Admin Admin Podcast #025 Show Notes – Config management & code control



Linux Config management & code control


  • Needs an agent installed
    • Uses SSL self-signed certs
    • “Declarative state”


    • No agent needed
    • Uses SSH
    • Procedural (stepwise)

Version control in this context

  • git
    • branching – develop code in a branch
    • hooks – automatically do things when certain events happen
    • Omnibus package


The dates have been realised and we will be there. It being held in Liverpool, Oct 30th – Nov 1st 2015!

  – 3com 3c905c NIC
  – Maldet for malware detection on Linux machines – geared towards web servers, Plesk/cPanel etc.
  – mailwrapper – write mails sent by PHP scripts to a log – Plesk-specific, but may work on other platforms
  – s3cmd for copying/moving/syncing operations from a Linux machine to Amazon S3.
    – To get the the ‘s3cmd –configure’ to work, you have to put in a policy document (basically to allow the list operation.
  – Because of Amazon’s pricing structure, it’s more cost-effective to backup to S3, then archive that to Glacier after a while. See this howto

  – UNIX sockets – as usual, Wikipedia has a more concise, insightful explanation than Jerry!
  – Log files are your friend! – /var/log/*.log
Misc, and recommendations:

Admin Admin Podcast #022 Show Notes – The Bee’s Knees

This week, Jerry is back from the dead, we discuss Andy’s upcoming mega site visit and talk AD & Lync.

Jerry back from the dead

Andy’s audacious intervention



The plan:

  • Sort the network out
  • Set up users on the new NAS box
  • Set up different share on the NAS box for different purposes (effectively different partitions)

RAID levels

  • RAID0 – striping across drives
  • RAID1 – Mirror across drives
  • RAID5 – Distributed parity
  • JBOD – Just a Bunch of Disks
  • RAID10/RAID50 – Striping and Mirroring

RAID is not backup

What happens when you RAID 24 SSD drives?


  • Offsite – in case the office burns down
  • Synology Sync
  • Crashplan

Careful with that ACT database, Andy!
