Ubuntu Networking :: Set Up Dual Lan Card Within Same Network?
Jun 18, 2010
how to set up dual lan card using different ip addresses within the same network? for instance, i want eth0 to be 192.168.0.100 and eth1 to be 192.168.0.200 so that the bandwidth of each card could not be saturated easily. both lan card will be using the same gateway and dns which is 192.168.0.1. the eth0 could be used for mysql connection, while the eth1 could be used for samba connection for the entire network of 192.168.0.0/24.
is this possible?? i've tried but to my bad luck, it didn't work quite well, especially the connection to the internet.
my wireless home network is not recognized by my network card (RealTek RTL8190 mini PCI). The post was as follows: "I am using a new computer with Windows 7 , Athlon quad core 2.60 64 bit, 8GB RAM. Internet conection works fine with ethernet but ubuntu does not see my wireless network. card (RealTek RTL 8190 ID: 10ec:8190). Have searched this forum but unable to come up with a fix. I was looking for windows XP drivers to use Ndiswrapper but could not find a list of .inf files. My network is OK and works perfectly in windows and with my 2 laptops. Can anyone point me in the right direction? Additional info: install was done within Windows using WUBI to a separate partition on my HDD. I am new to this and thouroughly confused as to the procedure for installing the drivers if they are in fact available."
I am very frustrated in that I would like to use Ubuntu 10.04 but it is useless without internet connectability. I am new to linux and do not understand where to get the appropriate drivers or how to install them. I wish someone would answer this post and either give me a clue what to do or just say "give up" and uninstall ubunutu.
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
Cannot activate network device eth0!"device eth0 does not seem to be present, delaying initialization".i cannot find my network card while i set up network configuration Now I use dual boot window 7 and fedora 9,I cannot find my network card in select network adapter while network configuration ,i have a network card Atheros AR8132 PCI-E fast Ethernet controller NDIS(620)and for wired in Accer laptop .
I have bought a new laptop with W7 installed. And I installed dual boot with Ubuntu 9.10 on it.I tried to connect my laptop to Internet by Ethernet port. It works with W7, but Ubuntu doesn't detect my Network card .After some research on Internet, I suppose that it's a problem of drivers for this card.Here some parameters I could get :
>ifconfig : lo Link encap:Boucle locale inet adr:127.0.0.1 Masque:255.0.0.0
I'm in serious need of some help. The network adapter on the motherboard of my main machine apparently failed about noon today. This machine serves as the firewall and router for my home office LAN, and so it has two network adapters, the second being a PCI card installed in the only PCI slot of the mobo. The mobo's adapter served the WAN while the PCI card serves the LAN.Since the mobo has only one PCI slot, none of the other PCI cards I have on hand could be used. Instead, I pulled an unused PCI-e dialup modem card from the machine, and bought a PCI express gigabit card to put in its place.
The problem is that the machine (running Hardy 8.04.4 LTS) does not recognize the new card at all. Running lspci shows only the old PCI card that serves the LAN. Similarly, running "sudo lshw" shows only the old PCI card together with a virtual adapter that's part of my VirtualBox installation on that system.I then dual-booted into Vista Home and attempted to install the new card there, using the CD that came with it. Vista detected the card and asked for the disk, but then was unable to find any drivers on the disk!The box says the card is from Star Tech, and the instruction sheet says its model is ST1000SPEX.If anyone can point me to the correct module to add to the startup list and/or remove from the blacklist, that may get me going again.
Hi, So brand new to Ubuntu and linux for that matter. Can't seem to get my network card up and running I have tried the various fixes through the forums, as you can see in the screenshots. Just hoping an expert could help me out so I can finally close the box and get sleep. I have a ASUS M4A78T-E with phenom II. I downloaded ndiswrapper (1.9) and have wicd. The card is trendnet 643PI but it shows up as RealTek 8190.
I have BroadCom BCM4318 802.11B/G Wireless Card. When I first started Ubuntu a week ago it didn't work, but I fixed it after a day or two of googling it. However I made a mistake and uninstalled the Network Manager. I then reinstalled Ubuntu, but it wouldn't load the card again. I activated the driver, and restarted the computer, but then, since It was connected via Ethernet, it wouldn't reconize the Ethernet connection, but the wireless card it did, but wouldn't find a network that is supported.
I have a headless machine set up on my LAN which is dual boot, Ubuntu 10.04 SE and Windows. I have a printer attached to it. (HP Deskjet D1500 series) I also have a shared folder located on the machine.
