Ubuntu Networking :: Bash Script To Find Network Device Connected?

Jan 17, 2011

I need a bash script to run ARPON for the connected network device, eth1 or eth2. (ethernet or wireless)

Arpon has an option (-o) to select the network automatically, but it only works for ethernet, hence i need this script. I've also tried running arpon for ethernet and wireless at the same time, but the arpon process running the inactive device will consume all of my CPU.

So, basically i need a script to find which device is connected, eth1 or eth2 and then to run arpon -d -i <device connected> (or something like that).

Is there an easy way to do this? code...

I've searched everywhere how to find the connected device via bash, but i couldn't find anything.

Ubuntu Networking :: VMWare Workstation 7 On 9.10 - Can't Find Ethernet Device

Aug 29, 2010

I just upgraded to VMWare workstation 7. I was previously running v.6, and an older linux version, and everything was working fine. I moved over the same VM files to the new computer, and it doesn't find the ethernet connection. When I start up the virtual machine, I get an error message:

Could not connect Ethernet0 to virtual network "/dev/vmnet8". More information can be found in the vmware.log file.

There log file doesn't say much more:

Jan 07 17:31:36.928: vcpu-0| VNET: MACVNetPortOpenDevice: Ethernet0: can't open vmnet device (No such device or address)
Jan 07 17:31:36.928: vcpu-0| VNET: MACVNetPort_Connect: Ethernet0: can't open data fd

[code]....

Once xp has booted, I get the "new hardware" wizard, saying that it found an ethernet adapter. However, it can't find any driver for it. I think this dialog started appearing after I added a new virtual network entry using the "Virtual Network Editor". Originally I didn't even have a /dev/vmnet8 file. Now I do.

Ubuntu Networking :: 10.04 Auto Ethernet Says It Connected But Can't Ping Out

Jul 19, 2011

I am unable to connect to the internet at work through the ethernet, previously working. I am not sure of the origin of this problem -- the result of an update or something that I did to the network settings.

In the NetworkManager applet is says Auto Ethernet is connected but I can't ping anything by name or ip address.

The wireless still works without any problem.

I have tried following some of the other threads on similar issues but the fixes proposed on them have not helped to date. And I may have mangled some of the settings files somewhat.

Ubuntu Networking :: Getting My Wireless Printer To Work - Unknown Device Connected To Router

Apr 27, 2010

I had previously been having loads of problems getting my wireless printer to work with Linux [http://ubuntuforums.org/showthread.php?t=1453697]. Everything is working fine now. However, something that confused me is that whenever I tried to ping the printer _before_ I got it working, it would fail with a _different_ IP address. That is, the command 'ping x.y.z.3' would fail with a message saying it was unable to contact 'x.y.z.2'

Now I am looking at my router - for something unrelated - and I've noticed that rogue IP address shows up in the list of connected devices. It has a MAC address but for the device name it lists "<unknown>". Should I be concerned about this? how to figure out what this device is?

Networking :: Ethernet Interfaces - Device Activated On Reboot

Dec 28, 2010

The ethernet configuration files are under
"/etc/sysconfig/network-scripts" such as "ifcfg-eth0:1" etc.

The file looks as follow:
Code:
DEVICE="eth0:1"
BOOTPROTO="static"
ONBOOT=no
IPADDR="172.23.17.10"
NETMASK="255.255.255.0"
ALIAS="yes"

I've set the ONBOOT=no. This means this device should not be activated at boot-time. But as I reboot the machine, this device is activated again. This means the option ONBOOT doesn't work. Seems this is a bug of RedHat LINUX?

Ubuntu Networking :: Says Wireless Is Connected But Cannot Find Server

Mar 1, 2011

Just installed ubuntu 10.04 on my Dell inspiron 1525 laptop. Everything got installed right, and I elected to select the sta driver rather than the B43 driver. After restarting, the b43 option disappeared. The wireless said it connected, but when i went to firefox it wouldn't load and said server not found. My wireless card is a bcm4312. Any ideas as to why this is not working?

Networking :: Increase Storage Space Of Server With NAS/DAS Device Via Gigabit Ethernet?

Feb 8, 2010

Cost effective (the people want cheap) solution to increase server storage space with as little impact on throughput (what I want) as possible. I have a server that sends instructions to 20 clients to perform certain tasks. The clients send gigs of data back to the server for storage.

BACKGROUND INFORMATION
Network: Gigabit Ethernet
Clients: (20) HP, Solaris, Linux
Linux Server: Dell R805 PowerEdge (QUAD Core Athlons 16 gigs of ram, 4 gigabit ports.

Selected directories are mounted (NFS) by clients. One directory to be mounted by the clients contains executable files. Mount commands are sent from the server (rsh) to the clients. Yes I know (ssh) but this is how the software was originally written so let's go with it.

The clients then receive commands to execute the binaries contained within the mounted directory. The binaries basically create an image of the clients filesystem including special applications. The client then sends the files and directories to the server which stores this �image�. This process can be reversed to restore a client to the initial baseline image.

In a nut shell, 20 clients are sending gigs of data to the server for storage. I need to attach a NAS (gigabit) to extend the storage capability of the server. The server would mount (NFS) to the hard drives on the NAS. The NAS, configured as a �direct attached storage� device (DAS), means the storage device is connected directly to the server and not the network (which makes it a DAS). This would provide direct storage expansion for the server. However, this configuration cannot be a bottleneck that significantly hinders performance.

Clients <---data---->Server<----storage---->DAS/NAS

1) Will a low end NAS (gigabit port) work? (NetGear 1TB ReadyNAS Duo, RND2110-100NAS) or something with a higher rated throughput (QNAP TS-239 Pro II)

2) Low end won't work, go with �?

