Port 5269: XMPP server
Port 5269 is used for server-to-server XMPP federation, letting users on one XMPP server message users on a different server, similar to how email servers relay mail between domains.
| Port number | 5269 |
|---|---|
| Service | XMPP server-to-server |
| Protocol | TCP |
| Category | Chat & messaging |
| Default encryption | No |
How do I check whether port 5269 is open?
Port 5269 carries TCP, so a connection either completes its handshake or it does not, which makes the check definitive.
| Question | Command | What to know |
|---|---|---|
| Is it open on a remote host? | nc -vz example.com 5269 | A TCP handshake either completes or it does not, so netcat gives a definitive answer in one line. |
| Same check on Windows | Test-NetConnection example.com -Port 5269 | Built into PowerShell. TcpTestSucceeded in the output is the answer; telnet is not installed by default on modern Windows. |
| What is listening locally? | ss -tlnp | grep ':5269 ' | Lists the process bound to port 5269 on Linux. On macOS use lsof -nP -iTCP:5269 -sTCP:LISTEN, on Windows netstat -ano | findstr :5269 |
Replace example.com with the host you are testing. A blocked port and a port with nothing listening on it look identical from the outside, so if a service should be running, check locally before blaming the firewall.
