LINUX:ARCHLINUX Virtualbox 如何用 host interface

从VirtualBox 2.1.0 开始支持直接从客户机来实现Host interface功能。只需要在rc.conf中 的MODULES中加入 vboxnetflt 之后在你虚拟机设置中选择Host Interface Networking。

测试方法：

modprobe vboxnetflt

设置->网络-》连接方式 ： Host Interface

启动虚拟机


如果OK，在/etc/rc.conf 中加入 vboxnetflt 模块，重启计算机即可。

LINUX:ARCHLINUX How to access mysql remotely

如何开启mysql 的侦听允许远程访问？



1.请在/etc/hosts.allow 添加以下行:

mysqld : ALL : ALLOW mysqld-max : ALL : ALLOW   2.需要编辑/etc/my.cnf把skip-networking注释掉：  #skip-networking     You can get the "error no. 2013: Lost Connection to mysql server during query" message instantly whenever you try to connect to the MySQL daemon by TCP/IP. This is the TCP wrappers system (tcpd), which uses the hosts_access(5) system to allow or disallow connections.   # Don't listen on a TCP/IP port at all. This can be a security enhancement, # if all processes that need to connect to mysqld run on the same host.     # All interaction with mysqld must be made via Unix sockets or named pipes. # Note that using this option without enabling named pipes on Windows       # (via the "enable-named-pipe" option) will render mysqld useless!

电信商务领航定制终端 大亚 DB120-B1 配置方法

公司装宽带，电信送了个无线路由加猫的东东，叫电信商务领航定制终端，型号是大亚 DB120-B1 。
公司的技术员说无法自动拨号上网，所以没用。那好，我就看看，电信这会是黄鼠狼还是喜羊羊。

回家，接上自己家的ADSL，开始操作。

按说明书，一步一步的做

1.设置自己PC的IP为  192.168.1.2

2.用配的交叉线连路由的LAN1

3.输入   http://192.168.1.1  
(如果不行，试试https://192.168.1.1)
username :   telecomadmin
password:     nE7jA%5m

4.网络-宽带设置

连接名称： 新建一个连接
连接模式：Route
             选       pppoE
NAT : YES
VPI:8
VCI:35
服务类别：UBR WITHOUT PCR
启用VLAN： NO
VLAN ID：
封装：LLC/SNAP-BRIDGING
用户名：电信账户
密码：电信密码
服务名称：CHINATELLECOM
启用802.1优先级：YES
端口绑定：仅INTERNET
                端口全选


然后设置WLAN和DHCP，这些不详说，

设置后，一定要到  管理-设备管理-保存/重启  ，设置才会生效。


重启后，看看 状态-网络侧信息

如果出现 

8/35

Off

PPPoE

Up

219.137.210.254

这行，恭喜，成功了！

没有出现？也不用灰心，因为你和笔者不在同一个城市，GOOGLE一下你城市的VPI和VCI吧。我的技术员也就是填错了这里。
