5.1 ssh配置
1、 确认ssh服务已安装，通过普通用户连接成功， service ssh status systemctl status ssh
下面是scp拷贝命令。 #scp XILINX_AI_SDK-ZCU102.tar.gz root@IP_OF_CARD:~/
2、ssh远端显示配置 #cat /etc/ssh/sshd_config X11Forwarding yes X11UseLocalhost no – 禁止将X11转发请求绑定到本地回环地址上 AddressFamily inet – 强制使用IPv4通道
3、确认ssh配置对root进行特殊设置，修改/etc/ssh/sshd_config文件中 PermitRootLogin without-password将 without-password改为yes。
4、重启ssh服务/etc/init.d/ssh restart。 #systemctl restart sshd.service #systemctl restart sshd
5.2 ping地址测试 5.3增加域名服务器 编辑域名服务器 vi /etc/resolvconf/run/resolv.conf dns-nameservers 8.8.8.8
亦可在/etc/network/interfaces文件中设置。
5.4 ping域名测试
硬件使用以下USB以太网卡进行连接
6.1 Interfaces配置 route print netstat -nr tracert
netsh interface ip set address “以太网” static 192.168.1.7 255.255.255.0 192.168.1.1 1 auto: the interface should be configured during boot time. iface : interface inet: interface uses TCP/IP networking. That means interface eth0 should be configured during boot time , and interface name eth0 uses TCP/IP protocol and can be configured by Dhcp . Gateway 192.168.1.1 Route -n root@pynq:/etc/network# vi interfaces #interfaces(5) file used by ifup(8) and ifdown(8) #Include files from /etc/network/interfaces.d: #source-directory /etc/network/interfaces.d auto eth0 iface eth0 inet static address 192.168.1.15 gateway 192.168.1.1 netmask 255.255.255.0 dns-nameservers 8.8.8.8 #network 192.168.1.0 #broadcast 192.168.1.255
sudo /etc/init.d/networking restart route del default route add default gw 192.168.1.1
6.2 使用MobaXterm工具 6.3 使用命令行 Using the Ethernet Interface SSH service is enabled by default. You can log into the system using an SSH client after the board has booted.
Figure 15: Logging into the Evaluation Board Using SSH
Use the ifconfig command via the UART interface to set the IP address of the board, then use the SSH client to log into the system. 通过以下命令配置网络：
ifconfig eth0 192.168.1.10 netmask 255.255.255.0
Note：The DNNDK examples won’t work through a UART connection due to the lack of Linux windows.
以下介绍四种方法，总有一款适合你。 7.1 初始配置wifi 7.1.1 Interfaces地址文件 打开MobaXterm的串口进行配置
其原因是原有的启动文件默认不启动无线网卡，可使用vi编辑启动文件，命令是： root@xilinx-ultra96-v2019:/etc/network# vi interfaces 在wireless interfaces区域增加命令auto wlan0即可，接入的无线网络配置可在wap_supplicant.conf文件中完成，实现多网络自动切换; 另一种方法是通过wicd-curses中的高级设置也可完成，只不过后一种方法每次启动都要重设。
vi /etc/network# vi interfaces
下图为动态配置 下图为静态配置 #interfaces(5) file used by ifup(8) and ifdown(8) #Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d
allow-hotplug eth0 iface eth0 inet static address 192.168.1.15 gateway 192.168.1.1 netmask 255.255.255.0
dns-nameservers 8.8.8.8
vi /etc/network/interfaces.d
auto wlan0 iface wlan0 inet static address 192.168.1.16 gateway 192.168.1.1 netmask 255.255.255.0 wpa-conf /etc/wpa_supplicant.conf
或者 iface wlan0 inet dhcp #ifconfig wlan0 192.168.1.16 #gateway 192.168.1.1 wireless_mode managed wireless_essid any wpa-driver wext wpa-conf /etc/wpa_supplicant.conf 7.1.2 配置wap_supplicant.conf文件 #vi wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 update_config=1
network={ key_mgmt=WPA-PSK ssid=“JOHNAP” psk=“91823615” priority=1 }
network={ key_mgmt=WPA-PSK ssid="star " psk=“418418418” priority=3 }
