Fedora :: What's The State Of NetworkManager In RHEL
Jul 28, 2011
I've always used the network init service to manage my network interfaces on headless servers and used NetworkManager on desktop installs. Lately it seems that NetworkManger is becoming more and more integrated into network management even on servers. I have a RHEL6 server in my lab that runs NM without any Gnome components installed and I've noticed in Fedora NM becoming more tightly coupled with the system-config-network related services.
I'm asking because this is a "highly connected" server, with two redundant NICs on each of two different networks with a bond interface associating each pair for redundancy. Every time the server reboots it fails to configure its default route correctly. I know how to configure the network using the standard /etc/sysconfig/network and ifcfg-* scripts. Is NM fully integrated with these configuration files?

After updating from 11.3 to 11.4 the networkmanager stopped working for me. When I hover over the KDE NetworkManager icon it says Error: Invalid state. If I click it, it says Network Management disabled and checkboxes (Enable networking and enable wireless - both checked). I already tried removing /var/lib/NetworkManager/NetworkManager.state and restarting the network management (/etc/init.d/network restart). Also reinstalling the NetworkManager package.

This is my last attempt at solving this issue before I have to return to windows as I need to contact family via web. I am unable to connect to the wireless network at home since upgrading to Ubuntu 10 desktop. It worked fine on v9. I reinstalled a full U 10 version but same issue. I am trying to enable wireless in the file mentioned as this seems to solve most posters issues but for some reason when I reboot it loses the update. I've tired logged in as su and sudo i but no joy.

I tried to install KDevelop4, decided I didn't want to use it, and now I am having trouble getting KDevelop3 working again. The only steps to installing kdevelop4 were installing a new version of kdevplatform and then kdevelop itself. I did this:
1) sudo yum remove "kdevplatform* kdevelop*"
2) disable updates and testing repo
3) sudo yum install "kdevelop"
The problem is that there is something wrong with the menus (File, Edit, etc). There are many important items missing, as well as one of them says "No text!". This indicates that this is not the original packaged version with F11 because I used it for a year and it was certainly not like this. Is there a better way to get back to the original version than I showed here?

I'm having trouble with my sound on my new Fedora 12 machine. when I first installed F12 sound was working but it appears that I have messed up some settings somewhere and now alsa is no longer recognizing my sound card (integrated into my ASUS M4A79XTD EVO motherboard)
Code:
$ aplay -l
aplay: device_list:223: no soundcards found...
I'm sure that when I tried to fix it I probably messed it up worse. Is there an easy way to restore all of my sound settings and audio Drivers back to the F12 defaults without losing everything else?

Code:
I have just inserted a new battery. However, there is no settings that show the capacity and current charge time, etc.
When I click the battery icon. All I get is the current percentage.
Is there anything that will give me more details about my battery i.e. capacity, charge rate, time to full charge, etc?

Does anybody here use Foxit Reader 1.1 as PDF viewer? I did since it handles PDF ebook with complex layout better than Evince. No need to mention its smaller size and faster speed than Adobe Reader.
However, it seems that recently it's unable to restore the document state when the file was closed. I do not know which part goes run right now but quite sure in the late August it works well. It always jumped to the position when I stopped last time. Now it simply starts from the the first page. :-)
I looked through the Foxit Reader forum and found none similar problems reported. I posted here to see whether it is a Fedora specific problem or generalised one.

I'm seeing weirdness with Scottrade's main screen with Firefox (not the real-time streaming quotes app). It seems after a few minutes, whether idling or otherwise, Firefox gets into a state where nothing on the Scottrade page is clickable. Firefox menus still work as do other tabs so Firefox itself is still alive. It's as if a timer fires inside Firefox that renders the Scottrade page inert. Manually reloading the page temporarily fixes the problem. This is the only website where I've encountered this. It's particularly annoying when you're in the middle of placing a trade order and the page suddenly goes dead when you're about to submit.
System: Fedora 11 x86-64 Firefox 3.5.6 (x86-64) from Fedora Update
I thought maybe this was a problem specific to Fedora's Firefox build so I installed the FF 3.5.6 and 3.6.0 i386 from a tarball direct from Mozilla. Same results. I'd be inclined to call this a Firefox bug were it not for the fact that I do not see this behavior on my ancient Fedora 4 machine running Firefox 3.5.6 installed from the same tarball.

