去年年初，为了体验4k的“塞尔达传说-旷野之息”，我升级了我的电脑，并在18年不断完善，目前经过optane加速的4T硬盘，速度提升非常显著，很是喜欢。但电脑里有些录音，以及家庭照片，想随时观看，而不想开电脑，另外也起到备份的作用（数据无价），所以一直在考虑采购一台NAS，但感觉现在的NAS及配件（硬盘）功能比较弱（其实就是没米。。。），所以就考虑利用现有资源，把1T的闲置移动硬盘挂载到 WRT1200路由器下，这样 Win/Mac/手机 通过sshfs/samba远程挂载目录，这样可以体验简易NAS，等时机成熟了再考虑NAS，此篇主要总结如何挂载移动硬盘，由于环境版本的不同，总结中的内容可能跟读者遇到的会有少许差异，如遇到问题，可自行google或baidu

有时候通过LEDE的luci直接挂载不起作用，也弄不明白为啥，所以还是CLI最靠谱。另外在openwrt里，移动硬盘的格式最好是ext3或ext4，这样效果高，问题少。另外就是最开始我想用sshfs，但后来发现windows访问sshfs效果非常不好，所以对于windows，就换回了samba服务器，速度不错，可以达到平均60MB/s 上下

另外Samba配置，可以参考我之前的文章 Deploy Samba on OpenWRT

1. 国内更新源，这样就可以随便更新软件了

Cisco finally published the YangSuit at Devnet at Feb 2021, that can be downloaded and used by customer, and it is Free! I updated the installation section of the article to use the public version, other section should similar and not update.

Cisco YANG Suite provides a set of tools and plugins to learn, test, and adopt YANG programmable interfaces such as NETCONF, RESTCONF, gNMI and more.

YANG Suite will provides network operators with a common tool to interact with Cisco IOS XE, IOS XR, and the NX-OS Network Operating Systems as they look to modernize their network management and migrate from traditional network management tools.

Introduction

I installed the WAE 6.4.5 at formal and summaried to Blog, e.g: INSTALL CISCO WAE 6.4.5. After 7.0, install/config have big change and similar with NSO that easy/module to deploy. For this article, only talk about how to install and enable.

Auto source profile

Similar with NSO, add “source” command to “.bash_profile” that in MacOS. That will let you direct to login to WAE but not do “source wae711/waerc”, as follow:

[root@frank ~]# echo "source /opt/wae711/waerc" >> .bash_profile
[root@frank ~]# more .bash_profile | grep wae
source /opt/wae711/waerc

部署虚拟开发环境

虽然自己不是软件工程师，但有时候为了测试会写一些小程序，所以常常需要在自己电脑上设置开发环境。由于MacOS原生支持Python，所以我们可以不用那么麻烦的设置开发环境。但为了系统的稳定性，还是不要随便增加或变更自带的python，所以开发环境直接用虚拟环境就可以了，大概构架如下：
