QEMU VM with tap interface sees all packages coming from hypervisor instead of real source IP
in flag

I have set up a very simple Hypervisor using Alpine Linux and my VM sees all traffic coming from the IP of the hypervisor.

Which also means if fail2ban tries to block attacks, it always blocks the hypervisors IP

How can I have the VM see the real IP Adresses and not just the IP of the hypervisor?

Does Throughput calculated adds up using multiple (all active) physical adaptor
pk flag

I had a network adaptor of speed 20Gbps. By stressing this adaptor using one of benchmarking tools (netperf is the tool which I used), I was able to get ~18Gbps which is well accepted.

Now, after installing one more adaptor of the same speed i.e. 20Gbps, and stressing both adaptors using the benchmarking tool, I was expecting ~36 to ~38Gbps. But still able to get the same ~18Gbps.

Does this mean, th ...

Error trying to ban ip addresses from apache with fail2ban: Sorry but the jail 'apache' does not exist
us flag

I want to use fail2ban to block specific ip addresses with:

sudo fail2ban-client set apache banip 111.111.111.111

I get:

 NOK: ('apache',)
Sorry but the jail 'apache' does not exist

I'm also confused because the jail.conf file does not contain an entry for [apache]. I tried adding it manually and restarting fail2ban. That didn't help.

All the tutorials I've found talk about the [apache] jail but it ...

Is it possible to set a Default App on Server 2016 being used for RDS that isn't installed on the server?
ax flag

I have an RDS server setup to run a single LOB app remotely.

This LOB app has links to documents like .msg files and .pdf files. When a user running the remote app tries to open a file via the remote LOB app, it's looking to the server to see what the default program is to open that with.

For PDF's this isn't a big deal. I have Adobe Reader installed on the RDS server and on the local machine, and ...

Troubleshooting opaque Cloud Run 502
cn flag

My Cloud Run app responds with 200 on most requests, but certain HEAD requests throw 502. When I run the Docker container locally it consistently returns 200.

Even my in-app access logs say that the web server has returned 200, yet I get 502 from Google Frontend. No other messages are logged between the in-app access log's successful response and the failure from Cloud Run.

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.
