Attach port to domain name
id flag

I run a small (centOS 7) mail server at home and I would like to attach ports to a domain name instead of opening up for every incoming connection of the server-IP. Currently, when I open up port 25/993/587 in FirewallD, it opens up to everyone. So when I point a domain name to my server IP, all ports will be opened up. I currently use mail.example.com, but what I would like to achieve is:

Correct way to modify systemd timer
th flag

I want to know the correct way to modify a timer.

It happened to me that I have timer X configured to run at 8 PM daily, modified the job to run at 1 AM, also daily. When executed the daemon-reload the service that it points to was executed even the timer doesn't shows that it was triggered.

Is there a possibility that when reloading the timer the service got executed by default?

Xinetd listen to IP Address not assigned to an interface
is flag

Is it somehow possible to use Xinetd (or any other solution) to listen to incoming Packets for an IP Adress which is not assigned to an interface, and start up a daemon (like Xinetd) does?

So my Linux Machine is the default GW, all Packets are sent to it. I would like to recognize specific packets with a destination IP, which is not bound to an interface and react to it (start up a daemon)

Thanks! ...

Ansible: filling a template that contains immutable interpolations
au flag

I need to make a playbook that will take a template file, interpolate some variables and put the resulting file to another directory.

The first part of the problem is that the resulting file will be used as another Ansible playbook, so the source file contains other interpolations and these interpolations must be preserved as they are. As an example, let's assume that the source file contains som ...

Access denied when listing Samba shares

I've installed Samba to share files with Windows 10 machines. The setup works correctly to access individual shares using their path such as \\myhost\sejf, but listing shares on \\myhost fails with access denied. I tried to investigate various possible options, but with no luck. I have a very similar setup on another machine (Raspbian) and there I have no issues, so I suspect it might be somehow r ...

Clamav is very slow with tcp
in flag

I'm using clamonacc on my desktop computer and servers. I use a raspberry pi as clamd server. The clamd process only uses ~25% of all 4 cores so with htop I see it's using like ~100% and 400% is the maximum a process could use because the raspberry pi has 4 cores. RAM isn't full and there isn't much i/o wait (according to htop)

I'm currently testing clamonacc on one server but the clamonacc queue ...

Mysqld: status_output has automatically turned itself on, spams gigabytes into error_log files

Mysql 8.0.21-12 on linux

Those two flags have automatically turned on with my database server.

  • innodb_status_output_locks

That caused gigabytes of logfiles, I thought the server is having issues so I restarted it.

It started up with the two flags on again. The config file does not contain them (neither on nor off) and I've had the server running for a year without those logs and wi ...

Enabling the elasticsearch token service without enabling TLS

Tom

I've got elasticsearch and kibana running in docker containers, on an isolated docker network. The only port that is "exposed" is Kibana's (unencrypted) web interface. And this is only exposed on localhost; there's an nginx instance in front of it providing HTTPS service, reverse-proxying Kibana.

Now I'm trying to secure it. I want to tie Kibana logins to our OpenID provider. To do that, I ne ...

Many linked tables in a NoSQL? Tons of connections, but only 1 master?
ph flag
Fly

My company uses a NoSQL database (Mongo) for their product. However, their product is incredibly slow - which might be due to either the efficiency of their code, or/and the design of their database. While I wasn't hired as a dev or sysadmin, and am no expert in DB design, I find the latter super interesting and thought it'd be interesting to see how valid or invalid my opinions on their db design are.

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.
