后续

• 首次登录 http://192.168.1.1:180/cgi-bin/luci 后，设置 root 密码。

• 更换 zjuvpn 密码, '/etc/config/network', config interface 'zjuvpn'

• FIX: 连接 zjuvpn 后, LAN 无法访问外网, 原因是 adbyby 添加的防火墙

  /etc/config/firewall

  #config include 'adbyby'
  #       option type 'script'
  #       option path '/usr/share/adbyby/firewall.include'
  #       option reload '1' 
  

• FIX: LAN 无法获取校园 ipv6 地址

  /etc/config/dhcp

  config dhcp 'lan'  
        ......
        option dhcpv6 'hybrid'
        option ra 'hybrid'
  

• 5G启用，必须 断电重启 一次。

• 禁用暂时不用的启动项 shadowsocks, ddns, transmission

• 添加 user shmilee

• 添加电脑的SSH公共密钥到 /etc/dropbear/authorized_keys.
  shmilee 登录需要 /etc/shmilee/.ssh/authorized_keys

• wan ssh登录, 需确保防火墙入站数据为接受 option input 'ACCEPT'

• 为 autossh -D 3696 生成一对密钥, 放在 /etc/shmilee/.ssh/.
  公钥添加到3690对应的主机. 手动登录一次, 以生成 /root/.ssh/known_hosts.

• 恢复 nginx 配置, nginx-frontend.conf, ssl-certs/.

• USB外接硬盘, 格式化为 ext4, 卷标 RouterUSB.
