Does pi-hole address this with it's Deep CNAME inspection feature?

Looks like the answer is yes. This is how uBlock Origin's works too.

Good question, I don't know.

Apparently uBlock Origin in FF does, but not in Chromium based browsers because FF has a DNS API, and the others don't.

Have you guys seen this?

https://www.theregister.com/2021/03/04/adguard_cname_tracker/

AdGuard on Thursday published a list of more than 6,000 CNAME-based trackers so they can be incorporated into content-blocking filters.

CNAME tracking is a way to configure DNS records to erase the distinction between code and assets from a publisher's (first-party) domain and tracking scripts on that site that call a server on an advertiser's (third-party) domain. Such domain cloaking – obscuring who controls a domain – undoes privacy defenses, like the blocking of third-party cookies, by making third-party assets look like they're associated with the first-party domain.

This blurb doesn't do this issue justice. Because of the use of CNAMEs, the third parties now appear to be a first party subdomain, as such our browser sends them our session cookies for the sites in question.

This is a pretty scary security issue in my opinion.

He's assuming a 9 pin serial port...

Hence specifically why I pointed out that assuming RS232 meant a specific port was a myth. I addressed exactly that!

I realize you addressed that, but you didn't get him to the answer he needed, not in that one post, the followup post was closer.

Yep, that should do you just fine.

Now the question is - what are you going to use to terminal connect to the com port? Windows used to have a TTY session on it - back when modems were common, but I think that was dropped ages ago.

You can you PUTTY, that's probably the easiest way to go.

If you want to hassle with WSL, you can follow these instructions to get a terminal that will connect to the com port.

Others might have more suggestions as well.

My laptop does not have a serial port. So do I need some type of adapter for it to work?

It does have one, USB is a serial port. (That's what the S stands for.) RS-232 is a signaling standard, it doesn't denote the adapter. That's a common myth (that the A+ liked to repeat a lot.). USB and RJ45 are the standard connectors for RS-232 for the last many years.

Sigh!!!!

I hope you seriously don't think this answers his question - He's assuming a 9 pin serial port...

Yes you need a USB console cable, not a 9 pin to RJ45 cable - or you need a convertor - 9 pin to USB.

*Edit - I do see you sorta kinda addressed the USB in the second post.. but still.

I grabbed a console cable from Micro-center, which luckily was down the street. I’ll try these steps and see how it goes. I started working for this MSP about a month ago. Very challenging, but also getting exposed to different environments.

Nice - welcome to ML.

@Fredtx Is there a reset button on there?

There’s a “mode” button.

Using the Mode Button

Using the Mode button (see Figure 2) you can:

Reset the AP to its default factory-shipped configuration
Clear the AP’s internal storage including all configuration files

To use the mode button, press, and keep pressed, the mode button on the access point during the AP's boot cycle. Wait until the AP's status LED changes to Amber. During this, the AP console shows a seconds counter, counting the number of seconds the mode button is pressed. Then:

To reset the AP to its default factory-shipped configuration, keep the mode button pressed for less than 20 seconds. The AP's configuration files are cleared.

This resets all configuration settings to factory defaults, including passwords, WEP keys, the IP address, and the SSID. However, the regulatory domain provisioning is not reset.

To clear the AP’s internal storage, including all configuration files, keep the mode button pressed for more than 20 seconds, but less than 60 seconds.

The AP's status LED changes from Amber to Red, and all the files in the AP's storage directory are cleared. This also removes any regulatory domain provisioning made previously.

If you keep the mode button pressed for more than 60 seconds, the mode button is assumed faulty and no changes are made.

This doc seems to be a starting point.

The features of the 1830 series access points at release are:

Supported mode(s) of operation:

Supports Cisco Mobility Express solution. The 1830 series access point can operate as a master AP (having an integrated wireless controller functionality) in a Cisco Mobility Express network. For more information, see the Cisco Mobility Express User Guide at the following URL:

Looks like you can have a master AP, not sure if all 1830's are the same, of if you need a specific model to do that?
