ANSWER

Answered 2021-Jun-07 at 14:27

The Get-DhcpServerv4Scope cmdlet (all cmdlets that come with the DhcpServer module) is implemented as an (advanced) function^[1] (PowerShell code) rather than via a binary (as a class from a compiled .NET assembly, originally typically written in C#).
- To verify, inspect the output from
  (Get-Command Get-DhcpServerv4Scope).CommandType
Regrettably, these two implementation methods result in different behavior, and you're seeing one aspect of it:
- A (cmdlet-like advanced) function defined in a module does not see the caller's variables, which includes preference variables such as $ErrorActionPreference (except when calling directly from the global scope).
  - Therefore, such preference variables aren't honored. See GitHub issue #4568 for a discussion of this problematic behavior.
  - By contrast, common parameters such as -ErrorAction are processed correctly.
- Additional behavioral differences exist, independently of whether a given advanced function is defined in a module or not - see this answer.

Workaround:

Complement $ErrorActionPreference = 'Stop' with a local copy of $PSDefaultParameterValues that presets use of -ErrorAction Stop when calling cmdlets (from the caller's scope and its descendant scopes):

You forgot to put the type of the variable. If should be NsdManager.DiscoveryListener discoveryListener = new NsdManager.DiscoveryListener() {

You're also going to have the same problem with nsdManager. And in your last function because you use discoveryListener without defining it. When you copy pasted this code from somewhere did you forget to copy paste the instance variables of the class?

Unable to run multiple dnsmasq dhcp servers on ubuntu 18.04

Asked 2021-May-25 at 12:20

I've created a new network namespace for USB-ethernet and Wireless interface.

I run a DNSMASQ dhcp server on an interface with
sudo dnsmasq --port 5353 --interface wlp2s0 -F 123.12.1.101,123.12.1.200,24h
Which works like a charm.

I then want to set up another DNSMASQ dhcp server on the other interface with:
sudo dnsmasq --port 5454 --interface enx65ad574sa -F 123.12.1.101,123.12.1.200,24h
But this just reports dnsmasq: failed to bind DHCP server socket: Address already in use.

I am able to setup multiple dnsmasq dhcp servers if i run the dnsmasq outside the namespace, but inside a namespace, i can only have it running once.

If i create a configuration file:

ANSWER

Answered 2021-May-25 at 12:20

I ended up creating 2 separate dnsmasq configuration files, both has dhcp serve setup on the same interface, and then run the configarions concurrently in each their own network namespace - That means when the wireless interface is added to the network namespace, dnsmasq is already serving as dhcp server on the interface.

Apparently, setting up and starting 2 dnsmasq, that has their own configuration but with the same interface in both, does not interfere or break each other, and works quite seamlessly (atleast when they are started in separate network namespaces).

ANSWER

Answered 2021-May-19 at 17:04

There are a lot of different ways to manage transactions. Given your code, the simplest way would be to:

in a try block:

Create your connection in the caller that wraps both calls
Execute connection.setAutoCommit(false)
Call each of the methods findCar() and insertOrder()
Call connection.commit();

in the catch block:

call connection.rollback()

The connection is not created outside those functions, so don't forget to remove the connection setup from each function.

Installing wordpress to VM locally /etc/wordpress/config-localhost.php file

Asked 2021-May-05 at 23:56

so I am installing wordpress locally following https://ubuntu.com/tutorials/install-and-configure-wordpress in KVM/Qemu, when I get to stage 5 "configuring wordpress from the browser" where you set the site title username and password I get an error...

cannot find /etc/wordpress/config-192.168.122.54.php

But I know the file is actually named...

/etc/wordpress/config-localhost.php

So I copy the file config-localhost.php to config-192.168.122.54.php in the same directory and it takes me to page I expected to land on, to configure wordpress.

My question is should I proceed knowing the IP will change due to DHCP or is there a simpler solution. My VM network Interface is "Virtual Network 'default': NAT" if this matters?

I know this is a hack and probably will break but does anyone know the correct solution, why is it expecting me to connect from 'localhost' URI and not allowing me to connect remotely to the VM. Why is it taking the address from the URL to search for the file on the server??

According to DhcpEnumSubnets function, EnumInfo is a pointer to a DHCP_IP_ARRAY structure and it is valid to access the pointer like an array.
Yes, this assigns all needed values to the sruct and whether a pointer only holds one value in the index 0 or not depends on DhcpEnumSubnets function.
