这种工具不开源的都不敢用

VBOX 的话，选 Host-Only 模式，主机会多一块网卡，用 192.168.56.1 这个 IP，而且开启 DHCP。虚拟机是 192.168.56 段的网址，可以和主机访问，如果有多个同模式的虚拟机，他们直接也可以互相访问。HOST 可以 SSH 进去。

得了吧， 小米的 6G 运存只能当 3G 用

@Acoffice #42 大水果已经做了

可以要求小米披露到底收集了哪些关于你的信息

CentOS，PPPoE，IP Forwarding，IP Masquerade，firewalld，bind9，dhcpd，Apache, MariaDB, PHP, Python，ownCloud，...

这种配置根本不考虑 MS 的系统

不都是 PDO 么

想到这这个梗：it's not a bug, it's a feature!

@cent777 #10 所以这是段子？

宠物而已，正常

呵呵，墙国

宁愿用台旧的或二手笔记本，跑正宗的 CentOS，配各种服务来玩

吓得赶紧连了一下自己的吃灰搬瓦工

```
zone "baidu.com" {
type master;
file "/etc/named/zones/dummy-block";
allow-update { "none"; };
};
```

samba 共享 + 磁盘配额有什么好办法？哪位大大指点下？

@tees #28

之前测试过的配置，参考下。

# Anonymous and Selected Users

* Anonymous (nobody / guest) has the READONLY permission
* Authorized users (in sambausers group) have the READ/WRITE permission

## Add necessary group

```
# groupadd sambausers
```

Check

```
# cat /etc/group
```

## Add necessary users

Remove them first

```
# userdel -f sambauser1
# userdel -f sambauser2
```

Add

```
# useradd -m sambauser1 -G sambausers
# useradd -m sambauser2 -G sambausers

# echo 1234 | passwd --stdin sambauser1
# echo 1234 | passwd --stdin sambauser2
```

Check

```
# cat /etc/passwd
```

## Create directory in system

```
# mkdir -p /srv/ssharea
```

## Change directory's group

```
# chgrp sambausers /srv/ssharea
```

## Change directory's mode

(Users who in sambausers group can create file/directory in project)
(and these files/directories' owner are themself, group are sambausers)
(Give anonymous (nobody / guest) the ability to view its contents)

```
# chmod 2775 /srv/ssharea
```

## Add Samba users (and password)

```
# pdbedit -a -u sambauser1
```

(type password twice to create)

```
# pdbedit -a -u sambauser2
```

(type password twice to create)

## Edit /etc/samba/smb.conf

```
# vi /etc/samba/smb.conf

[global]
workgroup = WORKGROUP
netbios name = LINUXSERVER
server string = This is a Linux Samba Server

passdb backend = tdbsam

unix charset = utf8
; display charset = utf8
dos charset = cp932

log file = /var/log/samba/log.%m
max log size = 50

security = user
guest account = nobody
map to guest = bad user

ntlm auth = yes

load printers = No


[ssharea]
comment = SSHAREA
path = /srv/ssharea
browseable = Yes
writable = No
write list = @sambausers
guest ok = Yes
```

## Start

```
systemctl start smb
systemctl start nmb
```

试试配个 Postfix

@xiaochocking #13

```
getPwrValue4( ){
// 加权平均返回 getPwrValue, getPwrValue2 and getPwrValue3 的结果
}
```
