ssh just needs to be able to run the sftp-server binary via the user's
/etc/passwd shell. You could either configure a restricted shell to only
allow running of sftp-server ie: smrsh (sendmail restricted shell) or you
can just set the user's shell to sftp-server so it automatically runs. The
second way should be okay.. the sshd will just run sftp-server with a
bunch of command line arguments like -fc /path/to/sftp-server (ie: as if
it were a shell ) but since sftp-server will just ignore that stuff it
should be fine and it'll be the same as if it had been run by a shell. I'd
probably still tend to use smrsh; it seems more `correct' somehow but the
other way should work fine and is good for lazyness =)
