im trying to send pages of 4096 bytes from kernel layer of server to kernel layer of client over a network. previously i tried the foll. code , for data less than a 100 bytes it worked fine , but for something larger than that the computer hangs......(even the dmesg's wont say why) i also wanted to know how we could use the 'sendpage' function to solve this problem.
Every time I right click on my CD/DVD with my DVD+RW popped in the drive, it freezes for like 10 minutes and then it unfreezes with nothing happening.I think I formatted it before using ImgBurn but when I did it went from 4.7GB capacity to 3GB. Is it possible that I accidentally turned my double-layered DVD to single-layer? If so is there a way to turn it back to double-layer?
seen this or have suggestions on how to fix this. I can read the original disks but I cannot read the backup. The backup disc was burned on Window$ using Nero.I am trying to read the disc using both VLC and Totem but you can see in /var/log/messages there is an issue with reading the disc. This disc is readable in the Window$ box and on all DVD stand alone players.

I'm using Ubuntu 9.04 and I cant read dual layer DVD's. When I put the disk in it spins and makes clicking sound sometimes. It shows up in Places as "Myfiles". If i try to mount it it "DBus error org.gtk.Private.RemoteVolumeMonitor.Failed: An operation is already pending". If i try to eject "DBus error org.gtk.Private.RemoteVolumeMonitor.Failed: An operation is already pending".
I use Bluewhite64, a Slackware64 derivative. Next, I don't use KDE or GNOME. What free tools (command line ok) would do this job? Examples would be nice, too. Most of my HD recordings are approximately 7 GB.
I have downloaded both the 32 bit and the 64bit version of slackware, I have a dual layer dvd and I was thinking to put both versions on one dvd! I just want to be able to choose which one to install with a simple menu. How can I do this?
Am slowly parting company with MS Windows. I have been using this app to convert, burn, and then be able to play on most all DVD players, ConvertXtoDVD. Is there something I can use in Ubuntu that is fairly easy? Also would like something in Ubuntu to convert and burn to Dual Layer media and then play on standard DVD players.
Having some troubles with NEC AD5170A device - it can`t read any dual layer disks. First layer reading is ok, but when drive switching to second layer it stops and don`t read any data from disk. Media - licensed DVD video disks. Same drive in windows read everything. I try to update firmware, but it doesn`t.
I've been interested in Synfig for a while. In the last version of Ubuntu, there were some problems so I couldn't install it. Yesterday I remembered the program and decided to try it on 9.10. I was amazed, it installed fine and everything worked just how it should. Then later last night, I must have done something because everything turned invisible and when I created a new layer or shape, nothing new appeared.
I fiddled with it for a while and then reinstalled the program a total of like 3 times just in case that would help. Then, I went straight to the Synfig site and downloaded the newest version. It looked better, different, but it behaved exactly the same. I'm very confused and I would like to use Synfig, it seems amazing. I assume there's some little thing I missed or something I pressed that I shouldn't have. Here are screen shots of both versions.
I try to watch flash content but everything is covered with a pink layer... (see attachment file). I am using firefox 18.104.22.168 (same prob with opera!) and flash 1.0.2.r152 in ubuntu 10.10 with compiz disabled and GPU Override set to true (no difference with false..) I tried FlashAID for a clean setup and I have only flashplugin-installer on my laptop (no gnash or libswf...), I also tried it with the package "adobe-flashplugin" same problem. This and the a2dp-skips are my last problems before a perfect setup.
When I try to play a dvd and give mplayer no options, it defaults to "X11" for the video output, which maxes out the cpu. To get around this, firstly I tried to play the dvd using "cvidix" in the console.
I used the following command: mplayer -ao alsa -vo cvidix -fs -framedrop -stop-xscreensaver -dvd-device /dev/dvd1 dvd://1 This played the dvd, but the console text was still visible over the top of the movie; i.e. mplayer was playing in the layer beneath the console text
Then I tried using xvidix in X: mplayer -ao alsa -vo xvidix -fs -framedrop -stop-xscreensaver -dvd-device /dev/dvd1 dvd://1 This gives a green line about 5mm thick down the right side of the screen, but other than that it is ok.
