nping 命令

常用示例

说明

nping is a flexible packet generation and response analysis tool. It extends ping functionality to arbitrary protocol combinations. TCP mode probes ports without completing connections. SYN packets test firewall rules and service availability. Custom flag combinations test TCP stack behavior. UDP probing tests UDP services. ICMP includes various message types beyond echo requests. ARP queries resolve MAC addresses on local networks. Echo mode bounces packets through a server, useful for testing firewalls and NAT traversal. The client sends packets to the server, which returns them. Traceroute mode discovers network paths by incrementing TTL values. It works with TCP, UDP, or ICMP probes. Packet customization includes payload data, timing, and protocol options. This enables protocol research and network testing.
