Most of the log messages scroll off the screen. Unfortunately, xinetd
insists on outputing it's messages to the 'tty', even if stderr is
redirected to a file
or a pipe. However, I did manage to cut and paste the error.
Normally, I would expect that this error means I don't have Administrator
privledges, but of course I do. I can't say if this is the same error that
occures when
xinetd is started by init, since error messages go to the bit bucket instead
of the log file.
However, the behavior of the xinetd is the same in both cases...
For the most part, I'm using an unmodified passwd file generated by
"mkpasswd", so naturally I am not using 65535 as a user id. I have to
admit, I do not really under stand the usage of
the cygwin /etc/passwd file under cygwin. The file ownerships, and
permissions appear to be like unix. But try the following:
ssh -l bar localhost 'echo hi > /foo.txt;chmod 700 /foo.txt;chown fi
/foo.txt'
ssh -l fi localhost 'cat /foo.txt'
Even if both 'bar', and 'fi' have administrator permissions, this results in
a permission denied error. Furtermore:
ssh -l bar localhost 'echo hi > /foo.txt;chmod 700 /foo.txt;chown fi
/foo.txt'
ssh -l fi localhost 'chmod 777 /foo.txt;cp /foo.txt /foo2.txt;mv
/foo2.txt /foo.txt; \
chmod 700 /foo.txt;cat foo.txt'
works without error.
I find crazy things, like the CYGWIN FAQ claims 'su.exe' does not exist
under cygwin, unless you have a really old distribution. Which false...
But it says if you do have 'su.exe' it probably doesn't work. That part is
true. So, studying the documentation isn't helping in learning how file
permissions and such really work under cygwin.
