SSH for BeOS
SSH by Andreas F. Bobak's port of Ylönen's v. 1.2.26. C source & binary. Issued under the latter (pre-1.2.28), gratis for noncommercial use, proprietary SSH 1.x licence. Client only; server code is included but is thus far non-functional. scp doesn't yet work, either. Build instructions are at a historical snapshot of Deirdre Saoirse Moen's site, http://web.archive.org/web/20000610105944/http://www.deirdre.net/ (unmaintained page). ssh protocol v. 1.5.
