HWaddr:就是网络卡的硬件地址,俗称的 MAC 是也; inet addr:IPv4 的 IP 地址,后续的 Bcast, Mask 分别代表的是 Broadcast 与 netmask inet6 addr:是 IPv6 的版本的 IP ,我们没有使用,所以略过; MTU:最大传输单元 RX:那一行代表的是网络由启动到目前为止的封包接收情况, packets 代表封包数、errors 代表封...

这是因为分区的唯一标识符发生了改变,grub无法找到正确的分区入口,导致系统无法启动,所以需要修改fstab文件和grub.cfg文件中的UUID号。 一、如何知道现有的分区UUID:可以通过 livecd优盘启动的方式先启动计算机,然后通过 blkid 、ls -l /dev/disk/by-uuid 等命令查看uuid,现记录七种查看uuid的方法。 作为一个 Linu...

mask:与网络目标地址相关联的网掩码(又称之为子网掩码)。子网掩码对于 IP 网络地址可以是一适当的子网掩码,对于主机路由是 255.255.255.255 ,对于默认路由是 0.0.0.0。如果忽略,则使用子网掩码 255.255.255.255。定义路由时由于目标地址和子网掩码之间的关系,目标地址不能比它对应的子网掩码更为详细。换句话说,如...
