https://bugzilla.novell.com/show_bug.cgi?id=235059 ------- Comment #7 from rschiele@gmail.com 2007-01-15 12:56 MST ------- Ludwig, I agree with you that allowing access to all parport devices by default is not a very good idea but 1. there should be a documented way (example config file) how a sysadmin can setup this _in an easy way_ if he likes to have it that way, 2. I can't see how you want to give access to the controller device directly --- contrary to USB devices from your example file these devices cannot be easily identified by probing for them, and 3. the documentation situation of all that hal/resmgr/udev is extremely bad, the way to "do things the right way" changes quite frequently in recent times without having appropriate migration documentation available --- for instance documentation for simple questions like "how can one grant access to a specific device in a persistent way" is just not available to the average sysadmin. --- Note that I don't claim it does not exist at all but it is (a) not in a place where the average user will expect to find it and (b) it's complexity level is not appropriate to answer these simple questions in an appropriate way. Actually I know a huge number of sysadmins that work around this hal/resmgr/udev stuff instead of making use of it and thus this is a regression for them compared to the old static device files. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=235059 ------- Comment #9 from rschiele@gmail.com 2007-01-16 02:25 MST ------- It's not that I am against the changes. --- Not at all. The problem with the documentation in the hal/resmgr/udev packages are mainly that (if existent) they describe and give examples for the shiny new features but basically don't explain how to do the things that were possible before in an easy way. The _specific_ and most annoying problem for most people I actually see in exactly the question Stefan had initially here in this thread: How does one change permissions for a specific device (named just by the device name and no additional magic) in a persistent way. A short simple step-by-step instruction would do as long as this is maintained over future changes. The current situation is more like giving a fancy modern VCR set to some old people not used to technology. When they ask how to record the current TV show on channel 2 you answer that it is not required to just record the current TV show because they could do programming their VCR over the internet instead of just telling them how to record the current TV show. In this thread you did exactly this: Instead of just answering Stefan's and Juergen's questions on how to change permissions for /dev/parportX you gave the advice not to do so. While giving this advice is fine it would be even better if you could just answer the question as well. The file you mentioned (/usr/share/doc/packages/hal-resmgr/README) does not really provide this information. Maybe actually the problem exactly _is_ that the people maintaining these packages typically know where to find all the information and thus don't see the problem any more. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Yes, we can work on this, but not by adding simply every device in sysfs to HAL.

If you want to go via group you have to add your own one. But then that's still retarded. The clean solution is via hal so ACLs can be used. Even then I'd in general vote against allowing users access to all parallel ports just because some package got installed (just like you don't start arbitrary deamons on package install). There could still be a printer connected to any of the available ports.