F15 x86_64
I can start this from the command line and it shows no errors.
httpd -t --- syntax ok.
no entry in the httpd error logs.
chkconfig reports it as on.
service --status-all shows this --
httpd.service - LSB: start and stop Apache HTTP Server
Loaded: loaded (/etc/rc.d/init.d/httpd)
Active: failed since Wed, 01 Jun 2011 07:06:18 +0100; 58min ago

After a reinstall I finally caught this in /var/log/messages
systemd[1]: Unit httpd.service entered failed state
The httpd.service file does not exist on the system. Where can I get a copy?

I installed F9 for a friend. She wasn't getting any sound. I ran aplay -l, but got no sound card listed. I ran lspci -v, but got no sound card listed. However,the output of lspci -v said the computer had a particular motherboard. I Googled for it and was told it had an onboard sound card. That led me to the package called realtek-linux-audiopack-4.06a, which I installed. It included an installation script, which I ran.
The script didn't work to compile various files it was supposed to, but it did work to delete various files from my friend's system. Here are the bits of the script that removed files:
echo "Remove old sound driver"
if [ -d /lib/modules/$KERNEL_VER/kernel/sound ]; then
rm -rf /lib/modules/$KERNEL_VER/kernel/sound/pci > /dev/null 2>&1
[code]....
In the result, the failure of the compilation didn't matter, because lspci -v lied. She didn't have the motherboard shown, but a different one without an onboard sound card. Of the files deleted by the script.
I was able to reinstall libasound.so.2 and libasound.so.2.0.0, but I haven't yet tried to reinstall the other ones deleted by the script. Now, I want her to buy a sound card, but I'm afraid it won't work unless all the deleted files are reinstalled. I'm looking for guidance as to how I can reinstall the files deleted by the bits of the script I set out above, without completely reinstalling Fedora.

How do I check the state and health of the laptop battery. In Ubuntu it was just a simple task of clicking on the battery icon on the task bar and your info would come up. With Fedora 13 nothing happens..

F12 64 bit machine, connects to a Windows share to which a HP PSC 1210 is connected through a USB connection. Printer is set to share, nicknamed "Asterix". When the printer is set up through F12, I select under Network printer "Windows printer via Samba". I browse, find the printer, and click verify. The printer is accessible. Then I finish the installation, ordering a test print. Here the strange things start happening (attached some screenshots to back the story up).
1) No error messages appear that I can find. No cups-errors, no other errors pop up on the F12 machine. The print appears and disappears from the "Document Print Status (Asterix)" window. Only on the Printer Properties page do I see something strange: Printer state: Idle - procession page 2.
2) In the Windows machine, I also can't find any error messages. The print appears in the Printer list, and stays there. The printer comes to life, checks its cartridges, rolls some wheels, and then decides to do nothing more. When I select the print and click on Properties, the default priority is 1, but when I move it up to 99, nothing changes. The only strange thing here is, that the document, according to the Windoze machine, has 0 pages, yet is some 20MB.
And nothing ever happens.
Things I think it's not:
Firewall issue. The print obviously slips through to the other end.
Faulty driver issue. Directly from the Windoze machine, and if plugged into the USB of the F12 machine, does it print perfectly fine.

I am using Fedora 12 with HP 1020 Laser Jet. Plugged printer in and installed it. Now it doesn't want to print, it gives me a printer state message: /usr/lib/cups/filter/hpcups failed.
I have tried to reinstall hplip but it is the same.

I have no problems seeing the networks available and connecting to a network in KDE. But there is no network manager in GNOME. I might have messed up with the settings earlier. What I can do though is run knetwork manager every time I start up (or add it to start up programs). But that opens up the KDE wallet which would rather avoid.I am thinking I need to install something related to NetowrkManager.

