Re: simulate connection with netcat

Thanks for all advises.
I actually don't need a full ssh implementation. The thing a wanted was =
a simple password-authentification for non-technical users without =
support for rsa-keys, remote execution etc.
But it sounds to complicated for a side-project...

Problem solved. Not quite the solution I hoped for but anyway...

regards,
jake
