 |

Hya
I've recently tried to set permissions of artsd and artswrapper to suid root. The reason for this is that certain games have a nasty latency that I can't get out without either bypassing artsd and run directly on ALSA (and therefore muting all other apps), or by shutting down arts altogether (making things even worse - ALSA doesn't support hardware mixing on intel8x0?)
Anywayz, when I set the perms to suid root, I restarted it, and then I got a nasty error, saying that /tmp/mcop-root was inaccesible (I'm sorry that I haven't written it down, but I got mad on the thing for screwing up my artsrc in my KDE-profile as well).
That directory /tmp/mcop-root, to whom should it be accesible to: root or myself, or both?

Disclaimer: I could be way off here, so be responsible for your own actions.
However, I would probably | Code: | | rm -rf /tmp/* && chmod -r 666 /tmp |
I mean, the tmp directory is *supposed* to be temporary, anyway.

Yes, black magic doesn't use parentheses.

Okay, I retried to suid'ing artsd, and I also set the permissions of /tmp/mcop-root to world rwx + I made my user (lunarg) owner of the dir because artsd was complaining about that too:
| Code: | | drwxrwxrwx 3 lunarg users 112 Feb 12 22:12 mcop-root |
When I start it now, I get the strangest error message.... 
| Quote: | | /tmp/mcop-root is accessible owned by user |
What does that one mean? Artsd won't start up.....

Why don't you just delete the whole directory, and then restart the daemon?

Removed the dir /tmp/mcop-root.
It gets recreated with these permissions:
| Code: | | drwx------ 2 root users 48 Feb 22 23:54 mcop-root |
And then I get the error again as I started with:
| Quote: | | /tmp/mcop-root is not owned by user |

Oops 
After visiting arts-project.org, I found out that it's not artsd that needs to be suid root, but artswrapper....
Sorry guys.... It seems to work now.
