This post is a long overdue tutorial on how to setup govc. What is govc? It’s a cli utilizing govmomi, a go library used to interact with vSphere API. Why use govc? It’s fast and way better to use for automation tasks. Installation: Download release binary here: https://github.com/vmware/govmomi/releases Depending on the platform, decompress: gzip -d govc_linux_amd64.gz Flag it as executable chmod +x govc

End-to-End SSL certificates between CDN and the VPS Migrate from docker-compose to ansible for easier rebuild of the site. Overall, happy with the results.. and with that said, I’ll create a more detailed steps on the learning from this and what you can do with

(this true with the current version: NSX-T 2.5.1) Anyway, here are the steps on how to configure: Manager / Edge Nodes: SSH to the Management IP. I’m using root Switch to admin to start working with NSX CLI (cmd: su admin) Issue command: set-loggin

I was with a GSS Support today troubleshooting NSX issue on one of my engagement. He did a packet trace from ESXi hosts to see if there is traffic leaving/ entering the physical NIC which really nice. This will be helpful in establishing if the issue is somewhere in the environment or not. Here’s the command Receive: pktcap-uw –uplink vmnic0 –capture UplinkRcvKernel -o -| tcpdump-uw -nr – Send
