Hey that did it!!! Thanks!!! In cygwin I did an ls -laR and confirmed the
directory had d------ privileges. The first attempt to chmod -R 775 failed,
then I restarted cygwin with "Run As Administrator" and it worked. The
first attempt to rsync then failed because the folder up there on the Linux
machine was still set to d------ from the last attempt... so I went in and
chmod'd that to 755 (not 775, deliberately different)... then tried the
rsync again... hummed along no problems, then after completion I went back
to the Linux machine and the test files were all there and the privileges
for the folder had been changed from 755 to 775 (drwxrwxr-x)... perfect.
So... two interesting followon points...
1. Why didn't the ACLs get set to something reasonable as opposed to 000 in
the first place when I created this little test area in Vista? After all, I
could do directory listings even in cygwin, so it seems a bit of an unfair
trick on me that the access was actually set to 000... In fact, thinking
about it, I guess it inherited the 000 from the parent c:\ directory. But
just seems a bit odd to me that I ended up with this 000 setting which in
unix systems means one cannot even do an ls yet I was totally unaware of it
and able to see all the files
2. Given the above, and Igor's comments that rsync will not copy ACLs, why
in the world did rsync copy the strange 000 flags... hmmm... not sure about
this, in a way it is 100% correct to do that, but maybe there should be
(maybe there already is??) a flag on rsync which stops it setting
permissions during the transfers.
Having made these observations, I must say that in my case the problem is
now 100% solved by Igor's suggestion... I will simply do that chmod 775 -R
to all my file trees I intend to sync in future. But this sure is a trap
for the innocent... thanks again Igor
