01 Security

Is port 1160 dangerous?

We have no specific security note for port 1160. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

03 Check it

Which program uses port 1160, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1160'      # process listening on 1160
sudo lsof -nP -i :1160

macOS

sudo lsof -nP -i :1160

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1160 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1160
netstat -ano | findstr :1160

From another machine

nmap -p 1160 -sV <host>
sudo nmap -sU -p 1160 <host>
nc -zv <host> 1160

Block it in the firewall

sudo ufw deny 1160/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1160" -Direction Inbound -LocalPort 1160 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1160 used for?

Port 1160 is assigned by IANA to olsv (DB Lite Mult-User Server).

Is port 1160 TCP or UDP?

Port 1160 is registered for TCP and UDP.

Is it safe to open port 1160?

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. Bind the service to localhost or a private network, never to a public address.

How do I check if port 1160 is open?

On Linux run "ss -ltnup 'sport = :1160'", on macOS "lsof -nP -i :1160", and on Windows "netstat -ano | findstr :1160" to see the local process. From another machine, "nmap -p 1160 <host>" shows whether it is reachable.
