ip link add test_team_slave type team_slave - RTNETLINK answers: Operation not supported

Trying to set up teaming on a Crux Linux with a custom kernel. I have teamd and teamdctl already installed on my system, I managed to find kernel modules for teaming and successfully enabled them. Tested it by running ip link add testTeam type team, which was failing before rebuilding the kernel. Right now I have issues with the team_slave type, and I can't find which module I am missing.

What's the deciding factors of the number of tcp ack packages for a tcp data-transmission request?
cn flag

I encountered a counterintuitive phenomenon that the rtt(Round-Trip Time) of request from client to a low-network-latency server(ServerL) is higher than the one from the same client to a high-network-latency server(ServerH). The interaction between server and client is quit simple: Client just sends a large bytes stream (1~2M bytes) and server accepts all the bytes and reply a simple ok return code.

I use gitlab, gitlab-runner, sonarqube, nexus, ... with docker compose to test build chains before implementing them on my company's servers. These servers use the same network bridge.

This worked fine on my old ubuntu, but since I'm using debian, containers on the default bridge can't connect to the docker compose bridge anymore.

Since this is not an operational instance of docker, how can I disabl ...

Need help in Moving files to the backup directory except the last 10 files based on file NAME not date modified
gb flag


I have a situation where a server is creating journal files (MJ00001-MJ000x) and I want to move all the files to a backup directory but need to keep the last 10 in there to get the archive. I looked at robocopy and Powershell Move-Item but the problem is the date modified is always the current day as the server looks to them if they are in the directory (hence I can't use move keeping last 10 based ...

Cant access localhost from another device despite opening port on firewall

I am trying to access a simple web server on my main machine from my phone. I got my ipv4 IP and opened the port on the firewall, yet I still can't access the port! I just get a timed-out error on my phone. I checked if both devices are on the same network, and they were. Does anybody know any other possible causes of this?

OpenWRT allow IPv6 access LAN host from the Internet
cn flag

I'm new to IPv6 and trying to figure out how to properly configure my router so that I can access a web server through OpenWRT from the Internet.

With IPv4, I use port forwarding. For example, forward port 8080 of the WAN interface to 192.168.1.123:8080. This way I can access the webserver using my public IPv4 address at port 8080.

With my rudimentary understanding of IPv6, I assume I can have OpenW ...

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.
