How can I track down what's using my nic and kill it (if appropriate). There are no applications running which might be authorized to send and receive packages, so I don't really know why the System Monitor shows network activity.
View 9 RepliesI tried to do a scheduled software update several times today (8/20/11) and nothing seems to download, though I do get the "Downloading" PackageKit dialog message (the System Monitor shows practically no network activity). In between tries I downloaded some 600 MB .iso files (about 10 minutes each) so I know my internet is working properly. That leaves either PackageKit got hosed in my last update, or servers are down.

The format is always the same, though sometimes the address is a regular Internet site.
The only window that's open is the terminal running this command, no pidgin, skype, samba, torrent or anything I can think of is using the network yet there is ***** load of output from tcpdump. I was hoping to use this to check where certain applications connect to and what messages they send but when I'm doing nothing there is already more output than I can go through. Running tcpdump for less than 10 seconds gives me the following output:

Was wondering if this is normal. I have a laptop which is about a year old. Recently my battery died (it last 10-15 minutes instead of 3-4 hours as it was before). I ordered a new one. While waiting for the new one I started to investigate power consumers (processes) on my machine. I run slackware64-current. with 2.6.33-rc4-git7 kernel. config - is slightly modified config-generic from -current. I attach t here for any case. Here is the output of powertop:

I bought a nice new Acer Athlon II x2 yesterday with the intention of using it as my main stable, every-day system. As it came pre-installed with Windows 7 Home Premium, my plan was to dual-boot between W7 and an as-of-yet undecided 64-bit Linux OS (probably Slackware's 64-bit variant).
Anyway, it wouldn't connect to the Internet. Everything else seemed fine but this. Being too lazy to really look into it myself at the time, I called up Acer tech support and shared my problem. We did a ping test and she said the problem's with the ISP not the hardware, so I went there to find many of their customers seemed to be getting bad or no connection. Thinking that was likely my problem too, I left it at that.
Well today after work I decided to boot my Puppy Linux USB stick onto the machine to see if it's just W7 being Microsuck, and attempting to connect, Puppy couldn't find the correct module to load that would result in a new interface (network) being detected. Annoyed, I tried Puppy Linux on an old tower I'm currently working on for my parents (still working on that one btw for anyone who remembers me from last week) and it connected fine. I'm actually using that system as I type out this post. Running other Linux OSs on my new machine does the same thing (no connection). Going back to W7, I tried letting them do their diagnostic thing and it came up with this:

Code:
sudo add-apt-repository ppa:dockbar-main/ppa
sudo apt-get update
sudo apt-get install dockbarx
DockbarX was working.
Then I uninstalled Cairo and AWN with Synaptic.I got a notification of an error in the panel saying I had broken packages - see broken package filter to check it out.I can't find filters in Synaptic.Then I noticed DockbarX was empty (and I had pinned Firefox to it) So I tried uninstalling and reinstalling via terminal. No problems with that but when added it to the panel again it was still empty . I rebooted several times during these attempts.

