Reject mail based on FROM domain
tr flag

I'm wondering if it's possible to setup filter in sieve to catch the FROM domain and match that with the TO recipient mailbox name.

Usage is to filter unwanted emails when companies sell/share my personal information.

ex.

This should be accepted:

FROM: [email protected]
TO: [email protected]

This should be rejected:

FROM: [email protected]
TO: [email protected]

Best AWS service to host a software that can listen on the given ports
pk flag

I am looking for the correct AWS service to use to host a software.

The software itself includes modules that acts as a mini server, the users can start the module and then it will listen on the given port and should be accessible externally.

Currently, I am using AWS Ec2 to do it, as it allow me to open all the ports 0-65535 and it gives the public IP too. I am wondering if there is any better and  ...

Nagios on a virtual network
us flag
Jul

I am trying to emulate a virtual network in Kathara (ex. NetKit), based on OSPF and BGP routing and I am new to this. After emulating the network I need to monitor it using Nagios, but my question is how is it possible? My virtual network is running on an Ubuntu distro, do I need another virtual machine where I should install Nagios, or how does it work exactly? I am new to these technologies and I don' ...

History:

We moved a Codeigniter 3 Installation from Bluehost to a T3.2xlarge. That single instance is hosting apache2 and a mysql server as a local database.

On Bluehost, the instance was running fine, migration was done since Bluehost itself had outages and we wanted more reliable hosting.

Since the migration the Page is randomly going down completely. Trying to restart apache2 with:

OpenVPN AMI instance - routing doesn't work
us flag

I have an OpenVPN AMI instance and an Ubuntu micro behind it on AWS. The configuration is correct when I use NAT on OpenVPN. I can reach the Ubuntu micro through the tunnel and I have NAT gateway configured for that server. The OpenVPN configuration allows only the VPC traffic to go through the VPN. However, when I switch to Routing, I cannot access the Ubuntu micro any more. I've done the following:

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.
