Hello!
I upgraded from 2.4.33.3 to 2.6.18 kernel. I am using UPS monitoring software, which forces system showtdown at power failure. At the first booting after the kernel upgrade the ups driver could not start, because it had no access to /dev/tts and all devices inside it. So I had to add to /etc/rc.d/rc.local the line: chmod -R 777 /dev/tts.
After that everything was ok until I noticed that at power failure the forced shutdown actually takes place only if I am logged in as root. If I am logged in as an ordinary user, no system shutdown takes place.
The system shutdown takes place after the command "upsmon -c fsd" is issued.

Obviously this is a permissions issue since if I am root and the power fails everything is ok. Besides, with the 2.4 kernel there was no need to "chmod -R 777 /dev/tts". I would be glad if someone tells me if there are permission differences when upgrading to kernel 2.6.18 and if so, to point some literuture to me on that.

I thank you in advance.

Regards,
Martin

The best solution here would be to run the daemon as root. It's not a good idea to chmod 777 all the tts device files.

For some reason, you have it starting as user, apparantly with your login.

The problem seems to be solved, although I still do not no how
This morning everything seems to work ok.
Thanks to all who read this thread
