写个shell脚本：Linux下定时重启ipv6

运行环境：Ubuntu-server-22.04 lts.

#!/bin/bash

# Disable IPv6
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

# Wait for a few seconds
sleep 5

# Enable IPv6
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=0
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=0

# Show the IPv6 status
cat /proc/sys/net/ipv6/conf/all/disable_ipv6

设置定时运行脚本：

# Edit the cron table
crontab -e

# Add the following line to run the script every day at 1 AM
0 1 * * * /path/to/reset-ipv6-script.sh

根据你的实际需要定时重启ipv6即可。
