How snmpssh-trap works

The client opens a session to port 5162: each command typed is sent to the server, which runs it and returns the output.

01 Security

Is port 5162 dangerous?

We have no specific security note for port 5162. Its risk depends on the program actually listening on it. General advice for remote access services:

  • Do not expose remote administration directly: use a VPN or a zero-trust access proxy.
  • Require MFA or key-based authentication and lock out brute-force attempts.
  • Log every login and alert on new source addresses.

03 Check it

Which program uses port 5162, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5162'      # process listening on 5162
sudo lsof -nP -i :5162

macOS

sudo lsof -nP -i :5162

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5162 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5162
netstat -ano | findstr :5162

From another machine

nmap -p 5162 -sV <host>
nc -zv <host> 5162

Block it in the firewall

sudo ufw deny 5162/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5162" -Direction Inbound -LocalPort 5162 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5162 used for?

Port 5162 is assigned by IANA to snmpssh-trap (SNMP Notification over SSH Transport Model).

Is port 5162 TCP or UDP?

Port 5162 is registered for TCP.

Is it safe to open port 5162?

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. Do not expose remote administration directly: use a VPN or a zero-trust access proxy.

How do I check if port 5162 is open?

On Linux run "ss -ltnup 'sport = :5162'", on macOS "lsof -nP -i :5162", and on Windows "netstat -ano | findstr :5162" to see the local process. From another machine, "nmap -p 5162 <host>" shows whether it is reachable.
