Linux BandWidth tool / News: Recent posts

Waiting for the final 1.0 version in this one you have full name resolution and support for all protocol type.

New option provided ( -w ) to get statistics only of the well-known ports (high ports recognized by IANA are included), instead of every port. This option is very useful when you need to get the real traffic of a network, talking about applications and services. All high ports, used by users to open a remote connection, are ignored.

With this new version, Bandwidth-tool fixes some bugs when exiting with a big amount of traffic. Now, more statistics are shown and the percentage of port used has changed, and now it is calculated based on the total amount of information in what the port is envolved in, so the sum of the three most used ports can be greater than 100. This version is the most stable of all.

It has been a lot of time without improving BandWidth-Tool, but I have been too busy.
Now, in this new release, ARP snifing statistics has been fixed, because the previous version, when in silent mode, stoped counting ARP packets, but not total packets... :-(

And finally, ARP traffic is now more accurate, because now you can see who ask for an IP and the response.

Soon I hope to terminte IP statistics for getting a more efficient information.

This new release includes a new feature for ARP traffic monitoring. This one can be traced and filtered. Actually, when an ARP packet is sniffed, only an "ARP" message appears in the screen. I am working in the next version for showing more information about this kind of packets.

In this new release, the problem with final percentages is fixed. Now, not only the amount of bandwidth used is shown with percentage but the number of packets transmitted too.
Now, a new "-x" option is added that provides the facility of resolving the services names. It is not recomended if there is too many traffic, but there is...

This new release has only a modification in the number of decimals shown in tha bandwidth data at the end of the sniffer session. But the most important improvement is the new RPM package build by Alejandro. Thanks!

This new release includes a new option that let you choose to see between cumulative and single packets size in every line shown in the sniffer. This is very usefull when you are interested in how big are some packets.

This release comes to solve one error in the port statistics. In version 0.8 this data is obtained counting the number of packets per port. This is not correct, because every packet has a different size, so in this new release the statistics are calculated with the total amount of data sent by every port.

Finally, bandwidth-tool can show statistics about ports utilization. At the end of scaning time, three most destination ports used are shown with percentage.

New released of BandWidth-tool, now with a shorter TCP flags visualization mode. Only one letter is used per flag.

All funtionallyties probed and some documentation errors fixed. The next version is trying to include ports descriptions and/or solve the time structure error as described in the manual page. Some features added, and the final version 1 will be released.

Now, this version of bandwidth-tool includes a man page that explain every option of the software, and comes with some examples that illustrate how to use it.

The goal version 1 is near...

Release 0.7 is now correctly avaiable and documented in http://bandwidth-tool.sourceforge.net
System administrators could find it very interesting. Bugs and advices are wellcome by e-mail.
