It's as simple as below where you just specify the dev device of the CDROM which is usually /dev/sr0. You can boot actual bootable discs like Windows, Linux, etc straight from a physical drive this way.
sudo qemu-system-x86_64 -cdrom /dev/sr0 -m 4096
The strange thing is that usually the first install or two will work on any new machine but then it suddenly won't. I had this experience on QEMU 2.13 on a different machine. There is something finicky or buggy about the CUCM installer even when choosing the same virtual hardware specs.

Many people are aware of the "eject command" which works as you would expect.
To eject the disc:
sudo eject /dev/sr0
To insert the disc again you still use the same command but with the "-t" close try toggle:
sudo eject -t /dev/sr0
#mount the VCSA DVD
mount /dev/sr0 /mnt/cd
#alternatively you could mount the iso directly
mount -o loop vcsa.iso /your/mount/path
#for this purpose we are using the CLI installer on Linux
#no it's not going to be that easy you can't just run vcsa-deploy like that you need to use a template or configured .json file
Usage: vcsa-deploy [-h] [--version] [--supported-deploymen........
I've never seen this before in all of my years. Ihave some very old CDs and DVDs 12-15 years old that seem not to work in this BD-R/DVD-R/CD-R Asus drive.
The discs are fine actually and ironically they even work fine on a normal LG USB based BD-R drive!
Here are the errors in Linux:

These errors believe it or not are simply because of not being the root user or running with sudo! However if you didn't know to try as root you'd think there was a problem with your burner or disc Essentially it looks like without root you cannot send the required scsi commands to continue writing. Ithink cdrecord should have built-in tests or safeguards to see if it has the permissions to run the required commands.
I guess for more advanced users the idea is simila........

sudo mount -o user /dev/sr0 cd
You need the "user"option otherwise non-root or non-owners cannot view the CD and this would make it so no anonymous access to the CD/DVD mount would work. Note that most distributions including Ubuntu DONOT work unless you manually mount and share as shown above (Icouldn't find any other way in Ubuntu).........
find / -name 'thedirectorytofind' -type d
That's all there is to it and now you don't have to get a listing of all the files along with it.
Another cleaner solution that supports wildcards is the following
find prep-*/dvd-slideshow_temp*/ -type d
In my case I already copied the VIDEO_TS folder to my hard drive.
Here is the command for mencoder:

Replace "-dvd-device myvideobackup/VIDEO_TS" with the location of your backup files or the /dev device of your DVD drive.
The -o myvideobackup.avi is of course the name o........
It really is as simple as:
cdrecord -v dev=/dev/sr0 pathtoyourisoimage.iso
-v is for verbose, I prefer it but if you don't you won't see as much output like below (I like to know the details and exactly what's happening)
dev=/dev/sr0 specifies the device name of your burner (they say not to use it and to specify some weird annoying device string but using the raw /dev has always worked for me and is how it should have been implemented from the start IMHO)........
My Samsung drive failed on me, at first I thought it was the enclosure but a direct SATA connection causes the same problems for discs that are inserted. It will work fine for a few minutes but then starts spewing the errors below.
I've never been a fan of Korean made optical drives and have always had trouble with them. The problem is that I don't believe NEC and Lite-ON make drives anymore, and I considered them the leaders.

My mother needed a new laptop and I recommended her the same one I would have bought myself or my wife, that means the cheapest possible laptop with the most features for the money.
This HP shines at this price point and one thing that made me stay away from buying more and recommending HP/Compaq was the poor battery life. Not anymore, this model has an industry leading up to 4 hours of battery life.
Key Factors for Choosing It:
I finally decided to look into some utils that did this, and the first one I found is "mp3burn". It is unbelievable simple and perfect. *2017-11 update and mp3burn is still available in standard repos such as Ubuntu 14/16 so this is a current and working project.
Just install the package and it gets all required libraries to convert and then burn's on the fly. And you won't believe how simple it is.
I just want to a directory that had the MP3's I wanted t........
I took an educated guess because it kept happening at the same spot when loading the XP install. I thought it was the hard drive or motherboard.
But it turns out my heavily used but loved NEC 3500 DVD-RW drive was the culprit. After disconnecting it and swapping it for another much beloved Pioneer DVD-RW, everything has gone smoothly.
I never ran into this or many issues because I've hardly used this drive since moving it to another Desktop years ago. I actua........
The folder I was trying to archive is about 72GB, but much like rsync at about 17GB it chokes because of the filesize. What's with so many common and essential Linux tools having such limitations? I guess it is likely that the authors never wrote their code with the idea that files would be so large but it's still very annoying. It's important to stay on top of these limitations on production servers because I didn't realize what happened until I checked the file with "........
DVD Burners and Media at an all time lowThis is crazy you can buy a nice Pioneer DVD burner for like $64 CAD now and good media like 50PC Maxell is just $25.97 at Walmart.
I'm liking this. Time to make double archives of important data :)........
CDR Manufacturers - Why is so much media bad?I have searched for good media and tried many kinds for years. I guess I'll try to summarize my findings and conclusions.
Dye is irrelevant, dye of any color can be good or bad, it more likely depends on the manufacturer.
Speaking of manufacturers, the name at the top of the disc means nothing. For example, Memorex along with any other 'brand' is actually always made by another manufaturer including CMC Mag........
What is your favorite CD and DVD manufacturer?Everyone has their favorites. What media has provided you the best results?
Personally my favorite is Taiyo Yuden, if you buy Fuji's made in Japan they would be Taiyo Yuden. Basically any disc made in Japan is likely a Taiyo Yuden and for me they have provided the most consistent results.........
How do you copy a DVDHow do you copy a DVDI'm assuming you mean how you can backup your DVD titles?
If you are talking movies, you should use AnyDVD and CloneDVD, they are excellent tools for backups.
For data CD's, Nero has a DVD-Copy option and that should work well for most purposes.
Hope that helps. :D........
NEC ND-3500A is great!I just picked up an NEC 3500A a few weeks ago and I love it.
It is a great all in-one optical drive solution.
It can burn DVD/+R-R at up 16x, read at 16x and rewrite at 4x and CD-R at up to 48x!
Not bad, but the impotant part is that it delivers consistent high quality burns and the drive is as quiet as I could ask it to be.
It's also convenient that it has a lot of hacked firmware for overspeeding of........
This will give you the basic info needed to browse and connect to Samba shares from the command line. From the GUI of Gnome or KDE etc, it is pretty standard and straight forward. However, I've found very little guides on how to do it from the command line and if you're like me, a nerd who prefers command line for its simplicity and for remote use, this is the way to go.
First get a list of all the Samba/SMB shares on the target.

There's a lot of outdated information and confusion for system administrator's out there.
One annoying task for many an Administrator has been backing up data in Linux. You don't need any GUI tools such as K3B or GnomeBaker. Both are excellent tools but for veteran command line users working remotely, using the keyboard is a great and possibly automated way to save yourself pain and hassle.
At a later date we'll cover how scripting can automatically backup certain........
