Ubuntu :: How To Temporarily Disable NetworkManager
Aug 12, 2010
I'm looking to temporarily disable NetworkManager while I configure some things in a shell. It's interfering by auto-reconnecting and using the network interface in the process. I've tried killing the process but that just seems to disconnect the network not kill the NetworkManager applet. I don't want to uninstall, and I don't want to have it disabled on startup. I just want to "close" it or "turn it off" temporarily! How can I do this? Also, I'm using 10.04
In order to be able to concentrate, I would like to have an applet (or script) to temporarily disable notifications.In the same spirit of Caffeine which inhibits the screensaver when activated.I saw this tip, but would like something which does not require reboot
Having an issue with PlaneShift in regards to this error in terminal:
Code: Inconsistency detected by ld.so: dl-close.c: 731: _dl_close: Assertion `map->l_init_called' failed! On search of the PlaneShift forums, I saw someone state disabling OpenAL would fix this.
I've searched Google and these forums, but still can't find a guide to disable OpenAL. So how would I go about disabling this temporarily so I can get PlaneShift working?
I'm currently trying to learn how to get around Blender, but I keep running into the same problem. Blender relies heavily on shortcuts and keystrokes to navigate it's GUI, but very often they clash with the shortcuts on my desktop. The result is that the desktop shortcut wins, making Blender impossible to use effectively.
Is there any way to disable the desktop shortcuts temporarily while using the software, and then setting them back when I'm done?
Is there any way to temporarily "switch off (and back on)" the internet connection on a system (that runs linux)? The following methods are not allowed:Turning off the router. That would lead to a lot of angry young individuals. This method must be particular to my workstation.Use root privileges (coz I do not have them). Yank the ethernet cable from the system.Why: Sometimes the internet proves to be a distraction.I am using the following system: Fedora release 11 (Leonidas), linux kernel 2.6.30 and GNOME 2.26.3
I just tested Networkmanager on OpenSuSE 11.2. I tried with my wired connection and it works.
I thought I test to connect with network sharing with my Android phone. The Android phone connects according to Networkmanager, but I'm not sure if it actually works as the wired connection is still active.
I tried to figure out how to disable the wired connection, but eventually gave up and just pulled the wired network plug.
But surely, there must be a way to disable connections from Networkmanager?
does anyone know a way to disable those annoying NM 0.7.1 popup balloons in F11 (KDE)? The ones that say that it is now connected to the wired eth0 network for example? I would really like to get rid of those ugly GTK notifications in KDE, but the NM GUI doesn't seem to have an option for this?!
When connecting to my Ubuntu box from my Windows 7 machine via Telnet, the session will sometimes freeze for a few seconds before allowing me to continue typing. This seems to happen every few minutes. Both machines are wireless and I am connecting through my local network.
I've been attempting to install Virtualbox 3.1 on my desktop using the "Add and Remove Software" facility. All attempts result in failure with the "Details" error message box issuing

How do I temporarily but completely uninstall Ubuntu 10.4? I can't locate it in my registry, either using RegEdit or Revo Uninstaller. This is temporary. I will re-install on a different computer of mine that has much greater memory.
I have had ubuntu installed for a few months now and have been loving it. Yesterday I wanted to get JDK installed for a found a forum that said how to install it on ubuntu. The installation was not a success (I am not sure why because I am not skilled when it comes to the command line and I didn't understand the error). Later, I tried to install a different application just through the ubuntu software center and it said it was waiting for a different software manager to finish. I didn't understand what was still running because I had all other applications closed that I know of.
Once I restarted the problem was the same. Then I found a bug where people had the same problem with the software manager and they entered this and fixed it: sudo dpkg --configure -a Now whenever I try to apt-get anything I get: E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Today when tried to install a software from the terminal...d command dint work. Check this.
calvin@calvin-desktop:~$ sudo apt-get install pidgin [sudo] password for calvin: E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? calvin@calvin-desktop:~$
It says that it cannot get lock! I have installed ubuntu along with windows! and drive E: is in windows.
