quick one--umaske for 777?

[Joe Szilagyi]

Thanks all! Setting umask 000 on the one user only netted files with 666.
It's a restricted user with a password, for uploading graphics--that user is
simply segregated from the main domain, and the primary username in the
group needed to be able to read/write files easily that were owned by the
alternate user without any chowning/cronning solutions possible. That did
it, thanks!

Regards,
Joe

AFAIK this can't be done.

Umask of 000 would theoretically produce what you want, but linux
refuses to create files that are executable for security reasons.  The
best it will allow is 666 on the files uploaded.  A quick proof of that
would be to set your own umask to 000 then create a new file and look at
the permissions.

Allowing uploaded files to have mode 777 with a public FTP site would be
one of the worst mistakes I can think of because it would allow anyone
to put an executable file in your ftp site that could be then executed
for the creators purpose, what ever that may be (and usually not for
your benefit)

It may be possible to have ftp run a script when the upload completes to
set the mode, or to modify the program itself to do that, or to have
cron reset the mode on all files periodically.
