Multiple domains on google workplace and email should be added as secondary or alias for email outreach?
in flag

We are setting up our outreach management for a new startup.

The app primary email domain is something like app.com

Emails we send out will be via a new domain, something like app-email.com.

We use google workplace, adding another domain is ok but we can either do so as a secondary or alias domain. An alias is best for our end as all emails will be in 1 inbox.. but this might not be the best overall. ...

Q: Arista, can you read spanning-tree status via SNMP
ie flag

Is it possible to use SNMP to read the spanning-tree status from Arista switches?

Although it is possible to set up SNMP traps for spanning-tree, I did not find anything related to spanning-tree in the Arista SNMP MIBs list, or any mention of the possibility of querying STP status via SNMP in the documentation.

We have several models, in case that is important (DCS-7050T, DCS-7050QX, DCS-7060CX)

Active Directory/LDAP replication Windows/Ubuntu

I am trying to setup replication between a Windows AD and OpenLDAP on Ubuntu.

Access to the Windows AD server seems to work OK, the OpenLDAP on Ubuntu also seems to work, however I am getting stuck on setting up the replication between both - I am new to AD/LDAP and there might be some concepts I'm missing.

I am able to list users on the remote (Windows) AD:

I would like to allow OpenVPN users to reach all Docker containers that are part of Overlay network as if they were in the same LAN. The simplest example is 3 containers distributed on 2 hosts, and the hosts are connected through overlay network, and all 3 containers are part of that overlay network.

For that, I have prepared one OpenVPN container (OpenVPN in bridge mode with TAP adapter), and in ...

Do DNS queries reveal full URLs?

I use my ISP's DNS, which means that if I access "example.com" they will know, but will they know the exact page? (eg. "example.com/something.html"). As far as I know, if I access "google.com" or "google.com/search?q=my+isp+can't+see+this" my device is only asking for the ip of "google.com" in both cases, thus ISP or 1.1.1.1 or whatever... will not be able to know exactly what i'm accessing, instead th ...

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.
