Windows Docker slow socket connect
cn flag

I have two docker containers which are trying to talk to another using web requests, but are experiencing random latency. While debugging, I've broken the issue down to slow socket connection times, by running a simple socketserver in one

import socket
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serversocket.bind(('0.0.0.0', 80))
serversocket.listen(5)

Uniform Server cron not executing php script
cn flag

I'm running Uniform Server Zero XIV and am trying to use the cron to run a php script every 15 minutes. When ran manually, the script does what it is supposed to, which is updating values in a database. However, the cron never seems to actually execute the script.

The cron log is indicating that the crontab has the correct path and is executing.

iptables keep tracks of source IP address

We have a Strongswan VPN server on Ubuntu 20.04 in AWS. It is used to establish a site-to-site VPN tunnel with a client.

Here's a simple topology diagram: enter image description here

Our VPN server will terminate VPN and NAT traffic to the RDS database server. In order for it to response correctly our VPN server will SNAT the packet with its address, so we basically lost track of the client computer's IP address. And there are mult ...

Is there a solution that does with Phusion Passenger does, but for multiple Docker websites?
cn flag

Let's assume I have a server running multiple Dockerized websites - I realise that I can configure a reverse proxy (such as Nginx or Apache) to examine the headers of incoming HTTP requests, and send them through to different local ports, if I run each Dockerized website on a different local port number - thereby hosting several [smaller] websites on one host.

However, the configuration of this a ...

RHEL 7.9: rpm --eval "%dist" is now .el7_9 instead of just .el7
lr flag

Here, we've recently upgraded some of our systems from RHEL 7.8 to RHEL 7.9, and I'm facing an issue related to the "dist" returned by the rpm tool.

In some scripts, we share between RHEL7 and RHEL8 systems, we use the command: rpm --eval "%dist" to determine the local RHEL flavor: ".el7" or ".el8"

Starting with RHEL 7.9, the command now return: ".el7_9" instead of just ".el7".

Why is Microsoft Windows Update (KB5003220) breaking authentication to my File Share
cn flag

We have a file share on our SAN using CIFS/SMB protocol. Immediately upon applying this particular Windows Update (KB5003220), authentication to the file share breaks. Does anyone know what causes this?

Further testing has shown that the file share is still accessible using host name after the update, but not using the IP address - which is how most of our users had the network drive mapped. Why  ...

In our environment, only one of our AIX servers is permitted to access the internet through the firewall. On this one server, I use suma to download all fixes for all base levels, technology levels and service packs that we have in our environment; this is done daily.

Is there a way in DOS to list only the files in specific subdirectories and not include the root directory?
gr flag

I have a series of folders (parent directories) on a network drive. Each of the parent directories contain multiple subdirectories. One of the subdirectories is common to all parent directories. This subdirectory is called "InProcess". I want to list all files that only reside in the "InProcess" subdirectories of the parents.

Can this be done with a batch file?

Bridge not forwarding the neighbor advertisement
it flag

I have a bridge created using libvirt and two VMs. I can ping both VMs using ipv4. However, when pinging using ipv6 addresses, it does not work. I can see the neighbor solicitation leaving VM1 and reaching VM2. Then, I can see VM2 replying with a neighbor advertisement. However, the bridge "eats" that packet because I no longer see it in the VM1 link.

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.
