Docker Hub 镜像加速器

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

Dockerized 实践 https://github.com/y0ngb1n/dockerized

Install tcpkill
yum -y install dsniff --enablerepo=epel

View connections
netstat -tnpa | grep ESTABLISHED.*sshd.

Block with ip tables
iptables -A INPUT -s IP-ADDRESS -j DROP

Kill connection
