Trying to copy files from one server to another because the amount of files is not feasible to do by copying to my home pc and then out to second server.

SSH, rync, and scp all hang from either server, but works fine to log in directly over SSH either from web terminal or from putty over SSH.

Clicking a Google query link logs user out of session
jp flag

I have a curious situation with my NodeJS server: it seems like searching for the website on Google signs out the user.

The homepage is https://emocoes.org/pt/inicio. I sign in to the website and the homepage shows the version for users, such as a "Content list" button.

I open a new tab, search for the website on Google and click the link. Now the homepage no longer shows the version for users. I ...

GRE tunnel. Port Forwarding with IPTables from VPS to Local Server not working
de flag

Dear ServerFault community,

I have an OVH VPS with 3 public IPs (1.1.1.1, 2.2.2.2, 3.3.3.3) and I am trying to forward them individually, with one tunnel for each IP, to a server in my office (IP 5.5.5.5) with port forwarding. This so that I can hide my office IP when running services on my office server.

1.1.1.1 is reserved for VPS's SSH. (All the ports are dropped except for port 23).

I forwarded one IP ...

Need a CLI program to implement cloud level reentrancy protection
fr flag

I have a kubernetes system which must run rake db:migrate before deployment. For reasons, we'd like to do this as an init container instead of a job.

This seems like a more general class of program of "how do I make sure only one of these commands is running at a time, across an entire cloud?"

My thought is to use dynamodb, redis, or similar shared NOSQL solution to implement a lock.

Does anyone kn ...

Serial Line Tester (not just a monitor)

I'm looking for a serial (RS-232) line tester, not just a monitor. I want to introduce delays and errors for test purposes. I can find plenty of serial monitors, but none that have features for testing by simulating adverse conditions. Any pointers?

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.