network={ key_mgmt=WPA-PSK ssid=“CMCC-407” psk=“91823615” priority=5 }
或使用命令行写入 wpa_passphrase TPLINK 12345678 |sudo tee -a /etc/wpa_supplicant/wpa_supplicant.conf
#priority:连接优先级,数字越大优先级越高 7.2 设置启动脚本 在某些情况下，采用7.1中介绍的方法可能无效，原因未究，可采用下面的办法。 在/etc/init.d/ 下新建脚本wifi.sh root@pynq:~# sudo vi /etc/init.d/wifi.sh
#!/bin/bash ###BEGIN INIT INFO #Provides: wifi #Required-Start: $all #Required-Stop: #Default-Start: 2 3 4 5 #Default-Stop: ###END INIT INFO ifconfig wlan0 up ifconfig wlan0 192.168.1.16 wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf –B
上面的程序前段必须设置启动优先级。
改变执行权限与重启网络： chmod +x /etc/init.d/wifi.sh sudo systemctl enable wifi.sh
如果未设置启动优先级，则出现： 7.3 单次启动wicd-cureses 配置wicd-cureses文件 running ‘wicd-curses’ from the terminal or over the UART
点击－〉，进入配置页面，用箭头一直往下走，走到走不动为止，配置密码帐号。
网络重启 sudo /etc/init.d/networking restart 7.4 命令行启动 netsh interface ip set address “WLAN” static 192.168.1.10 255.255.255.0 192.168.0.1 1 netsh interface ip set address “WLAN” dhcp 查看网络并输入帐号密码 iwlist scanning | grep ESSID #iwlist wlan0 scanning iwconfig wlan0 essid “CMCC-407” key 9182-3615 #iwconfig wlan0 key s:12345 iwconfig wlan0 ap auto" ip route show 192.168.3.0/24 dev wlan0 proto kernel scope link src 192.168.3.3

用ipconfig察看WLAN IP 地址是否是192.168.1.10
7.5.2开发板侧设置 计算机上打开MobaXterm软件 双击SSH，输入下图中的三个框中的数值 IP地址和username 双击左侧刚建立的192.168.1.16(root)
展示进入Ultra96开发板上的文件界面
由于计算机的IP地址可能设置与网关的网段不一致，可能导致计算机无法上网，恢复计算机IP地址自由分配命令如下： netsh interface ip set address “WLAN” dhcp 当然亦可以将开发板与计算机的IP地址与无线局域网设成一个网段，既可以连通，也可以上网。 UP Board 网络设置一本通 - 思兼 - 开发者的网上家园 https://www.cnblogs.com/sjqlwy/p/up_nwm.html 7.6 热点连接 请注意，本节内容作者并未试过，仅转载。
具体方法如下：使用ap-hotspot来创建WIFI热点，而不要用Ad hoc。终端输入： $ sudo add-apt-repository ppa:nilarimogard/webupd8 $ sudo apt-get update $ sudo apt-get install ap-hotspot $ sudo ap-hotspot configure //这一步会检查ubuntu的网络和WIFI接口，确定后会提示你配置热点，输入ssid和密码之类的就行了 $ sudo ap-hotspot start

Connect with SSH and use X11-Forwarding to PC 在使用MobaXterm工具软件时，只要点击ssh连接时输入正确的开发板IP地址，会自动设置好。 Make sure to enable X11 forwarding with the following command (supposed that host machine IP address is 192.168.0.16) when logging in to the board since all the examples require a Linux windows system to work properly. On Windows, connect to the target over the network using an SSH client that provides an X-server, such as MobaXterm. Ensure that X11-forwarding is enabled, and the DISPLAY environment variable is setup correctly. When an application is launched from this shell, the output will be forwarded back to the PC and displayed in a separate window.
默认运行Ｘ11时，通过本人亲测，远端开发板DISPLAY以下设置，可以在本地计算机上显示图形， DISPLAY=localhost:10.0 DISPLAY=主机IP地址:0.0 以下是不能在本地计算机上显示的： DISPLAY=localhost:0.0 DISPLAY=主机IP地址:10.0 DISPLAY=开发板IP地址:0.0 DISPLAY=开发板IP地址:10.0 设置方法举例： export DISPLAY=192.168.1.4:0.0 查看命令：env
以下命令应该有用，未证实 For Linux (or windows command line) you can use the following command: ssh -X root@[IP address of Ultra96]. ssh –X root@192.168.1.2 ssh -X xxx.xxx.xxx.xxx
使用命令行配置SSH terminal ssh -X root@[IP address of Ultra96]. ssh –X root@192.168.1.15 export DISPLAY=192.168.0.15:0.0 Host *
那么登录之后DISPLAY变量自动设置为本地的X Window. 在这个登录中打开的所有X程序,其图形会自动转发到本地. 这样可以省却指定display参数,而且不用担心xhost的权限问题. 在这里只是简单介绍一下ssh的X转发。
