Network|Network NameSpace

CSDN上NameSpace好多文章都是翻译的这个
在后面还提供了一个非常骚气的操作:

$ ip netns exec ns1 /bin/bash --rcfile <(echo "PS1=\"namespace ns1> \"")

【Network|Network NameSpace】另外还介绍了Linux怎么配置转发,但是太长了呀,记不住,而且要NAT...
# Share internet access between host and NS.# Enable IP-forwarding. echo 1 > /proc/sys/net/ipv4/ip_forward# Flush forward rules, policy DROP by default. iptables -P FORWARD DROP iptables -F FORWARD# Flush nat rules. iptables -t nat -F# Enable masquerading of 10.200.1.0. iptables -t nat -A POSTROUTING -s 10.200.1.0/255.255.255.0 -o eth0 -j MASQUERADE# Allow forwarding between eth0 and v-eth1. iptables -A FORWARD -i eth0 -o v-eth1 -j ACCEPT iptables -A FORWARD -o eth0 -i v-eth1 -j ACCEPT
