General :: Multiple Nic Cards Rhel5 Cannot Be Access Simultaneously?
Dec 18, 2010
I installed 2 nic cards in my pentium 4 computer running rhel5 to be used as a proxy server and connect 2 computers in each network card for testing . The problem is I cannot ping or use the 2 cards simultaneously . One must be deactivated for the other to be ping . The Network configuration panel indicate both card status as active but i can only ping the first to be activated . I have already set onboot=yes to both cards but still the same result after restarting . The nic cards are onboard - Realtek RTL8139 and pci -3com 3c905b.
Performing commands in multiple subdirectories simultaneously. I'd like to run a program I've copied into every subdirectory which takes *.in files in the current directory as input files. I can find the program, but how do I tell it to run when I've found it?
i'd like to execute in several subdirectories that all have the same name, but I don't want to have to change into each subdirectory (there are hundreds) to execute the script. All the subdirectories have the same name ("final_alignments"), but are located in parent directories with different names. All these parent directories are in the same "super parent" directory. I've tried to do this using "for/do" and "find" but no luck so far.
I have onboard video card (GeForce 6150SE nForce 430) and I install one PCI-E video card (GeForce 7300 GT). In BIOS I set primary video cart to onboard. Is it possible to work simultaneously? lspci -v command showing both, but nvida-setting, nvidia-xconfig and system-config-display only show one, never both.
I am looking for software (Windows or Linux) that can do the following: Resize one image to several provided sizes. Detects the type of the picture (wide, normal) and does the resize based on that. What I mean by that is that it should not break the image by shrinking it more in one direction then in the other so it looks weird. The purpose of this is my Blog. If I want to give my readers a wallpaper, I want to give them several options for the sizes so they can have it in their own preferred screen resolution. The image must however keep its original aspect ratio.
I have 2 ATI cards that I used to use on windows to run 4 monitors. A recurring problem has been to get them detected in linux. Only my secondary card is picked up linux. When I manage the displays it detects the 2 monitors connected that card.
What are the specific steps I should take to get the second card detected? Supposedly there is a tool system-config-xfree. I don't have it, yum can't find it.
Also I heard it has something to do with editing some xorg.conf file or something to that effect. I have absolutely no idea how to find the "bus id" of my card, or lookup the horizontal refresh rates, etc..
I would probably have no problem following the documentation & editing the file if I knew a good way to find these values.
Someone also suggested installing linux twice and saving the xorg.conf it generates each time (with different card each time) and then merging the two by hand. That is like killing a fly with a hammer though, when I do this again and again in the future It'd be nice to not have to take twice as long.
In Ubuntu Lucid Lynx RC, I got NVidia's TwinView to work with 2 monitors in a single video card. But when I use the same monitors but split them between the video cards I can't make TwinView work and it starts a X server for each monitor. I want the same effect I had with one video card.
If I have only 1 physical WLAN interface, is there some hackery that can be done so that it can be a client of an existing access point and at the same time also act as an access point for other clients? I have an existing 802.11g ADSL router, and I'm going to be building an HTPC which will have 802.11n. My laptop also has 802.11n, but at the moment it only connects at 54Mbps because thats what the AP supports. I'd like to be able to have the HTPC be a client of my ADSL router, but have my laptop be a client of the HTPC, so copying files to it will be faster.
I recently purchased a set of three professional mics and converters for them (they are XLR mics, so i bought three icicles to convert into the USB port)The computer sees all three microphones, but I can figure out how to be able to record on all three at the same time.Is this at all possible, or did I just waste a ton of money on converters?EDIT: I would like to add that these mics are identical, and I'm wondering if nothing else if it's possible to merge the two mount points so that it appears as one micEDIT AGAIN: I have also just installed Pulse Audio Volume Control, and it picks up both mics. How can i tell audacity to use this?
I have been working on a project for a while now that involves a rather complex daemon that has to be simultaneously running different tasks. For example one of these tasks is to receive IP packets from the Netfilter queue and place those packets into one of several internal queues. While other tasks involve taking IP packets from those internal queues and processing/manipulating them and finally returning them back to the Linux network stack.
