how to test speed of DNS requests
by SaintDanBert from LinuxQuestions.org on (#6EKCE)
Q1. Can someone tell me how to test and diagnose issues with my home LAN?
I think that it is a DNS problem, but I have no clue how to proceed.
Q2. What information might I post so that my LQ colleagues are better able to offer helpful suggestions?

The Following events happen during almost every end-user session. In most cases, they resolve after some variable elapsed time.
One "interesting" situation happens. When requesting a web link, we get some web based error report "server can't do that" which almost immediately resolves into display of whatever we were trying to reach.
I notice that 'update-manager' has notified of available package updates.
When I launch the utility, I request a rescan and see the spinner saying that things are working. This continues for quite some time.
I'm in a browser i typicall Firefox or Chrome i and select a link.
I see the spinner saying that things are working. This continues for quite some time.
I receive email with an embedded web address link.
I select the link and see the spinner saying that things are working. This continues for quite some time.
My Configuration:
Code: Fiber to ISP --Z-- ISP Gateway
ISP Gateway --Z-- ASUS Router & Wifi AP
ASUS Router & AP ==Z== Managed Switch( 16 port)
Switch ==Z== CAT-6 House wires
Wires ==Z== net printers
Wires ==Z== Home Servers
Wifi (3-node Asus Mesh)
desktops
laptops
phones
tablets
Smart Home devicesThank you in Advance,

| We see these troubles from every "interactive" device: workstations, phones, etc. I will describe the troubles as I see them from my Linux Mint workstation. I believe that Linux will offer the broadest set of LAN test and diagnostic tools and utilities. |
