Is it possible to deploy 2 TLS certificates on a server at the same time?
gb flag

I created CSR and asked my organization's internal CA team to generate a certificate which I then deployed on an internal server. However, the clients connecting to this server did not trust the certificate so I needed to add the key signature to the clients' Java key store using the keytool utility.

Now, this certificate is about to expire in a couple months time. Is it possible to have two certificate ...

mdadm how to use an array as a "member disk" in another array
se flag

I HAD a 4-disk RAID 5 array with MDADM. One of the disks failed. I bought a new disk three times the size of original disks as replacement.

I now have

  • 3x5TB disks in a degraded RAID5
  • 1x16TB disk free unused

I want to change the existing raid from 5 to a-sort-of 1+0 where only the old disks would be the "0" part:

  • 3x5TB disks in RAID0
  • 1x16TB disk

The above would be assembled in the RAID 1 I want  ...

How do I make my reverse proxied Nginx server access other routed files in an express app running on port 3000?
it flag

Currently I have an express app inside /usr/share/nginx/myexpress

The express application is listening and working perfectly on port 3000. My NGINX server is reverse proxying to it and I can view the default express page by going to kodix.com.br.

The problem is, I can't go to kodix.com.br/hello for example after routing it. I can only access it by going through the ip address. (Like this example but with  ...

VMware vSphere: Change the IP that vSphere sees/reports without changing the IP configured in the guest OS
cn flag

I have an integration that attempts to use the IP that vSphere detects for a vm guest, but sometimes the IP that vSphere detects is not the IP that the integration should use. The most straightforward example is where the the guest's network traffic passes through a 1:1 NAT (each guest has a unique IP after passing through the NAT, but it is a different IP than the one vSphere sees) prior to being seen ...

WonderShaper limits the bandwidth too much
fr flag

We use WonderShaper as a traffic control tool on our linux servers. We have 10Gbit uplink, and I want to limit the upload and download to be up to 1Gbit per server. My goal is to prevent a situation in which one server downloads a huge file and chokes the whole line.

All I need to do is to define what is my required upload and download bandwidth (kb) -

Centos 7 Samba php:apache Permission Denied when moving file with Docker container after moving to :z volume from samba share

First, let me say that chmod 777 does not even work for this (though I know that would not be the correct solution).

Here's the situation: I have a mail server receiving mail. On that server there is a cronjob that runs a .sh script that moves the mail files to a samba share. A separate app server (which is where I'm having the problem) also has a cronjob that runs a .sh script that moves thos ...

Windows Long Filepaths Registry Setting

Just a quick question for something, I can't seem to find out about online. When enabling the LongPathsEnabled registry value by setting it to 1, does this require setting on the client computers, the server hosting the file share or both?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

LongPathsEnabled = 1

My understanding is that this will only allow certain apps to save files with l ...

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.