As I as I have no previous C experience before starting this project I just spawned a new thread each time I needed the daemon to be doing something else while those other tasks continued to run. Is there any other way of doing this or is this pretty much the only way of doing this? Because C is procedural I could not figure out any other way of doing accomplishing what I wanted. Should I have done it some other way or is this the correct and only way I could have gotten my C app to be running multiple tasks at the same time?
I'm trying to write a bash script that will simultaneously ping a host and execute a traceroute at the same time. I would like the results to output to a text file.
I have a list of approximately 50 words that I'd like to search documents for and delete those words. I was wondering if there is some type of automated process for removing multiple words rather than me manually putting each word into 'find and replace'
On that note I guess I could write the Macro in python if there isn't anything out there that does this. However I read that open office only works with python 2.3.5 or something of that nature, and I have already installed 3.1. Is that still going to be an issue?
Here's the setup: One x86 server (Red Hat 4) with two serial connections to an embedded linux device. One serial connection is to a power control so the device can the restarted, and the other is used for a console to this device. Both serial connections use minicom. People on my team VNC to the x86 server, where they find the two minicom sessions waiting for them as they are left open. I would like to automate connecting to the server and communicating over the serial lines.
Supposing I use ssh to the x86 server, could minicom be used over the serial lines without terminating the minicom processes seen through VNC? If not, is there a way to re-open those windows from within the ssh session, so a user who VNCs to the server won't have to reopen them? Could a single ssh connection control two minicom terminals simultaneously, or would there need to be two ssh connections? It is assumed a user and the automated process will *not* try to access the device at the same time; the automation would trigger during off hours.
i want to copy one or more files or directory from one drive to multiple drive simultaneously. It like a cloning a disk. But i dont like clone entire disk. i want to copy/clone only certine files or folder. if any one can know how to copy one source to multiple destination simultaneously.
I am interested in sharing an external drive between two computers. I do not want to disconnect the drive from one and then connect it on the other one - I want to share it.
Would this work with an external USB drive and a normal USB hub? Or is it something more complicated/impossible?
Also connecting the machines via network is not possible - it has to be USB, or I can connect it to one machine also via Ethernet but the second connection has to be USB.

RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03) 04:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3600 Series Initially I had just teh HD 3600 in the PC, using the "AMDccle" drivers and configuration running two monitors.
I then added an old RV280 PCI card to allow a third monitor. When the PC powers on the bios output is on the RV280, once linux starts the RV280 monitor goes to the ubuntu desktop colour, the two monitors on the HD3600 get a signal (power up) and display the logon screen.
When I log on the two HD3600 screens become my desktop. If I ctrl alt f1 etc. the terminal screen comes up on the RV280 and the two HD3600 screens go blank. This suggests that all 3 monitors/ 2 graphics cards are all working ok, and ubuntu is happy with them. My problem now is to make the RV280 accessable via X/gnome at the same time as the HD3600. It would be nice to have it as a 3rd monitor on a very wide desktop, but I'd settle for it being its own little window running various tasks/programs such as mail/firefox.
Is it possible to output one playback stream to multiple devices simultaneously with the current PulseAudio / Phonon setup? The PulseAudio mixer only has radio buttons to choose one device per playback stream. I believe the hardware is capable of this, since I remember doing that before we had PulseAudio. How can I duplicate an audio stream?
Here's one application scenario: I am travelling with my family, all crammed in small hotel room. My wife and me want to watch a movie on my laptop without waking up our kids. I just happen to have one analogue headphone available and one wireless USB headset with me. (Of course, the low tech solution is to bring an 3,5mm Y-cable to attach two analogue headsets, but I would really love to use the USB headset together with the analogue one.)
Another similar thing that bugs me is that my laptop's built-in speakers now always seem dead when an analogue headphone is plugged in. This is mostly what one wants, and before PulseAudio, one had to manually switch them off which was generally annoying. However, the downside is for example with notifications.
For example, before PulseAudio, I could configure Skype to always ring over the laptop's built-in speakers, regardless of whether the analogue headphones were plugged in. This is no longer possible, since PulseAudio does not distinguish between built-in speakers and built-in analogue port any more, while old Alsa did. So in my office, where some analogue headphones are plugged into the docking station, I never hear Skype ringing if I don't wear the headphones.
