How to use the unofficial KNetStats .ebuild file in your Gento installation. 1. Create a directory where the overlay files will be stored, for example: # mkdir -p /usr/local/portage 2. Edit your /etc/make.conf file: # nano -w /etc/make.conf and put the following PORTDIR_OVERLAY setting in it: PORTDIR_OVERLAY=/usr/local/portage 3. Create the directory for KNetStats .ebuild file and download it: # mkdir -p /usr/local/portage/net-misc/knetstats # cd !$ # wget http://ics.p.lodz.pl/~wiktorw/knetstats/knetstats-1.3.ebuild 4. Create the digest (portage internal information) for the package. BTW. It will also download the KNetStats source from the net: # ebuild knetstats-1.3.ebuild digest 5. Install KNetStats: # emerge -av knetstats 6. Run the program. It should be in the KDE menu, in the 'Internet' category. Configure the interfaces you would like to monitor and that's all. Good luck!
