01 Security

Is port 5048 dangerous?

We have no specific security note for port 5048. 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 5048, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5048'      # process listening on 5048
sudo lsof -nP -i :5048

macOS

sudo lsof -nP -i :5048

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5048 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5048
netstat -ano | findstr :5048

From another machine

nmap -p 5048 -sV <host>
nc -zv <host> 5048

Block it in the firewall

sudo ufw deny 5048/tcp                                         # Linux (ufw)

04 FAQ
What is port 5048 used for?

Port 5048 is assigned by IANA to texai (Texai Message Service).

Is port 5048 TCP or UDP?

Port 5048 is registered for TCP.

Is it safe to open port 5048?

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 5048 is open?

On Linux run "ss -ltnup 'sport = :5048'", on macOS "lsof -nP -i :5048", and on Windows "netstat -ano | findstr :5048" to see the local process. From another machine, "nmap -p 5048 <host>" shows whether it is reachable.
