2.13: With the same start parameters, the Linux version can start normally, but the Windows version cannot

[GarinQian]

Describe the bug
With the same start parameters, the Linux version can start normally, but the Windows version cannot.

System Setup
on windows:
.\weed.exe server --master.port=9333 --volume.port=9222 --volume.max=200 --filer --filer.port=9111 --dir="D:\weed\seaweedfs"
on CentOS7.4:
./weed server -master.port=9333 -volume.port=9222 -volume.max=200 -filer -filer.port=9111 -dir="./data"

• OS version
  version 30GB 2.13 0e99531 windows amd64
  version 30GB 2.13 0e99531 linux amd64

• if using filer, show the content of filer.toml
  [mysql] # or tidb
  enabled = true
  hostname = "localhost"
  port = 3306
  username = "user1"
  password = "password1"
  database = "database1" # create or use an existing database
  connection_max_idle = 2
  connection_max_open = 100
  Expected behavior
  successfully visit http://127.0.0.1:9111

on windows:
.\weed.exe server --master.port=9333 --volume.port=9222 --volume.max=200 --filer --filer.port=9111 --dir="D:\weed\seaweedfs"

can you use single dash instead of double dash?

不好意思之前表述的不太清楚，问题不是一个-和两个--，问题是windows启动的时候没指定ip和ip.bind，出现了如上面第一个截图中的获取到本地IP（10.122.0.154:9333）作为master，但是当时ipconfig出来并没有这个ip。今天又试了一下同样的步骤又没有复现了。

Thanks for the update!

[GarinQian]

昨天在家里没有复现，今天来公司办公室测试了一下，遇到了同样的问题。应该是跟公司的网络环境有关，我重新表述一下问题：

版本：version 30GB 2.13 0e99531 windows amd64

启动方式（并不是-和--的问题，windows上参数必须是--才能识别）：
方式一：.\weed.exe server --master.port=9333 --volume.port=9222 --volume.max=200 --filer --filer.port=9111 --dir="D:\weed\seaweedfs"
方式二：.\weed.exe server --ip=localhost --ip.bind=localhost --master.port=9333 --volume.port=9222 --volume.max=200 --filer --filer.port=9111 --dir="D:\weed\seaweedfs"

现象：方式二正常启动；方式一启动失败。
方式一失败原因：获取到本地IP（10.122.0.154:9333）作为master，但是10.122.0.154并不在本地网卡的IP列表里，也不在路由表的IP列表中。

测试：尝试把/weed/util/network/DetectedHostAddress修改为如下，则可以正常获取到本地IP：
`func DetectedHostAddress() string {
netInterfaces, err := net.Interfaces()
if err != nil {
glog.V(0).Infof("failed to detect ip address: %v", err)
return ""
}

for i := 0; i < len(netInterfaces); i++ {
	if (netInterfaces[i].Flags & net.FlagUp) != 0 {
		addrs, _ := netInterfaces[i].Addrs()

		for _, address := range addrs {
			if ipnet, ok := address.(*net.IPNet); ok && !ipnet.IP.IsLoopback() {
				if ipnet.IP.To4() != nil {
					return ipnet.IP.String()
				}
			}
		}
	}
}

return "localhost"

}`

[chrislusf]

set -ip

the ip info is to identify the server itself.

[GarinQian]

嗯我现在加了-ip。我之前看你这边提供了默认获取本机地址，就没有设置-ip。可以考虑完善一下DetectedHostAddress，正确获取本地的可用IP。

Thanks for the suggestion! Added 0213587

You are welcome to make a PR later!

[GarinQian]

Thanks for the quick response. I will try it later. By the way, do you have any discussion groups? Sometimes, as users, we can find someone to discuss and exchange experience when we encounter problems.

[chrislusf]

you can use slack.

there are also two wechat groups. My wechat account is chrislusf
