Software developers using Windows have a fantastic process explorer, made by Mark Russinovich. Linux lacks such a process explorer tool. This projects aims (in the end) to be an equivalent process explorer for Linux.
Goal is to have the same functionality of the Windows process explorer under linux, or less if linux limits us.

Specifically, the deprecated Linux networking commands in question are: arp, ifconfig, iptunnel, iwconfig, nameif, netstat, and route. These programs (except iwconfig) are included in the net-tools package that has been unmaintained for years. The functionality provided by several of these utilities has been reproduced and improved in the new iproute2 suite, primarily by using its new ip command. The iproute2 software code is available from Kernel.org. Iproute2 documentation is available from the Linux Foundation and PolicyRouting.org.
ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Win32 as well.

vous avez constaté que certains de vos processus utilisent des fichiers qui ont été supprimés. Que se passe-t-il si vous voulez les récupérer ?
Chattr permet de sécuriser un fichier ou un répertoire en rendant leur suppression impossible, même avec les droits root.
Chattr est installé par défaut dans les distributions GNU/Linux.
Pour sécuriser un fichier :
sudo chattr +i fichier
Pour supprimer l’attribut i :
sudo chattr -i fichier
Pour sécuriser un répertoire :
sudo chattr +i -R répertoire
Et pour annuler cette action :
sudo chattr -i -R répertoire
