|0006697||CentOS-6||NetworkManager||public||2013-10-09 07:33||2013-10-23 07:07|
|Platform||Dell E6420XFR||OS||CentOS||OS Version||6.4|
|Target Version||Fixed in Version|
|Summary||0006697: Segmentation fault when connecting|
|Description||After applying the following updates:|
I can no longer connect to any network (wireless or cable). nm-applet exits with a segmentation fault.
|Steps To Reproduce||Always happens when connecting to a network.|
|Additional Information||I tried removing all network configurations and restarted nm-applet and the computer many times. I finally got it back to work by downgrading to NetworkManager-0.8.1-43.el6.x86_64.|
|Tags||No tags attached.|
|Tried same update on other machine, no problem. The problematic machine is using VirtualBox-4.2-4.2.18_88780_el6-1.x86_64, the other machine not. Maybe a problem with VirtualBox network settings?|
I've had the same problem. I'm running CentOS 6.4 in VirtualBox-4.2.18 (on Windows 7 host).
I updated NetworkManager, NetworkManager-glib and NetworkManager-gnome. After a restart I had no Internet and the icon had gone and I got a segmentation fault every time I tried to start NetworkManager, which was configured to automatically connect.
At first I thought I was in a bit of a catch-22 situation since I couldn't downgrade NetworkManager without access to the Internet, but eventually I realised I could disable the NetworkManager service and set up the connection myself using ifconfig. Then I was able to downgrade NetworkManager, which fixed the problem.
|I might be having a different setup here, but I just changed eth0 to NM-controlled and installed NetworkManager. Prior to that I stoped the network service, and afterwards I started NetworkManager. Pinging 188.8.131.52 didn't work prior to starting NetworkManager, and worked again afterwards. I could also start/open the NetworkManager GUI.|
Well in my case it was exactly the other way around. I have a CentOS 6.4 host and the problem occurs without even starting a virtual machine.
I just thought about VitualBox because I have 3 other machines that don't show this problem and have a very similar setup. Only difference is that they don't have VirtualBox installed.
I've the same issue on a Lenovo R61i with the wireless.
When I run "nm-applet" with my user id, I get an error "Segmentation Fault".
I've run "nm-applet" as root user, no error, it's working.
The difference between user id and root wireless setting is:
- IPv4 Settings Method = Manual
- IPv4 Settings Method = Automatic (DHCP)
kernel release: 2.6.32-358.23.2.el6.x86_64
NetworkManager.x86_64 1:0.8.1-61.el6_4 @updates
NetworkManager-glib.x86_64 1:0.8.1-61.el6_4 @updates
NetworkManager-gnome.x86_64 1:0.8.1-61.el6_4 @updates
NetworkManager-vpnc.x86_64 1:0.8.0-1.git20100411.el6 @epel
|I just retried again as non-root user, killed nm-applet and restarted it (ip is set to manual). At least in a VM i don't experience those issues.|
Confirm the bug on my Thinkpad T61.
NetworkManager successfully connects to WiFi, but upon connecting the Ethernet cable nm-applet segfaults:
** Message: applet now removed from the notification area
** Message: applet now embedded in the notification area
Segmentation fault (core dumped)
$ ps auxw|grep Net
root 4603 0.5 0.0 98156 5868 ? Ssl 12:47 0:00 NetworkManager --pid-file=/var/run/NetworkManager/NetworkManager.pid
Downgrade resolves the problem:
$ cat /etc/redhat-release
CentOS release 6.4 (Final)
$ uname -a
Linux ibm2 2.6.32-358.23.2.el6.x86_64 #1 SMP Wed Oct 16 18:37:12 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
|Please be so kind a report this upstream at https://bugzilla.redhat.com. Once it gets fixed there, CentOS will inherit the fix.|
