For sysadmins seeking continuous learning, these podcasts deliver deep technical insights:

• RunAs Radio: Microsoft-focused enterprise IT discussions with expert guests. Example episode covers PowerShell automation for AD management.
• Packet Pushers: Networking deep dives with protocol analysis. Recent episode explained BGP troubleshooting using Wireshark filter examples:

# Sample Wireshark filter for BGP analysis
bgp.type == 2 || bgp.type == 3 || tcp.port == 179

Critical listening for hardening systems:

• Security Now! Weekly vulnerability breakdowns. Their Log4j episode included mitigation scripts:

#!/bin/bash
# Quick patch check for Log4j
find / -name "log4j-core-*.jar" -exec sh -c 'unzip -p {} META-INF/MANIFEST.MF | grep "Implementation-Version"' \;

Stay current with infrastructure evolution:

• VMware VMTN: vSphere automation examples using PowerCLI. One episode demonstrated VM snapshot automation:

Connect-VIServer -Server vcenter.example.com
Get-VM -Name "Prod*" | New-Snapshot -Name "PrePatch_$(Get-Date -Format yyyyMMdd)"

These help anticipate infrastructure shifts:

• FLOSS Weekly: Open-source tool evaluations with installation benchmarks.
• TechNet Edge: Azure/Microsoft 365 administration patterns including ARM template examples.

For packet-level understanding:

• Network Security Podcast: Packet analysis workshops showing tcpdump filters for intrusion detection:

# Capture suspicious DNS traffic
tcpdump -ni eth0 'udp port 53 and (udp[10] & 0x80 != 0)'

Pro tip: Subscribe to podcast RSS feeds in your automation dashboard using Python:

import feedparser
sysadmin_feeds = ['http://packetpushers.net/feed/',
                 'https://feeds.twit.tv/floss.xml']
for feed in sysadmin_feeds:
    d = feedparser.parse(feed)
    print(f"Latest {d.feed.title}: {d.entries[0].title}")

For system administrators and network engineers looking to stay ahead, podcasts offer a goldmine of technical insights. Here are the most valuable shows covering infrastructure automation, cloud security, and enterprise networking:

Security Now! (grc.com) remains the definitive resource for deep technical analysis of vulnerabilities. Recent episodes have covered:

// Example of discussed vulnerability
CVE-2023-32456: 
  Impact: Remote Code Execution in Windows RPC
  CVSS Score: 9.8
  Mitigation: Apply MS Patch KB5028244
  Workaround: Disable TCP port 135

PaulDotCom Security provides weekly penetration testing case studies, often featuring Python scripts like:

import nmap
scanner = nmap.PortScanner()
scanner.scan('192.168.1.0/24', arguments='-sS -p 22,80,443')
for host in scanner.all_hosts():
    if scanner[host].state() == "up":
        print(f"Live host: {host}")

The VMware VMTN Podcast delivers advanced vSphere automation techniques. A recent episode demonstrated PowerCLI for mass VM configuration:

Get-VM | Where-Object {$_.PowerState -eq "PoweredOn"} |
  ForEach-Object {
    Set-VM -VM $_ -MemoryGB 8 -Confirm:$false
    Write-Host "Configured $($_.Name)"
  }

Packet Pushers offers vendor-neutral discussions on SD-WAN, BGP best practices, and network automation. Their Ansible for Network Engineers series includes examples like:

---
- name: Configure VLANs on Cisco switches
  hosts: switches
  tasks:
    - name: Add VLANs
      cisco.ios.ios_vlans:
        config:
          - vlan_id: 100
            name: Servers
          - vlan_id: 200  
            name: VoIP
      register: result

RunAs Radio focuses on PowerShell automation for Active Directory. Their latest episode included this user provisioning script:

Import-Csv new_users.csv | ForEach-Object {
  New-ADUser -Name $_.Name 
              -SamAccountName $_.Username 
              -Department $_.Dept 
              -Enabled $true
  Add-ADGroupMember "Department_$($_.Dept)" $_.Username
}

Hak5 covers IoT security and hardware hacking, often featuring Raspberry Pi projects with code snippets like:

#!/bin/bash
while true; do
  tshark -i wlan0 -f "port 53" -T fields -e ip.src -e dns.qry.name
  sleep 5
done
