01 Security

Is port 1010 dangerous?

We have no specific security note for port 1010. 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 1010, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1010'      # process listening on 1010
sudo lsof -nP -i :1010

macOS

sudo lsof -nP -i :1010

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1010 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1010
netstat -ano | findstr :1010

From another machine

nmap -p 1010 -sV <host>
sudo nmap -sU -p 1010 <host>
nc -zv <host> 1010

Block it in the firewall

sudo ufw deny 1010/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1010" -Direction Inbound -LocalPort 1010 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1010 used for?

Port 1010 is assigned by IANA to surf (surf).

Is port 1010 TCP or UDP?

Port 1010 is registered for TCP and UDP.

Is it safe to open port 1010?

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 1010 is open?

On Linux run "ss -ltnup 'sport = :1010'", on macOS "lsof -nP -i :1010", and on Windows "netstat -ano | findstr :1010" to see the local process. From another machine, "nmap -p 1010 <host>" shows whether it is reachable.
