We generally connect to backend servers via a jump-box or bastion host. On Windows this means RDP into the jump-box, then RDP from the jump-box to the backend server. However, recently a Windows update meant that the jump-box (which had the update) couldn’t RDP to the backend server (which hadn’t got the update). No RDP => no access to update the VM to restore RDP. Lots of fun!
In that case I managed to use Remmina from a Linux box to access the backend directly; however since we are going to hit this issue again we needed a better fix.
Cue PowerShell; this is deployed via Octopus so will work when RDP doesn’t. As an additional perk it means updating becomes much easier. Continue reading →
Just finished some radiator cover brackets: One of the really great things about having a workshop is being able to make exactly the right bracket to solve a simple problem. Saves all that wandering round a DIY shop looking for … Continue reading →
You need to keep the time consistent across your machines for a number of reasons – not the least is basic sanity. AD needs the time consistent as otherwise Kerberos won’t work. Standard practice is to use the DC as the time source. Fortunately NTP makes it pretty easy. Continue reading →
SaltStack provides an easy, fast way to manage systems – from one to thousands. One of its key capabilities is configuration management – “make it look like this” – and this series of posts describes how to implement the AD join described in a previous post. Continue reading →
Sometimes it is handy if users are managed somewhere other than /etc/passwd – somewhere central. Sometimes this happens to be Active Directory.
This post describes an approach on Debian Jessie against AD on Windows 2016 based on this excellent RedHat Guide’s Configuration 3 – SSSD/Kerberos/LDAP. It works very well for me. If you use a Debian-based distribution (Ubuntu, Debian etc) then hopefully it will work for you too.
I originally published this data on the Debian Wiki; I intend to expand it somewhat here.