View 9 Replies View RelatedI have a number of diskless hosts which are to bootth PXE and mount their root filesystem on an NFS share. Most of the NFS share will be common to to all of the diskless hosts. No problem with that part.I also need part of the NFS shared filesystem to be unique to each individual host. The only difference between the hosts is the ethernet MAC. I use it in the DHCP server to key a specific unique IP to each host. I would like to be able to use either the MAC, or the IP, or any other unique identifier that can be derived very early in the boot process to access a filesystem or directory that is unique to each diskless host.
I need/want to do this because I need/want to isolate all of the system maintenance to one small part of the boot host. Modifying the hardware (these are VME CPUs) in any way is not an option; they must be field swappable, with all maintenance isolated to the boot host(s).I know I could run ifconfig and parse its output to derive an IP &/or MAC, but that seems a bit kludgey and fragile. The DHCP server is presently assigning IPs. I know I can arrange to pass a unique option value via the DHCP server, but don't know if or how this can be retrieved on the diskless nodes. I am presently passing the 'root=' kernel argument from the bootloader, but I don't think there is any way to pass other filesystem information using that mechanism.
I know I can pass some kernel arguments from the bootloader, but there doesn't seem to be any generic message that can be retrieved in userspace as part of the boot process. I've scanned around in the /proc filesystem, looking for the IP or anything else that seems to uniquely identify the host, but don't see anything there, either.The init process has not yet been cast in stone, but is very likely to be a BusyBox built-in
I have an acer aspire L-5100 with Vista and fedora dual boot configuration. Fedora 11 worked fine. After upgrading with preupgrade The system shows a strange behaviour. The startup screen ( with no the little f in the first ) is first blue with the white place in the middle , the filling with the fedora f very slow ( 5 minutes ) and then nothing. No harddisk or network activity no booting. <ctrl><alt><delete> works for rebooting. <altfx> for console not. Hacking <alt f2><esc> very often and fast leads sometimes to a console where then the boot process starts running and the system comes up with gnome.
View 5 Replies View RelatedI'm after fresh install of Fedora x64, did all updates. I have wireless pci card TP-LINK TL-wn510G (Atheros chipset) which was detected correctly.
Everything is working smoothly until I start to download from internet in firefox (or in konqueror - no difference). On increased network activity my mouse cursor starts to lag/jump when moving - it's almost impossible to do anything using mouse when there is file download. On minor traffic, like browsing webpages, I don't notice such behaviour.
I checked if its rather because of hdd activity not the network, but no - when copying big file on hdd everything works fine.
I'm also experiencing huge ssh lag/jitter despite the ping is low.
I fired top when downloading, but there is no process eating cpu in suspicious way.
I have a regular usb mouse.
On the same computer I have installed Win 7 and OpenSuse and nothing like this happens on that systems.
I think there might be a some kind of conflict between wifi card and usb mouse (they share resources) but don't know how to check/repair. Could you please tell me how should I proceed to check what is going on. I haven't modified any hw settings, the installation went w/o any errors.
I had a problem with the new network manager a week ago and got it solved with help from the forum so now I'm back again. I have a dual boot with Windows 7 (I have to use it when serving my corporate masters) so I wasn't in my Fedora partition much this week.
I just noticed this and I'm positive it wasn't doing it before my network manager problem but I'm not sure when it started or if they're related.
I'm running F15. The machine is an HP Elitebook 8440p and has a wifi light that is also a touch button to turn the wireless on/off. Whenever there is activity on the network now it blinks between orange and blue. I know that isn't really a big deal but it's really annoying and is driving me completely nuts!! The normal behavior is orange when it's off, solid blue when it's on (or connected) and blinks orange/blue just while it's connecting. During network activity it's always been just solid blue and that's what I want.
I found a script that some Ubuntu users said fixed the same problem but when I tried to copy it the directory they said to put it in "/etc/network/ifup.d" doesn't exist. I'm assuming that's a distro difference between Ubuntu and Fedora?
Has anyone else seen this? Any ideas how to fix it?

View 4 Replies View RelatedI upgraded from Fedora 10 to Fedora 11 last night in response to a pop up window. When I rebooted after the upgrade my wife immediately complained about the internet not working. Actually the connection up was working but Fedora 11 upgrade had made it slow almost to a stop There are two XP machines the network behind a local D-Link wireless router with Comcast high speed internet. When I disable networking on the Fedora machine the internet connection immediately returns to normal on the other two machines. Also there is a second or two period after enabling networking for a quick upload or download before the connection clogs.I checked the system monitor network history and found that there is a constant networking send rate of just under 180 kb/s in the background.This occurs even when the browser, email client, and automatic backup are off and the only process showing significant CPU use in the system monitor is the monitor itself.
I tried netstat but there were so many /tmp/orbit entries that I could not scroll up to the top of the listing. Is this normal. If so, does anyone know the netstat command options to just see connections with sent packets. I also tried ifconfig -a. This shows no Rx packets at all, and no TX packets except on eth0, The total etho TX packets matches t,he reported by the system monitor, and in the monitor you can watch the total accumulate in approx 180 kb/sec increments. I don't understand why 180kb/sec TX would make a dramatic difference in internet network internet speed. Comcast reports upload speeds in megabytes. I need to be able to use the net in Federa, but I am also curious to learn what is the caused the problem.
I have 4 workspaces set up and they appear on the bottom menu bar. Usually I can switch to each and see what's running in each, even if the apps are minimised. Now I can only see what hasn't been minimised, and I can't see or return to the ones that are minimised... System Monitor shows the minimised apps are running... I was poking around gconf editor late the other night and I must have altered a setting but I have no idea which. I've looked through docs etc but can't find a solution.

I really do not know how to phrase this question properly. I am quite unaware of the PC jargon. But I have Ubuntu as the main OS and Mandriva is the second OS on the same hard disk. The boot loader is the Ubuntu. When I want to switch to Mandriva, on boot up I press Shift and then select the kernel.However, if I am on Ubuntu and want to run an application which resides on Mandriva, how do I do that? My fstab file does not even mention Mandriva. However, the file system does show up that file and I can open any files I need by clicking on GUI "Places". But when I try to run any of its applications by clicking the appropriate file on its /bin file nothing happens. A pop-up window briefly flashes and disappears. So my questions are:
1. First how can I change directory so that I am on Mandriva. Can' cd ...something' take me to that file because I see it in "Places" as a 36Gb file system?
2. How can I run an application which resides on that file system e.g., R or Octave which I do not have installed on Ubuntu, without rebooting into Mandriva.
3. Can I do this from command line.
4. And finally, can I do the same from Mandriva i.e., access Ubuntu from it.
I did read quite a bit about mounting files and fstab, but the fstab does not show the file system I am talking about. These are the outputs from Ubuntu os.
