This needs saying occasionally: NAT is needed when going from private IPv4 to public IPv4 •if• the traffic is going to a place where we don’t control the routing. If it’s within our routing domain, it’s 100% optional and gives us better visibility if we don’t bother. #NetEng

@danieldibswe Even better would be breaking down how cloud networking is just routing tables, ACLs, and tunnels with strange names and software bugs

Upgrading from a 2960X stack to a new 9200 stack... and there can't be any general loss of communication during the changeover. This is where a good knowledge of RSTP comes in handy. #NetEng

I just misread “enthusiast” as “euthanist” this morning. Changes the tone just a •tiny• bit there.

First motorcycle ride of the season is complete! (Admittedly, it was a •really• short run to get a couple of bottles of wine, but a ride is a ride.)

Q: What did the IP packet say to the Ethernet NIC? A: You’re trying to frame me! #BaDumTiss #HereUntilFriday #TryTheVeal #NetEng

Lots of people dismiss products and solutions that don’t fit into a loosely-defined “enterprise grade” category. It’s amusing that many of those folks support organizations that don’t easily fit into the (equally loosely-defined) “enterprise” category in the first place.

An application failure is evidence of an application problem, not a network problem. If you want to blame the network, demonstrate that it’s the network. Your application doesn’t provide enough information to do that? This is just more evidence of an application problem. #NetEng

Is it just me or has “under promise, over deliver” slowly been turning into “under promise, over charge” of late?

Once again, my social media handle proves to be well-chosen. Walked into a customer site today, swept my access card, and was challenged by the receptionist. I told her who I was and she called my contact to verify my identity (good on her) anyway. #KnownByMany #SeenByFew

Hmm… signs I’ve been doing this for a while. Someone was talking about a SOC service and I heard SOCKS service. #InfoSec

“The customer got a ‘host could not be resolved error’ so we told them to just use the IP address instead.” Gah! How hard is it to add an A/AAAA record? Really?

I usually settle on IKEv2/IPSec for connectivity over the Internet. I'm familiar with it, it's quick, and (mostly) interoperable across platforms. That said, there are days when I'm 100% convinced that these sentiments are the results of Stockholm Syndrome. #NetEng #InfoSec

I've had two people (obviously Windows users) pronounce traceroute as trace-ert today... and it bothers me. It shouldn't, but it does. 🙂 #NetEng

Folks love to shorten things to generic prefixes figuring that others’ uses of the prefix are anecdotal. Dr of Cyber is the most recent I’ve seen. Guess what? It’s not short for Cybernetics. Crypto is more than cryptocurrency. Trans is more than transgender. Clarity is important.

Things I learned today: When running a packet capture on a @mikrotik_com RouterOS device, a capture started on a disabled interface will not capture even if the interface is enabled afterwards. Enable the interface and •then• start the capture. #NetEng
