Allow external clients to connect to minikube service

Allow external clients to connect to minikube service

Say you have a minikube cluster, you can use this minikube start tutorial as a reference, how can external applications or clients connect to it? You can run the following to expose balanced service (for example):

$: kubectl port-forward --address 0.0.0.0 service/balanced 8080:8080

Enable Copy/Paste using VMware Remote Console

Enable Copy/Paste using VMware Remote Console

VMware ESXi 6.5 disables copy/paste functionality by default for security reasons. If the security implications are acceptable, copy/paste funcationality can be enabled on per VM basis. It should be possible to change it at the host level but that will be for another post.

Follow the following steps to allow copy/paste:

• Power down the VM
• Do Actions | Edit Settings
  
  
• In Edit Settings window, look for Edit Configuration button
  
  
• Add the following parameters
  

  Key	Value
  isolation.tools.copy.disable	FALSE
  isolation.tools.paste.disable	FALSE
  isolation.tools.setGUIOptions.enable	TRUE

  
  
  
• Power up the VM

Visual Studio 2022 not running unit tests

Visual Studio 2022 not running unit tests

I have projects with unit tests working properly using Visual Studio 2019. Installed Visual Studio 2022 on another machine to try it out, running Nunit unit tests does nothing. It does not say it failed nor indicate something is wrong.

It was actuallying failing but I am not looking at the correct output log. As you observe from the above screen capture, the default log shows Build output. What you wanted is the log for Tests. See below for the correct view.

The Tests output shows the issue front and center. The tests were failing because it was configured to use .Net Core 3.1.x but it was not avaiable on the machine. One way to fix it is to use Visual Studio Installer and select .NET Core 3.1 Runtime (LTS).

Get hostname from an IP in Windows

Get hostname from an IP in Windows

Method 1 - Using built-in ping. This only works if a working DNS server has reverse look-up configured.

c:\>ping -a 8.8.8.8

The hostname for 8.8.8.8 was returned as dns.google, below shows the output details.

Pinging dns.google [8.8.8.8] with 32 bytes of data:
Reply from 8.8.8.8: bytes=32 time=52ms TTL=112
Reply from 8.8.8.8: bytes=32 time=56ms TTL=112
Reply from 8.8.8.8: bytes=32 time=59ms TTL=112
Reply from 8.8.8.8: bytes=32 time=56ms TTL=112

Ping statistics for 8.8.8.8:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 52ms, Maximum = 59ms, Average = 55ms

Method 2 - Using nslookup

c:\>nslookup 8.8.8.8

This is the same as method 1, it needs a working DNS to provide the information

Server:  somedc.com
Address:  some_ip_here

Name:    dns.google
Address:  8.8.8.8

Method 3 - Using nbtstat

c:\>nbtstat -a 192.168.1.101

With the added bonus that it also shows the MAC address and name M1. Limitiation is that this only works on network that supports NetBIOS and on the same collision domain.

vEthernet (nat):
Node IpAddress: [172.20.64.1] Scope Id: []

    Host not found.

Ethernet:
Node IpAddress: [192.168.1.100] Scope Id: []

           NetBIOS Remote Machine Name Table

       Name               Type         Status
    ---------------------------------------------
    WORKGROUP     	<00>  GROUP       Registered
    M1			  	<00>  UNIQUE      Registered
    M1     		  	<20>  UNIQUE      Registered

    MAC Address = 00-15-5D-0E-53-54

Method 4 - Using psexec

c:\>psexec \\192.168.1.101 -u administrator -p p@$$w0rd hostname

This is using psexec to run hostname command remotely. Note that it shows the hostname (M1), IP, and exit code of the command hostname.
