- 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.

Which program uses port 94, and is it reachable?
Linux
sudo ss -ltnup 'sport = :94' # process listening on 94
sudo lsof -nP -i :94macOS
sudo lsof -nP -i :94
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 94 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 94 netstat -ano | findstr :94
From another machine
nmap -p 94 -sV <host> sudo nmap -sU -p 94 <host> nc -zv <host> 94
Block it in the firewall

What is port 94 used for?
Port 94 is assigned by IANA to objcall (Tivoli Object Dispatcher).
Is port 94 TCP or UDP?
Port 94 is registered for TCP and UDP.
Is it safe to open port 94?
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 94 is open?
On Linux run "ss -ltnup 'sport = :94'", on macOS "lsof -nP -i :94", and on Windows "netstat -ano | findstr :94" to see the local process. From another machine, "nmap -p 94 <host>" shows whether it is reachable.
