Ubuntu :: Speed Limit - Burn Data CD At 8x Only?
Jun 13, 2010
My DVD player attached to my TV is picky. Burn CD's (with avi files) at 8X and it plays them. 16X and it complains about bad disk. Every time. In karmic, I can only get cdrecord to burn at 16x.
Here's the command:
cdrecord -dev=/dev/scd0 -speed=8 -dao -pad -v something.iso
And it burns at 16x instead of 8x. Command issued with root privilege. Identical hardware under CentOS 5.x and it burns at 8x, like I asked it to. I'm all SATA if it matters. What do I need to do to get the version of cdrecord with karmic to burn a data CD at 8x? For whatever reason, CDs burned at 16x just don't work in the DVD player attached to my TV.

i both have the same problem, i'm trying to burn my images at 4 or 8 speed, but ubuntu 10.04 says that the hardware does not support that kind of speed and switch up to 16 speed and more. i know it can burn at low speeds, at least in windows, it is a bit strange that fast burning is okee, and slow not, what can i do to prevent this? i don't wanna burn to much errors on my discs

It sounds weird but on Linux I can't find a browser that allows to set a download speed limit. I found an extension for Firefox but it works only on Windows. I know the existence of download managers like d4x, wget, jdownloader, etc... but some downloads can only be done by browser. I know trickle too but if I want to change the speed limit I have to 'restart' the command (interrupting the current download). Then I didn't find an extension for Chromium.

Is there a way to limit the speed that apache will send a page to a specific computer in my LAN? I would like to be able to test what my pages would be like if they loaded at 25KB/s for example. My Server is 192.168.0.2 and the other 'browser' computer is 192.168.0.4.

We (3) have download limit problems with a 50G/month limit (Inc uploads). The router I cannot change, and it offers no useful options. So I am considering using IP forwarding from my own box. I think I would need a second nic, & router. Eth0 would run a dchp server, eth1 would run a client. What do I run on the box to monitor downloads & uploads, and is there a way of adding pc & laptop downloads to limit luser downloads? Does this stuff strangle speed? I'm running slackware-13.1

I have a linux debian on a network connected to a router through a ethernet cord. My linux is hogging the network speed and the users of the other computers on the network aren't very happy. Is there a way to limit the download speed on only my computer?

I am trying to limit bandwidth of certain ip addresses on my server. I have been doing hours of reading and not getting very far... So far I believe the iptables command is
ptables -A PREROUTING -s 178.33.23.44 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.45 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.46 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.47 -t mangle -j MARK --set-mark 2
and now I just need the tc command to read those marks and limit bandwidth, I have a gigabit connection and would like to limit each of these ip addresses to 10mbit in and out.

I use vsftpd. I would like to know if there is a way to limit the upload speed. Only the upload speed so the "anon_max_rate" and "local_max_rate" don't do the job. Someone told me about the trickle but I expected a more recent application.

I have this new flatmate who uses all my Internet data up before the end of my monthly clockover. Instead of having to buy heaps of data top-ups at the end of the month, is there a way I can limit the speed of his computer through the network? I have tried looking through my router settings (which is a Thomson router) but there doesn't seem to be any options in regards to limiting activity of a system on the network.

I'm using Brasero to burn DVDs and I'm burning at 4x speed (the DVDs and the DVD burner both support 16x max). The problem is that while burning, the speed is too low and it jumps around between 1.5x and 2.4x. This seems weird to me.shouldn't the burn process fail if it drops below 4x or if the speed is as unsteady as it is? But the DVDs seem to turn out fine anyway.

I need a program that will limit download speed per connection. So that each download is limited to 100kbit/s for e,g. I tried trickled, it only limits whole application (and doesn't work with firefox). Also tried pyshaper, doesn't work. Is there such software?

In my household a number of people use the internet. Up to a maximum of 3 wired connections and 2 wireless connections at its peak, all connection through my D-LINK G604T router. The problem is, when one person is downloading or watching ..... or whatever, the others using the internet suffer. I've spent hours configuring QoS on my router, and long story short, no matter how I configure it, it just simply does not work. QoS in no way shape or form limits connection speed (which it says it should). Anyway.
I have a spare computer under my desk, and I'd like to know if I could set this up with a (free) linux distro that limits bandwidth speed per connection. For example, of the 1500 kb/ps (about) my modem pulls, is there a way to limit that to 768 or 512 per connection? so person A can still download, person B can still watch ....., and person C can still play counterstrike with a latency under 100. This would solve many, many arguments in my house I am *fairly* good with computers, but if the distro came with documentation and a GUI that would be awesome.
* TL;DR: *
Is there a linux distro I can load on a spare computer that limits bandwidth per connection, wireless or otherwise, with good documentation?
Failing that is there firmware I can use for my modem (dlink g604t) that would do the same?
Failing that do you know of any good hitmen that would solve my family arguments, ahem, permanently?

I have a PC that is using Ubuntu Karmic. It serves only to download stuff, and is on 24-7.
Can I set a limit to download speed for Deluge and aMule throughout the day (so that it doesnt interfere with other network stuff) but unlimited during the night? (when we are all sleeping)

Trying to burn a folder full of stuff to back it all up. I've tried both Brasero and K3b, and neither will do the trick, even though they both successfully simulating the burn. Not getting much feedback on why the burn won't work - K3b says OPC failed, probably doesn't like the medium. I've tried to do the job with plenty of CDs now, so I don't think it's down to dodgy disks.

