【解决办法】：start/stop udhcpc的方法，经验证很不稳定，有时重新获取ip需要20多秒；后来用了release/renew方法后，软件表现稳定，并且速度很快。【具体做法】：释放ip：执行语句 kill(udhcpc_pid, SIGUSR2); （udhcpc_pid为开启的udhcpc的进程pid）重新获取ip：执行语句 kill(udhcpc_pid, SIGUSR1);...
使用udhcpc配置静态IP地址、子网掩码、网关和DNS服务器是不太合适的,因为udhcpc是用于获取动态主机配置协议(DHCP)信息的工具。如果你需要进行静态配置,可以参考以下方法: 配置IP地址和子网掩码: ifconfig eth0<ip_address>netmask<subnet_mask> 配置默认网关: route adddefaultgw<gateway_ip> 配置DNS服务器: 在/etc...
sudo systemctl disable dhcpcd sudo systemctl stop dhcpcd 4. 预防措施 定期检查和更新网络配置:确保 DHCP 服务器和客户端的配置文件是最新的,并且与网络环境相匹配。 监控网络状态:使用网络监控工具定期检查网络状态和流量,及时发现并解决问题。 备份和恢复:定期备份网络配置文件和系统状态,以便在出现问题时能够快速...
