01 Security

Is port 1454 dangerous?

We have no specific security note for port 1454. 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 1454, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1454'      # process listening on 1454
sudo lsof -nP -i :1454

macOS

sudo lsof -nP -i :1454

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1454 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1454
netstat -ano | findstr :1454

From another machine

nmap -p 1454 -sV <host>
sudo nmap -sU -p 1454 <host>
nc -zv <host> 1454

Block it in the firewall

sudo ufw deny 1454/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1454" -Direction Inbound -LocalPort 1454 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1454 used for?

Port 1454 is assigned by IANA to interhdl_elmd (interHDL License Manager), interhdl-elmd (interHDL License Manager IANA assigned this well-formed service name as a replacement for "interhdl_elmd".).

Is port 1454 TCP or UDP?

Port 1454 is registered for TCP and UDP.

Is it safe to open port 1454?

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 1454 is open?

On Linux run "ss -ltnup 'sport = :1454'", on macOS "lsof -nP -i :1454", and on Windows "netstat -ano | findstr :1454" to see the local process. From another machine, "nmap -p 1454 <host>" shows whether it is reachable.
