    Hi,
     

    Sorry about the formatting of my previous e-mail, I am resending with
    more information in
    Text format this time.

    I am having problem with sftp(client running on windows and server
    running on solaris), although ssh works properly. I Cannot figure out
    anything.
     
    File transfer could not be started or it exited suddenly
    Exit value 0 was returned. Most likely the sftp-server is not in the
    path of the user on the server-side
     
    sftp-server is in the path, and also in the configuration file,
    /usr/local/etc/sshd_config
     
    I have checked the .profile and it does not have any echo statement or
    any program giving output.
     
    Version on windows(windows has ssh/sftp client only)
    -----------
    Version 3.2.1(Build 267)
     
    Version on solaris
    -----------
    OpenSSH_4.1p1, OpenSSL 0.9.7g 11 Apr 2005

    The following output is from sftp session connecting from one solaris
    box to another solaris box.
