Dropbear is a relatively small SSH server and client. It runs on a variety of POSIX-based platforms. Dropbear is open source software, distributed under a MIT-style license. Dropbear is particularly useful for "embedded"-type Linux (or other Unix) systems, such as wireless routers.
If you want to be notified of new releases, or for general discussion of Dropbear, you can subscribe to the relatively low volume mailing list.
Security update: Dropbear 2013.59 fixes a memory exhaustion denial-of-service and avoids disclosing which users are valid.
It shouldn't be hard to get it to work on other POSIX platforms, it is mostly a case of setting up the configure and Makefile settings.
Please let me know of any others which should be added to this list.
The cryptographic code utilises Tom St Denis's LibTomCrypt, and uses his LibTomMath library for the bignum parts. PTY handling code is taken from OpenSSH (from Tatu Ylönen's original ssh), login recording (utmp/wtmp) code is from OpenSSH by Andre Lucas, and some implementation details were gleaned from PuTTY. Numerous people have contributed patches and bug reports, see CHANGES. Particular thanks go to Mihnea Stoenescu for his work on the client portion.
Thanks to PCextreme for hosting the mirror server with Raspberry Pi colocation.
