Design Patterns & Refactoring

Posted by jpluimers on 2019/07/16

Design Patterns and Refactoring articles and guides. Design Patterns video tutorials for newbies. Simple descriptions and full source code examples in Java, C++, C#, PHP and Delphi.

Not sure why yet, but sometimes ping and nslookup cannot reverse lookup a machine by IPv4, but tracert can

Posted by jpluimers on 2019/07/15

A while ago I had a situation that when doing a ping or nslookup on an IPv4 address in Windows, it would not show the name through reverse lookup, but tracert could.

It is not quite the same as what happened in these posts:

This post is basically a place to put notes in when this ever happens again.

ESXi Embedded Host Client

Posted by jpluimers on 2019/07/15

This version of the ESXi Embedded Host Client is written purely in HTML and JavaScript, and is served directly from your ESXi host and should perform much better than any of the existing solutions.

Installing went smooth:

# esxcli software vib install -v https://download3.vmware.com/software/vmw-tools/esxui/esxui-signed-6360286.vib -f
Installation Result

Reminder to self: MacOS prints to HP printers using IPP on port 631

Posted by jpluimers on 2019/07/12

At a site, something in the network filtering changed, so printing from a Mac failed.

In the end this was about port 631, which is for the IPP protocol a Mac uses.

Government & Govt Owned – Netherlands – Phishing Scorecard

Posted by jpluimers on 2019/07/12

The archive is of late 2017; I wonder what the state is now: [WaybackGovernment & Govt Owned – Netherlands – Phishing Scorecard

This Phishing Scorecard is the current situation of the security of e-mail stream banks compared. If a bank is one of the technical building blocks to implement in their e-mail security the red cross will be a green check mark. Once a bank’s security policy has only green check marks will stand up and protect them 40% of their customers.

De mailservers van de Tweede Kamer missen beveiligingsmaatregelen die e-mailspoofing tegen moeten gaan, waardoor het mogelijk is om uit naam van politici e-mails te versturen. Dat blijkt uit een onderzoek van Follow the Money.
