Häufig gestellte Fragen
Wofür wird Port 443 verwendet?
Port 443 ist der Standardport für HTTPS — mit TLS/SSL verschlüsselter Webverkehr. Praktisch jede moderne Website und API nutzt ihn.
Was ist der Unterschied zwischen Port 80 und 8080?
Port 80 ist der offizielle HTTP-Port. Port 8080 ist eine inoffizielle Alternative für Dev-Server, Proxys und Admin-Oberflächen wie Tomcat.
Welchen Port verwendet SSH?
SSH verwendet TCP-Port 22. Über denselben Port laufen auch SFTP-Dateitransfers und SSH-Tunnel.
Port 465 oder 587 zum E-Mail-Versand?
Port 587 mit STARTTLS ist der empfohlene Port für die E-Mail-Einreichung. Port 465 (implizites TLS) ist ebenfalls wieder standardisiert; Port 25 dient nur der Server-zu-Server-Weiterleitung.
