Which program uses port 2735, and is it reachable?
Linux
sudo ss -ltnup 'sport = :2735' # process listening on 2735
sudo lsof -nP -i :2735macOS
sudo lsof -nP -i :2735
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 2735 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 2735 netstat -ano | findstr :2735
From another machine
nmap -p 2735 -sV <host> sudo nmap -sU -p 2735 <host> nc -zv <host> 2735
Block it in the firewall

What is port 2735 used for?
Port 2735 is assigned by IANA to netiq-mc (NetIQ Monitor Console).
Is port 2735 TCP or UDP?
Port 2735 is registered for TCP and UDP.
Is it safe to open port 2735?
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. Restrict management and monitoring protocols to the monitoring network.
How do I check if port 2735 is open?
On Linux run "ss -ltnup 'sport = :2735'", on macOS "lsof -nP -i :2735", and on Windows "netstat -ano | findstr :2735" to see the local process. From another machine, "nmap -p 2735 <host>" shows whether it is reachable.
