问题解决记录 ssh connect refused clang(ohos错误) java 网口烧录配置

安装ubuntu并配置有关设备编译环境

  1. 按照正常流程配置ubuntu环境 参考Wait_Aurora同学安装Ubuntu到移动介质并设置好UEFI引导的文章
  2. 在进行远程ssh挂载时,三次出现ssh connect refused情况 在其他电脑中也可以复现,猜测原因是ubuntu本身自带的ssh服务与vmware外的ssh服务需要进行参数和规则修正,需要检查的项目包括
    • 目标主机的ssh server端程序是否安装、服务是否启动,是否在侦听22端口
    • 本机是否设置了iptables规则,禁止了ssh的连入/连出;
	sudo iptables -L
*SSH分客户端openssh-client和openssh-server

如果你只是想登陆别的机器的SSH只需要安装openssh-client(ubuntu有默认安装,如果没有则sudo apt-get install openssh-client),如果要使本机开放SSH服务就需要安装openssh-server:

sudo apt-get install openssh-server

然后确认sshserver是否启动了:

ps -e |grep ssh
# 重启服务
sudo /etc/init.d/ssh stop
sudo /etc/init.d/ssh start

编译时错误

报错信息如下

  1. 在报错中可以看到clang配置有问题,似乎缺少依赖,于是查询“clang-error-while-loading-shared-libraries-libtinfo-so-5“
    找到安装该库的方案
 sudo apt install libncurses5
  1. 在报错中可以看到java 环境配置又问题,参考网上众多ubuntu安装java 的教程进行配置。
  2. 在漫长的等待后编译完成

烧录问题

烧录步骤1 按照指导手册中进行串口烧录,速度极低,在同情况下更换为usb烧录,驱动不能识别,最终购买交换机+usb转wan口进行网口下载

网口下载的操作具体细节

  1. 网口设置

  2. 控制面板中进入以太网设置,设置特定地址和IP,以及DNS

  3. 参考设置如下
IP地址为:192.168.1.5
子网:255.255.255.0
默认网关:192.168.1.1

按照生成的分区表进行下载

烧录问题的一些测试解决方案和备注

在接新硬件时应当注意在虚拟机环境中选择挂载到主机
重新刷新uboot需要找对位置不要写错镜像导致问题。
