When should I add multiple network endpoint groups to a backend service?
vn flag

When configuring a Google Cloud Load Balancer, I'm presented with the option to add multiple Network Endpoint Groups to my Backend Services.

A lot of the literature around Cloud Load Balancing focuses on the geographic distribution of request across identical services representing one boundary deployed across different locations.

Google Cloud documentation mentions that serverless Network Endpoin ...

What is the best way to setup a network printer in an enterprise environment?
et flag

As far as I know the printers should get a static IP (with MAC and IP binding) assigned from the DHCP Server (in this case a router) so that the IP is taken from the DHCP IP pool.

An alternative to just setup a static IP on each printer manually got suggested.

Which option is the best? Is there an another option, which is even better?

Can I route using the leftmost portion of hostname with a wildcard for everything after?
vn flag

I have an application where I would like it to forward traffic based on the highest-order subdomain, rather than the full domain from right to left.

So for example, I have the domains:

  • mydomainone.fake
  • mydomaintwo.fake
  • subdomain.mydomainthree.fake

Is there any way that I could make the following all route to the same backend using a single rule like api.* (by way of the fact that they all start with

Return 444 Instead of 400
mt flag

If someone makes an http request to an https resource on my nginx server, they get an error 400. "The plain HTTP request was sent to HTTPS port" Is there a way to return 444 instead?

When I search for this error, I can only find people that have had configuration issues they were trying to fix. But in my case, my configuration is fine - I'm trying to minimize impact of illegitimate requests.

CentOS 8 misses a significant amount of RAM on VPS
us flag

CentOS 8 is running on a VPS having 1GB RAM.

dmesg shows:

Memory: 216012K/1048040K available

So I believe BIOS sees 1,073,192,960 bytes. Then, as free -b reads, RAM has 997,236,736 bytes in total.

That way, we can see a gap 75,956,224=1,073,192,960-997,236,736 bytes. In other words, 72+ MiB of 'unusable' memory.

How to bring that memory back to OS? Or how to learn where it is 'hidden?'

Dynamic Windows 10 AppLocker rules for user groups not working
jp flag

I'm trying to make dynamic app blocking rules with AppLocker. The setup is that I have predefined AppLocker rules (for example, Allow windows user group 'Chrome' access 'chrome.exe' (not actual group name or actual path)) and then assigned users to groups at login with the help of a Windows service.

That worked fine at first, but after a while it stopped (AppLocker itself worked, but user groups specifi ...

QF0

The link is an image of a Wireshark dump of an incoming 60-byte Ethernet frame which contains a UDP packet. The packet payload is the single word 'hello' (sorry, I don't have enough rep to paste the image directly).

Problem: I can't get socat or nc to read and display this packet (this isn't entirely true; see #1 below).

I have an Oracle 18c XE server where there is a corruption in the system01.dbf file of the main XE database.

All user data is in a PDB database which luckily seems ok (the PDB is working in production now).

The problem is that I can't make a backup of the PDB with expdp, because expdp fails with this error:

is there any deployment automation software that can create an encrypted vm in esxi?
cn flag

I recently felt the need to encrypt my esxi vms and tried to find some way to do it with terraform but couldn't find an option for that in the documentation so I looked into ansible , chef with no luck. So my question is that is there anyway I could create an encrypted vm or encrypt an existing one using automation other than the vmware vsphere api since that thing is a mess.

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.
