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. Deepa N V Technical Support Engineer Telica Inc Marlborough,MA (W)508-804-8197
