So, it’s been a while since I’ve just talked or thought “out loud”. But, it’s been about five years since I’ve been in school. So, I’m considering taking my notes from school and posting them on here.

Summary

This is an old thing I came across. But, useful to know all the same. This post discusses some issues with devices such as Cisco routers, switches, etc. where the key exchange algorithms and host key algorithm types are weaker and/or riskier key algorithms. These algorithms are considered legacy options that may need to be specified when connecting to the host.

Summary

This post contains some notes for switching a Cisco switch over to a different DNS server. Specifically, I will be adding, removing, and testing within the process of moving over to new DNS server infrastructure.

Summary

Notes for configuring DNS servers and search domains for name resolution on Cisco switches.

Summary

This post contains notes for configuring NTP on ESXi 6.7.

Summary

This is just a some notes on how to copy the running configuration to the startup configuration on a Cisco device. This could bean anything from a Cisco Router, switch, etc.

Summary

Needed to add some DNS configuration to some ESXi 6.7 servers in a lab. I’ve never done this. Nor did I have access directly to the console at the time. So, I decided to SSH into the console and use the esxcli command to do the work.

Summary

Needed to change DNS servers from one to the other within my lab on ESXi 6.7. Needed to do this because I’ve been isolating network resolution to my local network as opposed to pushing that traffic to the Internet itself.

Summary

Just some notes. I have my days where I do this a lot. But, just in case I don’t and forget down the road. Might as well have this available.