Through SMB I've been able to recreate the share in Ubuntu to point to the share on Windows. When the machine is in either OS, the share can be resolved, browsed, edited, etc, from \hostsharename. Through SMB I've also been able to share a printer attached to the machine (and print to it). I have a problem though:
When the machine is in either OS, it is possible to use the same scheme to access the shared directory. This is not true with the printer. When in Windows: My Windows 7 x64 machine can connect to the printer, look for drivers, and when it doesn't find drivers in \hostprint$, it uses its own. My W7x64 machine can print a test page, and any other pages for that matter. My W7x64 machine lists the printer as "HP Deskjet D1500 series" I do not have to re-add the printer.
When in Ubuntu:I have to re-add the printer to my W7x64 machine. I have to specify the driver to use, regardless of whether I use the same print$ directory. Re-adding the printer gives me a network printer by the name of the printer, not the description (e.g. "HP Deskjet D1500 series")
My goal is to mimic the transparency of the shared directory, so whereas I've created a shared directory in Windows that persists between OSs, I want to create the network printer to persist across OSs. I can print to the printer in either OS, but the "printer" I have when the dual boot machine is in Ubuntu is NOT the "printer" I have when it's in Windows.
I need to accomplish this to avoid booting the machine into Windows for a client to print something. It seems very odd that I can make Apache, PHP, MySQL, shares, and common files persist/be identical between OSs, but not network printers. I've worked this for a few days now, exhausting what I can in information on SMB and CUPS to no avail. I am exhausted myself.
I am running ubuntu server x64 as a router. I currently have 2 LAN cards, eth0 and eth1. and I want to add wireless capabilites to the machine.I was wondering if any of you know which card I could use?I want it to be supported in ubuntu server and it must be n-draft, as it is to replace a Edimax n-draft router.
I want my Ubuntu desktop to have a static ip-address, i have altered the interfaces file to the below and also filled the info regarding my wireless network card but still every time I reboot the desktop gets the ip 10.42.43.1, HOW is that possible???
I use a apple time capsule router, I want my desktop to run a apache server thats why I need the static ip. I also want the static ip to be set on the wireless network interface. I have an old laptop with an internal Intel pro 2200 card so there should not be a driver problem.
This i my interfaces config code...
To be on the sure side to get this to work I have configured my router(DHCP) to give my wireless-HWaddress the ip of 10.0.1.15, STILL the ubuntu desktop starts with the false address above.
Recently I hibernated my computer, then when starting up again managed to boot into Windows instead. When I rebooted back into Ubuntu 10.04 my network card had stopped connecting to the internet.'s not a problem with my connection -- I'm posting this form Windows just fine. Using the network tools tool I can see that the card is inactive.I can use ifconfog to reactivate it, but it still won't connect.Attached is as many commands as I could find that provide information about the card
I am running Lucid Lynx and have only noticed this problem in the past couple weeks. Before Lucid I ran Jaunty & Karmic on this same box, although I installed Lucid as a clean install. My problem is that up to 5 or 6 times per minute my networking card drops its connection and then has its connection re-established. I have an integrated Intel 82566DC gigabit card on an Intel Motherboard DG35EC connected to a 10/100 network and am running the 64-bit version of Lucid. I've done some considerable searching on this problem and although I've seen many references to similar problems dating back several years, I have found none that seem to have any solutions that do anything for me. I never had this problem under any prior version of Linux on this box (all prior versions were also 64-bit).
In short, this block of messages repeats in my messages log:
May 18 20:18:50 mark-desktop kernel: [10121.062129] e1000e: eth0 NIC Link is Down May 18 20:18:52 mark-desktop kernel: [10122.730873] e1000e: eth0 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX May 18 20:18:52 mark-desktop kernel: [10122.730876] 0000:00:19.0: eth0: 10/100 speed: disabling TSO
Most of the time I don't even see that the connection has gone down. Sonetimes everything seems to be operating fine for a half-hour or more, although it could be dropping out and coming back really quickly all of the time. Sometimes it goes out for 10 seconds.Sometimes it goes out for many minutes and I can get networking back by killing disabling networking and then re-enabling it. It's quite annoying.
I'm sorry if I'm duplicating an existing issue on this forum, but I can't find this exact problem anywhere. Does anyone have any clever ideas about how to fix this?
I installed ubuntu netbook remix (the new version 10),and when I try to install drivers for my network card it says I need an internet connection,when I cant access the internet,I even tried using a wired connection (since I usually connect via wireless),but still its no use. My netbook is the following: [URL]...
The graphical option through the hardware drivers list 2 options, broadcom b43 wireless driver and the broadcom sta wireless driver None can be activated
The b43 displays: Sorry, installation of this driver failed.
