Network Analyzer

The Network Analyzer is a network monitoring and troubleshooting tool built in C# for use with the Windows Operating System. It downloads as a single EXE for quick launch on any computer and while maintaining portability.

Current Features

Note that for major features, a small "i" is displayed next to the feature which offers a brief explanation of the feature and any user input limitations if any exist

Home Screen

• Provides basic device information
• Provides general connectivity information for IPv4, IPv6 and DNS
• Provides a changelog for the latest release

Latency Monitor

• Takes in up to five targets (IPv4 Address or DNS Name) and monitors their latency
• Keeps track of the lowest, highest and average latencies returned during the session
• Tracks how many packets were lost during the session for each target
• Reports on whether the connection was UP, UNSTABLE or DOWN during the session
• Ability to hover over a DNS name in the target list and view the IP Address the DNS name resolves to

Status Breakdown

The status indicates the condition of the ICMP packets returned from the user-defined targets and is calculated from a pool of up to 60 packets at any given time

• The status of UP is used when a target has had fewer than 12% of the packets returned as anything other than Success from the Ping Response
• The status of UNSTABLE is used when the target has had between 12% and 50% of its packets returned as anything other than Success from the Ping Response
• The status of DOWN is used when the target has had 50% or more of its packets returned as anything other than Success from the Ping Response

User Targets Mode

• Allows the user to enter up to five targets to monitor and returns latency information accordingly

Traceroute Mode

• Allows the user to enter a single target with a TTL and generate a traceroute for that target which is then monitored within the Latency Monitor for every hop of the traceroute

IP Scanner

• Scans the network for devices and returns information
• Supports both auto and manual scanning of networks
• Information returned from the scan: DNS Name, IP Address, MAC Address and NIC Manufacturer
• RDP, SSH and SMB functionality available for devices located in the scan

Scanning Breakdown

• Auto Mode

  • Determine the subnets to scan for devices based upon the active IP Addresses tied to the devices Network Interface Cards
  • Filters out APIPA, Link-Local and IPv6 addresses from the pool so as to provide the most accurate info with the least clutter

• Manual Mode

  • The subnets to scan are determined by the user input
  • Supported input includes the following:
  • IP Address followed by CIDR notation (e.g. 172.30.1.1/24)
  • IP Address followed by a Subnet Mask (e.g. 172.30.1.1 255.255.255.0)
  • IP Range separated by a hyphen (e.g. 172.30.1.1 - 172.30.1.57)

Active Device Features

• These features will be displayed for a device if the port is available on the device
• Note that the port being available does not guarantee the connection can be established
• Supports the following functionality for active devices:
  • RDP [attempts a connection using the Windows Rremote Desktop client]
  • SSH [attempts a connection via a Windows PowerShell console]
  • SMB [opens Windows File Explorer to the target destination and displays any available file shares]

System Tray Accessibility

• Allows for the Network Analyzer to be minimized while running so as to not disturb the user while active
