My VPS(Bandwagon) include OpenVPN script, but only support Centos6.x that version not good for docker (my blog deploy by docker Blog顺利完成搬家之Bandwagonhost VPS), so need to do by other scripts. OpenWRT config OpenVPN client has some different, so summary the info to the article for review.

But due to GFW, OpenVPN couldn’t establish at last, reset happened between server and client, but the setup should workable.

Deploy OpenVPN at Server

Don’t know why couldn’t find OpenVPN pacakage by yum, even if have epel source

[root@frank ~]# rpm -qa |grep epel
epel-release-7-11.noarch
[root@frank ~]# yum install openvpn
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

No package openvpn available.

Config call-home that active smart license

xrv9k should have some default call-home, in some scenario, need to add some extra configuration, as follow:

domain name cisco.com
domain name-server x.x.x.x  >>> dns server
call-home
 service active
 contact smart-licensing
 http-proxy y.y.y.y port 80  >>> proxy server
 profile CiscoTAC-1
  active
  destination transport-method http

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.
