01 Security

Is port 6077 dangerous?

We have no specific security note for port 6077. 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 6077, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6077'      # process listening on 6077
sudo lsof -nP -i :6077

macOS

sudo lsof -nP -i :6077

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6077 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6077
netstat -ano | findstr :6077

From another machine

nmap -p 6077 -sV <host>
nc -zv <host> 6077

Block it in the firewall

sudo ufw deny 6077/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6077" -Direction Inbound -LocalPort 6077 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6077 used for?

Port 6077 is assigned by IANA to iconstructsrv (iConstruct Server).

Is port 6077 TCP or UDP?

Port 6077 is registered for TCP.

Is it safe to open port 6077?

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 6077 is open?

On Linux run "ss -ltnup 'sport = :6077'", on macOS "lsof -nP -i :6077", and on Windows "netstat -ano | findstr :6077" to see the local process. From another machine, "nmap -p 6077 <host>" shows whether it is reachable.
