01 Security

Is port 26486 dangerous?

We have no specific security note for port 26486. 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 26486, and is it reachable?

Linux

sudo ss -ltnup 'sport = :26486'      # process listening on 26486
sudo lsof -nP -i :26486

macOS

sudo lsof -nP -i :26486

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 26486 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 26486
netstat -ano | findstr :26486

From another machine

nmap -p 26486 -sV <host>
sudo nmap -sU -p 26486 <host>
nc -zv <host> 26486

Block it in the firewall

sudo ufw deny 26486/tcp                                         # Linux (ufw)

04 FAQ
What is port 26486 used for?

Port 26486 is assigned by IANA to exoline-tcp (EXOline-TCP), exoline-udp (EXOline-UDP).

Is port 26486 TCP or UDP?

Port 26486 is registered for TCP and UDP.

Is it safe to open port 26486?

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 26486 is open?

On Linux run "ss -ltnup 'sport = :26486'", on macOS "lsof -nP -i :26486", and on Windows "netstat -ano | findstr :26486" to see the local process. From another machine, "nmap -p 26486 <host>" shows whether it is reachable.
