First of all, I apologize if I misuse terminology here. I work as FE developer and this area on networking and setting up domains and aws services is really not my strongest. I took this task as a good chance for learning.

tcpdump output has a different hostname
br flag

Sorry in advance for the simple question, but I'm trying to educate myself on tcpdump and networks.

I'm tracing all traffic going to a certain host with

tcpdump -SX -i any dst host host.site.com

However, in the tcpdump output I see a different domain printed out, something like edge-123.site.com.

I pinged both URLs and they have the same IP, so that's the traffic I was querying for.

Samba 4 and Windows "Local system account"

I have a AWS EC2 Linux instance with configured samba (v4) shares. The idea is to allow passwordless access to the shares from the onprem machines which are running Windows Server 2016. There are ACLs between AWS and onprem equipment and are working as expected.

I'm forwarding email from my G Suite domain to an Outlook.com email address. This worked perfectly fine until earlier this month. All forwarded emails go directly to junk, because SPF is failing.

For example: grouponmail.nl -> G Suite -> Outlook.com. In Outlook.com the email headers are:

network issue with wsl2, nslookup works, but ping fails

I am facing bad network issue with networking on windows10 machines.

tried most of the solutions available over internet. yet there is no solution.

Solutions tried -

  1. Solutions related to enabling HyperViser and its virtual switch.
  2. Solutions related to resolve.conf

The strange part is, nslookup works for same domain, but ping and telnet fails.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
