포트115— Simple File Transfer Protocol
IANA는 과거의 Simple File Transfer Protocol에 TCP 115를 할당했습니다. 약어 SFTP를 SSH File Transfer Protocol과 혼동하면 안 됩니다.
Registry assignments, software defaults and local listeners are different things. A port number alone does not identify or secure a service.
Configuration and troubleshooting
SSH 파일 전송 클라이언트에서는 SSH 서버 엔드포인트를 확인하며 보통 22부터 점검합니다. 115를 열어도 SSH 기반 SFTP가 활성화되지는 않습니다.
Important limitations
과거의 포트 할당 기록은 호스트에서 해당 프로토콜이 실행 중이거나 최신 소프트웨어가 이 포트를 사용해야 한다는 뜻이 아닙니다.
Read-only checks: run on the server host
Choose the commands for your OS. Check TCP and UDP separately. No result is not a lasting availability guarantee; inspect host and container separately.

Simple File Transfer Protocol (historical)
IANA assigns TCP 115 to the historical Simple File Transfer Protocol. Its SFTP abbreviation must not be confused with SSH File Transfer Protocol.
사용 시 참고 사항
- 포트 115 사용 전에 다른 서비스가 점유하고 있지 않은지 확인해 주세요
- 포트 충돌이 발생하면 다른 포트를 사용하거나 해당 포트를 점유한 서비스를 중지하는 것을 고려해 보세요
자주 묻는 질문
What is port 115 used for?
Port 115 sits in the File Sharing category. This page lists the registered purpose and the software commonly associated with it; to see what is actually listening on a specific machine, check the process with ss/netstat.
Is port 115 TCP or UDP?
The registered protocol on this page is TCP. The same number behaves independently on each protocol: TCP may be listening while UDP is idle, so check them separately.
How do I check if port 115 is in use?
On Linux: sudo ss -tlnp 'sport = :115' for an exact port match. On macOS: sudo lsof -nP -iTCP:115 -sTCP:LISTEN. On Windows PowerShell: Get-NetTCPConnection -LocalPort 115 -State Listen. A listener counts as confirmed only when you can see the bind address and process name; without root/admin you will not see other users' processes.
Is port 115 secure? Should I open it in my firewall?
A port number has no inherent security — it depends on whether the listening service is correctly configured and whether it needs exposure at all. Keep loopback/internal-only services firewalled; where public access is required, pair it with source restrictions, VPN or authentication. The caution section on this page lists port-specific risks.
