Internet Woes

 I can bet you the majority of the people reading this has run into this issue.

As I’m working on the network design for this new site, I thought it would be a great idea to put the order in for internet for many reasons:

-          Sometimes there is a backlog and your next install date might be weeks away.

-          Even though we pull conduit to the sidewalk, it would be much easier, faster and cheaper to trench since its just dirt everywhere compared to when its finished and you have an asphalt driveway, landscaping, etc.

-          If the carrier doesn’t have your address in their database yet, there is time for them to get the backend stuff done.

 

I wont repeat what I said in the video, but the summary is simple; I called Carrier A since its their fibre and they tell me they cant service our address. So then I called 2 of their competitors who have no issue providing a quote for the install and monthly service..

 

Go figure...

Network Slicing

One of the most important features of 5G is Network Slicing.

Network slicing uses virtualization technologies, especially Software Defined Networks (SDN) and Network Functions Virtualization (NFV), which enable a 5G network operator to provide customized networks by creating multiple virtual and end-to-end networks, referred to as network slices. E..

Changing Packet Arrival Time in Wireshark

 

When I teach, present or use some reporting tools, I like to change the date for many reasons.

I searched around the net and quickly pulled into the python scapy rabbit hole, then I remembered Wireshark’s Time Shift feature. I wasn’t sure what the limits of it was and thought I would try it out.

I took a trace file from 2012 and wanted to change the time to 2022. I went online and converted 10 years to hours and got 87660. I then went to Edit->Time shift and entered 87660:00:00. Done, worked like a charm.
