constat 1.2.0 (Default branch)
Image constat is an application that monitors, logs, and reports the activity of network connections present on a system. It reports sent/received traffic information for every live network device, giving you the option of displaying its output in units of kilobytes, megabytes, and gigabytes, along with the number of transmitted packets. It also includes a real time monitoring option based on a timer. Additionally, constat provides the option to view the socket table (local/remote IPs with ports they are binded to) for a specific protocol or all protocols at once. It does not require the X server. License: GNU General Public License (GPL) Changes:
An output only numbers option has been added (-n). A new style of output formatting (transmitted packets are shown on a separate line). An option to use old style formatting (-o). A new log format (same as syslog). The log file has been moved to /var/log/ and renamed to constat.log. The -s option is extended (the 'more' command is automatically executed when viewing all entries; -s= shows the last n entries). The monitoring timer (-m option) default value has changed to 30 seconds. configure has been added. COPYRIGHT has been renamed to COPYING. INSTALL, TODO, and AUTHORS files have been added.Image

NAME

       network_namespaces - overview of Linux network namespaces

DESCRIPTION

       Network namespaces provide isolation of the system resources associated with networking: network devices, IPv4 and IPv6 protocol stacks, IP
       routing tables, firewall rules, the /proc/net directory (which is a symbolic link to /proc/PID/net), the /sys/class/net directory,  various
       files under /proc/sys/net, port numbers (sockets), and so on.

       A physical network device can live in exactly one network namespace.  When a network namespace is freed (i.e., when the last process in the
       namespace terminates), its physical network devices are moved back to the initial network namespace (not to the parent of the process).

       A virtual network (veth(4)) device pair provides a pipe-like abstraction that can be used to create tunnels between network namespaces, and
       can  be	used to create a bridge to a physical network device in another namespace.  When a namespace is freed, the veth(4) devices that it
       contains are destroyed.

       Use of network namespaces requires a kernel that is configured with the CONFIG_NET_NS option.
