Ubuntu Networking :: How Networking Works In Lucid
Aug 6, 2010
I am a little confused with the way that networking works in Ubuntu (Lucid in particular). I switch my PC on and my network magically works (ie I dont understand what is configuring everything). I do have a DHCP server, but im not sure which process/file is configuring the interface.There is no entry for my wired interface (eth0) in /etc/network/interfaces.$ cat /etc/network/interfacesauto loface lo inet loopbackDoes this means that Network Manager is then responsible for configuring this interface? How does Network Manager configure this interface (are there config files somewhere that specify settings such as static IP and duplex)?

I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.

I've been running 8.04 Hardy since its first release, and was hoping to deal with its loss of support by going to 8.10 but learned that it has already been dropped.
So I'm back to installing 10.04 - and up against the bizarre choice to drop dial-up networking! Fortunately, I have my 8.04 machine still live, and I've researched it extensively without success.
The best summary of what I've done follows this post I found online:
-----QUOTE-----
I read many threads about dialup, including those on this forum; made sure to get an external hw modem [USRobotics 5637 USB, advertised as controller-based and tested to work in Linux], to avoid the softmodem/winmodem problem.
Using the 10.04 LiveCD, I installed the four .deb packages that are in poolmainwwvdial and in poolmainwwvstreams.
Now I'm stuck because I get errors when I try command line stuff, errors like "cannot open /dev/modem" and "can't find /dev/modem in /etc/fstab or /etc/mtab"
I'm confused; I've read so many threads with so much different info that I can't sort it out. Maybe I'm following info that applied to earlier versions of Ubuntu. Every error I try to fix leads to more errors. Can someone suggest a constrained, step-by-step procedure to ensure I've mounted the modem, added myself to whatever groups, and whatever else I need to do?
I know there's no wizard to make it simple, but is there a checklist or something to help me sort this out? I have the ISP info, DNS primary+secondary server numbers, phone numbers, etc. Is there a UI/graphical path, instead of command line? Had no idea this would be so difficult.

I run a website called [URL], about a week ago I setup Ubuntu at my job (system's admin) to allow my staff to access our servers from there homes (we live in Iowa and its winter so kind of need it with the snow and all), anyways I have it setup with a static static ip address and it does talk to the local network drives
example:
192.168.1.345
But I can't get it to access wan, I have looked over and over to figure out why its not working? Is this enough information?

I installed Lucid several days ago, and have just noticed that SCIM no longer works. I need it for Japanese input, but cannot turn on Anthy. The manual is either nonexistent or extremely terse with a lot of presupposed knowledge.I've installed German, Russian and Spanish language support, along with CJK. I can't even get the SCIM tool to pop up now---except ONCE!Simply reinstalling using Synaptic overlays the existing problem(s), and does not resolve any issues.SCIM may be conflicting with the desktop Switcher applet? Actually, SCIM seems to be conflicting with other Gnome desktop shortcuts, as well

i am always using the latest version of ubuntu,but my main board of my acer5520g broke down under 9.10 last month,the acer company changed my main board and i installed 8.04-i386 LST for safety. but i find the wireless card does not work, i search the google for help,it seems i should install madwifi,but i found no valid download,after a lot of attempts i surrender. SO i put up this question i need a driver for my wireless card (notebook type acer5520g ,wireless card AR 5B91(detected under windows (though i am a big fan of linux and a supporter,i am using two systems and waiting for the 10.04 LST to save me from virus braced windows)
i even can not detect the wireless card under ubuntu 8.04 but it works ok in 9.04 and 9.10 after the installation.

I just updated my system to a new kernel with the update manager and now my WICD no longer obtains an IP address. Everytime I try it says "Connection Failed: Unable to get IP address".It was working fine before and even when I reboot into an older kernel it still doesn't work.I'm using a Belking Wireless G adapter.I would have tried downloading another network manager but since I can't even access the internet I'm stuck with changing current settings and nothing seems to work.

