System - Network (90)

NetConnectChoose lets you choose the default Internet connection for a given application. This is useful for security/speed (like using wired instead of wireless), to prevent overload, or save high bandwidth only for critical applications. Note that each connection must come from a different network adapter.

The program also displays extensive information about every active network/Internet connection, including network adapter name, MAC Address, Name Servers, MTU, Interface Speed, current incoming/outgoing data speed, number of received/sent packets, received/sent bytes, and more.

Firewall App Blocker simplifies program management settings for the Windows Firewall. The program makes it easy to block or allow program and process access to the network. Supports batch operations for multiple programs or processes, drag-and-drop, inbound rules tab (for servers), and disabling/enabling Internet access.

By default, the program manages listed processes, but can also be set to allow ONLY those processes shown, or "whitelist" mode.

NetworkCountersWatch displays system counters for every network interface on your system, which includes the numbers of incoming/outgoing bytes, incoming/outgoing and broadcast packets and more. You can also initialize all counters to zero at any time in order to watch the network counters for specific event. It also calculates and displays the current download and upload speed on your network interface.

WhoIsConnectedSniffer is a network discovery tool that listens to network packets on your network adapter using a capture driver (WinpCap or MS network monitor) and accumulates a list of computer and devices currently connected to your network. WhoIsConnectedSniffer uses various protocols to detect the computers connected to your network, including ARP, UDP, DHCP, mDNS and BROWSER.

For every detected computer or device, the following information is displayed: (Some of the fields might be empty if the information cannot be found inside the packets) IP Address, MAC Address, name of the device/computer, description, Operating System, Network Adapter Company, IPv6 Address.

After collecting the connected computers/devices information, you can easily export the list to tab-delimited/comma-delimited/xml/html file.

WhoisThisDomain is a domain registration lookup utility that allows you to easily get information about a registered domain. It automatically connect to the right WHOIS server, according to the top-level domain name and retrieve the WHOIS record of the domain.

It support both generic domains and country code domains.

WifiChannelMonitor captures Wi-Fi traffic on the channel you choose using Microsoft Network Monitor capture driver in monitor mode and displays extensive information about access points and the Wi-Fi clients connected to them. The program also allows you to view the information about wireless clients that are not connected to any access points, including the list of SSIDs (network names) that they are trying to connect.

For every access point, the following information is displayed: SSID, MAC Address, Device Manufacturer, PHY Type, Channel, RSSI, Security, Beacons Count, Probe Responses Count, Data Bytes, Retransmitted Data Bytes and more. Each client lists MAC Address, Device Manufacturer, SSID list that the client tries to connect, Sent Data Bytes, Received Data Bytes, Probe Requests Count etc.

TCPView gives a detailed listing of all endpoints on your system, including both TCP and UDP for local and remote addresses and state of TCP connections. On Windows NT, 2000 and XP, TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows.

Also available from PortableaApps.

TurnedOnTimesView analyses the Windows event log, detecting the time ranges when your computer was turned on. For those time frames, startup/shutdown time, duration, shutdown reason, type and process, as well as shutdown code are all displayed.

The program works on your local computer as well as from remote computer on your network if you have privileges to view the Windows event log remotely. Although primarily for system administrators, it can also help track down system issues and in testing.

NetSetMan is a network settings manager that helps you switch between 6 different, visually structured network profiles. This includes IP address, subnet mask, default gateway, preferred/alternate DNS server, computer name, workgroup, DNS domain, WINS server, default printer and run scripts.

Although intended for mobile users who need settings for home, office, wireless etc., this software can also be useful for advanced network configuration and diagnostics.
