Ubuntu Networking :: Apps Do Not Detect Internet
Jun 30, 2010
I recently installed Ultimate Edition 2.7. It works great. My problem is that most of my apps like frostwire, Ktorrent .... for that matter any application that requires to connect to the internet....are not able to detect my internet connection. I'm connected to Auto ethernet....I can browse...All my browsers work though and the OS is also able to connect.

I have just installed ubuntu 10.10 on my windows 7 os as part of a dual boot, and im having trouble connecting to the internet. I have a wireless edimax PCIe adapter and seem to be able to detect the signal fine but when i try to connect ubuntu starts thinking about it and then after a while says "disconnected from wireless internet".
I'm pretty much a noob to lunix but have a small amount of experience with the terminal, also not so great on the networking terms, so please dont go too deep to quick on the terminology!

Using lsof I noticed that everytime I open some apps (like Rhythmbox or Banshee) it connects to the internet over ports 80 and 443. All I'm doing though is surveying my music collection. Why is it connecting to the internet for this? I don't have podcasts or album covers or any of that stuff set. In fact I turned all that stuff off.
the problem is that I only get so much bandwidth on my mobile broadband plan. I don't want apps connecting when I don't need them to. I played around with the UFW but it appears to only allow port configuration. I can't see how to control the connections of applications. I can't block ports 80 and 443 because then I'd shut down the web browser. How do Linux users control the internet connections of installed applications?

In my network I have 25 workstations and some serves. Everything working in local LAN with firewall. The problem is that on one machine (I dont know which one) is installed software which sending data to the internet. Actually I dont know what it is. Last time as I remember was trojan which can create new network interfaces in windows and send some data to the internet. The half speed of my network connection is used by this infected machine. How can I detect which machine it is? How can I listen/capture some traffic and analyze from which machine I have more connections.
Please take a look on this time. Instead of 141-150ms should be 4-5ms.

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?

I have a new F12 install, and my syslog is filling up with messages about USB. I have 2 USB devices plugged in directly to the mobo (bluetooth keyboard receiver, touchscreen), and it keeps redetecting them and then disabling the port for some reason.
A small sample of what keeps on repeating:

To find the appropriate firmware without knowing the make or brand of your wireless chip, you can use the command:
#fw-detect
But apparently debian package do not offer this useful tool, well, certainly for sidux exclusively.
Is there a package of fw-detect eventually?

I recently installed the 64bit version of 10.10 onto my machine, which runs on an Intel DP55WB motherboard. The on board NIC is not detected and I cannot get it to connect to a local wired connection. I ran sudo lshw and it returned (among other items)
Code:
*-network UNCLAIMED

vendor: Intel Corporation
physical id: 19
bus info: pci@0000:00:19.0

How to get 10.10 to recognize the NIC?

I could not connect to any wireless network on my laptop with ubuntu 9.10. Network manager detects all wireless networks avaliable, but could not connect to any of them. When I try to connect, system asks for wpa-key, but typing it gives no result. I tried home and office network, but it is the same. There is WinXP installed on the other disc partition and no problem with wireless connection at all.
I have Acer 3680 with broadcom wireless adapter 4318 (driver was installed via ndiswrapper). I've already spent hours, browsing the Internet, but it does not help unfortunately, so I'll appreciate any advice of experienced user.
Code:
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11g ESSID:"SvoyDom"
Mode:Managed Frequency:2.437 GHz Access Point: 00:1E:8C:E5:12:BE

I recently downloaded Ubuntu 10.04 into my Windows Vista laptop & I have downloaded the one that can run alongside my current system, so I'm running dual OS. At the start up screen where I choose the OS, I choose Ubuntu & it loads fine. Everything looks perfect except that it won't connect to or detect any wireless connections. I have tried clicking the Network Manager icon & clicking New Connection. I typed in the SSID & security key for my wireless connection/router & after I hit create, a small window pops up saying "Wireless Disconnected: you are now working offline" or something like that. Nothing happens/changes. There is no internet connection on Ubuntu OS. But when I switch over to my Vista OS, the internet works perfectly (obviously.)

I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.
desktop: ubuntu 9.10 , wireless and LAN
laptop: windows xp, LAN only

I have a simple home network consisting of 2 laptops - one is a linux box and the other runs windows and linux with a dual boot setup.I develop my web apps on the linux box but would like to test them out on the windows machine using IE7. I have abandoned the idea of doing this in Linux using wine since in the real world this is unrealistic

On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.

I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.
