Restbed is a comprehensive and consistent programming model for building applications that require seamless and secure communication over HTTP.

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

czmq provides bindings for the ØMQ core API that hides the differences between different versions of ØMQ.

LibNice is a library that implements the Interactive Connectivity Establishment (ICE) standard (RFC 5245 & RFC 8445). It provides a GLib-based library, libnice, as well as GStreamer elements to use it.

This package provides a command-line client (gandi) to buy, manage, and delete Internet resources from Gandi.net such as domain names, virtual machines, and certificates.

libyang is a YANG data modelling language parser and toolkit written (and providing API) in C. Current implementation covers YANG 1.0 (RFC 6020) as well as YANG 1.1 (RFC 7950).

The lksctp-tools project provides a user-space library for SCTP (libsctp) and C language header files (netinet/sctp.h) for accessing SCTP-specific APIs not provided by the standard sockets. It also includes some SCTP-related helper utilities.

Miredo is an implementation (client, relay, server) of the Teredo specification, which provides IPv6 Internet connectivity to IPv6 enabled hosts residing in IPv4-only networks, even when they are behind a NAT device.

Phantomsocks is an Internet censorship circumvention tool based on the desync technique, which was introduced in the 2017 paper Your State is Not Mine: A Closer Look at Evading Stateful Internet Censorship.

Further information on the usage could be found on the Wikibooks page Phantomsocks.

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.

Net::DNS is the Perl Interface to the Domain Name System.

Net::DNS::Resolver::Programmable is a programmable DNS resolver for offline emulation of DNS.

Net::Patricia does IP address lookups quickly in Perl.

dnstracer determines where a given Domain Name Server (DNS) gets its information from, and follows the chain of DNS servers back to the servers which know the data.

The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialized messaging middle-ware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.

httping measures how long it takes to connect to a web server, send an HTTP(S) request, and receive the reply headers. It is somewhat similar to ping, but can be used even in cases where ICMP traffic is blocked by firewalls or when you want to monitor the response time of the actual web application stack itself.

This library provides methods for using the stream control transmission protocol (SCTP) in a Go application.

Iodine tunnels IPv4 data through a DNS server. This can be useful in different situations where internet access is firewalled, but DNS queries are allowed. The bandwidth is asymmetrical, with limited upstream and up to 1 Mbit/s downstream.

mbuffer is a tool for buffering data streams with a large set of features:

• direct support for TCP based network targets (IPv4 and IPv6)

• ability to send to multiple targets in parallel (distribution mode)

• support for multiple volumes

• I/O rate limitation

• high/low watermark based restart criteria

• configurable buffer size

• on the fly MD5 hash calculation

• highly efficient, multi-threaded implementation

UsrSCTP is a portable SCTP userland stack. SCTP is a message oriented, reliable transport protocol with direct support for multihoming that runs on top of IP or UDP, and supports both v4 and v6 versions.

NetHogs is a small 'net top' tool for Linux. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process.

NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.

SRT is a transport technology that optimizes streaming performance across unpredictable networks, such as the Internet.

whois searches for an object in a WHOIS (RFC 3912) database. It is commonly used to look up the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. It can automatically select the appropriate server for most queries.

For historical reasons, this package also includes mkpasswd, which encrypts passwords using crypt(3) and is unrelated to the Expect command of the same name.

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.
