Networking :: Sessions Locking Using Jumbo Frames?
Sep 8, 2010With Mellanox 10G NICs and the MTUs set from 1600 to 9000 we have tcp sessions hanging. Executing ls during an sftp session just hangs. The same thing happens for an ssh session, if execute ls I might get few item in the directory but then the session hangs. Like wise for FTP. The Fujitsu switch is configured by default to handle jumbo frames. At 1500 MTU everything works fine. We are running the 2.6.25.14 kernel with CentOS 5.2 and the Mellanox driver.

Sep 27, 2010I was able to build a NFS server and a NFS client using OpenSuse 11.3 and connect them together using gigabit ethernet through a switch. These are the only 2 devices on this net (192.168.1.xx). I tried to set the MTU to 9000 and 9014 but learned that the Realtek 8169/8111 only support up to about 7200 MTU. So I inserted Intel NIC cards on both and set both to 9000. The system accepts this and I can ssh from one machine to the other. Both NFS client and server start w/o issue and the client mounts the device just fine. But when I try to copy a file on the NFS client from the local disk to the server, the client just hangs and I have to physically turn the machine off in order to get it to work. Both systems are using the stock software from the DVD (I didn't update either).

Oct 18, 2010I am looking for a PCI Ethernet adapter which supports jumbo frames. The card I have now - Trendnet TEG_PCITXR - says it supports jumbo frames but it turns out the MTU is 7200 bytes. Yeah this is more than 1500, but it seems like a bit of a scam to me. Since it is nearly impossible to find these specs on product info pages, I was hoping someone could recommend a network card that is proven to support 9000 (or greater) MTU. Some more info, I am running Ubuntu 9.04, kernel 2.6.28-19

May 13, 2011How do you set the MTU on the network card for Jumbo Frames? The MTU drop drown only goes to 1500 which is far from the Jumbo frame rate of 9000. If I type 9000 in will it blow anything up?

Ubuntu Multimedia :: Export Video Frames / Edit And Return Frames To Stream?
Oct 16, 2010I'd like to edit a few frames from some videos, and then return them to the video stream for playback. What are the best tools to do this with?
I tried exporting a frame with Kino, editing with GIMP, and then re-inserting it into Kino, but Kino rejected the attempt.
Will Kino do this, or do I need to be using something else?
General :: How To Change X-Windows Default Border Width For All Window Frames In Ubuntu
Jun 14, 2010Way back from Windows 3.x days to the latest 64bit Windows 7 (classic/standard theme)there is a way to make the window edge border wider then 1 pixel.I often use 3 to 5 pixel to make it easy to grab on hi-resolutions displays and hi DPI monitors.There doesn't seem to be an easy or obvious way to do this with the Gnome X-Windowing system?
View 3 Replies View RelatedUbuntu :: Movies' Frames Don't Refresh
Sep 1, 2011I am experiencing a problem with viewing 1080p movies. The frames get stuck and don't refresh, so I am left with a single image while the sound plays on fine. I find that this only occurs with high resolution movies, but I am curious as to where the problem lies and if I can fix this at all. Here are my computer's specs and configurations:
I am using Ubuntu 10.10 (didn't want to get 11.04) with 2GB or ram and 972.6MB of swap (I need to increase that to 4GB, I think? Correct me if I am wrong). I am using a Toshiba u400 Satellite which comes with a Intel X3100 Integrated Graphics chipset (don't really know the strength of this set up) and has two 1.73 GHz processors. The only thing that is within my power to change is the swap allocation. When I start the movie and bring up the System Monitor, VLC takes up almost the entire CPU usage.
Software :: Mplayer Frames Per Second Not Working?
Jun 19, 2010Since I installed Ubuntu 9.10 recently and downloaded a new copy of MPlayer, a Shell execution of Mplayer of a video with the -fps switch, sees the -fps being ignored. The video in question plays the video too fast and goes out of synch with the audio. This has never been a problem as I play the video using the shell and include the -fps option to slow the video down. For instance, the command below would play the video at 30 fps:
mplayer -x 640 -y 480 -fps 30 "/media/USB2/williams.flv"
It has always worked before. What's changed in the latest mplayer, or is there something else I need to install in order to get -fps functionality? I can paste the (rather long) output mplayer gives upon execution of the above command.
Ubuntu Installation :: Frames And Buttons Gone After Update?
Aug 10, 2010Why would the frames and buttons disappear after a regular update. I rebooted which took back the buttons I was missing from the top=right corner of the windows but, the frames are still missing? I am using a combination of Compiz and Metacity and until now all has been working really well. I don't even have the awful window resize delay I was having.

