Port 12302: Remote Administration Daemon (RAD) is a system service that offers secure, remote, programmatic access to Solaris system configuration and run-time state

Port 12302 is assigned by IANA to rads (Remote Administration Daemon (RAD) is a system service that offers secure, remote, programmatic access to Solaris system configuration and run-time state).

01 Security

Is port 12302 dangerous?

We have no specific security note for port 12302. Its risk depends on the program actually listening on it. General advice for network services services:

  • Answer only the networks that need the service (no open resolvers, relays or reflectors).
  • UDP services can be abused for DDoS amplification: rate-limit or block them at the edge.
  • Disable legacy test services that have no use in production.

03 Check it

Which program uses port 12302, and is it reachable?

Linux

sudo ss -ltnup 'sport = :12302'      # process listening on 12302
sudo lsof -nP -i :12302

macOS

sudo lsof -nP -i :12302

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 12302 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 12302
netstat -ano | findstr :12302

From another machine

nmap -p 12302 -sV <host>
nc -zv <host> 12302

Block it in the firewall

sudo ufw deny 12302/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 12302" -Direction Inbound -LocalPort 12302 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 12302 used for?

Port 12302 is assigned by IANA to rads (Remote Administration Daemon (RAD) is a system service that offers secure, remote, programmatic access to Solaris system configuration and run-time state).

Is port 12302 TCP or UDP?

Port 12302 is registered for TCP.

Is it safe to open port 12302?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Answer only the networks that need the service (no open resolvers, relays or reflectors).

How do I check if port 12302 is open?

On Linux run "ss -ltnup 'sport = :12302'", on macOS "lsof -nP -i :12302", and on Windows "netstat -ano | findstr :12302" to see the local process. From another machine, "nmap -p 12302 <host>" shows whether it is reachable.
