CNAME (pointing to the same server) asks for credentials
cl flag

Let's say I have two Windows Servers:

  • dc1
  • dc2

And I have a CNAME record:

  • MyFileServer (pointing to dc2)

If I from dc1 opens share \\MyFileServer\c$, then it works fine.

If I from dc2 opens share \\MyFileServer\c$, then it asks for credentials - and no matter what credentials I enter, it fails.

How can I fix it so I can open \\MyFileServer\c$ from dc2?

Binding multiple IP on single listen throws error in HAProxy

I have a LB which is redirecting request in a round robin mechanism to my 4 servers configured. I have assigned a floating IP address(LOADBALANCERFLOATINGIPADDRESS) to the machine.

pfSense - How to allow traffic only to the internet for part of hosts?
de flag

I have computers on my network that I want to allow access to LAN resources - I created an alias with their IP addresses (LAN_WHITELIST). For the other devices I would like to do Internet access only.

So I have also created an alias for private networks: 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 - INTERNAL_NET.

My rules look as follows: rules

That is, I pass LAN_WHITELIST to INTERNAL_NET. I block not LAN_WHI ...

Allocate virtual IP address to installed VM instances in Centos 8 (Cockpit GUI)
ro flag

I have a dedicated AMD cloud server(one network card) with 5 additional virtual IP addresses meant for the installed virtual machines. I used the advised Cockpit GUI to create the VM's.

I can't figure out how to direct all requests from a specific IP to an allocated VM. i.e All web requests to an installed web server vm with IP (xxx...).

Thanks up front

Can't find Amplify access logs in CloudWatch log groups
ge flag

I'm creating a CloudWatch dashboard and I want to monitor Amplify access logs beside other metrics. I can find the access logs inside the Amplify dashboard (Screenshot below) but I can't find the same logs in the CloudWatch log groups. Why is that? should I turn on anything?

Route Specific traffic through Open VPN
cn flag

I use Open VPN to connect remotely to an intranet in a different city on a different network ( but probably with the same subnet ). The intranet is on 192.168.1.42 on the remote server in the office.

We are in an office where ip address 192.168.1.42 is a local IP address and a remote ip address - but I want to force open VPN to use the remote version of that IP Address but keep regular internet s ...

What capabilities do you lose when turning off COW on a qcow2 file?
us flag

I run a small internal cloud utilizing 3 redundant, live migration capable Ubuntu/Qemu/KVM hosts with ~30 mixed OS VMs.

The Pool volumes are BTRFS and before any of you give me crap about it: this is small shop, utility is more important than performance here, so zip-it!

This being said, one still should mitigate the performance issues as best one can. The alternatives are turn off COW at the volume ...

Reject emails that fail reverse hostname resolution
us flag

My Postfix server is receiving spam from an ever changing set of domain names but with a consistent pattern in the log file starting with line warning: hostname X does not resolve to address Y. No legit (ham) email has this pattern so I would like to block emails associated with this message.

Is there a way to block these emails entirely in the Postfix configuration, such as in the main.cf file?

Windows 2012DHCP Scope on a /8
co flag

I inherited a mess. Let's say there is a site in the network setup as 10.0.0.0/8 with a DHCP pool range of 10.100.100.1-254, a subnet of 255.0.0.0 and 10.199.199.1 is the DefGw. All of the IPs within that /8 are able to route correctly. There are static IPs assigned scattered throughout the /8. If I needed to extend the amount of DHCP addresses to accommodate 500 addresses, could I change the end of ...

Mirror Accelerated Parity / NVMe / ReFs / Fast-Tier Issues
ar flag

I'm currently building a lab server with some cheapish hardware. 2 NVMe SSDs, bunch of 3.5 HDDs. After creating a Tiered Storage (NVMe-Mirror & HDD-parity), formating it with ReFS, everything behaves quite as it should:

  • Using performance-counters I can see the fast-tier filling up, then starting to destage to the parity tier, once it hits 85%.
  • I can verify new writes always hitting the fast-tier.

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.
