Bandwidth Monitor NG is a small and simple console based live network and disk I/O bandwidth monitor.

Netdiscover is a network address discovery tool developed mainly for wireless networks without a DHCP server. It also works on hub/switched networks. It is based on ARP packets, it will send ARP requests and sniff for replies.

nm-tray is a network connection management tool (NetworkManager front-end) with an information icon residing in the system tray. Unlike nm-applet, which is part of GNOME, this application is desktop-unaware.

Proxychains-ng is a preloader which hooks calls to sockets in dynamically linked programs and redirects them through one or more SOCKS or HTTP proxies.

IFStatus is a simple, easy-to-use program for displaying commonly needed/wanted real-time traffic statistics of multiple network interfaces, with a simple and efficient view on the command line. It is intended as a substitute for the PPPStatus and EthStatus projects.

With this package you can monitor and filter incoming requests for network services. It includes a library which may be used by daemons to transparently check connection attempts against an access control list.

ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP. The primary feature it provides is optional reliable, in-order delivery of packets. ENet omits certain higher level networking features such as authentication, server discovery, encryption, or other similar tasks that are particularly application specific so that the library remains flexible, portable, and easily embeddable.

libnatpmp is a portable and asynchronous implementation of the Network Address Translation - Port Mapping Protocol (NAT-PMP) written in the C programming language.

Slurm is a network load monitor. It shows real-time traffic statistics from any network device in any of three ASCII graph formats.

This package provides a modern, but Linux-specific implementation of the traceroute command that can be used to follow the route taken by packets on an IP network on their way to a given host. It utilizes the IP protocol's time to live (TTL) field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to the host. Compared to other implementations, this traceroute command allows some traces for unprivileged users.

parprouted is a daemon for transparent IP (Layer 3) proxy ARP bridging. Unlike standard bridging, proxy ARP bridging can bridge Ethernet networks behind wireless nodes. Normal layer 2 bridging does not work between wireless nodes because wireless does not know about MAC addresses used in the wired Ethernet networks. This daemon can also be useful for making transparent firewalls.

Tool to send a magic packet to wake another host on the network. This must be enabled on the target host, usually in the BIOS.

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages.

mtr combines the functionality of the traceroute and ping programs in a single network diagnostic tool. mtr can use several network protocols to detect intermediate routers (or hops) between the local host and a user-specified destination. It then continually measures the response time and packet loss at each hop, and displays the results in real time.

This package provides a daemon that snitches on programs making outbound connections. OpenSnitch is an application-level firewall that gives you granular control over outbound network connections on your system. It monitors application activity and prompts you to allow or deny connections on a per-application basis whenever a new outbound connection is attempted.

This program helps automate the creation and maintenance of BGP routing filters used for peering through Internet exchanges.

It generates prefix lists, (extended) access lists, policy-statement terms, and AS paths from data in the IRR, including the RADB operated by the Merit Network at the University of Michigan.

The filters can be aggregated and exported in the most common formats.

Wireless networking GUI front-end for iwd, with supported functionality similar to that of iwctl. Features include viewing and connecting to available networks, managing known networks, provisioning new networks via WPS or Wi-Fi Easy Connect, and an indicator icon displaying connection status and signal strength.

Netperf is a benchmark that can be used to measure the performance of many different types of networking. It provides tests for both unidirectional throughput, and end-to-end latency. The environments currently measurable by netperf include: TCP and UDP via BSD Sockets for both IPv4 and IPv6, DLPI, Unix Domain Sockets, SCTP for both IPv4 and IPv6.

fping is a ping-like program which uses ICMP echo requests to determine if a target host is responding.

fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next target in a round-robin fashion.

This package provides CAN utilities in the following areas:

• Basic tools to display, record, generate and replay CAN traffic

• CAN access via IP sockets

• CAN in-kernel gateway configuration

• CAN bus measurement and testing

• ISO-TP (ISO15765-2:2016 - this means messages with a body larger than eight bytes) tools

• Log file converters

• Serial Line Discipline configuration for slcan driver

RESTinio is a header-only C++14 library that gives you an embedded HTTP/Websocket server. It is based on standalone version of ASIO and targeted primarily for asynchronous processing of HTTP-requests.

PageKite implements a tunneled reverse proxy which makes it easy to make a service (such as an HTTP or SSH server) on localhost visible to the wider Internet, even behind NAT or restrictive firewalls. A managed front-end relay service is available at https://pagekite.net/, or you can run your own.

Net::CIDR::Lite merges IPv4 or IPv6 CIDR addresses.

The Link Layer Discovery Protocol (LLDP) is an industry standard protocol designed to supplant proprietary Link-Layer protocols such as EDP or CDP. The goal of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-Layer notifications to adjacent network devices. lldpd is an implementation of LLDP. It also supports some proprietary protocols.