I need to implement at my sister this kind of connection: She is connected on Local area network that has about 50-80 pc's, but for internet access she must start an pppoe connection. For now when she wants to use lan she must put her local address (ps: they dont have dhcp), for pppoe she uses dhcp. Problem is that on that way she can't access lan and internet at the same time. She must disconnect from lan and then start pppoe connection and vice versa. I'm intrested if it is possible to have lan access at the same time as internet access. some kind of tunel through lan up to isp. I was googling little and so PPPoE tunneling. Is it that what I need here?
I've been using linux for roughly 12 years now but I've always avoided linux on the desktop since touching X back in the day was quite a hassle. I recently decided that rather than keeping my windows desktop full of 15 PuTTY instances, I should rock the *nix desktop.
I started by installing Ubuntu 10.10 Desktop. It detected my two monitors handing off a pci express card just fine. I decided to install the ATI drivers when it prompted me - the proprietary drivers would let me select to use the monitors separately, but would always just default back to mirroring the screens. I was unable to get it to stop that, so I had to go back to the open source drivers. Which is fine, I don't really need the 3d accel. Roll forward a week, I ordered another video card to add another screen. I purchased another ATI card, since word on the street is that same-vendor chipsets play best together. This one had to be PCI, if this matters.
dmesg reports the new card is fine and happy, but the Monitors GUI thing doesn't detect any monitors off the new card, or report anything about it. So: what should I do to make the second video card get noticed?[URL]...
I've been struggling trying to get a Lenovo T410 to display video on both it's internal LCD and an external display at the same time, and I need to get it working by Monday or I'm toast. know this will work with other distros, but we are contractually bound to use RHEL5.If we use the laptop on it's own there is no problem, however once we set it in the docking station, the external display shows no video, unless it is rebooted. Then it will only display video on the external and not the laptops own display.
Our engineers are constantly going to meetings and need to be able to undock the laptop and have the display appear without having to reboot. Then conversely, return to their desks and have the video on the external display without rebooting.I suspect that the problem is that RHEL5 is only up to release X11R7.1 of X.Org, which is still using version 1.1 of RandR and from what I can surmise, 1.1 of RandR does not recognize multiple video outputs.I was hoping that someone more knowledgeablthan I can confirm this and if I'm right do I need to manually build the latest release of X.Org to get this to work
I have 2 NVidia graphics cards, a GTX275 and a GT210. My system boots just fine in 32-bit Windows 7, so I know it isn't a hardware problem.Linux boots fine with either the GTX275 or the GT210 installed, but hangs after the file system check if both are installed. My motherboard has 3 pci-e slots, an x1, x4, and an x16. I've tried various configurations, all fail except 1 graphics card installed in either of these slots. I got my system to boot a couple of times with both cards installed in Xbuntu 9.10. Then this problem randomly happened.

I'm not inclined to believe the problem is here. I don't even get a bootsplash, let alone XServer to start. The system hangs after a flurry of HDD activity. Checked partition, and it's ok.

I have an M-Audio Delta 44 sound card, and a USB MIDIinterface device, both are recognized, and work. My problem is as each are seen by alsa as sound cards, sometimes the alsa card numbers switch between boots. Is there a way to set these devices to always have the same card number for alsa
I'm having problems getting two wlan cards to work under Networkmanager with F12. I have an old server that I wanted to move, so thought I'd get a USB wlan device for it. before setting up the server, I thought I'd try the USB (an Edimax EW-7711USn - Ralink 2870) on my laptop first. My laptop has an inbuilt ipw2200 card that works fine under NM.
So I've down loaded the DPO_RT3370_LinuxSTA_V2.4.0.1_20100831.tgz file from Ralink, and built the driver (after changing the os/linux/config.mk file for the WPA supplicant settings). I also install the rt2870 firmware (from Ralink) in the /lib/firmware directory. I also blacklisted the rt2800usb driver to ensure that that didn't get loaded.
