Graphical Bandwidth Monitor for Ubuntu

Graphical BW Monitor for Ubuntu

After having shifted to Ubuntu from Windows for quite a long time, I was looking for a no nonsense Bandwidth Monitor. It was during this time that I came across vnStat.

vnStat in the makers word :

vnStat is a network traffic monitor for Linux that keeps a log of daily network traffic for the selected interface(s). vnStat isn’t a packet sniffer. The traffic information is analyzed from the /proc filesystem. That way vnStat can be used even without root permissions. However, at least a 2.2 series kernel is required.

This program is open source/GPL’ed and can be installed either as root or as a single user. Better instructions are included in the README.

So I installed vnStat using

:~$sudo apt-get install vnstat

The first step in using vnStat is to initialize it and configure it to read your Internet bandwidth usage.

RBI’s gift on April Fools Day

Posted by 7sins||2 Comments

Reserve Bank of India

As per a new directive by the Reserve Bank of India, from today 1-April-2009 you won’t need to shell out any extra money to use the ATM of any bank. This has come as a major relief to the common man who get always chnarged for withdrawing cash using ATM and debit cards issued by other banks.

RBI has also allowed the use of ATM, for purposes like balance enquiry, free of any charge.

However, banks can still charge extra for services such as cash withdrawal with the use of credit cards and at ATMs located outside India. Under these circumstances also, some banks plan to expand their ATM network.

BSNL Broadband

Having used BSNL Home 500 plan at one point of my stint with BSNL DataOne I have also faced the usual dilemma; i.e. when to start the downloads during the Happy Hours (aka time period when the downloads are not counted) and then stop it so that i don’t get billed for excessive use and can stay with the limit of 1GB(or was it 1.5GB ?).

It involved using getting up at nights around 2.30AM and starting the downloads. Later that shifted to Task Scheduler of Windows XP then to a scheduler plugin of Azureus and then to the default scheduler of uTorrent.

A n00bs guide to QoS

Posted by 7sins||33 Comments

Quality of Service

QoS or Quality of Service as is defined by Wikipedia states :

In the field of computer networking and other packet-switched telecommunication networks, the traffic engineering term quality of service (QoS) refers to resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. For example, a required bit rate, delay, jitter, packet dropping probability and/or bit error rate may be guaranteed. Quality of service guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications such as voice over IP, online games and IP-TV, since these often require fixed bit rate and are delay sensitive, and in networks where the capacity is a limited resource, for example in cellular data communication.

In layman’s term QoS is the process by which you set some pre-defined rules which determines which data packets are to be allowed first based on their priority level.
