Ubuntu Networking :: Server Doesn't Find My Other Network Devices
Jun 30, 2010
I've got three network devices on a laptop:
1. Built-in ethernet LAN
2. Built-in ethernet WLAN
3. PCMCIA ethernet LAN
I installed Ubuntu Server on this computer without the last one inserted.I inserted the last one today, and it lights up when i put in the cable. To be sure if Ubuntu has found it, I tested with the install CD and could see that it found all three at the first part of the installation where I have to chose a primary device.I can't get my WLAN card working, neither do I get my PCMCIA LAN card working. The third card, this PCMCIA card, has worked on Ubuntu Desktop using another laptop. And as said, the setup finds all three.

recently I risked a look to the Linux world and I'm happy so far, but now I've got a Problem, I'm unable to solve by myself. I installed Mint (Julia) on my old Laptop to test Linux. The Laptop has a very old PCMCIA WLAN Card with a Realtek rtl8180 chipset. Everything seems to run perfectly so far with one exception: the WLAN doesn't find any Network to connect although the card and the driver seem to be installed correctly.
Here some code from the terminal:
Code:
lspci
00:00.0 Host bridge: ATI Technologies Inc RS200/RS200M AGP Bridge [IGP 340M] (rev 02)
00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 340M]
00:02.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
00:03.0 Modem: ALi Corporation M5457 AC'97 Modem Controller
[Code]...

I'm trying to connect to my 1st gen iPod touch using an Ad-Hoc network, but I can't find it on my iPod. I want to use it to do a presentation, not internet share or anything too complicated. I set the network up as follows (I'm on 10.10 by the way). Create new wireless network > Network name: xyz Wireless security: none - Create Then I went to edit connections and set an IP address and subnet mask and gateway (to 192.255.0.1, 255.255.255.0, 1.1.1.1 respectively) and set Band to "B/G 2.4 GHz". My iPod doesn't seem to be able to find the network. (It doesn't show up and typing it into "other" it "can't find the network xyz")

I've followed the guide at URL.... but my computer is unable to find any Bluetooth devices. Whether I'm using the command line or gnome-bluetooth, I don't get any results. If I plug in a cheap USB adapter, I'm able to connect and use the devices.My computer is a HP ProBook 4330s running Debian Jessie. And as far as I can tell the Bluetooth adapter is a Ralink rt3592 combination Wi-Fi and Bluetooth PCI card. The Wi-Fi works fine, but when i try to connect to a Bluetooth device, I get no search results.

How can I find all the devices(printers,etc...) and computers along with their OS if any installed that are connected in my intranet (devices/computers may be down here)?
I did this earlier using netstat or nmap not sure what I used and how I did.

i'm experiencing some weird behaviour: I have a server running ubuntu 10.04 and two Apple laptops in my home network. Sometimes after booting up the server doesn't connect to the wireless network, but instead "kills" the connection of the laptops. (The network then isn't available for about two minutes - it's showing but it can't connect) On the server the network interface is up, but not associated.
Sometimes the interface isn't configured properly (iwconfig isn't showing an entry) - but in this case the behaviour obviously isn't showing. some information about my system:
Ubuntu Version: Server 10.04x64
Wireless Card: Netgear WG311v3 with marvell chipset
Driver: ndiswrapper+mrv8335x64

I'm setting up an LTSP server using Ubuntu 10.4 64bit, and PXE connecting with thin clients using Atheros cards. The ltsp environment is 32bit.
Unfortunately I get an error message with "No interfaces found! Aborting..." and a kernel panic early during PXE boot.
After an enormous amount of investigation, I've narrowed it down to (probably) being the fact that the ltsp chroot environment doesn't have the correct driver for my network card (I believe it's atl1c). The correct driver IS available in Ubuntu, though, as I can successfully boot the thin client from both 64bit and 32bit live CDs and bring up the network interface.
how can I install the correct driver in the PXE environment?

Just built a box and once 10.04.2 64 bit was all installed and loaded up I realized instead of showing my Ethernet as connected it had the ol x. So when I clicked on it I got "No network devices available." The mainboard is an Asrock 890GX Pro3, link light completely out.

I'm having mysterious wired network problem with my Karmic/9.10 machine. It hasn't been in network a while, but now I finally got the cabling done. I can't get the IP from dhcp server (TW-EA510), and static settings doesn't work either. Fresh cabling showed OK 1Gb connection on tester, and win7 laptop works fine. I even tried with long cable though the rooms, but it doesn't help, so it definately isn't the new cabling.
Log from the router after issuing #"dhclient":
Feb 16 23:01:43 DHCP SERVER: DHCPDISCOVER from 00:01:29:fb:c5:d1 via br0

Motherboard is some old Lanparty with two ethernet ports, NVidia CK804 and Marvell 88E800 rev 13 Gigabit netwok adapters, neither of them works. At least another of them has been worked earlier when I last got it wired. It's been a while, so I'm not sure which one of them and with different router if that matters.