I have been experiencing issues when switching users since my last update; I filed a bug, but I was interested if anybody else was having the same problem:URL...In a nutshell the computer freezes temporarily during the switch user process. The longer it is running, the longer the freeze lasts. When frozen the screen is black except for a mouse pointer; but the mouse and keyboard are not responsive including the usual X command keys (Ctrl-Alt-Del, Ctrl-Alt-Bksp, Ctrl-Alt-F1, etc.).When I get the chance I am going to rollback gdm to see if that makes a difference.
As part of my job, I have to configure a lot of network devices that are configured through web pages. This generally means plugging in to them via ethernet, going to their default IP address and reconfiguring them. I set my IP address using ifconfig, which is much faster than plugging numbers in to networkmanager's GUI. The problem is, NetworkManager seems to take the interface down at random.I could disable NetworkManager but then I don't have a wireless connection.Is there a way to tell NetworkManager to temporarily ignore what is happening on a specific interface or should I just ditch NM altogether when doing this kind of work and use wpa_supplicant to get on my wireless?My co-worker with the Windows machine is looking over my shoulder and chuckling
Is it possible to temporarily enable all repos from within the command line? It would be useful when searching for packages. ie yum enablerepo=* search tint2 (which doesn't work btw!)
This is probably already on these forums, but I recently re-installed suse 11.3 and had the desktop effects working fine with the desktop cube animation and everything. But not the case this time...I resume compositing, and try my desktop effect shortcuts, but nothing happens and it comes up saying for me to press Alt+Shift+F12 to resume the compositing again. I do that, but still nothing, and I even re-apply the desktopct settings completely and restart the computer and it comes up saying that none of them were activated or something in the notifications pop-up on the bottom right of the screen. I thought I downloaded the right files (OpenGL??) from the repositories along with basically anything I thought would make it work.
Midnight Commander startup is usually instantaneous, but when the network (eth0) is down, mct takes over a minute to start.This is a known problem. See:#40 (savannah: MC doesn't open if network gateway inaccessible.) (07 Jan 2007)for example. The problem seems to be caused by mc's use of samba. Is there a known solution or circumvention? The above file advises me to "comment out the eth0 interface from the smb.conf "; however, my /etc/samba/smb.conf seems to have no eth0 interface.The "man mc" file mentions that "smbfs" is one of the virtual file systems used internally by mc. I tried reducing the "vfs" timeout in the ".mc/ini" file from 60 to 5, but this had no effect on the startup time.
i was fiddling with some new commands i learned and typed something weird. Then bash broke on me for a while. here's the command i typed while in /bin bash > lessi believe i was in "sudo su" as the moment. i want to understand this because when I typed it bash didntork. i tried to type "ls" after and it didnt result in anything.but thats not all it didnt receive any commands.Was this a crash? and why/how did it fix itself after i logged off.
I'm working a program to implement a simple multi-process browser. The browser works by having a ROUTER process as the parent of everything else in the program. There's another process called the CONTROLLER which is part of where the user can input information. To tell the ROUTER to make a new tab in the browser the user activates a function from the CONTROLLER to send the create new tab information to the ROUTER:
I have a few updates that I can install using the Update Manager but when I click the "Install Updates" button I get this pop up window message E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable) E: Unable to lock the download directory How to get the updates?
Using ubuntu 9.10 Karmic 64 bit Firefox version: 3.6.9 Mozilla Firefox for Ubuntu canonical - 1.0 about:config is default Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.2.9) Gecko/20100825 Ubuntu/9.10 (karmic) Firefox/3.6.9
When I access some websites, especially certain forums or atempt to post, the tab seems to be loading but doesn't do anything. If I then exit firefox I cannot ping anything (IP or address) in terminal. If I then open Epiphany it fixes everything until firefox next does this. This is happening from 1 - 10 times an hour and is starting to get to me.
