[lwip-users] SSH-server for lwIP?

[Satz Klauer]

I know this is not a pure lwIP-question but may be somebody here
already solved this problem.

I need to implement a SSH-server on top of lwIP. Here I can't simply
use things like OpenSSH since it requires several functions from
underlying operating system (which normally does not exist when lwIP
is used).

So can anybody recommend a embedded SSH-implementation that can be
used on top of lwIP?

Thanks!
