Problem & Summary

after booted, type F2, change network configuration to 10.13.72.5/24 with gateway=10.13.72.1, which is the ip of lede, one of the vm that’s going to be created

lede frequently crashed its network, need to set up a cron job to check and re-up network every 2 mins

#!/bin/sh
# filename: /root/network-watch-dog.sh
# 4=network error/refused/timeout/dns err/
# need "opkg install wget ca-bundle"

count=0
URLs='http://baidu.com  http://163.com  http://www.qq.com'
for host in $URLs ; do
    #echo $host
    # wget -t2 这个参数要>=2, 防止第一次访问dns解析超时,而导致失败
    wget -q -T2 -t2 --method=HEAD --max-redirect=0 "$host"
    if [ 4 -eq $? ]; then
        echo $(date +%F_%T%z) $host 'error.' >> /root/log.redail
        count=$((count+1))
    else
        break
    fi
done
URL_cnt=$(echo $URLs|wc -w)
if [ $count -ge $URL_cnt ]; then
    echo $(date +%F_%T%z) redail >> /root/log.redail
    ifdown WAN;sleep 1;ifup WAN
fi

echo $(date +%F_%T%z) 'finished run' >> /root/log.redail

Lede openwrt setting

lede (WAN - static, get 10.13.0.72; LAN - static, 10.13.72.1/24)

making sure the one with X, the management port, is the port that you will connect directly with computer for root access

with direct wired connection to the right management port (check back of machine for info), need to set computer with static ip, that is 10.13.72.x/24