I currently have two hard drives, with my root partition configured in RAID0. I'd like to add two additional hard drives, and include them in my RAID0 array. I need to recreate the array to do this, so I'd like to copy everything off of the existing array, add the drives, build the new array, and copy everything back. I have an external hard drive with four times the capacity of my current array. What would be the best way to copy this data so that nothing is missed, so I can just copy everything back and boot back up? dd, image the entire root partition, mount it after creating the new array, copy everything back (at the filesystem level) dd, image the entire root partition, write it back out to the new array, I'm not sure how this would work, because the partition will be the wrong size, I don't know much about dd. rsync, just rsync everything on root over to the external something else? I plan on booting to a live CD and mounting my current array there, so I won't be working on a live filesystem.
I've got an Asus EEE 1000HE, and it's worked fine for a long time with the EEEBUNTU distro (a distro based on Jaunty (i think) with a custom kernel). Unfortunately, Eeebuntu is no longer maintained, so I recently did a clean install of Ubuntu 10.04.2. I am now unable to get my wifi to work reliably.
The wifi tries to connect for a while, then pops up the "Wireless Network Authentication Required" window. If I hit "connect" it will try again for a while, then pop up the window. Etc. Note I know that my connection information is OK. I haven't mistyped the password (see below). Also note that the wifi antenna is turned on. For example, iwlist scan is able to find my network.
There is a weird twist though: The netbook is always able to connect through an ethernet cable on eth0 just fine. If I boot the netbook with the ethernet cable plugged in, the wifi instantly connects as well! I can then unplug the ethernet cable (eth0 goes away), but I am still able to use the wifi connection for about 5 minutes before it disconnects, and goes back to trying and failing to connect.
This behavior is 100% replicable--the wifi always works fine (for about 5 minutes) if it boots with the ethernet cable plugged in. Very rarely, the wifi will also connect on boot without the ethernet cable, but that is not replicable.
Other EEE netbooks seem to have issues with multiple wireless drivers, like in this thread. Perhaps something similar is happening here? My card seems to be using rt2860sta as a driver. I tried blacklisting it, to see if another driver was trying to load instead, but that just negated my wifi altogether. (It's unblacklisted again)
My router is a very reliable Linksys WRT54GL with factory firmware which has never been flaky.
I'm at my wit's end. This netbook will be useless without wifi.
Below is the suggested information for a first post:
Here's lspci (note there is nothing listed as "Wireless Brand" to grep out):
Is there any way to temporarily change the codepage that is used in a terminal?I'm using a couple of internet BBSes and since they're made in the stoneage they can't really handle UTF-8. So I wonder if there's a way to temporarily change the codepage in the terminal to Latin-1? It would also work with a ssh or telnet-client where you can change it. I've looked at putty but it seems to lack cut and paste and support for links which makes it less usefull for me.
The system runs just fine then all of a sudden it "freezes". For example an input box doesn't respond nor can I scroll down the page. But when the system comes out of the freeze 5-15 seconds later, it suddenly does all the input that was used during the freeze. The scroll and letters suddenly show up. I don't loose mouse control and I can do some other system functions but not all of them.

i've got Evolution as an email client in Fedora 12.ve got only one IMAP account configured, which seems to be working OK. However, temporarily it is not sending emails. I write an email and hit send/receive and get error. "Error while sending message" ir seems that it is downloading messages, but not sending. There is a quick, but annoying solution to it: restart Evolution. As soon as it is restarted (close and ope the application) it is working OK for some time.
I just installed openSuse 11.4 on my tablet pc HP Pavillion tx 2000 and then I installed Nvidia driver by Yast, adding before the official repository NVidia.Sometimes, it happens that I can move the cursor mouse but when I click nothing happens, while the keyboard works properly. After more some seconds mouse works again.