I am having an issue with a newly installed 9.10 version of Unbuntu. After a bit of fiddling about, I have found that the only way I can connect to my wireless network is if I unsecure the network. Is there any explaination for why it will not work with either WEP or WPA?

I've got a Dell Inspiron mini 10 that has the Broadcom 4322 wireless chipset in it. I have NEVER got this thing to work satisfactorily despite the numerous tutorials online about getting this damned card to work. I thought everything would finally be fixed with 10.04 but no luck at all. I've tried the b43 diver (which isn't supposed to support the 4322) with no luck.
I also tried the restricted STA driver, which seems like it will work as it identifies networks and even connects to them! However, the speed is excruciatingly slow and connections drop like flies. This netbook is actually a friends that I convinced to let me put Ubuntu on and have them try it out, but they are most surely not going to be impressed if the wireless never works.

When in XUBUNTU i click the picture of the 2 pcs indicating a network and choose "connect to hidden wireless network", put in the information.All this works nicely. When i reboot it's saved my config so i choose it to connect again but the "connect" button is disabled so i have to config it all over again and then it works. How do i get it to just connect to the network on login?

I have two Roboards that need to communicate with one another. I have sucessfully installed Ubuntu 9.04 using the 386 kernel based on instructions found online.I can use the GUI to set up an Ad-Hoc network using one Roboard ("Create New Wireless Network"), call it Manet, and connect to "Manet" using the GUI on the other Roboard and ping/ssh between the boards. However, when I try to create the same wireless network using the command line using:
ifconfig wlan2 down
iwconfig wlan2 key off essid 'Manet' channel 5 ap any
ifconfig wlan2 up
I don't see any entry in iwconfig under "Cell". It keeps giving me "Not Associated"When I try to enter the same information on the other Roboard to try to connect to the network, it doesn't connect and under iwconfig, I don't even see any entry for ESSID. Could somebody please tell me why it works when I use the GUI and not the command line.

I'm facing a problem when I establish VPN connections using OpenVPN to Your Freedom Server. " you can see their documentation here ", I've installed OpenVPN from synaptic and I used the client to connect through VPN and it works !! but there is no traffic in FF or any application !!I tired to insert some HTTP proxy also belongs to the same server and it works. What really wonders me is that OpenVPN seems to work only when I'm connecting to streams sites "e.g. ustream, justin.tv" Is there anyway to force the whole traffic to use OpenVPN " I'm using Mobile modem and it works fine with OpenVPN in win7

This has been bugging me for quite a long time. I need to have a pptp connection to my university. I have tried to locate the error, but this has been a real trouble.
A little bit of history: My girlfriend had a laptop with M$ vista on it with a working PPTP connection. I had a laptop with Ubuntu, with which I couldn't get the PPTP working.
When my laptop crashed, I bought a new one on which I run a dual boot XP SP3 and Ubuntu. I also own a desktop (Dual M$ Win 7 / Ubuntu standard Karmic) and my girfriend also upgraded to Win 7.
Currently, the XP version is the only one on which I can get a connection. Both Ubuntu and the Win 7's give me a GRE proc 47 not received error. I know our router (a DAVOLINK DV2020) is notorious for not sending through GRE proc 47, but this either shouldn't be the case or it shouldn't matter, since I can make a perfect connection through the XP OS.
This is quite a handicap, since we both study at the university for which we require working VPN PPTP connections.
Settings:
Gateway: vpn-eur-pptp.eur.nl
Username: 123456ab@eur.nl
Password: password
Authentication: MSCHAP / MSCHAPv2

I have a pretty beat-up laptop, on which the inbuilt wireless doesn't work, and so I now have an ASUS WL-167g, which is acting up!It almost always connects to the required networks without an issue, but then once I'm connected it's REALLY slow on some of them! For example, while I'm at school, it works flawlessly! And at a couple of friends' houses, it works too! however, at home, and at a couple of other places, despite the fact that it connects, its so slow, that google takes like 5 mins to load and searching for anything on google leads it to time out!! This happens whether I'm right next to the router (full signal strength) or 2 floors up (at like 3 bars strength)!
It's getting pretty frustrating to have to swap my lan cable between my desktop and laptop constantly, and also to not be able to use my laptop away from my desk!Does anyone know what might be going on??Also, while i have you guys here! I have another problem -- with the inbuilt card.. Initially, it wouldn't work at all.. but more recently, it has started to function (it connects and works on my home network fine) the only problem is that about 10 mins after I turn the wireless switch on on my laptop, it hangs! (EVERYTIME) (if it's relevant, my laptop is a SONY VAIO VGN-S46GP). Again, any input would be appreciated!!

