Port 24922 FIND
Port 24922 is the IANA-assigned find port for Find Identification of Network Devices (TCP / UDP).
What is port 24922 used for?
Port 24922 is assigned to find and uses TCP / UDP. The IANA registry describes the service as “Find Identification of Network Devices”. It sits above the registered range, where most numbers are transient client ports. A fixed high port is worth documenting precisely because tooling often assumes the default.
Ports are the transport-layer address a service listens on. A client that wants to reach find connects to port 24922. A TCP connection is refused when nothing is listening, while a UDP request simply goes unanswered. That is why a port conflict appears whenever two processes try to bind the same number.
Use the commands below to confirm whether port 24922 is actually in use before you change firewall rules. Blocking the port stops new inbound traffic at the firewall, but it does not stop a local process from listening, and it does not remove the service from the machine.

Check and block port 24922
Copy-ready commands for the protocols assigned to this port. Run the check first, then block only what should not be reachable.
Check on Linux
sudo ss -tlpn 'sport = :24922'
sudo ss -ulpn 'sport = :24922'Check on Windows
Get-NetTCPConnection -LocalPort 24922 -State Listen -ErrorAction SilentlyContinue
Get-NetUDPEndpoint -LocalPort 24922 -ErrorAction SilentlyContinueBlock with UFW
sudo ufw deny 24922/tcp
sudo ufw deny 24922/udpBlock with iptables
sudo iptables -A INPUT -p tcp --dport 24922 -j DROP
sudo iptables -A INPUT -p udp --dport 24922 -j DROPThese commands are examples for a typical host. Check the listener before you change firewall rules, and persist iptables rules with iptables-save or netfilter-persistent. On Windows, use Windows Defender Firewall or New-NetFirewallRule for persistent blocks. The iptables rules here cover IPv4; mirror them with ip6tables if IPv6 is enabled.
Is port 24922 safe to expose?
This port is not on our curated list of services with a widely exploited profile. Exposure is only safe when the listening service is intended, patched and protected by a firewall. Keep the listening service patched and remove it if unused. A default-deny firewall policy with explicit allow rules is still the safest baseline.
Where port 24922 is usually used
Most traffic on port 24922 falls into these scenarios. The demo below is a safe way to confirm the listener before you change anything.
- Custom or vendor-specific services configured to use a fixed high number.
- Short-lived container or test environments that publish the port on the host.
- Firewall planning, since most other high ports are transient client ports.
Probe the port
Confirm something is listening before you debug the client. This checks a TCP handshake on the port.
nc -vz 127.0.0.1 24922Common problems with port 24922
Connection refused or timed out
Refused usually means the host is reachable but nothing is listening on port 24922. A timeout more often means a firewall drop, a wrong host or a service bound to a different interface.
Port already in use
Find the process holding the port with sudo ss -tlpn 'sport = :24922' or sudo lsof -i :24922. Stop that process or configure it to bind another port; killing it without identifying it can take down a production service.
Firewall rule did not survive a reboot
UFW and Windows Firewall keep rules across restarts. Raw iptables rules do not: save them with iptables-save or the netfilter-persistent package, and re-apply after upgrades that reset the ruleset.
The port is blocked but still reachable
A firewall rule filters inbound traffic; it does not close the listener. Confirm with the check command above and bind the service to 127.0.0.1 when only local clients need it.

Frequently asked questions
What is port 24922 used for?
Port 24922 (FIND) uses TCP / UDP. Find Identification of Network Devices.
How do I check if port 24922 is open?
On Linux run `sudo ss -tlpn 'sport = :24922'` and `sudo ss -ulpn 'sport = :24922'`. On Windows run `Get-NetTCPConnection -LocalPort 24922 -State Listen -ErrorAction SilentlyContinue` and `Get-NetUDPEndpoint -LocalPort 24922 -ErrorAction SilentlyContinue` in PowerShell. If the port is open, the output shows a process listening on port 24922; empty output usually means nothing is bound to it.
How do I block port 24922?
With UFW run `sudo ufw deny 24922/tcp` and `sudo ufw deny 24922/udp`. With iptables run `sudo iptables -A INPUT -p tcp --dport 24922 -j DROP` and `sudo iptables -A INPUT -p udp --dport 24922 -j DROP`. Persist the iptables rules with your distribution's netfilter-persistent or iptables-save tooling so they survive a reboot.
Is port 24922 safe to expose?
This port is not on our curated list of services with a widely exploited profile. Exposure is only safe when the listening service is intended, patched and protected by a firewall. Nevertheless, keep the listening service patched and remove it if unused. A default-deny firewall policy with explicit allow rules is still the safest baseline.
