01 Security

Is port 1163 dangerous?

We have no specific security note for port 1163. 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 1163, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1163'      # process listening on 1163
sudo lsof -nP -i :1163

macOS

sudo lsof -nP -i :1163

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1163 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1163
netstat -ano | findstr :1163

From another machine

nmap -p 1163 -sV <host>
sudo nmap -sU -p 1163 <host>
nc -zv <host> 1163

Block it in the firewall

sudo ufw deny 1163/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1163" -Direction Inbound -LocalPort 1163 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1163 used for?

Port 1163 is assigned by IANA to sddp (SmartDialer Data Protocol).

Is port 1163 TCP or UDP?

Port 1163 is registered for TCP and UDP.

Is it safe to open port 1163?

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 1163 is open?

On Linux run "ss -ltnup 'sport = :1163'", on macOS "lsof -nP -i :1163", and on Windows "netstat -ano | findstr :1163" to see the local process. From another machine, "nmap -p 1163 <host>" shows whether it is reachable.
