Port 6514: Syslog-TLS
Port 6514 is syslog over TLS, the encrypted version of the plain UDP syslog on port 514. It protects log data in transit, which matters because syslog messages often include sensitive details about system events.
| Port number | 6514 |
|---|---|
| Service | Syslog over TLS |
| Protocol | TCP |
| Category | Management |
| Default encryption | Yes (TLS/SSH) |
How do I check whether port 6514 is open?
Port 6514 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 6514 | 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 6514 | 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 ':6514 ' | Lists the process bound to port 6514 on Linux. On macOS use lsof -nP -iTCP:6514 -sTCP:LISTEN, on Windows netstat -ano | findstr :6514 |
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.
Frequently asked questions
What is port 6514 used for?
Port 6514 is syslog over TLS, the encrypted version of the plain UDP syslog on port 514. It protects log data in transit, which matters because syslog messages often include sensitive details about system events.
Is port 6514 TCP or UDP?
Port 6514 (Syslog-TLS) uses TCP.
Is port 6514 secure?
Yes. Port 6514 carries encrypted traffic by default, so data in transit is protected.
Should I open port 6514 on my firewall?
Only if you specifically need Syslog-TLS. Expose it to the smallest set of trusted sources, and never open database or Windows-service ports to the whole internet.
