{"guid":"86a97c61-8362-40af-9934-821d04f08ccd","title":"curl: Mehr als HTTP","subtitle":"Protokollübergreifendes Troubleshooting","slug":"froscon2026-3540-curl_mehr_als_http","link":"https://programm.froscon.org/2026/events/3540.html","description":"curl ist das Schweizer Taschenmesser für Netzwerkprotokolle – plattformübergreifend auf Windows, macOS und Linux verfügbar. Dieser Vortrag zeigt, wie Admins und Developer curl weit über HTTP/HTTPS hinaus für die Fehlersuche in modernen Infrastrukturen einsetzen können: von Kubernetes Ingress über SMTP und LDAP bis hin zu API-Debugging und TLS-Vergleichen.\n\ncurl ist in jeder Infrastruktur vorhanden – und wird dennoch meist nur als HTTP-Client verwendet. Dabei steckt in diesem kleinen Tool weit mehr: curl beherrscht Dutzende Protokolle und ist damit das ideale, plattformunabhängige Werkzeug für die Fehlersuche im Alltag.\nDieser praxisorientierte Vortrag zeigt anhand realer Problemstellungen, wie curl für typische Admin- und Entwickleraufgaben eingesetzt werden kann:\n\nTest und Debugging von REST-APIs (PUT, POST, OPTIONS, Header-Analyse)\nÜberprüfung von Ingress-Konfigurationen in Kubernetes-Umgebungen\nVersand von Test-E-Mails direkt über SMTP – ohne Mailclient\nAusführung und Analyse von LDAP-Queries\nVergleich von HTTP- vs. HTTPS-Verbindungen und TLS-Zertifikat-Debugging\nVerbose-Output lesen und verstehen: Was curl wirklich sagt\n\nAlle Beispiele stammen aus dem echten Supportalltag und sind sofort in der eigenen Umgebung nachvollziehbar. Wer curl bisher nur für curl https://example.com benutzt hat, wird diesen Talk mit einem deutlich erweiterten Werkzeugkasten verlassen.\n\nLicensed to the public under