Please have a look at the log file for details: /var/log/jockey.log
I have a Realtek gigabit onboard ethernet (RTL-8110SC/8169SC)It was working in 9.10.After upgrading to 10.04, the connection dropped to 10MB. Now, lspci -v shows the card, but Ubuntu no longer recognizes eth0!I have no connection on the machine. I've been digging around the forums, but can't seem to find what I need.
I'm trying to configure my network card using the b43 driver. I'm running 10.04.2 on the kernel version 2.6.35-25-generic-pae.
Surprisingly, I was able to connect to my home wireless network using the b43 driver without a problem. The only issue is that it doesn't automatically connect. I have to use the following command in order to get it to work:
Code:
After typing my password, I wait for 10 seconds and am automatically connected. My question is, how do I configure my system to do this for me permanently (or at least automatically) so I don't have to type it every time I log on?
So I want to run a Minecraft Server on my computer running Ubuntu 11.04. My goal is to have the server running over my network through one of the virtual terminals without any type of GUI running (to conserve resources). I'm shutting down the ubuntu GUI using the command:
Code: sudo service gdm stop which does a great job, but it also kills my wireless connection.I've tried editing my /etc/network/interfaces, and even uninstalling the gnome network mananger, but nothing seems to work. Can anybody help?
I added to my machine PC running debian and others, ubuntu, pc wireless card:,the same card I used it on other machine, it ran nice.On the other machine i have Ethernet Controller instead of Class ffff.I installed the divers firmware-ralink and other realtek and network-manager, but nothing.on other machine, that was enough to run it correctly.and ifconfig dosn't give wlan0,iwconfig did't give characteristic of wlan0.does this mean that the bios didn't recognize it as a network card
I run an Ubuntu Server in a Virtualbox environment. Setup works fine. In virtualbox, I accidentally hit a button that generates and assigns a new mac address for the network adapter. Since then the machine does not bring eth0 up. I tried the following ifconfig eth0 down; ifconfig eth0 hw ether macaddress; ifconfig eth0 up. Then restarted networking.
So I bought a used Dell Precision 390 Workstation and installed Ubuntu 9.04 on it. Everything seems to work fine, except for the built-in network card. Well, the graphics don't really work right, either, but I rather expected that, and I'll get to it later.
Anyway, when I boot Ubuntu and try to get on the internet, it says I'm not connected. When I open Network Tools, in the "Devices" tab, I get three Network device options: Loopback Interface, Ethernet Interface (eth0), and Unknown Interface (pan0). When I click on the ethernet device option, it shows me the hardware address of the interface, that it has multicast enabled, and that it is "Active", but I get no IP address.
Is there something really stupid that I'm missing? Do I need to do something special the first time I hook up an ethernet cable? I don't seem to remember having to do that on other Ubuntu boxes.
I have a 64 bit install of Ubuntu 10.04, I was surfing up to 11:30pm EST last night, shut down for the night, upon reboot am unable to connect to the internet or my local network. Ubuntu seems to think that I have no ethernet cables connected.My networking is controlled by my motherboard (Gigabyte P55A-UD4P) and the problem is not on my cable modems side. The modem has multiple wired jacks, all of them are unresponsive with my Ubuntu PC while my roommate can connect to all of them with his Windows 7 PC. Both network cables (the one connecting to his box and the one connecting to mine) are interchangeable: They both work on his and neither on mine, so there is no broken cable.I've followed the troubleshooting in other posts, here are some commonly requested diagnostics:
ifconfig -a Code: eth0 Link encap:Ethernet HWaddr 6c:f0:49:53:1f:c0
I have just installed Ubuntu 10.10 on a Dell Laptop. It has a Netgear WG511 (made in China) PCI wireless card but I cannot see any connections other than the wired one. Entering in lspci in the terminal mode and removing/replacing the WG511 shows (I think) that something is being detected in the PCI slot "Network Controller: Intersil Corporation ISL 3890 [Prism GT/Prism Duette]/ISL3886 [Prism Javelin/Prism Xbow] rev 01". Is this the WG511 and, if so, how do I get it to be detected as a network device?
I would like to change wireless mode on my network card. When i type in iwconfig in terminal so i get abg I would like to have only a mode active. How do i do?
got a new MoBo today. dropped it in and powered it up to find no network connection. when I dig though network manager I find no network devices, same with "network configuration" lspci gives:
03:00.0 Ethernet contoller [0200]: Atheros Communication Device [1969:1083] (rev c0)
ifconfig gives just the "lo" device. is there a hardware detection step I'm missing? I should mention this is a swap of one onboard NIC for another.
