运行 Linux 版本 2.6.26.5、ARM Linux 内核的嵌入式设备。Busybox v1.10.2 shell (ash),我在 Busybox shell 中。我想建立嵌入式设备和计算机之间的连接。是否可以从 Busybox shell 手动设置网络连接?我安装了主虚拟文件系统 (proc、sysfs、tmpfs、/dev/pts),然后输入命令来设置网络,但没有成功。我猜,可能是某些模块或驱动程序未在此 shell 模式下加载,但我不确定。

答案1
Busybox 软件包中包含 ip 命令。这样您就可以向这样的接口添加 ip 地址。(将 <examples> 替换为您的值)
ip addr add <10.128.55.2> dev <eth0>
它还包括路线和链接配置选项。以下是文档:https://linux.die.net/man/8/ip
