Hi all, Finally, I have installed openvswitch from source to two CentOS hosts: one 6.x and other 7.x. I will do some tests using openvswitch bridges to my KVM machines. One of these tests is to add a wlan0 adapter from comandline but only when this wlan0 is associated with a ssid without assign an IP. Is this posible? Do I nees to add some ebtables like, for example, Debian's wiki

I wonder if there's a way to run a script upon every NetworkManager connection event.

Actually I do a similar thing. I use a VM as my home/office firewall. It works quite well and I would argue it is as secure as your standard firewall based on something like openWRT running on dedicated hardware. I also run a wireless AP in bridged mode to allow local network access on an appliance. There should be no reason that you could not put both on the same physical hardware. As for

I've had some success setting up a crude "screen pops" using Jabber, and am pretty happy with it. But I'd love to have it pop up with the full name and address of the caller. The easiest way to do this is using ServiceObjects "GeoPhone" web service - although it's expensive for small shops (free trial, but $50+/mo after that). The interface would be pretty simple

Hi, I've got a task to have a small number of laptops netboot Linux over WiFi. The kernel is loaded off the USB stick of cource, it's off topic for now. The WPA-supplicant daemon is started early by dracut off initrd. It works. Mostly. The problem is that upon shutdown systemd terminates all the processes FIRST and unmounts filesystems NEXT. Guess what? Upon termination,

I think there's some demand internally for a version of libguestfs where the appliance part actually runs on Windows. So I'm creating this thread to discuss the issue. The reason to want a Windows appliance at all is twofold: (1) better support for NTFS filesystems and Windows-native filesystem features (attributes, volume management etc), and (2) so we can run Windows CMD.EXE commands

The attached patch transparently extends the Builder from util.js to take an object/hash value for the style attribute. The elements of the hash are then used to set the respective properties of the style object. The purpose of this patch is twofold: (1) Make it easier to use the Builder with generated style properties. (2) I''m not sure if assigning a string to element.style is even

Dear, I am using WaveTresh for Haar Wavelets. It works all fine exept when I want to adjust the axis on the wavelet coefficient plot: input: wlh_ponds<-wd(input_waves[,1], family="DaubExPhase",filter.number=1) plot: plot(wlh_ponds,scaling="by.level") My problem is twofold= -I want the original x-axis of the data on that plot, not 1/2 of the axis. This would make

Hi, About half a year ago I installed a stock CentOS 6.0/64bit onto an Intel server to virtualize our Linux fileserver and four WinXP boxes with rdp each. Since recent times I didn't do any upgrades of the server's OS. Now I have CentOS 6.2. After an upgrade I noticed that all virtual cpu name changed to QEMU Virtual CPU version (cpu64-rhel6) The new features were 1) The ability to

Hi, i have two twofold e2image related questions: 1) The man page mentions "cp (1)"'s --sparse=always option. I wonder if there are sparse aware tools which a) display the "real" amount of disk space occupied by a sparse file b) compress sparse files (other than compressing very thightly several GiB of zeros) 2) "E2fsck, mke2fs, etc.

I have a bit of a quandy. I'm working with a data set for which I have sampled sites at a variety of dates. I want to use this data, and get a running average of the sampled values for the current and previous date. I originally thought something like ddply would be ideal for this, however, I cannot break up my data by date, and then apply a function that requires information

Dear All, I have a rather unusual problem. I have a set of data for a class in subsurface processes. From that dataset, I must calculate the slope of the best-fit line (which is the parameter of interest). The problem I have is twofold: 1) for the purposes of the exercise, I must force my best-fit line to go through the origin (0,0), and 2) the line must be linear, even though the data is

Hello, I have been using R/S+ for years and love the software. Still a novice but I can do what i need to.
