2.11.2.1、ubuntu14.04上网问题

第一：选择NAT方式

第二：配置/etc/network/inerfaces文件中使用dhcp方式

root@xfj-virtual-machine:/etc/network# pwd
/etc/network
root@xfj-virtual-machine:/etc/network# ls
if-down.d  if-post-down.d  if-pre-up.d  if-up.d  interfaces  interfaces.d


//内容
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo                                  //开机自动激lo接口
iface lo inet loopback                   //配置lo接口为环回口  

auto ens32                               //开机自动激活ens32接口  
iface ens32 inet dhcp                    //配置eth0接口为动态设置IP地址  
address 192.168.1.141
netmask 255.255.255.0

第三：

然后重启网卡，确认ip地址得到后即可上网。
ifconfig ens32 down关闭网卡
ifconfig ens32 up开启网卡

//重启网卡
root@xfj-virtual-machine:/etc/network# ifconfig ens32 down
root@xfj-virtual-machine:/etc/network# ifconfig ens32 up;

//确认是否能够上网
root@xfj-virtual-machine:/etc/network# ping ww.baidu.com

64 bytes from 110.242.68.66 (110.242.68.66): icmp_seq=10 ttl=128 time=50.9 ms

//能够上网

第五：查看NAT时候的动态IP地址

root@xfj-virtual-machine:/etc/network# ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.193.128  netmask 255.255.255.0  broadcast 192.168.193.255
        ether 00:0c:29:cf:47:ba  txqueuelen 1000  (以太网)
        RX packets 18139  bytes 17972689 (17.9 MB)
        RX errors 0  dropped 1  overruns 0  frame 0
        TX packets 5399  bytes 436515 (436.5 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (本地环回)
        RX packets 597  bytes 44208 (44.2 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 597  bytes 44208 (44.2 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

第一:选择桥接方式

第二：配置桥接到无线网卡（如果主机windows是通过有线上网的，则桥接到有线网卡）；

第三：配置/etc/network/inerfaces文件中使用dhcp方式；

root@xfj-virtual-machine:/etc/network# pwd
/etc/network
root@xfj-virtual-machine:/etc/network# ls
if-down.d  if-post-down.d  if-pre-up.d  if-up.d  interfaces  interfaces.d


//内容
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo                                  //开机自动激lo接口
iface lo inet loopback                   //配置lo接口为环回口  

auto ens32                               //开机自动激活ens32接口  
iface ens32 inet dhcp                    //配置eth0接口为动态设置IP地址  
address 192.168.1.141
netmask 255.255.255.0

第四：

然后重启网卡，确认ip地址得到后即可上网。
ifconfig ens32 down关闭网卡
ifconfig ens32 up开启网卡

//重启网卡
root@xfj-virtual-machine:/etc/network# ifconfig ens32 down
root@xfj-virtual-machine:/etc/network# ifconfig ens32 up;

//确认是否能够上网
root@xfj-virtual-machine:/etc/network# ping www.baidu.com

//能够上网

第五：查看桥接时候的动态IP地址

root@xfj-virtual-machine:/etc/network# ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.3.196  netmask 255.255.255.0  broadcast 192.168.3.255
        ether 00:0c:29:cf:47:ba  txqueuelen 1000  (以太网)
        RX packets 17987  bytes 17945881 (17.9 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 5320  bytes 426753 (426.7 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (本地环回)
        RX packets 546  bytes 40771 (40.7 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 546  bytes 40771 (40.7 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

前提： 开发板和电脑之间通过网线连接好

第一：选择桥接方式

第二：配置桥接到有线网卡（如果配置为自动或者配置桥接到无线网卡则肯定无法ping通开发板）；

第三：配置/etc/network/inerfaces文件中使用static方式，ip地址配置保证和主机windows、开发板三者处于同一网段；

//设置虚拟机IP地址为192.168.1.141（静态IP地址），网络掩码255.255.255.0

root@xfj-virtual-machine:/etc/network# pwd
/etc/network
root@xfj-virtual-machine:/etc/network# ls
if-down.d  if-post-down.d  if-pre-up.d  if-up.d  interfaces  interfaces.d
root@xfj-virtual-machine:/etc/network# vim interfaces

//内容
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto ens32
iface ens32 inet static
address 192.168.1.141
netmask 255.255.255.0

//重新启动ubuntu
root@xfj-virtual-machine:/etc/network# reboot

//查看静态IP地址
root@xfj-virtual-machine:/etc/network# ifconfig
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.141  netmask 255.255.255.0  broadcast 192.168.1.255  //由此可以看出，已经设置好
        inet6 fe80::20c:29ff:fecf:47ba  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:cf:47:ba  txqueuelen 1000  (以太网)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 61  bytes 7013 (7.0 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (本地环回)
        RX packets 393  bytes 25281 (25.2 KB)

        TX packets 393  bytes 25281 (25.2 KB)

//设置电脑IP地址：192.168.1.10，网络掩码：255.255.255.0

//设置开发板IP地址：192.168.1.20，网络掩码：255.255.255.0

bootdelay=10

此处bug要特别注意，不然有可能不会成功。

2.11.2.2、搭建openssh环境

(1)安装ssh-server。(sudo apt-get install openssh-server)如果报错提示依赖错误。可以参考http://www.cnblogs.com/mliudong/p/4094519.html

xfj@xfj-virtual-machine:~$ sudo apt-get install openssh-server

//.确认sshserver是否安装好,如果看到sshd那说明ssh-server已经启动了
xfj@xfj-virtual-machine:~$ ps -e | grep sshd
  3486 ?        00:00:00 sshd

//安装ssh-client
xfj@xfj-virtual-machine:~$ sudo apt-get install openssh-client

(2)securecrt登录

连接

New Session(SSH2)
