This Eclipse RCP application contains several free, useful networktools. Among others:
- Standard networktools: ping, netstat, traceroute, nslookup
- A port scanner
- Servers: HTTP, FTP, TFTP servers
- an HTTP proxy
- A TCP tunnel
- Clients: FTP client, embeddable PuTTY (for Windows only)
NetworkTools has 2 components: A protocol analyzer which plays a TCP client or server or pipeline, which sits between a client and server and shows how they communicate. A port scanner can scan a range of IP addresses and ports. See screenshots.
