Infrastructure Software

Hi, to setup a secure environment for file transfer, I have installed the following packages in my solaris 8.
- openssh-3.8
- openssl-0.9.7d-Solaris8-local
- prngd-0.9.26-Solaris8-local
- tcpwrappers-7.6-Solaris8-local
- zlib-1.2.1-Solaris8-local

I do not have any problem with SSH but I kept getting Connection Closed when I tried to sftp or scp into my Solaris 8. I have verified the user info is correct but have really no idea what is the problem. Following is the debug output from a windows client to my solaris 8:
