i’ve been looking for openssh for windows for quite sometime. just stumbled across this today:
http://www.itefix.no/i2/copssh

i’ll try it out sometime soon.

update 11/9/09: tried it out on a winxp vm. it works fine, it’s actually not a native port but rather runs from within cygwin.

update 11/29/09: tried another alternative called “freessh”, it’s a lot more snazzier than copssh, but freessh is freeware and not OSS 🙁
