I want my OpenBSD 6.4 services to authenticate users from a remote LDAP server ; namely a Synology Directory Server (DSM 6.2.x). It turns out that this a standard OpenLDAP 2.4.x configured to accept replication refreshAndPersist mode. So let’s configure a Master / Slave Replication system between Synology and OpenBSD.
Synology DSM can be configured to send notifications on various events. It can use Email, SMS and Push Service. I usually use email notifications to check for status. But here’s how I configured SMS notification for critical events using the French mobile operator “Free Mobile”.
Step 1 was getting my hands on Raspbian. Step 2 was running OpenBSD on the Raspberry Pi 3 Model B. I had quite a few try & fails but it booted, installed and ran properly in the end. Full story follows.
Raspberry Pi can be used with a prepared OS, booted up and just used. But when it comes to customising or doing something else than what was planned, you may need to use the console. And that requires a TTL adapter connected to the GPIO. The thing is, using MacOS is not as straightforward as I thought. So here are my notes.
On the official Synology website, the DiskStation DS918+ has “Memory Expandable up to 8 GB (4 GB x 2)”. Well, in reality, it supports a bit more than this…
