Gnetworktester is an application that helps users in testing the quality of a network connection and in sending complaints on that to the network provider. A procedure of testing takes three steps: choosing the network nodes; automatic pinging of those nodes to collect statistics on packet losses, delays, and overall quality; and automatic report writing.
Dandelion is a 3D graph rendering application which can be controlled across a network. Its main purpose is to allow clear network graphs to be rendered in a window, which can be controlled by a separate application or the user. The Dandelion visualization is actually controlled by issuing simple commands to it across the network (although this could all be happening on a single machine). The Dandelion source includes a set of very simple libraries which can be incorporated into other applications and which can be used to send these commands. Libraries are included for C, C#, Java, and Python. The project was developed at Liverpool John Moores University within the PROTECT Centre.
Fing is a command line tool for network and service discovery. It provides you a complete view of any network in a very short time. Its smart discovery automatically detects the network type and uses the best technique to scan it. The best results are achieved on Ethernet networks (including Wireless ones), where Fing is able to detect all network hosts, firewalled ones included. The service discovery feature quickly detects active TCP services on a target host or network. Fing is based on Look@LAN.
Altimate Firewall is a small and easy-to-use firewall, based on a hardened Gentoo system. It has an intuitive and easy-to-use Web interface. The Altimate Firewall uses Shorewall (LAN, WAN, DMZ), OpenVPN, PPTPD, IPSEC, and many more. It includes Avira WebGate and MailGate for safer browsing and for securing your email messages. The network settings can be easily managed by a non-professional.
lldpd is an implementation of IEEE 802.1ab that provides LLDP sending and reception, It supports VLANs and includes an SNMP subagent that can interface to an SNMP agent through the AgentX protocol. LLDP is an industry standard protocol designed to supplant proprietary Link-Layer protocols such as Extreme's EDP (Extreme Discovery Protocol) and CDP (Cisco Discovery Protocol). The goal of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-Layer notifications to adjacent network devices. The daemon is also able to deal with CDP, FDP, SONMP, and EDP protocols. It also handles the LLDP-MED extension.
The Barefoot server is a scalable user-space port bouncer that can be used to forward, or bounce, TCP connections and UDP packets destined for an address on the host on which the Barefoot server runs to any other host or address. To these other hosts, it will appear as if the connection and packets are coming from the machine on which the Barefoot server runs, rather than from the original host. The Barefoot server has support for using proxy protocols on the outgoing side, and can relay incoming traffic out via a SOCKS server or an HTTP proxy supporting the CONNECT command. At the moment, using a proxy for outgoing traffic is only supported for the TCP protocol. The Barefoot server is targeted towards larger sites that need to bounce traffic from many simultaneous clients, while at the same time offering detailed access control, logging, and other features related to controlling the behavior of the traffic and the Barefoot server.
