c-icap-server reports unexpected timeout

I have configured c-icap-server and squidclamav to provide a network based malware scanning service for my applications. However it only appears to work when I can sent the entirety of the content in the preview and explicitly set an EOF.

I am monitoring the traffic with:

IPv6 vs IPv4 available subnets - enough or too less
cn flag

I read a bit about IPv6 and found that usually you get assigned a /48 prefix address. Which gives you 16 bit for subnetting.

Reading further assuming that you use /64 subnets you would end up with 65535 possible subnets with a lot of IP-Addresses in each of these.

My question is, how you deal with scenarios where 65535 Subnets are not sufficient. I mean you have to consider, that even small subnets  ...

The following syntax includes 22:35 and 22:50.

On our network we are getting an error every time we attempt to add a printer or sometimes print to printers. The error states that new drivers are needed to installed to print however we are using Xerox global driver. On my computer for example, I can print to the printer I have always been connected to, however I can not connect to any other printer. So far we found that when we remove windows update ...

Samba passdb backend with LDAP
in flag

I'm trying to set up a Samba server (smbd version: 4.13.13-Debian) and I can't get it to work with LDAP as a backend.

Adding passdb backend = ldapsam:ldap://192.168.1.2 (where the LDAP Server is in this given IP address) makes smbd crash on restart.

The Journal message [when trying to restart smbd] is:

How can I install some software on 25+ windows home laptops?

I work for a school. The kids do have laptops. The laptops are not guaranteed to be turned on at the same time. The laptops might be in the school or at home with the kids.

Idea: The desired state can be configured on some website (might be SaaS or on premise installation). I install some agent once on each laptop and target it to the service.

At some point on this website I configure

Hyper-V & Windows Server 2022 is creating a new network on each boot
ca flag

I have two virtual machines on my host (Windows Server 2022 and Windows 10) each time I reboot WS2022 it auto detects a new network on start however Windows 10 doesn't. So far we're up to network 20, but this is somewhat frustrating as I'd like it to stay on the original network on start. This is done through the prompt for turning on "network discovery" upon login.

Doesn't appear that anything c ...

Using a DNS server with ZeroTier

I have setup my own Zerotier Controller using ztncui and it works great, but there is one piece of my setup that I cannot seem to get to work and that is having clients use the DNS I configure for the ZeroTier network. The DNS is configured as follows:

Additional MX server for newsletters

I installed a newsletter control panel (Mailtrain) on a dedicated VPS. When I send a newsletter using the domain that is associated to the server itself (let's call it mymailserver.com) I have no doubt: I configured SPF, DKIM and DMARC on the DNS; the MX points to the hostname of the server itself.

The doubts begin when I want to send a newsletter using a different "From:" header. I have control  ...

Now the panel in grafana 8.2 is picture 1 : enter image description here

Admin Login, User Login, Login Fail are the values calculated from ID 4648, ID 4625, ID 4624 respectively. enter image description here

I don't want to show the 3 Query: ID 4648, ID 4625, ID 4624 in panel . I only show Admin Login, User Login, Login Fail in panel.

What settings do I have to do on grafana to achieve my goal ?

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.
