That book goes with the website. I think you'll find it's the same author.

TIL that airlines will only do social distancing on flights with open seats. Am I ready to get on that plane again?

:no:

After seeing *that* news story, I made up my mind that I'd rather spend 2 days driving to the client site than 1 day flying.

TIL how to create and deploy resources in Azure.

While doing so I had the idea of deploying a virtual machine where I can run GNS3 so I don't have to keep investing in hardware. Will have to further research exactly how much that would cost, do a comparison, and figure out if I could even import my IOS stockpile into it.

TIL that you can't duplicate hostnames in DHCP reservations in Linux. I am adding DHCP to a subnet that has always just had statics. I grabbed the ARP table, and did DNS lookups for all the IPs. If there was not DNS I marked it as "unknown". Added these all as reservations to dhcpd.conf, and it wouldn't start. Now all the hosts are unknown_ip.address.

TIL.. "91.3% of malware uses DNS yet 68% of organizations don't monitor it." According to Cisco anyway.

and a lot of that DNS is easy to spot if you just look. It isn't as easy as bad-malware.com, but it usually isn't that hard either.

TIL how to use a freeware utility to spoof my MAC address on Windows. And then that Cisco switches just delete the inactive duplicate MAC address from their tables so as not to create a conflict.

TIL single mode fiber is really cheap now. Might finally be able to make the case to do our new cable plant 100% SM. Get rid of the OM3/4 stuff. The server guys can reuse all my old optics and patch cables for their servers to top of rack.
