01 Security

Is port 3895 dangerous?

We have no specific security note for port 3895. 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 3895, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3895'      # process listening on 3895
sudo lsof -nP -i :3895

macOS

sudo lsof -nP -i :3895

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3895 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3895
netstat -ano | findstr :3895

From another machine

nmap -p 3895 -sV <host>
sudo nmap -sU -p 3895 <host>
nc -zv <host> 3895

Block it in the firewall

sudo ufw deny 3895/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3895" -Direction Inbound -LocalPort 3895 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3895 used for?

Port 3895 is assigned by IANA to syam-smc (SyAm SMC Service Port).

Is port 3895 TCP or UDP?

Port 3895 is registered for TCP and UDP.

Is it safe to open port 3895?

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 3895 is open?

On Linux run "ss -ltnup 'sport = :3895'", on macOS "lsof -nP -i :3895", and on Windows "netstat -ano | findstr :3895" to see the local process. From another machine, "nmap -p 3895 <host>" shows whether it is reachable.
