Answers:
如果有ifupdown
(很可能在使用Debian或基于Debian的发行版),请查看man interfaces
:
post-up command
Run command after bringing the interface up. If this command fails then ifup aborts, refraining from marking the interface as con‐
figured (even though it has really been configured), prints an error message, and exits with status 0. This behavior may change in
the future.
所以/etc/network/interfaces
你可以有类似
auto eth0
iface eth0 inet dhcp
post-up /usr/local/sbin/my-custom-script
将eth0替换为您的实际接口。
