Obtain Let's Encrypt SSL Certificate for Internal Server on Internal DNS Server
us flag
Joe

I currently run an organization and we use a internal website that is hosted within our network that runs a Gitea Server so that we are able to access important documents without having to rely on a third-party service.

I have already setup a DNS server using MaraDNS that routes to the proper IP address. We also run additional applications on this server (such as an internal REST API) but have been cur ...

Will using a private VPC for a MongoDB EC2 reduce latency?
in flag

I'm currently using Lambda functions to access an EC2 instance in the same region as the Lambda functions (us-east-1). The EC2 instance is currently accessed via a public domain (e.g, mongodb://services.mydomain.com/etc?ssl=true) with SSL enabled. Any database requests must therefore traverse the public internet.

I'm wondering how much I can expect to reduce latency by putting my Lambdas and the  ...

Increase memory usage on NFS Server
kw flag

I'm producing data (100GB files) that are finally copied to a server through NFS v4.2, on a 10Gb network. These files are stored on many HDDs, with XFS formatting (one copy per target drive).

When the copy tasks are running:

  • There is a huge memory usage on the client (could be more than 64GB, it takes as much memory as it can).
  • But almost no ram is used on the server.

I would like to reduce the memory u ...

port forward only for vpn clients on draytek vpn router
ru flag

I have a VPN server set up on a vigor 2865. I now want to allow one external ip address, or anyone connected to this vpn, access to a website on an internal server. This website uses a public dns name to resolve to my public ip address. e.g. mysite.mycompany.com

If I port forward 80/443 to the internal server then anyone can access the site. This works fine.

NGINX proxy_pass host resolution inconsistent with IP6
us flag

I'm using NGINX in a simple reverse proxy scenario, usually with a variable to define host names so that it won't fail to start if the host is unavailable.

Here's what I find: With this configuration traffic is proxied, but the pages don't render completely - it looks as if some of the .js libraries aren't loading.

IIS leaks internal IP with an HTTP/1.0 request without a Host header
fi flag

A security scan of our IIS 10 server revealed that it's disclosing the internal IP address of the server via the Location header when a request is made to a folder, such as https://example.org/Content. This generates the following (xxx represents the internal IP):

HTTP/1.1 301 Moved Permanently
Cache-Control: no-cache, no-store, must-revalidate

How do I fix "No usable signing certificates are available" in VBA?
ne flag

We have a VBA script in Outlook that generates a popup when sending external emails. Apparently the script's signature expired over the weekend. The person who signed it is no longer here. I see the certificate in the CA on our DC but no option to renew.

I've generated a code signing cert and imported it into my computer but the VBA editor keeps saying No usable signing certificates are available

How to query linux kernel which storage-related operations are currently being run on the level of FS / block layer / SATA controller?

Every once in a while, our Linux LAMP server (using PHP-FPM, XFS on thin LVM on HW RAID, Centos8) becomes inaccessible and stops responding to HTTP(S) requests.

Via centralized logging we found out that in those cases, load average quickly shoots up to hundreds, while more and more processes (systemd-journald, php processes, kernel xfs/dm threads...) get into a D state. According to iostat and pi ...

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.
