Hi guy's,

I've been trying to make sftp work with OpenSSH_3.5p1 on my tru64 4.0G server.

SSH works fine, but when I try to use the subsystem all I get is connection closed. I tryed whats on the faq:
ssh <sever> /usr/bin/true and all I get is a list of my enviroment.

Using the client with -vvv I get the following:

stssema1: > sftp -v stssema2

Any ideas on what the problem could be??
Thanks in advance
