Ubuntu Networking :: Adding New Network Card

Apr 17, 2010

I've switched to a new motherboard, an Asus P6T SE one, and now I don't have any cable connections in Networkmanager anymore.

I see the new card when I run "ifconfig", it's called "eth2", but I have no idea where to go from here without messing up networkmanager.

General :: Adding A Network Card?

Mar 5, 2010

I'd like to add another network card to my linux box. I've plugged in the hardware and rebooted, but I do not see a second network config file under network-scripts. Also, if I hit ifconfig -a, I only see one network listing. How do I proceed?

Ubuntu Networking :: Adding Network Printers To Server 9.10?

Mar 1, 2010

I have Ubuntu Server 9.10 up and running as my file server. However, it sits amongst other PCs running XP Pro and Network Printers (e.g. Xerox Docuprint C2535A) on the network. My question is whether there is a way of adding the Xerox printer to the Ubuntu Server so that other PCs will send print jobs through the server. I think the printer is windows-based printer. Is it possible to do this? or are there any other options that you may be able to share with me?

Fedora Networking :: Adding Another Network To Routes And Shorewall?

May 10, 2011

First I will give some background. We have a currently working network that the Previous network Admin assigned an internal IP scheme of 200.1.1.0/24. I have no idea why he would have done such a thing, but it is my job to fix it (and keep our systems up and running). We have a Fedora 10 box on the 200 network that is acting as a router and a firewall (shorewall to be exact).

I added another NIC card (thank you again to all the great people on this forum for helping me get that working) and it is eth2. Assigned it a 10.100.1.A/24 (This is just a variable for the real IP). The other end of the cable that I plugged into that NIC connects to a Cisco Layer 3 switch. I assigned the port that connects to the other end of the cable the IP address of 10.100.1.B/24

Ok, I added the static route of ˜ip route add 10.100.1.0/24 via 10.100.1.A dev eth2' I added loc2 (which is my eth2 adapter) to the /etc/shorewall/zones file. I set eth2 on loc2 in the /etc/shorewall/interfaces file. loc2 eth2 detect I set the lines in the /etc/shorewall/policies file loc loc2 ACCEPT info loc2 loc ACCEPT info I can ping the cisco switch from the linux server itself. From a PC on the original network I can ping the new NIC card in the linux server, but cannot ping the cisco switch, so I figure it has to be either the route or shorewall.

Networking :: Adding Route To Dedicated Network Behind Gateway

Mar 23, 2011

My workstation is on a network, let's say 10.100.0.0/24. I'm opening up an openVPN Tunnel to a test environment in my company, receiving a lot of routes to this network (address range 172.xx.yy.0). Everything is working fine so far. In this test environment I placed a number of virtual systems having their own private network (10.99.0.0/24). I have one machine in this virtual cluster which is able to forward incoming IP traffic to the others.

When I login to this gateway system, using the 172.xx.yy.zz address, I can logon to the others using the 10.99.aa.bb addresses. Fine so far. But I have to be able to call these machines with the 10.99.0.0/24 addresses from my laptop. So I tried to add a route like:
route add -net 10.99.0.0 netmask 255.255.255.0 gw 172.xx.yy.zz

Unfortunately I received an error messages:
SIOCADDRT: No such process

According to the entries in other forum articles (Google helps in most cases), I have to add a host route first:
route add -host 172.xx.yy.zz gw 172.well.defined.dest

Networking :: Adding Wireless Router To An Existing Network

Dec 22, 2010

I have an existing network that connects to the 'net via a Linux-based firewall. That system has two ethernet interfaces: one to the DSL modem and the other to the internal switch. Future plans were for adding a second "internal" interface with the idea of moving servers into that (think DMZ). But while I was planning for that, the missus has decided she wants to pick up a Windows laptop and would like to be able to use it wirelessly at home. I have access to a (free!) Netgear WGR614L and was hoping it would work. Unfortunately, I'm unsure how to add the wireless capability to our network.

Questions:

Is it best -- or even possible -- to use one the wireless router for this?

Is it possible to merely hang the Netgear router off the internal switch and set it up for the wireless users? Or...

Would I need to add another ethernet interface to the firewall and hang the router off that? The address of this new interface would act as the default route for the wireless users. Then I'd need to (I assume) add more rules to the iptables configuration to deal with the new network. (I sort of like this option -- it it's actually feasible -- as I can easily shut down any wireless access by logging into the firewall and stopping the interface connecting the wireless router.)

I've taken a look at the setup guide on the CD that came with the router and it assumes that you have a modem connecting your PC to the internet. The instructions have you placing the wireless router between the modem and that PC. For our network, that would have the wireless access coming into the "dirty" side of the firewall. (Not what I would like.)

Ubuntu Networking :: Wireless Home Network Is Not Recognized By Network Card (RealTek RTL8190 Mini PCI)

Jul 12, 2010

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.

Ubuntu Networking :: Broadcom Corporation NetXtreme BCM5721 Network Card Randomly The Network Connection On The Server Will Stop Working?

Jan 29, 2011

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?

Ubuntu Networking :: Network Card Not Detected?

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 :

Ubuntu Networking :: Network Card Not Detected

Jun 16, 2010

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.

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.

Ubuntu Networking :: Network Card Not Working / Get That?

Apr 21, 2011

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.

Ubuntu Networking :: Need Static Ip On Wireless Network Card

Mar 15, 2010

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.

Ubuntu Networking :: Intel Network Card Up/Down On Current 10.04?

May 18, 2010

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?
