为什么 ifup 没有运行所有 if-pre-up.d 脚本？

Question

$ ll /etc/network/if-pre-up.d/

total 20
drwxr-xr-x 2 root root 4096 Jan 15 16:43 ./
drwxr-xr-x 7 root root 4096 Jan 14 21:29 ../
-rwxr-xr-x 1 root root  344 Apr 28  2012 ethtool*

lrwxrwxrwx 1 root root   32 Dec  4 13:00 wpasupplicant -> ../../wpa_supplicant/ifupdown.sh*

$ sudo ifup --all -v

为什么 iptablesload.sh 没有运行？是否有其他位置设置了预备脚本列表？

Answer 1

我也遇到了同样的问题。据我所知，如果您删除结尾的“.sh”，则应该可以正常工作。

sudo mv /etc/network/if-pre-up.d/iptablesload{.sh,}

Answer 2

我在 ubuntu 20.4 中也无法工作。脚本名为 iptablesload，位于 if-pre-up.d 目录中。

我必须做

安装 ifupdown

这应该可以解决 U 20.4 的问题，对我来说确实如此。
