Update 2: I added a tunnel setup that I got from a helpful person on pulseaudio's IRC channel. It may have taken me years, but finally I got around to implementing this and it works, easy.

L'utilisation de volumes logiques remplace en quelque sorte le partitionnement des disques. C'est un système beaucoup plus souple, qui permet par exemple de diminuer la taille d'un système de fichier pour pouvoir en agrandir un autre, sans se préoccuper de leur emplacement sur le disque. eXo Platform Enterprise Virtual Machines.

Activating and Deactivating Volume Groups When you create a volume group it is, by default, activated. This means that the logical volumes in that group are accessible and subject to change. There are various circumstances for which you you need to make a volume group inactive and thus unknown to the kernel. To deactivate or activate a volume group, use the -a (--available) argument of the vgchange command. The following example deactivates the volume group my_volume_group. Installation.

Remote Packet Capture for iOS devices

In this post I want to highlight another useful network debugging tool which allows you capture network traffic from an iOS device. Remote Virtual Interfaces As with the Network Link Conditioner you need to use a host Mac computer to perform remote packet capture of an iOS device. The only other requirement is that the device be connected to the host computer via USB. The basic technique is to create an OS X remote virtual network interface that represents the remote network stack of the iOS device. The steps to get the virtual network interface up and running are as follows: Plug your iOS device into the USB port of your Mac.Use the Xcode organizer to obtain the UDID of the device (the value you want is named Identifier):

Isohybrid - Syslinux Wiki. ISO 9660 filesystems which are created by the mkisofs command in the article about ISOLINUX will boot via BIOS or UEFI firmware only from optical media like CD, DVD, or BD. The isohybrid feature enhances such filesystems by a Master Boot Record (MBR) for booting via BIOS from disk storage devices like USB flash drives. ISOLINUX provides two alternative programs to apply this feature on image files or block devices with ISO 9660 filesystems: isohybrid.pl needs a perl interpreter and is supposed to be widely portable. isohybrid from utils/isohybrid.c needs to be compiled once for a particular operating system and hardware architecture. Then it is usable without other preconditions. Meanwhile there is an additional isohybrid feature for UEFI. Both isohybrid programs contain MBR code matching the same version of the ISOLINUX bootloader file, "isolinux.bin". The basic usage is simple.

Isohybrid output.iso. Creating a bootable USB drive from an ISO image. What's an ISO? Why would you want to write an ISO to a USB drive? Typically one of two reasons: Compatibility: You want to boot the ISO on a physical computer that doesn't have a CD drive.Originally ISO files were intended to be burned to physical CDROM discs. Unfortunately while most virtualization software (e.g., KVM, VMWare, VirtualBox) has support for inserting ISO images into "virtual" CD readers, physical CD readers are a dying breed.

Convenience: USB flash drives are smaller, faster, rewriteable and more robust than a clumsy, flat, scratchable CD. 4 outils pour créer une clé USB bootable avec un fichier ISO.
