综上所述,针对“udhcpc: invalid option -- 'g'”的问题,建议用户检查udhcpc的帮助信息以确认正确的选项,并考虑使用其他方法来满足他们的网络配置需求。
就以上三点,我们可以直接使用刚刚提到的 option 组合来实现:\udhcpc -i <IFACE> -p /var/run/udhcpc-eth0.pid -b -t 3 -A 60 理论上要不到ip,会进入背景,并且 重启 60 sec之后才会再丢3次discover封包,若可以要到的话,就可以直接要到IP,daemon还是会存在,若要不到的话,会重新计数 retry时间,然后60s...

如下: udhcpc -b -i eth0 -p /var/run/udhcpc.pid -R解释一下,-b就是切换到后台指令,-i是指定使用哪个网络接口,双网卡的时候一定要使用它来指定eth0 or eth1。 当没有网络的时候,板子一直发送dhcp请求,导致程序不往下执行,解决的办法是把它切换到后台运行,可是如何切换到后台呢,有办法,它自带参数可以...
