pulling model, serial number, netgate device ID from CLI

[brandilton]

When I initially SSH in, the very first line before it shows the menu is:

Netgate 3100 - Serial: XXXXXXXXXXX - Netgate Device ID: yyyyyyyyyyyyyyyyy

I can grab that and parse it, but I'm wondering if there's a better way to descretely grab those 3 pieces of information to store as variables for an asset inventory project I'm working on. We also have some non-netgate devices I'd like to be able to capture model/serial information on if possible.

On 23.05, you can get some info out of the nodes under sysctl dev.netgate for example dev.netgate.model

But if you look at the source of /etc/rc.banner which draws the top lines of the menu, you can find the functions which fetch the other info. Some of it comes from kenv.

@jimp super helpful - just what I needed! I'm a powershell guy and here's where I landed on this in case anyone else is in the same boat:

$hardwareModelRaw = & "$env:ProgramFiles\putty\plink.exe" admin@$pfSenseIP -pw $pfSensePW -batch -hostkey $pfSenseHostKey 'sysctl dev.netgate.desc'
$pos = $hardwareModelRaw.indexof(": ")
$hardwareModel = $hardwareModelRaw.substring($pos+2)
$pfSerialNumber = & "$env:ProgramFiles\putty\plink.exe" admin@$pfSenseIP -pw $pfSensePW -batch -hostkey $pfSenseHostKey  '/bin/kenv -q uboot.boardsn'
