Route only some traffic through different VPNs
ve flag

In my work, I have quite a few different external networks that I need to access from time to time via VPN. Generally I need to connect to somebody else's managed network to access their Building Management System (BMS) so I am at the mercy of however they set up their network access - this usually involves juggling various assigned logins and having to re-enter the credentials everywhere I go.

How to setup ingress with ingress controller in a separate namespace for redmine in k8s?

I am a tad new-ish to k8s and trying to set up Redmine on Amazon EKS cluster using Traefik. I lack a tad of understanding as to how the controller will pick up the ingress, especially given that the ingress is in the redmine namespace and the controller resides in it's own namespace. Below are my settings: Traefik Ingress Controller:

Is there a risk for HDD being loosely packaged for transportation?
ke flag

I have received two HDDs (for a NAS) in a loosely package and not really sure if it is safe to keep them. My concern is that they might have been damaged during transportation. Although it doesn't seem particularly dangerous to me all major manufacturers say it is inproper packaging. Do you think there's a risk or they should be just fine?

Modify BIOS configuration on several computers
ax flag

I have quite a few computers that I need to modify some parameters on the BIOS (American Megatrends v.5.12). Is there a way to save this configuration (to a pendrive, for example) and load that on the other computers? or maybe even modifying via network or on the command line?

Iptables + telnet not blocking ports

I have a Debian server from which I want to block all incoming and outgoing ports (especially all outgoing email ports), except those that I specifically add in iptables. The current setup I have is working and seems restrictive enough, but when I start up a telnet session to test for example port 25 for smtp it just seems to connect without problems, even though I did not specifically open port 25 a ...

In Apache2, how can I can the file contents for an index.html in subdirectories when I do not explicitly request it?
cn flag

For blarg.com This is the tree under the document root:

/index.html -/foo/index.html -/foo/bar/index.html

If the request is for 'http://blarg.com' then index.html is returned without issue.

However, a 404 is returned when the request is for '/foo/' or '/foo/bar'.

A response 200 is returned for '/foo/index.html' and 'foo/bar/index.html'.

This is the configured directive:

ISC DHCP/DDNS setup: Static entries for non-dhcp clients
us flag
dom

I have set up a local network with ISC BIND9 and DHCP service. New leases trigger the DHCP to add an A and PTR record which works perfectly.

I also added lots of static host entries in the dhcpd.conf. Now I noticed that the DDNS update only works for clients that actually request a lease from the DHCP server. I have a few devices in the network that do not support DHCP. I still added static entries in t ...

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.