I am unable to burn data cd's. I tried both k3b and Brasero. Both of them seems to be burning but about 70% through both say unknown error and ejects the cd. I am using cd-rw. I tried different cd's but the error is the same.

I can't burn a data disk through Ubuntu.I tried using the built-in disk creator, It had some kind of error saying the disk cannot be mounted.So I used Brasero instead and I got essentially the same error. When I tried to open both CD's the files appeared to be present but were all corrupt.Braso works fine for burning music CD's but I can't get it to work for data.here is the error log from Brasero:
BraseroReadom stderr: Time total: 131.474sec
BraseroReadom stderr: Read 666760.00 kB at 5071.4 kB/sec.
BraseroReadom stderr: HUP
BraseroReadom process finished with status 0
Session error : Some files may be corrupted on the disc (brasero_burn_record brasero-burn.c:2862)

I was wondering if there was a Windows or Ubuntu way to limit the amount of data that is able to be sent over the internet between certain times, eg. Between the times of 7am and 7pm can only download 300 MB from the web, when this limit is reached the web is either disconnected or slowed down.

I'm running UbuntuStudio 9.1 on my Toshiba Satellite laptop, and all other aspects of the operating system and software are fantastic - absolutely love it!I am having a serious problem with Brassero though for recording to CD. I can erase any of my re-writable cd's just fine using it, but when it comes to trying to burn a cd with it - Brassero goes through all the motions of putting the info onto CD, finalizing and then briefly displays the box saying "completed" but then immediately goes into "creating image checksum" and keeps busy doing that into forever - last time I stopped it after 35 minutes! that's absurd.
Maybe it's because the laptop has a CD/DVD combo drive, not sure, but I need CD burning software, and that is for sure.Can someone recommend a different software package that I can use to burn CD's covering everything from data to music?(or possibly help me fix whatever is wrong with Brassero?)

When I try to burn a data DVD with k3b it errors out telling me...
Unable to find the following files: /home/ion/.kde4/share/apps/RecentDocuments/Mon oncle d'Am+�rique (Resnais, 1980).srt.desktop
...but when I invoke (as root)...
# ls -al home/ion/.kde4/share/apps/RecentDocuments
...it retruns...
ls: cannot access home/ion/.kde4/share/apps/RecentDocuments: No such file or directory
So is k3b lying or ls?
Before you ask, fsck gave no errors. But Find files/Folders from the Application Launcher menu finds and lists it in the RecentDocuments directory as above, then tells me it is "Inaccessible". Delete does not work from GUI or CLI.

the software will go through the motions and say burn successful and all the disc itself will even have look like its been written (with the burn circle and all), but when its put into the drive afterwards its still empty. My fstab has
Code:
/dev/sr0 /mnt/cdrom0 auto users,rw 0 0
/dev/sr1 /mnt/cdrom1 auto users,rw 0 0
for my drives. Both of them do this, wondering if anyone has any idea why it might do this. I know the drives both work fine.

Forgetting bad past experience (in debian i386 and amd64), I have newly lost a new DVD in trying to create a data disk with brasero with debian i386. After successful simulation at the lowest speed, burning failed and I expect that the disk is no more good (this occurred in the past). In the past I complained with debian, getting no answer.
In contrast, I tried k3b with full success. However, as a gnome user, installation of k3b brought in so much of kde that proper use of gnome was prevented. Can anyone tell of an installation of k3b that does not hinder gnome? In particular not the startx procedure (as I normally work without calling the x server).

Now, I use Fedora Core (version 8) with core linux OS 2.6
I have some file data with size about 2G and I want to burn (write) this file to DVD rewrite.
I know linux OS can install software to burn data to DVD, but I don't have permission to install more software. I only use command line over Terminal (Gnome Terminal).

My machine has 4 SATA 2 West Digital 1TB disks. I made 2 partitions on each of them, 500GB for each partition. When I started using them I check their I/O using iozone. The first partition has 100MB/s for read, 70MB/s for write. And the second partition has 80MB/s for read, 55MB/s for write. All 4 disks has the same result.
As I use on, the I/O speed on each partition decrease, to different extend. For example, for the 4 first partitions, the write speed varies from 69MB/s to 56MB/s. And I have same amount of data on each of them, all used 11%.
My guess for this is the disk block allocation policy. This is caused because some disk starts writing from inner location while others writes on the outer edge, even though amount of data on each disk is the same.

I have a need of a database, and the information to go into it. I know how I want to organise my data for optimal cross referencing, but what I know is merely what I know and I do not know if what I know is what is known...
Madness to say... looking at my database I see this is the best way to organise the data, but what I do not know is how the computer will respond to my methodical madness.
Is it quicker to have one table with many fields or many tables with few fields?
We've got information for 10 users with 17 idiosyncrasies.
So, would one table with 17 columns and 10 rows... or... a group of 50 tables with one column and 3 rows and one table with 4 columns and 5 rows...
Be more efficient concerning:
QUERIES...?
Searching?
Comparison?
Insertion?
Deletion?
Modification?
The queries and modifications will be daily, and constant. These numbers are really much larger but the math is easier for me to articulate on a smaller scale. I use Perl, php, and C with SQL for management.
