01 Security

Is port 38462 dangerous?

We have no specific security note for port 38462. 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 38462, and is it reachable?

Linux

sudo ss -ltnup 'sport = :38462'      # process listening on 38462
sudo lsof -nP -i :38462

macOS

sudo lsof -nP -i :38462

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 38462 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 38462
netstat -ano | findstr :38462

From another machine

nmap -p 38462 -sV <host>
nc -zv <host> 38462

Block it in the firewall

sudo ufw deny 38462/sctp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 38462" -Direction Inbound -LocalPort 38462 -Protocol SCTP -Action Block  # Windows
04 FAQ
What is port 38462 used for?

Port 38462 is assigned by IANA to e1-interface (E1 signalling transport (3GPP)).

Is port 38462 TCP or UDP?

Port 38462 is registered for SCTP.

Is it safe to open port 38462?

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 38462 is open?

On Linux run "ss -ltnup 'sport = :38462'", on macOS "lsof -nP -i :38462", and on Windows "netstat -ano | findstr :38462" to see the local process. From another machine, "nmap -p 38462 <host>" shows whether it is reachable.