It doesn't make any difference. Now I am running meta-city and emerald without any desktop effects.
View 2 Replies View RelatedProgramming :: Injecting Raw Ethernet Frames Using TAP Interface?
Apr 26, 2010I have UDP packets generated on Machine A that are addressed to Machine B (unicast) that I capture with PCAP. After transporting this raw data to Machine B (via RF modem) I'm trying to reinject the original UDP on Machine B through a tap0 interface. The capture and transport are all working fine. BUT once on the destination machine, the reinjected ethernet packets are NOT being received by a local UDP server. this is my socket creation :
Code:
outputSocket = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
struct ifreq s_ifr;
strcpy(s_ifr.ifr_name, "tap0");
"data" is an unsigned char array that contains the original packet data received from pcap, which includes the ethernet header, ip header, udp header, and payload data. after the call to write() completes, Wireshark on Machine B sees a correctly formatted (checksums and all) UDP packet when listening to tap0 - ie. no lines highlighted in red. *BUT* - a UDP server i have running on Machine B never receives the reinjected UDP datagram. (I have verified that this server works, by using a simple local udp generator app.) is there something wrong with how I'm creating the socket and/or writing the data back out to the tap0?
Debian :: Iceweasel - Frames Not Drawn Properly On Webpages

Ubuntu Multimedia :: Mini-lag When Viewing Video Looks Like It's A Few Frames Too Little Per Sec
May 3, 2011I have Ubuntu 11.04 on a Dell Studio XPS 1640 with ATI graphics and the fglrx driver. It's a powerful machine and I've had no problem what so ever to watch full hd videos on windows 7 but all videos, no matter the resolution, has a very small stutter which is annoying but not making the videos unviewable. But I'd prefer not having it at all. I have tried setting the VLC video output to x11 but there is no difference. It's a screen tearing problem, that was fixed by setting the option "Tear Free" on in ATI Catalyst Control Center.
View 2 Replies View RelatedNetworking :: Sending Frames Of Size 1518 Using Raw Sockets
Aug 19, 2010I wrote an application that receives packets on one interface and sends them to another interface after it added a vlan header. Both the sending and the receiving is done using raw sockets. Everything seems to work fine until I get TCP packets that are of size 1514 (MTU). Once I add a vlan header to the packet, its size becomes 1518 and when I try to send it I get the returned value -1 and errno=90 (message too long). I tried to change the MTU of the NIC to a value that is bigger than 1500 but that fails. If I create a bridge using brctl and vconfig between the NICs I can see that my NIC does sends packets of size 1518. What do I need to in order to make my NIC to send packets of size 1518?
View 5 Replies View RelatedSoftware :: Saving OpenOffice.org WP Frames In Word Docs
Jul 14, 2010In my graduate professional writing program, I have had to make several documents that integrate graphics. In order to manage the graphics, I taught myself how to use frames. But I discovered that the Openoffice.org word processor has a problem saving the frames correctly. I save my document and close it. When I reopen it later, the graphics in some of the frames (not all) are distorted; they appear cut in half. Examining the frames, I determined that the anchors of the affected frames had changed since I saved and closed. Changing the anchors back to whatever they were restored the graphics to normal. Every time I saved and closed, this happened again. The first solution I came up with was to save with the frames set properly, and export the document as a PDF file; the frame anchor settings will not mess up for that.
Then, because I save my school documents as Word files (the university--that program, anyway--doesn't use Linux), I tried saving the document as an OpenOffice text document (.odt). That also avoided the frame anchor settings problem, meaning the problem occurs only when saving as a Word document. But since my professors probably don't use OpenOffice, I am submitting PDF documents in this situation.

View 3 Replies View RelatedGeneral :: Ubuntu: Tool For Displaying Disk Activity In General And By Process?
Oct 12, 2010My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

General :: Samba File Permissions For Multiple Groups In The Same General Path?
Nov 4, 2009I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

Jun 6, 2011II'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.
