1.配置命令代理

sudo apt-get install polipo

logSyslog = true
logFile = /var/log/polipo/polipo.log
proxyAddress = "0.0.0.0"
socksParentProxy = "127.0.0.1:1080"
socksProxyType = socks5
chunkHighMark = 50331648
objectHighMark = 16384
serverMaxSlots = 64
serverSlots = 16
serverSlots1 = 32

重啟polipo服務

sudo /etc/init.d/polipo restart
 

export http_proxy="http://127.0.0.1:8123/"

curl ip.gs
curl www.google.com

命令視窗重新開啟後，以下命令需要重新執行：

export http_proxy="http://127.0.0.1:8123/"

2.禁用ipv6

vim /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

sudo sysctl -p

將會顯示：

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
 

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

顯示：

1

則成功禁用ipv6
