01 Security

Is port 29168 dangerous?

We have no specific security note for port 29168. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 29168, and is it reachable?

Linux

sudo ss -ltnup 'sport = :29168'      # process listening on 29168
sudo lsof -nP -i :29168

macOS

sudo lsof -nP -i :29168

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 29168 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 29168
netstat -ano | findstr :29168

From another machine

nmap -p 29168 -sV <host>
nc -zv <host> 29168

Block it in the firewall

sudo ufw deny 29168/sctp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 29168" -Direction Inbound -LocalPort 29168 -Protocol SCTP -Action Block  # Windows
04 FAQ
What is port 29168 used for?

Port 29168 is assigned by IANA to sbcap (SBcAP in 3GPP).

Is port 29168 TCP or UDP?

Port 29168 is registered for SCTP.

Is it safe to open port 29168?

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. Close the port if nothing on the host needs it.

How do I check if port 29168 is open?

On Linux run "ss -ltnup 'sport = :29168'", on macOS "lsof -nP -i :29168", and on Windows "netstat -ano | findstr :29168" to see the local process. From another machine, "nmap -p 29168 <host>" shows whether it is reachable.
