01 Security

Is port 8183 dangerous?

We have no specific security note for port 8183. 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 8183, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8183'      # process listening on 8183
sudo lsof -nP -i :8183

macOS

sudo lsof -nP -i :8183

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8183 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8183
netstat -ano | findstr :8183

From another machine

nmap -p 8183 -sV <host>
nc -zv <host> 8183

Block it in the firewall

sudo ufw deny 8183/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8183" -Direction Inbound -LocalPort 8183 -Protocol TCP -Action Block  # Windows

What is port 8183 used for?

Port 8183 is assigned by IANA to proremote (ProRemote).

Is port 8183 TCP or UDP?

Port 8183 is registered for TCP.

Is it safe to open port 8183?

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 8183 is open?

On Linux run "ss -ltnup 'sport = :8183'", on macOS "lsof -nP -i :8183", and on Windows "netstat -ano | findstr :8183" to see the local process. From another machine, "nmap -p 8183 <host>" shows whether it is reachable.
