01 Security

Is port 2077 dangerous?

We have no specific security note for port 2077. 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 2077, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2077'      # process listening on 2077
sudo lsof -nP -i :2077

macOS

sudo lsof -nP -i :2077

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2077 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2077
netstat -ano | findstr :2077

From another machine

nmap -p 2077 -sV <host>
sudo nmap -sU -p 2077 <host>
nc -zv <host> 2077

Block it in the firewall

sudo ufw deny 2077/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2077" -Direction Inbound -LocalPort 2077 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2077 used for?

Port 2077 is assigned by IANA to tsrmagt (Old Tivoli Storage Manager).

Is port 2077 TCP or UDP?

Port 2077 is registered for TCP and UDP.

Is it safe to open port 2077?

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 2077 is open?

On Linux run "ss -ltnup 'sport = :2077'", on macOS "lsof -nP -i :2077", and on Windows "netstat -ano | findstr :2077" to see the local process. From another machine, "nmap -p 2077 <host>" shows whether it is reachable.
