在QNX操作系统中nicinfo是一个用于显示网络接口卡NIC信息的命令行工具。它可以提供有关系统中所有可用网络接口卡的详细信息例如接口名称、MAC地址、IP地址、掩码、广播地址、传输单元大小等等。
通过nicinfo命令可以查看所有网络接口卡的信息也可以通过添加接口名称参数来查看特定接口的信息。
nicinfo命令对于调试和排除与网络有关的问题非常有用也可以用于监视和管理系统中的网络接口卡

ifmcstat是一个命令行程序用于监控和显示网络接口的统计信息。使用ifmcstat可以查看网络接口的包传输数量、丢包数量、传输速率等详细信息。下面是使用ifmcstat的示例命令
./ifmcstat eht0
lo0:inet6 ::1inet6 fe80::1%lo0group ff01:1::1 refcnt 2group ff02::1%lo0 refcnt 2group ff02::1:ff00:1%lo0 refcnt 2

if_up
if_up也是一个命令行程序用于启用和配置网络接口。使用if_up可以设置网络接口的IP地址、子网掩码、网关等参数。以下是使用if_up的示例命令
if_up eth0 192.168.1.10 netmask 255.255.255.0 gw 192.168.1.1
tcpdump
拷贝librpc.so.2和tcpdump至qnx设备中
./tcpdump -i eth0 port 8010 -w out1.cap
