01 Security

Is port 185 dangerous?

We have no specific security note for port 185. 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 185, and is it reachable?

Linux

sudo ss -ltnup 'sport = :185'      # process listening on 185
sudo lsof -nP -i :185

macOS

sudo lsof -nP -i :185

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 185 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 185
netstat -ano | findstr :185

From another machine

nmap -p 185 -sV <host>
sudo nmap -sU -p 185 <host>
nc -zv <host> 185

Block it in the firewall

sudo ufw deny 185/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 185" -Direction Inbound -LocalPort 185 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 185 used for?

Port 185 is assigned by IANA to remote-kis (Remote-KIS).

Is port 185 TCP or UDP?

Port 185 is registered for TCP and UDP.

Is it safe to open port 185?

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 185 is open?

On Linux run "ss -ltnup 'sport = :185'", on macOS "lsof -nP -i :185", and on Windows "netstat -ano | findstr :185" to see the local process. From another machine, "nmap -p 185 <host>" shows whether it is reachable.
