Subject: sftp error on LynxOs


I am trying to initiate an sftp session from a Linux (Redhat) to a LynxOs
machine (where i have ported opnessh-2.9p1) and configured without PAM
support (as I was not able to find PAM version for LynxOS operating system)

I get the following error:
$ sftp -P /home/telica -l telica -v ben
select: Bad file descriptor
read: Input/output error
sftp>


Can somebody help me asap on this?

Thanks,Deepa.
