[Pkg-cups-devel] Permissions for /usr/lib/cups/backend/{ipp, http, lpd}

[Martin Pitt]

Hi Hai,

Hai Zaar [2008-07-07 14:08 +0300]:
> 1. Why special restrictions are applied to ipp/lpd/http?

The backends with 700 permissions are executed as root, the
world-readable ones as user 'lp'. Most backends are fine with the
latter, but some need root privileges.

> 2. What are consequences of "chmod 755 /usr/lib/cups/backend/ipp"?

Then the backend won't be able to listen on the privileged port 631
any more, and IPP will be broken.
