01 Security

Is port 1461 dangerous?

We have no specific security note for port 1461. 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 1461, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1461'      # process listening on 1461
sudo lsof -nP -i :1461

macOS

sudo lsof -nP -i :1461

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1461 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1461
netstat -ano | findstr :1461

From another machine

nmap -p 1461 -sV <host>
sudo nmap -sU -p 1461 <host>
nc -zv <host> 1461

Block it in the firewall

sudo ufw deny 1461/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1461" -Direction Inbound -LocalPort 1461 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1461 used for?

Port 1461 is assigned by IANA to ibm_wrless_lan (IBM Wireless LAN), ibm-wrless-lan (IBM Wireless LAN IANA assigned this well-formed service name as a replacement for "ibm_wrless_lan".).

Is port 1461 TCP or UDP?

Port 1461 is registered for TCP and UDP.

Is it safe to open port 1461?

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 1461 is open?

On Linux run "ss -ltnup 'sport = :1461'", on macOS "lsof -nP -i :1461", and on Windows "netstat -ano | findstr :1461" to see the local process. From another machine, "nmap -p 1461 <host>" shows whether it is reachable.