3) Does the processor on the NAS play any role that would determine the performance of this configuration given that the server would mount directly to a directory on this device (DAS/NAS)?

Ubuntu Networking :: Can't Find HP LaserJet 3015 On Network - Connected To A Win 7 PC Through USB?

Sep 1, 2010

I just installed Ubuntu 10.04, 32 bit, yesterday on my Dell Latitude 6500E and I am new to Linux. I can't find my HP LaserJet 3015 on my home network, even though it is connected to a new Windows 7, 64 bit PC thru USB. The other Windows PCs find it fine, and all 4 PCs can see each other on the network. So, I installed the HP software (http://hplipopensource.com/hplip-web...all/index.html) and that went smoothly, but the printer is still invisible. I also added Samba and that works great like everything else. I plugged the printer in directly to my Ubuntu laptop's USB port and it printed instantly. Now, if I could just print to the LaserJet on the network. Anybody got this one figured out? Does Wine provide a way around this?

I recently installed Ubuntu via "wubi", and tried to set up the Wireless. After looking at a few threads, they suggested using an Ethernet cable to troubleshoot the problem. However, my laptop does not detect the router even via an Ethernet cable. I am running 64 bit(It auto-downloaded with wubi) on an Acer Aspire 5553G, and my router is a Netgear DG834G. I have an Atheros AR8151 PCI-E Gigabit controller, a Broadcom 802.11n Network adapter and TAP Win32 Adapter V9.

Networking :: Find A MAC Of Hardware Attached Via Ethernet Cable?

Apr 19, 2011

How can I find a MAC of hardware attached via ethernet cable? I have been working nicely with an industrial scanner that is controlled by a Linux PC via an ethernet cable, but the hard drive has died I need to get it working again. The problem is that the main PCB has a Realtek RTL8019AS ethernet controller chip: [URL] which I believe is used in the most basic way possible, applied straight off-the-shelf and unconfigured. To utilise the chip ARP commands are used to assign an IP address to the chips MAC address e.g. something like:

arp -s 192.168.2.5 00-05-a4-00-a8-f8

Unfortunately the actual MAC address was lost along with the HD Th only thing I could have a reasonable guess at is that the chip will have a default subnet of 255.255.0.0 or 255.255.255.0

Fedora Networking :: Ethernet Connection Stopped Working - Cannot Find Server

Jul 23, 2009

After using fedora 11 for a month or two now the ethernet gave out on me tonight. However if I switch to my ubuntu or windows XP install it runs fine. I made no recent changes to network connections, and no installed programs that should effect it.

kernel version: 2.6.29.6-213.fc11
default connection: eth0(and only connection)
ifcfg-eth0:
# Networking Interface
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:1F:C6:DB:05:0C
ONBOOT=yes
TYPE=Ethernet
IPV6INIT=no
USERCTL=no
NM_CONTROLLED=yes
NAME=eth0
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
DNS1=192.168.1.254
PEERDNS=yes
PEERROUTES=yes

I have tried, restarting, older kernel, restarting services, and clearing the DNS Cache. The specific error I get is that "Firefox can't find the server", and most other applications return similar. I can however ping websites still. All other computers on the network are running fine, and booting into another system the internet will work. Just not for fedora.

Networking :: Unable To Find Atheros AR8132 PCI-E Ethernet Controller Driver For CentOS / Fix It?

Jun 26, 2011

I am unable to find Atheros AR8132 PCI-E Ethernet Controller driver for CentOS which is installed on my netbook.

I contacted DELL to provide me the driver and they said that they do not support Linux on netbook and I have to arrange it myself.

I told them that I don't need help in installing I just need the driver file to which they said that they don't have driver for Linux.

NIC is getting detected and works fine on the same netbook (Am dual booting Windows7/CentOS) with Windows7

When I type: ls -l /dev/ it does not show up eth0. Same result with ifconfig. When I type lspci | grep net it does show up something like Atheros Communications AR8132 L1 PCI Gigabit .

General :: Net Boot From Debian Server Using Directly Connected Ethernet Cable

Jun 23, 2011

I have a computer with grub installed, and nothing else. I'd like to install Debian on it without having to burn a CD. (and I don't have any flash disks.) It has a nice ethernet card, and I have another computer right next to it with an ethernet card. I also have an ethernet cable. However, I don't have any router free which I can mess with for these purposes. As I've looked up, apparently modern Ethernet cards don't need crossover cables, normal cables will work for this type of connection.

I've tried several different "tutorials" on how to set up a netboot server, but

None of them are complete. All of them assume that you understand how DHCP works, and that you can do things like set up a dnsmasq server. I don't understand the DHCP protocol, with submasks and whatnot (I know that it is the protocol for assigning computer network addresses, and that's it), and I don't think I should have to in order to simply connect two computers. All of the tutorials give you incomplete configuration files, and ask you to fill in things which I don't understand, and for me it doesn't make sense to customize these settings, as I just want to connect them and I really don't care what ip address the TFTP server has or whatnot. All of these assume that you are going through a router. I am not. When I try googling for ways to directly connect two linux computers with an ethernet cable, I can't even find instructions, just more references to "you need crossover cables".

So basically, I have two computers directly connected by ethernet cables. Tell me what packages I need to install, what the contents of my configuration files should look like, and what, if any, commands I need to run in order that when I turn on my second computer, and select network boot, it will start up a minimal debian system.

EDIT: Hmmm, it looks like I actually have a linux kernel installed too, but no root filesystem (so no other programs besides busybox).
