RN528 - how to determine RAM config
Found this post:
https://community.netgear.com/t5/New-ReadyNAS-Users-General/528x-ram-memory-upgrades/m-p/1410735
User runs "hwinfo" and "dmidecode" to determine his RN528 RAM config.
I've opened a linux shell using PuTTy with root login (as shown below), but "sudo" isn't recognized, nor is "dmidecode" nor "hwinfo". I'm guessing I need some kind of supervisor privilege to access these commands, how do I get there?
In my "meminfo" file (exported logs), seems to say I have 32GB but I don't recall installing this memory upgrade. RN528 comes with 4GB stock (so I thought).
Just want to confirm what RAM module(s) are in this thing without opening it, if possible.

You don't need sudo, since you are logging in as root.
You can install dmidecode if you like with
apt-get install dmidecodeMy RN526x has one DIMM module installed.

Thanks StephenB , appears I do in fact have 2 16GB modules in the NAS already. Part# 36ASF2G72PZ-2G1B1, which is a 16GB module. I guess senility is creeping in... can't find a purchase receipt anywhere for these modules.
SMBIOS 3.0 present.
