01 Security

Is port 2577 dangerous?

We have no specific security note for port 2577. 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 2577, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2577'      # process listening on 2577
sudo lsof -nP -i :2577

macOS

sudo lsof -nP -i :2577

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2577 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2577
netstat -ano | findstr :2577

From another machine

nmap -p 2577 -sV <host>
sudo nmap -sU -p 2577 <host>
nc -zv <host> 2577

Block it in the firewall

sudo ufw deny 2577/tcp                                         # Linux (ufw)

What is port 2577 used for?

Port 2577 is assigned by IANA to scipticslsrvr (Scriptics Lsrvr).

Is port 2577 TCP or UDP?

Port 2577 is registered for TCP and UDP.

Is it safe to open port 2577?

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 2577 is open?

On Linux run "ss -ltnup 'sport = :2577'", on macOS "lsof -nP -i :2577", and on Windows "netstat -ano | findstr :2577" to see the local process. From another machine, "nmap -p 2577 <host>" shows whether it is reachable.
