Dropbear SSH Review

Dropbear SSH Review

Unlike some of the other SCP servers we talked about Dropbear is Dropbear is particularly useful for “embedded”-type Linux (or other Unix) systems, such as wireless routers. It is a small SSH server and client that can run on a variety of POSIX- based platforms.

Using Dropbear SSH is best suited in the hands of an experienced system administrator, familiar with makefiles and recompiling the executable as needed.


  • Both a SSH server and client
  • Small memory footprint
  • Can run from inetd at startup or s a standalone server
  • Compatible with public key authentication from Open SSH


System Requirements

  • Linux – standard distributions, uClibc >=0.9.17, dietlibcmusl libc, uClinux from inetd
  • Mac OS X (compile with PAM support)
  • FreeBSD, NetBSD and OpenBSD
  • Solaris – tested v8 x86 and v9 Sparc
  • IRIX 6.5 (with /dev/urandom, or prngd should work)
  • Tru64 5.1 (using prngd for entropy)
  • AIX 4.3.3 (with gcc and Linux Affinity Toolkit), AIX 5.2 (with /dev/urandom).
  • HPUX 11.00 (+prngd), TCP forwarding doesn’t work
