POSIX Access Control Lists (ACLs) are more fine-grained access rights for files and directories. An ACL consists of entries specifying access permissions on an associated object. ACLs can be configured per user, per group or via the effective rights mask.
These permissions apply to an individual user or a group, and use the same as rwxfound in regular permissions.
For an explanation of rwx, see FilePermissions
Enabling ACLs in the Filesystem
Before beginning to work with ACLs the file system must be mounted with ACLs turned on. This can be done in /etc/fstab for the changes to be permanent.

Transmission Command Line
The BitTorrent protocol can be used to reduce the server and network impact of distributing large files. Rather than downloading a file from a single source server, the BitTorrent protocol allows users to join a « swarm » of hosts to download and upload from each other simultaneously.
Transmission is designed for easy, powerful use. We’ve set the defaults to Just Work and it only takes a few clicks to configure advanced features like watch directories, bad peer blocklists, and the web interface. When Ubuntu chose Transmission as its default BitTorrent client, one of the most-cited reasons was its easy learning curve.
This How-to focuses on CLI (Command Line Interface) and the Web interface
Transmission has been configured to work out of the box on a desktop. Because this how-to is designed for Ubuntu server we need to manually allow remote access. Lire la suite…

Back in the day when we bought OS X on discs, as long as you kept that disc, you always had a bootable installer just in case. Modern, downloadable versions of OS X create a recovery partition on your drive, but it’s always a smart idea to make your own bootable installer drive too.
I recommend making one for Yosemite, on an external hard drive or USB thumb drive, for many of the same reasons I recommend making a bootable Mavericks installer drive: If you want to install Yosemite on multiple Macs, using a bootable installer drive can be more convenient than downloading or copying the entire installer to each computer. If you want to erase the drive on a Mac before installing Yosemite, or start over at any time, you can use a dedicated installer drive to boot that Mac, erase its drive, and then install the OS clean and restore whatever data you need from a backup. And if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.
Macworld also has bootable-install-drive instructions for Mavericks (OS X 10.9), Mountain Lion (OS X 10.8), and Lion (OS X 10.7).
As with previous versions of OS X, it’s not difficult to create a bootable installer drive from the Yosemite installer, though the processes have changed slightly since Mavericks. I show you how, below. Lire la suite…
