Hi,
is the sftp subserver enabled at the server side? Examine the "Subsystem" configuration in sshd_config.
I once saw (on AIX) that the sftp-server binary had explicitly to be made executable (by means of 'chmod +x'), as it was shipped without that flag.

i noticed /usr/libexec/sftp-server doesn't exist, but /usr/lib/sftp-server does. i will try changing it over.

i am getting some other premissions error now when editing sshd_config, but i will report back when i have it changed.
