Can't connect to sendgrid from server (and iptables woes)
cn flag
Oli

I'm getting timeouts when using telnet smtp.sendgrid.net 587 on my VPS, but it works fine from my local ubuntu station..so I think there's some firewall issue.

I have a docker setup (yes that has some security implications with iptables) on my server, and tried opening outgoing traffic to port 587, but it's not working. I tried UFW first, but that was confusing as Docker opens ports and UFW says they ar ...

How to enumerate/scan for private dns subdomains through a VPN connection
in flag

I need to enumerate/scan a target IP address through a VPN on a private network. The target has an apache web server on port 80. No DNS server is available for the target since it is on the Hackthebox network. So far, all DNS entries have been made through the /etc/hosts file. There has to be a better way. I've looked online for tools like dnsmap but they only seem to work on public DNS. I need somethin ...

I have recently acquired a HP Proliant DL380e Gen8 + a storage array.

Need to utilize the Storage array as just a bunch of disks, preferably with TrueNAS and ZFS for inter usability, if the server dies we just replace it and not spend days trying to get data back and find different raid/smart arrays

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.
