01 Security

Is port 180 dangerous?

We have no specific security note for port 180. 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 180, and is it reachable?

Linux

sudo ss -ltnup 'sport = :180'      # process listening on 180
sudo lsof -nP -i :180

macOS

sudo lsof -nP -i :180

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 180 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 180
netstat -ano | findstr :180

From another machine

nmap -p 180 -sV <host>
sudo nmap -sU -p 180 <host>
nc -zv <host> 180

Block it in the firewall

sudo ufw deny 180/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 180" -Direction Inbound -LocalPort 180 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 180 used for?

Port 180 is assigned by IANA to ris (Intergraph).

Is port 180 TCP or UDP?

Port 180 is registered for TCP and UDP.

Is it safe to open port 180?

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 180 is open?

On Linux run "ss -ltnup 'sport = :180'", on macOS "lsof -nP -i :180", and on Windows "netstat -ano | findstr :180" to see the local process. From another machine, "nmap -p 180 <host>" shows whether it is reachable.
