How to stop inventory reset on logout from dedicated server?

So, for a while I thought I was dying because of lack of life support wherever I logged out. I've had successful logouts/logins in beds in NPC stations, but now that's not even working.

Whenever I logout, even for just a few minutes, the server seems to just delete my character. When I log back in, it spawns me at the Survival Kit, with a new set of base-level tools, full O2, and full H2. I'd like to log back in to where I log out, and cryochambers are out of reach due to lack of silver for medical components.

How do I stop losing my inventory on logout, and stop being teleported back to my survival kit on login?

EDIT: Okay, so Cryo Pods and beds will work. The problem I had with the bed was that the NPC station I was using has two bedrooms - one downstairs with two beds, and one upstairs with three. The upstairs bedroom, however, while airtight... has no vent. So I assume what happened is I used up all of the oxygen and died. The downstairs two-bed has access to the station's O2 system, and I've survived two nights in a row there, now.

So now this question is simply about changing the server settings (or installing a mod) so that players who logout (or crash to desktop) have their inventories preserved (at least as long as they aren't proactively hunted down and killed by weapons fire).
