Microsoft Teams: Custom Background Images

KB ID 0001669 Problem With the current lockdown and everyone working from home, I’m using Teams a lot. I use one of the images that I use here at PNL as one of the background images that ‘appear’ behind me when I’m using the webcam in Teams. I was asked today how I did that, so I thought I’d write it up here. Solution I’m using Teams on my MacBook but the procedure it pretty much the same in...

Cisco ASA: Mixing TCP and UDP in Object-Groups

KB ID 0001668 Problem I like object-groups, they can make your firewall configs a lot smaller/neater and if you need to add a host, network, range, or port, then you can simply add the new requirement to an existing group. But what if you want to allow both UDP and TCP ports, you can create a service group for TCP and add the ports and a service group for UDP and add the ports, and add them into your ACL where you would expect ports...

Brocade Switches Getting the Serial Number

KB ID 0001665 Problem If you have fiber channel switches, (regardless of the vendor,) scratch the surface and underneath it’s probably a Brocade. (Unless it’s a Cisco Nexus then you are in the wrong place my friend, move along!) e.g an HP StorageWorks 8/8 SAN Switch (Yeah it’s a Brocade 6505), or an IBM SAN24B-4 Express Fabric Switch (you guessed it, Brocade).

OVA / OVF Deployment Gets Stuck ‘Validating’

KB ID 0001664 Problem I had this problem (on sphere 6.7) the other day when trying to deploy some OVA files on my test network. Solution Well as stated elsewhere I tried reconnecting to my vCenter using its FQDN, this didn’t solve the problem, using Flash or HTML5 didn’t cure the problem either. What did cure the problem was using a different browser! I switched from IE to Chrome and it worked fine. Related Articles,...
