Firewall "any any" rules - Should I remove all these rules?
jp flag

I inherited a server from another dev that left. And the hosting is telling me to remove all these firewall rules, because these can cause security problems. Not sure if I'm understanding this correctly, but wouldn't removing all these rules also block users trying to access the websites on the server and even email access?

What is the exact meaning of "On Commit" in ISC DHCP server configuration?
vu flag

I know there are three kinds of events we can use for scripting in ISC dhcpd -- commit, expire and lease. My problem is, I am having a little problem in understanding the "commit" event. I know "commit" event means when the server has made a commitment of a certain lease to a client. But it would be easier to understand this in DORA context.

That means, when the "commit" event will trigger in ISC DHCP s ...

Using ansible loop until with stdout_lines
de flag

I am trying to use ansible loop until the condition is met. I can use until if the output is only single line, however if the output is multiple lines, I will need to use stdout_lines but fail to do so.

If output is single line:

- name: check on sync status
  shell: some command
  register: sync_status
  until: sync_status.stdout == 'SSUS'

If output is multiple lines, then I try to use stdout_lines

Distributing load over multiple load balancers

Given a website that could have many hundreds of thousands of concurrent users at peak times how can one manage the laod where load balancer resources can only support 40,000 concurrent connections? (System spec, out of my control)

Cannot Access Mail Folder Content Since Dovecot Switched From MAIL to MAILDIR During Update

*See UPDATED & UPDATED AGAIN to jump to the issue at hand.

Just discovered that my mail app(s) are not displaying all of my messages in my SENT box(S) and maybe other boxes.

For example when using Mac Mail "Account Info" shows that one of the "Sent" boxes is only 97 KB and contains only 8 Messages but on the server the "Sent" box is 179M and I know contains a lot more than 8 Messages.

Are Windows GPOs encrypted?

We have a piece of COTS software that has a command line tool for server credential rotation. Instead of going to each machine to rotate the credentials with the tool, I would like to use GPO to run a script to do so. However, I would need to place the new credentials in the script, so I am wondering if the script files stored in the GPO are encrypted at rest. I have not found any authoritative document ...

Tom

Is it possible to block any access other than HTTP 1.1 and HTTP/2 on Apache, for all VirtualHosts?

I added the code below to apache2.conf, but I still see IP requests coming via HTTP 1.0

#Block HTTP 0.9
RewriteEngine On
RewriteCond %{THE_REQUEST} HTTP/0\.9$
RewriteRule .* - [F]

RewriteEngine On

Does editing files over SSH transfer them to the local machine?
bz flag

If I were to edit files over an SSH connection, lets say either SSH'ing into the remote and editing files using Vim or using VSCode's remote development feature, are the files actually being transferred to the host machine (even if they are just being held in memory) and sent back after they have been changed? My fairly limited understanding of SSH would say that yes of course it would have to, but I  ...

Internal Access to Published Services: Direct vs Bouncing Off Firewall

We have, as is common, two DNS infrastructures, one for internal resolution and another, non-forwarding, authoritative server for our public domains.

This question is about the comparative merits of two different approaches for our internal hosts to access our public services:

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.
