I need an SSL certificate with a few extra uncommon EKUs (i.e. 1.3.6.1.5.5.8.2.2, "IPSec Intermediate System Usage"). Self-signed certificate is not an option. Does anybody know about any CAs that allow additional EKUs? I contacted Namecheap, Comodo and Godaddy, and all of them replied that they cannot issue one.

I'm trying to execute a certain Python script on USB devices insertion. I need to handle all kinds of USB devices. I'm using a rule like this:
SUBSYSTEMS=="usb", ENV{DEVTYPE}=="usb_device", RUN+="/.../test.py $devpath"
When I insert a USB flash drive, the test.py
script is not executed. If I use a rule like this:
SUBSYSTEM=="usb", RUN+="/.../test.py $devpath"
I catch events for the /devices/pci0000:00/0000:00:02.1/usb1/1-1/1-1.2/1-1.2:1.0
, which is the default configuration of the device; but I don't get any events for /devices/pci0000:00/0000:00:02.1/usb1/1-1/1-1.2
. I do see such events with udevadm monitor
, though. Why does it happen? Am I missing something?
My distro is current Arch Linux.
I have got a laptop running Arch Linux with 2 interfaces: wireless (wlan0
) and ethernet (eth0
). I use wlan0
to access internet (static IP, networking is configured using netcfg), and I connect a second PC to the eth0
.
Now, whenever I start vmware player (v. 4.0.4), it chooses wlan0
to connect its bridged virtual NIC to, but I need it to connect to eth0
(I want my guest machine to be able to talk to the second physical PC on eth0
). So, I disable the wlan0
interface (netcfg -d wireless
) and restart vmware. Now, it connects to eth0
, and everything works fine; I can ping the host PC from the virtual one, and I can ping the virtual PC from the second physical PC connected to eth0
. Then, if I try to reenable the wlan0 interface (netcfg -u wireless
), all of the connectivity between the host and the guest (and between the second physical PC and the guest) gets lost, until I disable wlan0
again. Can someone please give me a hint on what's going on?
I'm currently working with an AMD Opteron-based NUMA system. For the needs of my current project, I'd like to make Linux and all of the system processes to utilize only the CPU0 (and preferably, only one of its cores), leaving all other cores for my own egoistic needs. I know that it will really impact system performance, but it is OK now.
So, I'd like to know if it is possible to achieve at all without messing with the kernel source code. Any links to the up-to-date articles about NUMA and SMP implementation details in Linux will be appreciated, too.
