A hard link is actually nothing more than a regular directory entry, which in turn can be seen as a pointer to the actual file’s data on the disk. The cool thing about hard-links is that a file can be stored once on the disk, and be linked to multiple times, from different locations/entries, without requiring to allocate extra disk space for each file instance.

But then a question arises: Given a specific file on disk, how can someone know whether it is linked to by other directory entries or not? This can be easily answered using the ls command:

giannis@zandloper:/etc$ ls -l passwd
-rw-r--r-- 1 root root 1402 2008-03-30 17:49 passwd
;

Do you ever wonder what is this small number between the file permissions and the owner in the output of ls’s long listing format (its value is usually “1″ for files, or “2″ for directories)? This number is actually the link-count of the file, when referring to a file, or the number of contained directory entries, when referring to a directory (including the . and .. entries).

Garry’s mod is one of the most sold games for Linux on Steam, so I’ve decided to publish this review of the game, first published on devtome.com 

Garry’s Mod, developed by Facepunch is without a doubt one of the most enjoyable and hilarious games that I have ever played. Out of the box, the game is perhaps one of the ultimate sandbox games available anywhere. You spawn in the middle of an open area that you choose and you can spawn in just about any item or NPC that you can think of. This game is also probably one of the best physics simulators available. The entire game revolves around physics. In this game you are able to do whatever you heart desires and although I say that with a lot of different games, I truly mean it with Garry’s Mod. Whatever you want. If you want to build an airplane out of a bathtub and some planks of wood, then be my guest. You can simply spawn in the materials that you want and then use tools to “weld” them together. Using weight tools you can make these items very light, which will allow them to become airborne. This game definitely deserves lots of praise.

In previous posts we’ve seen how to Enable automatic security update in Debian/Ubuntu and in Red hat enterprise or Centos 6, recently I’ve started to work with the new Red Hat Enterprise 7 and I’ve noticed that there are some interesting changes in the way this system can be set to auto update.

An example ?

In Red Hat/Centos 6 you could not set which kind of update you’d like to do, so you could just decide to update for any kind of update (feature,bug or security) or nothing at all, this has changed and now we can fine grain which kind of updates we want to do on our servers.

The SCP protocol is a network protocol, based on the BSD RCP protocol, which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and utilizes the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit. A client can send (upload) files to a server, optionally including their basic attributes (permissions, timestamps). Clients can also request files or directories from a server (download). SCP runs over TCP port 22 by default. Like RCP, there is no RFC that defines the specifics of the protocol.

SCP is an awesome tool. Learn it, Love it, Use it….
