Linux Action News - Just as the title says
Linux Unplugged - More current events and tech
User Error - “Off Topic” show by the same guys that do the above shows
Linux Destination - Linux news and tech
Late Night Linux - News by people in the industry, these guys work on Solus and Ubuntu Mate
I listen to these two shows off and on. Microsoft focus with a huge devotion to DevOps. Lot of great guests.
Sysadmin Today - Microsoft and VMware focused, but great content. Goes over stories and best practices.
Iron Sysadmin - Linux focused. News and a “tutorial” at the end. Great start imo. This and Sysadmin Today are newer.
Podcasts done by the same group, they care about open source passionately. The first is general news, the other two focused on their language.
.NET focused, but the topics they cover apply to a wide range of languages. My personal favorite.
Defensive Security Podcast
Southern Fried Security
Brakeing Down Security (yes, that’s spelled correctly)
Paul’s Security Weekly
I don’t listen to these anymore, because I’m not in that field anymore. Highly recommend them, though!
