sftp : have to specify subsystem from client side
I have several ssh servers *running aix 5.3 and they respond to sftp requests just fine, but I have one that requires clients to specify the path to the sftp server using the -s flag which is*/usr/sbin/sftp-server

I check the sshd_config across all servers and they are the same. *The other servers I*don't' have to do this. *Any ideas what I*should*be looking for?

Thanks in advance.

Here is the debug output from the client side:

Typically, /usr/sbin/ will not be included in the PATH of the most basic shell environments. Try modifying the startup script for sshd and adding that directory to the PATH before starting the sshd daemon and see if that fixes your issue.
