Dropbear stellt eine (ebenfalls freie) Alternative zum OpenSSH-Server und -Client dar. Dropbear wurde von Matt Johnston speziell für Arbeitsumgebungen ausgelegt, die wenig Speicher- und/oder Prozessorresourcen zur Verfügung stellen (siehe: Eingebettetes System).

Inhaltsverzeichnis

Technologie

Dropbear stellt eine vollständige Implementierung des Protokolls der Version 2 der Secure Shell (SSH2) dar.

Die kryptographischen Algorithmen verwenden intern einige Kryptographie-Bibliotheken von anderen Open-Source-Paketen.[1]

Eigenschaften

Dropbear stellt eine vollständige Implementierung des SSH2-Protokolls dar – sowohl die des Clients als auch des Servers. Die Version 1 des SSH-Protokolls wurde nicht implementiert: In erster Linie dient dies um einen schlanken Ausführungsprogrammcode zu erhalten, Betriebsmittel zu sparen und um bekannte Sicherheitsrisiken in SSH Version 1 zu umgehen[2].
