Recommended way to ping from within container
dk flag

Recently I was configuring some containers with non typical networking settings (at least non typical for me) and so I was having some problems (finalny I was able to make it working so no worries). One thing that was making "debbuging" harder was that many public images doesn't contain "ping" util, and this is normal for building docker images (policy "less" is better).

In case when container ha ...

How to benchmark and analyze a network protocol prototype?
pf flag

We are currently working with an academic network protocol that modifies and partly encrypts IPv6 packets and establishes circuits to allow sourceless routing.

We got the prototype running, and it works with IPv6 messages if we put the message payload directly in to IP packet payload (e.g. send a hello world). We can, however, not use well-established tools as ping or iperf3, as the messages rece ...

Force all traffic through vpn
nl flag

Goal: force all traffic through VPN only.

Client: Windows in VM VPN: OPENVPN

I delete the 0.0.0.0 route in the client. I make a route for the destination of my VPN server with my LAN default gateway as the gateway (192.168.1.1). So, in practice when I turn on openvpn, it attempts to connect to the server IP which has a route through my local LAN gateway, which would result in a connection and a new  ...

I am looking for the simplest way to share a single file in a high availability way between a pair of linux servers. (Version and distribution are unimportant, I'm looking for a generic solution.)

I have two servers, each with their own local disks and NFS shares and other services between them. I have a file that both servers need to access, but nothing other than those servers needs to access ...

I have created a backup using mysqldump --single-transaction

I have then restored that on the replication server. I have then enabled replication, but I have accidentally clicked Reset slave in phpMyAdmin and its set the position back to basically 0.

So if my understanding is correct, it's trying to rebuild the DB on the replication  ...

Nginx with rtmp module and ffmpeg adaptive stream is not creating master dash manifest
in flag

I have a working setup of nginx with the rtmp module working like a charm creating live streams with both dash and hsl. No problem so far.

When I try to enable ffmpeg transcoding for adaptive streaming, it creates the hls version just fine, the video chunks, a m3pu8 for each video version and a master m3u8 that is the one I call from the web player.

But in the dash version I get the chunks, the mpd  ...

How can I determine if Microsoft Patches are recommended or optional without using IUpdateSearcher?

On a single computer, it's simple enough to filter which updates Microsoft deems important by running a PS script such as the following:

$searcher = $session.CreateUpdateSearcher()

Was AWS, Bitnami, NodeJS and MongoDB vulnerable during 2021?
jp flag

One user reported that their email and password on my website had been compromised. The website runs on NodeJS and MongoDB, with passwords salted and hashed. It has a front-end only, with little user content sanitized and never shown, and connection to the server secured by public-private key and IP address restrictions. The probability of a hack is very little and could have happened if MongoDB or Node ...

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.