Ubuntu, been using windows for years and now use Mac. I have Ubuntu running on a netbook at work and all of a sudden my wireless connection not only doesn't work, it doesn't seem to exist! Wired still works fine, but the wireless option has vanished. How do I reset or restore or whatever it takes to get my wireless working again?

I know my pass phrase, I know my encryption type, I put that info into the wireless utility for GNOME and it works. I Just recently installed the Kubuntu desktop from the repos and tried to connect to my internet wirelessly and for some reason it can't establish a connection. Is there some option I don't know about that was being set for me automatically before?
Here is my wireless info:

In a separate thread I discuss my issues with getting my Blackberry 9650 tethering with Verizon and Ubuntu 10.10 with bluetooth. I'm still hoping to get that working, but in the mean time, I've actually started to think about perhaps getting a mobile broadband card from a US provider separate from my blackberry anyway - preferably one that works right out of box with Ubuntu.
Does anyone here have any recommendations? I know there's a lot of compatible devices, but maybe someone here can recommend a provider (I don't have to stick with Verizon - willing to go AT&T, T-Mobile, Sprint, etc.) and a USB mobile broadband device that'll work pretty smoothly?

After upgrading to Ubuntu 10.10, I've had difficulties with my wireless connection. It will work for a few hours just fine, then suddenly disconnect and try to ask for my password several times before giving up. It's not the network--another computer on a different OS is having no such problems. Also, my wired ethernet connection works with absolutely no problem.

I'm trying to use a remote procedure call. When I call my server, my server should activate gammu and send an sms with it. I've used the code in the following tutorial: [URL]. The command for the uptime, and the command for the greeting work perfectly. But when I write my own method on my server, it fails ..
Code:
function uptime_func($method_name, $params, $app_data) { return `uptime`; } function greeting_func($method_name, $params, $app_data) { $name = $params[0]; return "Hello, $name. How are you today?"; }
function gammu_func($method_name, $params, $app_data) {
$text = $params[0];
$number = $params[1];
$result = "echo '$text' | gammu sendsms TEXT $number";
exec("$result");
return $result; }
On my Client (the one that calls the server) I see the output of $result. So my gammu_func is definitely working... He just doesn't execute
Code:
exec("$result")
I know that syntax is right cause I tried it in a different php file. I think it has something to do with the user rights. I don't think I have the privileges to run that command ...

I've searched around and seen that other people have had this issue but I haven't seen anything on how to resolve it.

anybody out there with an idea for a command to make the WLAN-Printer (HP-Officejet)work again when it stops after 30 Min - 2 h.Simple stopping the print job and print again does not help. The only way for me is to stop the print job and RESTART. Then it works again 30 Min- 2 h. I use updatet lucid lynx 32.
And I need a command like "killall pulseaudio" that I need when I return from logged-on as the second user to get sound again.

just joined the forum so I am a little lost. I am trying to get my wifi to work on an HP Pavilion tx 1115nr (tx1000 series). I am using Ubuntu 10.04 desktop, my network card is BCM4311 rev1.I have read many threads and tried about everything, but I am so close. I can load bcmwl-kernel-source from the software center, restart and my wifi works for that startup. If I restart my computer again, it no longer works. I can then remove bcmwl-kernel-source and reinstall it and it works just once again.I have blacklisted b43 and ssblsmod reveals that these modules are missing after restart when wifi doesn't work:
arc4
lib80211
lib80211_crypt_tkip
