Is port 8055 dangerous?

We have no specific security note for port 8055. 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 8055, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8055'      # process listening on 8055
sudo lsof -nP -i :8055

macOS

sudo lsof -nP -i :8055

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8055 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8055
netstat -ano | findstr :8055

From another machine

nmap -p 8055 -sV <host>
sudo nmap -sU -p 8055 <host>
nc -zv <host> 8055

Block it in the firewall

sudo ufw deny 8055/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8055" -Direction Inbound -LocalPort 8055 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8055 used for?

Port 8055 is assigned by IANA to senomix04 (Senomix Timesheets Server [1 year assignment]).

Is port 8055 TCP or UDP?

Port 8055 is registered for TCP and UDP.

Is it safe to open port 8055?

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 8055 is open?

On Linux run "ss -ltnup 'sport = :8055'", on macOS "lsof -nP -i :8055", and on Windows "netstat -ano | findstr :8055" to see the local process. From another machine, "nmap -p 8055 <host>" shows whether it is reachable.
