While packages are available for most of the platforms, installation is fairly straight forward. Download, compile and install as follows:
I did the installation in Debian but should be the same for most of the platforms
debian4R2Base:/etc# wget http://www.gropp.org/bwm-ng/bwm-ng-0.6.tar.gz
Untar & Unzip
debian4R2Base:/etc# tar -zxvf bwm-ng-0.6.tar.gz
Compile & Install
debian4R2Base:/etc# cd bwm-ng-0.6
debian4R2Base:~/bwm-ng-0.6# make && make install
You have to install “libstatgrab”, if you choose to use it
debian4R2Base:~/bwm-ng-0.6# aptitude install libstatgrab6
That completes the installation.
In debian, if you want to use the aptitude package manager to install then you need to install from the unstable source http://packages.debian.org/unstable/net/bwm-ng as this contains the latest version with disk I/O support.
If disk I/O is not required then can install bwm-ng 0.5 from the stable sources
debian4R2Base:~/bwm-ng-0.6# aptitude install bwm-ng
Once installed simply running “bwm-ng” will default to Network stats on all interfaces. You can use bwm-ng for all options.
For stats on all network Interfaces
For stats on Select Network Interface
debian4R2Base:~/bwm-ng-0.6# bwm-ng -I eth0
where eth0 is the network interface
For stats on Disk I/O
debian4R2Base:~/bwm-ng-0.6# bwm-ng -i disk
(Reads from /proc/diskstat)
In Windows, simply download, unzip the file and run the EXE file. For more information, visit the homepage here
