#netadmin — Public Fediverse posts

2½ Stunden debuggen (bis 4 in der früh), weil meine Docking Station Amok gelaufen ist und das Netz gekillt hat. Und da war nicht einmal ein Rechner dran.

Wer kommt bitte auf sowas, oida?!

"Every time I launder my undies, the washing machine complains that I’m thwarting its dream of joining a global botnet."

The second edition of Networking for Systems Administrators is in progress. Just as the NIC is where the server meets the network, TCP/IP is where the sysadmins meets the netadmins. I'm writing this book to end the feud between these two teams.

If you'd like this book to happen, you could sponsor it. https://www.tiltedwindmillpress.com/product-category/sponsor/ -- 13 more print sponsors and I have to do another challenge coin!

What are people using these days for Netflow/IPFIX collection and analysis? #sysadmin #netadmin

(Yes, yes, I wrote "Network Flow Analysis," but it's IPv4-only and flow-tools is not extensible to IPv6, plus that was fifteen years ago and life moves on.)

How long do you let DHCP leases remain unrenewed (dynamic or static allocation)? Since my entire network is static DHCP, but a reboot of that server wipes its known DNS (I'm working on it), and it's a small home network, I'm in the < 15 minutes camp, and will ratchet down if I know I'm making a major change. Work is usually around 60 when I control it. #sysadmin #netadmin

@me I've been tempted to say I'm a #sysadmin and #storage admin by day, a #sysadmin, #electrician, #plumber, #landscaper, #chef, #mechanic, #netadmin, #coder, #storage admin, #digitalforensics, #electronics dude by nights & weekends.

And, of course, sometimes a #veterinarian or #generalcontractor or whatever else needs doing.

Spent the last few weeks migrating our stack from #vmware to #nutanix #ahv. Went really smoothly except for a few bumps related to our directory servers running server 2022.

Cant help but feel like the product is just a very simplified (even at times dumbed down) #ovirt / #rhv - which was what we were originally going to migrate to before #redhat said the product was end of life.

Maybe simple will be good. At least it's not vmware