I just upgraded (as a fresh install) to Fedora 13. In so doing I kept the old /home partition. My NetwokrManager Applet is missing from the top bar. But if I login instead as a different user, then it is there. When I did the install, I had to create a (new) user as part of the process. The old passwd file had two users, one called admin, and the other myself. I logged in initially as the new user, and created the admin user keeping the same home directory, user ID and group ID. I then logged out, logged in again as admin, and removed the new user. I then added myself as a user keeping the same home directory, and user and group IDs.. For some reason admin has the applet but I don't. I also don't see how to add it except as a custom laucher using nm-applet, and that didn't seem to work.

if the NetworkManager uses wpa_supplicant? I normally dont use NetworkManager and decided to try it. I started it and tried it out and it works with WEP and WPA! I cant figure out why using the iwconfig command is not working by itself for WEP. WPA working with NetworkManager is just a bonus though.

My wireless device is an Intel Ultimate N WiFi Link 5300, driver is iwl4965. Post-suspend I see exactly the same messages as in that Ubuntu report. Restarting NM does not help.Is there a way to lengthen to timeout or kick the device in to life some other way?

I'm an inordinate amount of trouble getting F15 to run without NetworkManager. If I boot with the NetworkManager service enabled, my NIC presents as expected at /dev/eth0 (I'm using biosdevname=0). However, when I stop the NetworkManager service, /dev/eth0 disappears from the filesystem.If I boot without NetworkManager enabled, /dev/eth0 is never created. Reviewing dmesg, udev is loading an ethernet driver.

hi, first i'd like to say that i'm totally new to linux, i was allways using windows.
as i was allways unable to install a good and stable ssh-server on windows, i thought it is time to change to linux. i was able to set up and configure a ssh-server on debian but found out, that fedora 15 looks more userfriendly in first place for me. but now i unfortunately experience problems..
the ssh server was already installed, i changed the service setting to that it starts automatically but after i succesfully connected to the LAN, i cannot access the shh via putty for instance. when i type "service sshd status" it says beside other things: active (running). but when i look at the /var/log/messages, it says those two lines:
sshd.service: main process exited, code=exited, status=255
Unit sshd.service entered failed state.
i searched on google without success, the only thing i found was that someone had the same problem with a bad sshd_config file, but i'm pretty sure that everything is alright with my config-file (i checked it several times).
beside this i cant login on the gui, after the firefox update (??) it always says: a problem has occured and the system can't recover bla bla... so i can only use fedora right now commandline-based.. but with this problem i will deal later on...

I loaded F10 up on my laptop a few nights back. NetworkManager connects via Ethernet just fine. It will also connect wirelessly, but only when security is disabled. I've been using 128-bit WEP.
When I try to connect using security, this is what appears in the log:
Code:
Jan 29 21:07:17 localhost NetworkManager: <info> Activation (wlan0) Stage 1 of 5 (Device Prepare) complete.
Jan 29 21:07:17 localhost NetworkManager: <info> Activation (wlan0) Stage 2 of 5 (Device Configure) starting...

after fiddling around with compiz-fusion and KDE, my network suddenly disappeared. I looked in the package manager and apparently I don't have the gnome applet for networkmanager...but everything else I seem to have (the git version not svc or w/e) Anyone know if installing the applet will let me choose my wireless network and connect to it? Right now I think so, but what I have to do is boot into windows, find the package on the web and download it, then boot into fedora and install it
where I can find the fedora 10 networkmanager-gnome package (git version for x86_64)? I looked around and found the svc version and a git version for i386, but my OS is x86_64 and I couldn't find any git versions of it for 64-bit fedora's. btw, I have no idea what git and svc mean, but when I tried to install the svc version, it told me I had to install svc versions for all the other networkmanager packages...

I recently installed F10 x86_64 on my Lenovo T61 laptop, and while I'm quite pleased with F10, I am having a difficult time with my wireless card. I spent most of yesterday searching for a solution, but none have presented themselves. Scenario: I am trying to connect to a HIDDEN SSID with NO ENCRYPTION (work Wifi, don't ask) using network-manager and its associated applet.
Symptoms: I left-click on NetworkManager, select "Connect to Hidden Wireless Network", enter my information, NetworkManager does a few things, and finally I'm told that NetworkManager cannot connect to my network.