I've got a co-worker who is trying to connect multiple devices to his wireless router - Xbox, Wii, TV, Dishnetwork box, etc. Not all of the devices are wireless however. He's had several thoughts on how to get this done and I know very little about this kind of thing so I thought I'd ask some of you.
His first thought was to buy a multi port bridge, but he doesn't like any of the ones he's seen so far.The other thought was to connect all of the devices to a switch and then use a single bridge, but he isn't sure if this would work.

I am running Ubuntu 9.10 and Windows 7 (Wubi). Windows Networking shows all devices on the network (computers, routers, etc). Is there a way to get Ubuntu to do this (Would prefer GUI)?

I'm doing a few tests with fedora 15. I'm surprised because they changed the naming way on network devices. eth0 is now called em1.At every fedora I have found the configuration files in /etc/sysconfig/network-scripts, but today I can't find them.

I just loaded 10.10 on an Acer Aspire One D255. When I installed Ubuntu, network manager loaded and I was able to use both the wired and wireless cards. After I used update manager, the kernel was upgraded, and I also added some wireless applications (RutilT WLAN Manager, SWScanner, and WiFi Radar). Upon reboot, the network manager doesn't work, and it cannot find any of the devices.

Does anyone know of an application that continually scans for devices on a network and notifies you if a device connects/disconnects to/from the network? I just want a way of knowing when a computer is connected and when it's not.

I boot linux off a USB stick on many different computers with different hardware. How can I determine in a script which devices eth0, eth1, wlan0 exist and which hardware devices they apply too? Sometimes a wireless card is wlan0, other times it is eth1 or even eth3! The proc/net/dev file does not inidicate which hardware is installed.

I have not tried this, and I am only wondering about the result.Let's say that I have a PC/Laptop with two network devices: an ethernet and a wireless. Can I connect both of the to the same network (if this network allows both connection) to increase the transfer rate between the PC/Laptop and the server???

This may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.

I cant get openSuse to find my wifi adapter or it does not have the driver installed.
My wifi adapter is the Realtek RTL8191SE 902.11b/g/n
I found a linux driver on the internet, but it asked me to run make in the console and when I did so it said that it couldn't find make.
how to install make from openSuse without the internet (I'm using my windows partition).

How can I login to some devices that are behind my Server?
My topology is:
So, what I need is to access these VOIP ATA's web interfaces using port forward not using PPTP connections.
Example:
x.x.x.x:2020 ===>> VOIP ATA1
x.x.x.x:2021 ===>> VOIP ATA2
x.x.x.x:2022 ===>> VOIP ATA3
Where x.x.x.x == >> Static Real WAN IP
VOIP ATA1 IP == >> 10.10.10.47
VOIP ATA2 IP == >> 10.10.10.48
VOIP ATA3 IP == >> 10.10.10.49

I'm having trouble getting my wifi devices to work on my 128bit WEP network. I have a new Thinkpad T400, with an internal Intel PRO/Wireless 5100 AGN. I also have some cardbus cards: a Lucent ORiNOCO Gold, a Linksys Wireless-G, and a TRENDnet TEW-421PC. I have them set up as interfaces eth2, eth1, and eth3. (The TRENDnet isn't recognised as a network card at all, so no interface for it.) I have installed the latest firmware for the Linksys card.
The /etc/sysconfig/network-scripts/ifcfg-* files are virtually identical for all of them, differing only in the HWADDR and DEVICE lines. So here's the behaviour:
1. The Lucent card comes up just fine.
2. The internal 5100AGN and the Linksys cards won't come up, and watching with iwconfig shows that they're either associated with my AP OR they've got an encryption key set -- but not both.
3. When trying to bring up the 5100AGN, I get the following messages:
iwlagn: index 0 not used in uCode key table
iwlagn: index 3 not used in uCode key table
/var/log/messages shows DHCPDISCOVER requests being sent, but they're bound to fail since the association with the AP with WEP isn't being completed. And yes, the ifcfg-* files really *are* identical except for the DEVICE and HWADDR lines. The /etc/udev/rules.d/70-persistent-net.rules file correctly maps the interfaces to the MAC addresses. So why does my antique ORiNOCO card work and thew newer ones fail? How can I track down what's being done wrong/not being done?

I just installed skype 2.1 beta 2 (the deb file) from the skype website, but the only option I see under Sound Devices -> Recording is "PulseAudio Server (local)" This doesn't work for me, as the skype test calls don't actually record anything I say. I use skype a lot and FINALLY got it working under karmic, but I needed to upgrade to lucid and now it's broken.
When I open Sound preferences and look at the Applications section, Skype shows up as recording when I run its test call... but no sound is recorded? How is it possible that my sound card picks up something recording but doesn't actually record it when I'm in skype?
