    PingMon

    PingMon

    Ping monitoring tool (32 Bit) for any Windows System (x86 or x64)

    This is a ping monitoring tool for almost any Windows System (tested on Win 98*-10 and Server 2003-2016) and it runs on Linux via WINE either*. No .NET is needed. This is a 32bit app and will work on x86 and x64 architectures. Adjustable and easy to use. And you can choose if you want it to create RAW packets instead of using Windows icmp.dll resources. Usage examples: PingMon.exe HOST1 HOST2 Will open 2 instances of PingMon and start pinging immediately. Since Windows shortcuts are limited, there also is a way to run a batch file like this: start PingMon.exe HOST 1 start PingMon.exe HOST 2 ... start PingMon.exe HOST 33 The numbers are used for positioning. Version 0.3 and later contain another tool, PingHist, to visualize log files again: PingHist.exe LOGFILE Will visualize file LOGFILE. *) Versions 0.2 and higher don't run on non-NT systems. This is due to elevation detections. So, on Windows 98 you will have to run 0.1 versions No further dev.

    TraceMAC - Traceroute for MAC addresses

    TraceMAC - Traceroute for MAC addresses

    TraceMAC is a command-line Layer 2 traceroute for Cisco switches

    TraceMAC is a Windows/Linux command-line tool that allows you to trace a specific MAC address thru Cisco switches. It works by connecting to a switch using SSH, SNMP, Telnet, HTTP or HTTPS and do some "show commands" and later process the output, this will happen recursively until it finds the switch where that MAC address (PC/Printer/Etc) is directly connected. Note: It works with Cisco switches only and you must have CDP enabled at least on trunks/links between switches! Is tested with Cisco switches: Catalyst: 2960,3560,3750,4948,6509,9200,9300,9500 (All protocols) Nexus: C9332C, 93180YC-EX (NX-OS SSH) Express 500 (HTTP) FYI: It uses Nbtscan.exe (NetBIOS) as a alternative method to discover the mac address of a host and now seems that it is considered a malware. Anyway it is just a simple network tool that can scan the network similar to NMAP or Angry IP Scanner, etc...