I am looking for a layer 7 firewall. I have to redirect rtmp requests for different hostnames coming at a gateway to internal servers at LAN at their respective hostnames. Code: IPTABLES some stuff -p rtmp -hostname to server 1 like that. Or if not IPTABLES then some other feasible solution.
I want to know the IPsec-Advantages and Disadvantages that arise because of its location on the network layer in the OSI-Model. I read rfc2401 and rfc4301 specifications to find out the advantages and disadvantages of IPsec being located on the network layer in the OSI-Model (equivalent to Internet layer in the TCP/IP protocol stack). I really could not find enough good reasons for the advantages and disadvantages of IPsec being located on network layer. Here are some of them that I could think of:Advantage: - No application-specific implementation is needed (in comparison to SSL/TLS) - The ability to connect two subnets on the internet (tunneling mode) - Ability to encrypt the traffic between two end-points (transport mode)Disadvantage: - Complex implementation of ipsec itself - High computation performance when AH and ESP both activated - No encryption for the packets to the destination if it is arrived on the subnet on the other side when tunneling mode is activated.
(the network traffic is no more encrypted inside the subnet)What else can you guys add more to these advantages and/or disadvantages? The focus is IP-sec location on the network layer. (it is a kind of comparison to ssl/tls which is upper layer protocol)I would be grateful to any responses.P.S: I hope that this thread has landed in its right place.
Im new to Fedora and im already loving it. I only have one problem and that is that I can't play mp3 files. I use Rhythmbox 0.13.1 and it starts but when I play a mp3, It says that in need a mpeg 1 layer 3 plugin. I already found a tutorial that says that i need to install these.
I want to write a new protocol on transport layer. These are the features that new protocol should include:
-Real time -Concurrent transfer -Multipath and Multihoming
the reason why i should write this protocol is in order to transport encoded video stream over 3G link. When i investigated TCP UDP or SCTP source codes, i couldnot understand them at all. What ı want is to help me about steps of the protocol writing or guideline about it. How should i start, is there any book or source about it (i couldnot find over my internet research).
I issued the command 'mkisofs -dvd-video wss.iso ./juan', where the dvd-video files in ./juan/VIDEO_TS made a total of 7.5GB. Later on I'll use the image to burn a double layer dvd. But mkisofs, after working up to the middle of the process, said: 'File size limit exceeded'. I don't want to burn on the fly and therefore
I want to implement a cross layer approach. I want to pass the network information such as delay from the MAC layer to Network layer. Can you tell me the way I am new to this. I am using linux (fedora). I think some system call will do the trick. Correct me if I am wrong. (I want to implement QoS matrices)
I've downloaded some files from the Internet Archive. They come in different file formats and most of the time I use pdf. However, sometimes the scans are saves in colour instead of b/w. This makes it difficult/impossible to read on a dedicated ebook reader. In that case I downloaded the djvu files as on the PC you can select which layer (color, bw,fore,back) one would like to see. Selecting the bw gives excellent results. However, the ebook reader does not has this option.
The question is, how can I remove /extract a layer from the djvu file and save only this layer.
So far I've tried the following two approaches:
1) select bw in the djvu viewer on the PC and printed to postscript file. Followed by a ps2pdf conversion. This works, but generates a fairly large pdf file. Sure, I can again upload it to any2djvu but it just seems to much manual work for each file.
2) I tried the shared annotation feature and said (mode bw). This works on the PC as desired but is ignored on the ebook reader as the other layers are still present.
I backed everything up and did a complete re-install of the system to 10.10. I had a widget layer with compiz before I did this and now it is not even an option in the preferences. Am I missing something?
I was running 10.10 before as well and it was there.
