phase of the install, I partitioned my new drive and MAY or MAY not have removed the LVM from the second drive and left the partition there, not sure exactly what I did.
After install I wanted to try to mount the old drive so I could access the files on the old drive. The /boot partition shows up when I do a df -h but not the / partition where everything I need is stored.
When I look at the drives in Webmin, the second drive is there and shows up as LVM but has not LVM name.
Basically what I need is on /dev/sdb2.
How I might be able to mount this partition which seems to still exist when looking at webmin.
I have been tasked with accessing data stored on a WD Sharespace drive. I have a machine running Fedora 13 at my disposal to do this. So far I am running into dead ends. The drive is connected via Ethernet, but I have never accessed a network drive in Linux before.

View 9 Replies View RelatedA while back I've been playing with the idea of setting up one of my machines as some sort of data server and would like to access it through SSH. I've already conducted some tests through the wireless router and apparently on the software side there are no issues with the SSH thing. I also noticed that since the same adapter was in use (wireless) SSH 'fought' with the Internet for the bandwidth
In order to avoid the aforementioned problem and also in the spirit of enhancing security I am thinking of setting up the following network scheme with two laptops and two routers (a wired and a wireless one):Both laptops would receive the Internet service through the wireless router. Both laptops would be connected through their Ethernet ports to the other router. The wired router wouldn't be connected to the Internet. Would this set up allow me to use SSH only through Ethernet thus eliminating possible bottlenecks in the wireless network? I am operating in the assumption each machine would have two different IPs (one per router), is this correct?
For some weird reason (default network device?) when I connect the Ethernet cable to the laptop, although NetworkManager claims to be still connected to the wireless network, I can not connect to Internet (the wired router has no Internet BTW). But if I unplug the Ethernet cable the Internet continues through the wireless network.
I figured I could just go in to my Kubuntu desktop and look at the drive. But it has only a lost and found and grub folder with a few files on the root named config-[version]-server (note this is a SCSI). Guessing I'm looking at the boot partition? So how do I mount the other partitions? When I do a fdisk -l I see 3 sdb 1,2,3 (2 and 3 are large, 1 is my boot partition) but when mounting them I get wrong fs type. I was sure its ext3 ( also tried 2 and 4 )? I just left the default 7.04 fs when I installed it. I'm able to put it in my desktop and my server but for the life of me I can figure out how to get at the data.

I've got an old EIDE hard drive that used to be used for a dual-boot WinXP and Linux (not sure what version - either RH9 or FC1), and I'd like to pull some data off it. That computer died, and I reformatted the Windows partition, but left the Linux portion alone. My current Linux (FC10 + XP) computer uses a SATA hard drive, and I'd like to get the data from the old drive to the new one. I've connected the hard drive normally, jumpered as a slave drive. Linux now boots normally, but I can't access the older hard drive. I tried the techniques in the following thread: [url] and commented there (with more info), but I thought I would be more likely to get a response by starting a new thread.
Here's a summary of what happened: ran "fdisk -l": the command saw both hard drives ran "tail -f /var/log/messages" and got the following: Jul 30 16:00:44 localhost kernel: EXT3 FS on sdb8, internal journal Jul 30 16:00:44 localhost kernel: EXT3-fs: mounted filesystem with ordered data mode. Jul 30 16:00:44 localhost hald: mounted /dev/sdb8 on behalf of uid 500 sdb8 was a FAT partition I had set up for moving files back and forth between XP and Linux (none of the other partitions were reported). ran "vgscan", which only returned one volume group When I ran FC10's Local Volume Management tool, it sees the hard drive and its partitions, but reports them as "Uninitialized Entities".
Yesterday, I upgraded to the 10.04 verion of xubuntu. Looks fine. However, I keep my data on an NTFS partition of my dual boot laptop, and am finding that I can't access it.
I have a symbolic link to that mounted partition, and when I click on it, I can see the first level of folders, but I can't execute them (even though they seem to be set to 777) and I can't open anything...

View 7 Replies View RelatedBefore the other day, I'd copied a live CD to ramdisk and run it from there before, but the disk was INX (INX is not X), a live CD based on Ubuntu that runs entirely in the text mode, no GUI. INX is a terrific product: colorful, educational, light, agile, fun to use, and and often damned useful, but when an OS only uses text, you may not notice how much running from the RAM speeds up an OS. Previously, I'd assumed that the best reason to run a Live CD from the RAM was to free up the CD ROM drive. When I started running a full KDE 3.5.10 Desktop from the RAM, it didn't take me long to notice the awesome boost in speed and performance.
The computer has the fastest access to the data that's in the RAM. (The "A" in "RAM" stands for "access", right?) So the machine is faster. As the RAM gets larger, I'm sure more and more live CDs are going to offer the RAMdisk option. Right now both INX and SLAX share the characteristic of being exceptionally small CDs, and that makes them well suited for this kind of application. The "minimal" version of Slax, the basic CD without any modules added, is less than 200 mbs, which fits very nicely on my 1024MB RAM. I now use the minimal SLAX cd to initiate the system, and I keep a collection of the modules on my hard drive to copy to the RAM and activate at will.

I am trying to access data that is on a Raid 5 array in Ubuntu... There are 4 installed disks (250gig disks) - 3 of which are setup as a Raid 5 array (the 4th is active but unused). These show up as one large drive (498gig). I have had an issue with the drive where it is no longer allowing Windows to boot - I receive a disk read error on boot (so the OS does not load, obviously!) - what happened was basically I unplugged then replugged in one of the disks which affected the array... I physically reconnected everything as it was, I then had to 'reactivate' the disk in the Raid BIOS... at that point the array seemed OK, was the right size, etc (and was listed as "Optimal" in the Raid BIOS) however, the problem with the disk read error persists.
I have started the machine using Ubuntu v9.10 from a CD (non-destructive mode) and it shows a disk of the right size (ie: on the desktop and in Nautilus it says "498gig Filesystem" ). However, in Nautilus, the disk appears empty with no folders or files on it (even with hidden files shown).... If I view 'Information" for the disk it shows 67gig used space and 399gig free space (which is correct). Also, if I view the disk in Gparted, it shows a disk with about 67gig of used space and 399 free space on a 464gig disk (with 8gig unallocated). One more thing.... when I try the command 'sudo dmraid -tay' it says that there is no raid disk (there are in fact, no drives plugged into IDE or SATA slots - all disk are plugged into the RAID controller card). Anyway, at this stage, I just want to copy the data to a single hard disk if possible and move on.
