saltstack master无法收到minion

遇到的问题如下：

root@Saltstack:/etc/salt# salt-key -L

解决方法：
1，minion 无法认证 master, 查看minion 和master 配置问题，没有问题.
注：

2，minion , master 之间可以ping 通。本身在一台机器上。
3，从另一个minion进行测试。到60秒没有反馈。
4，根据这个提示
[WARNING ] Unable to bind socket, error: [Errno 99] Cannot assign requested address
The ports are not available to bind
调整端口数量。还是不好使，说明报错有问题，不是端口问题。
# echo 16777216 > /proc/sys/net/core/rmem_max
# echo 16777216 > /proc/sys/net/core/wmem_max
# echo "4096 87380 16777216" > /proc/sys/net/ipv4/tcp_rmem
# echo "4096 87380 16777216" > /proc/sys/net/ipv4/tcp_wmem
5 根据这个提示
[WARNING ] Unable to bind socket, error: [Errno 99] Cannot assign requested address
The ports are not available to bind
删除相关运行内容。

killall -SIGUSR2 salt-master
还是不好使，说明报错有问题，不是进行服务问题。
6 但是多次表明是ip地址的问题。最后进入python使用以下命令
#!/usr/bin/python env
import socket
myname = socket.getfqdn(socket.gethostname())
myaddr = socket.gethostbyname(myname)
print"myname= %s"% myname
print"myaddr= %s"% myaddr
反回值的地址，不是我机器地址。是10.10.10.10
而master 和minion配置的是192.168.10.10

ifconfig 查看机器地址为10.10.10.10 哦~~~~~~~~~~
为什么呢？因为我应用的是cloudstack上的VM，couldstack网络做了nat .

一会儿再写一下couldstack网络的问题分解。
