3 + .SYNOPSIS
4 + Universal DHCP Scope Monitoring Utility
5 +
6 + .DESCRIPTION
7 + Cross-platform DHCP monitoring utility for:
8 + - Windows
9 + - macOS
10 + - Linux (including Debian)
11 +
12 + Execution modes:
13 + 1. LOCAL : On Windows with the DhcpServer module available.
14 + 2. REMOTE : On Windows/macOS/Linux using PowerShell Remoting over SSH
15 + to a Windows DHCP Server.
16 +
17 + Remote DHCP objects are flattened on the Windows server before being
18 + returned to non-Windows clients, avoiding CIM/MI serialization issues
19 + such as libmi errors on macOS/Linux.
20 +
21 + .EXAMPLE
22 + pwsh ./dhcp-monitor-universal.ps1
23 +
24 + On macOS/Linux (or Windows without the local DhcpServer module), the
25 + script asks for the DHCP Server hostname/IP and SSH username.
26 +
27 + .EXAMPLE
28 + pwsh ./dhcp-monitor-universal.ps1 -DhcpServer 192.168.1.10 -UserName "CONTOSO\\administrator"
29 +
30 + Skips the interactive server/username questions.
31 +
32 + .EXAMPLE
33 + pwsh ./dhcp-monitor-universal.ps1 -Mode Local
34 +
35 + Forces Local mode. Requires Windows and the DhcpServer module.
36 +
37 + .NOTES
38 + In Remote mode, the script interactively asks for:
39 + - DHCP Server hostname or IP address
40 + - SSH username
