What is SIP

The Basics

The Session Initiation Protocol (SIP) is a signalling protocol used for establishing sessions in an IP network. A session could be a simple two-way telephone call or it could be a collaborative multi-media conference session. The ability to establish these sessions means that a host of innovative services become possible, such as voice-enriched e-commerce, web page click-to-dial, Instant Messaging with buddy lists, and IP Centrex services.

Over the last couple of years, the Voice over IP community has adopted SIP as its protocol of choice for signalling. SIP is an RFC standard (RFC 3261) from the Internet Engineering Task Force (IETF), the body responsible for administering and developing the mechanisms that comprise the Internet. SIP is still evolving and being extended as technology matures and SIP products are socialised in the marketplace.

Rectifying “Either the superblock or the partition table is likely to be corrupt”Error in Linux

In a Linux computer, partition table and superblock are two most important data structures. The superblock keeps record of the file system characteristics including its size, empty and filled block, location and size of Inode tables, block size and status. The partition tables stores all required information about hard drive primary partitions. When any of these data structure gets damaged, hard drive become inaccessible and all of the stored data can not be accessed. This behavior of Linux operating system results into critical data loss situations. At this point, to retrieve data your data from affected drive, you are required to carry out Linux Data Recovery using appropriate solutions.

In a practical scenario, when you run fsck on Linux hard drive to detect and fix file system errors, you might come across below given error message:

“The file system size (according to the superblock) is xxx

The physical size of the device is xxx

Resolving Ext3 Error: No journal on filesystem

Ext3 is a journaled file system and maintains a journal file to prevent instances of metadata corruption due to unexpected power outage. Due to its wide testing base and relative simplicity, the file system is considered to be safer than its counterparts. But it is not completely immune to crashes. At times, when using a Ext3 formatted drive, you might receive errors suggesting that system doesn't find any journal on the file system. As a solution, you might be compelled to reinstall the system. In such situations, you need to check the status of your backup that should be valid and completely updated to restore information from. But if you observe any backup related issues, Linux Recovery utilities should be used.

For an instance, while attempting to mount your Linux based hard drive, you might come across the similar error message:

“ext3: no journal on filesystem”

WineXS – Simple graphical environment to configure Wine

Wine is an Open Source implementation of the Windows API on top of X and Unix.Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code,
however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, and Solaris.

WineXS allows you to easily configure Wine by installing and removing software, editing the registry,managing files, and more.

Google Gears For 64bit Linux & Firefox

Google has a fantastic little add on called Gears, unfortunately there is no support from Google to install Google Gears on your 64bit Linux machine. However, the good news is that Google was kind enough to provide Gears as open source! Users of Gmail, Wordpress, Greasemonkey and Wikipedia can greatly benefit from this little gem. Gears is a extension that allows you to take commonly used web applications off line. Storing essential components locally on your computer, making them as quick as can be. More on Google Gears can be found here.

There have been a few different people to release a 64bit compatible Gears add on, however some have issues and some don't. So far, I've found the best one to be written by a nice guy who calls himself Niels. Niels of Niels` blog has a link here on his blog.