The problem I have is that I can now get both the ipw2200 device and the rt2870 devices 'working', but they both try to assume the same IP (I want fixed IP's and not DHCP for them) - what is the way to configure the 'devices' so that the rt2870 device is always given IP x and the ipw2200 given IP y?
I think my problem is really my lack of understanding where/how NM handles the files under the GUI config. I used to semi understand how the old network config tool set up it's files and where they were etc. But with NM I'm a bit lost as to how it equates the device with the network settings. Once I have the device working with the correct driver on my laptop, I'll look to apply the same settings on the server (which is then FC13 - but should be simpler as it doesn't have an existing wlan interface).
I'm running ubuntu lucid and i was thinking in purchasing one or more extra wifi cards to try to configure my computer to manage different conections at the same time, with different isp's. The thing is that I'm not quite sure if what i want to do is actually possible.
The easiest way that crossed my mind was to try to configure a / multiple virtual machines that are redirected threw proxies to ubuntu and try to configure that each proxie port goes threw a different internet gateaway. This way i might be able to divide threw different sessions of JDownloader, installed on each virtual machine, the things i want to download. The negative aspect of this idea is having multiple jdownloader sessions will make my laptop work to almost 100% for sure...
Another thought i have was to make JDownloader manage its downloads in only one session redirecting them to my internet conections; the negative thing is that i think i will have to try to modify its source and learn java...
And well my last possible configuration i had in mind was to try to make ubuntu directly add up all my internet conections manage as if it was one. the negative thing here is that i might not be able to get multiple downloads from some sites
Well, all this where just thoughts, im struggling whether to buy another card or not to try to setup any of this configurations but im not really sure if any of them are actually possible. Is there an easy way to manage this?
I just want to take the most out of my internet conections... if i'm at college i have to options that are quite slow, adding them up with two cards would be great, i might also be able to add a third and a fourth conection. Also if i'm on a coffe and i need some bandwith i could try to make it go with an open network arround, etc.
I'm about to start a new build for my primary machine at home. The plan is to load up a server/workstation motherboard (ASUS KGPE-D16) with two 8-core chip, as much RAM as it will take (32GB) and to put two graphics cards in it. One to power my main 24" monitor (ideally via HDMI) and the other card to power two screens, one 24" on each left and right side via DVI (unless I can find a dual-HDMI card that meets my needs).
Does that make sense? Here's my question for this awesome group of intelligent individuals: What video card model should I choose? Obviously, I'd like them to match so I can SLI / CrossFire if I really want to, but what setup should I plan on to have a good experience managing multiple displays on multiple video cards?
Oh, and budget is probably up to about $300 per card, maybe a little more if it makes a lot of sense.I'm not alone in having tons of problems with trying to get multi monitor support in the last few versions of Ubuntu, and honestly it's the only reason why I'm still running Windows7: the multi monitor support is just SO DAMNED easy! I shouldn't have to spend this much energy thinking about video card model- it should just work, shouldn't it?
I'm wondering a couple of things about my LAMP stacks:
1) How do I get a list of all the network cards installed in a linux box? I've run this command and it shows 2 network cards which is probably all of them: Code: mii-tool -v
2) How can I check the percent utilization of a given network card? I.e., at any given time, what linux command will tell me the how much of a network card's bandwidth is being consumed? I've checked both ethtool and mii-tool and I don't really see any helpful stats.
3) How can I make sure that a linux box will optimally use both network cards? I'm a bit fuzzy on how IP addresses and network cards and hostnames work together.
I've got two network card interfaces on my computer, one wireless and one wired. The wireless card is connected to the Internet and the wired is connected to the LAN. When only the wireless card is active, Internet works. As soon as i enable the second wired card, Internet stops working. And it seems like Ubuntu chooses the wired card for Internet as soon as it's enabled.
Are there any ways to solve this? So my Ubuntu box always chooses the wireless card for Internet traffic and let me use the wired device for LAN only?
I installed 4 encrypted partitions (/, /var, /tmp, and swap) that are mounted at boot using the Alternate Installation Disc, and they all have the same password, but I have to type that password in 4 times when booting up. How do I make it so I only need to type in my password once?
