BIND 9 is an implementation of the Domain Name System (DNS) protocols. named daemon is an Internet Domain Name Server for UNIX like operating systems. Dynamic update messages may be used to update records in a master zone on a nameserver. When named receives a specially crafted dynamic update message an internal assertion check is triggered which causes named to exit. An attacker which can send DNS requests to a nameserver can cause it to exit, thus creating a Denial of Service situation. configuring named to ignore dynamic updates is NOT sufficient to protect it from this vulnerability. This exploit is public. Please upgrade immediately.
Look like combined company will give a tough time to both IBM and HP.
Sun Microsystems and Oracle Corporation announced yesterday that they have entered into a definitive agreement under which Oracle will acquire Sun common stock for a total of $7.4 billion or $5.6 billion net of Sun’s cash and debt.
Virtualization is the latest buzz word. You may wonder computers are getting cheaper every day, why should I care and why should I use virtualization? Virtualization is a broad term that refers to the abstraction of computer resources such as:
- Platform Virtualization
- Resource Virtualization
- Storage Virtualization
- Network Virtualization
- Desktop Virtualization
This article describes why you need virtualization and list commonly used FOSS and proprietary Linux virtualization software.
Linux and other Unix-like operating systems use the term “swap” to describe both the act of moving memory pages between RAM and disk, and the region of a disk the pages are stored on. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?
Finally, Adobe has released 64 bit preview version of its most popular flash player today for Linux / Solaris UNIX operating system. There is no Windows or Mac 64 bit version exists but Linux / UNIX is the first OS to get it. Indeed a good news; now we have both Java and Flash plyaer for 64 bit platforms. No need to use nspluginwrapper.
It’s about time someone wrote this article. I know the headline is a little bit provoking. But when you think about some comments from Linux proponents you could think so.
