Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… This is an appropriate list for your question. Your iBook isn't idle sleeping, and there are a few things to check out to try to debug why it isn't idle sleeping. - Run "pmset -g" to see what the idle sleep settings are. sleep, displaysleep, and disksleep should all be small numbers. They should not be 0, because 0 means never here. - Try setting a quick sleep and measure how long it takes to occur "sudo pmset -b displaysleep 1 disksleep 1 sleep 1" - that will make the machine idle sleep after 1 minute of inactivity. In practice on a quiet system, sleep would probably occur around the 90 - 120 second range. It's very imprecise, since the timing is tied to disk I/O. Setting the sleep timer (all of the sleep timers) to 1 minute can help isolate the problem. Does it still occur at this point? Things that can prevent system sleep: - Disk I/O every minute will prevent sleep. If any app periodically writes a few bytes to a local hard disk, that disk won't ever be able to spin down. Disks require 1 solid minute without I/O to spindown. - If the sleep timer has expired, as soon as the disks spin down the system will idle sleep. - Any app can prevent idle sleep via IOKit sleep API. So start killing apps and see if that makes it better. If you want to track down which app is causing disk activity, set your display to never sleep, run this as root: "fs_usage -f filesys", and quietly sit there and watch. Is a particular application or background process gobbling disk I/O's? this is my first post to this list, so first I'd like to introduce myself. My name is ronny and I'm currently a student of computer science at the Technical University of Ilmenau. Now that that's out of the way... Since a few days my iBook G4 (1.2GHz 12") has problems falling asleep after the specified amount of time. I will need to conduct more tests but it currently only seems to happen when running under battery power. (At least I found the computer sleeping yesterday after leaving it for some time when it was on AC power.) The reason why I ask this on this list is: Are there some tools available, either included in the system or third party (preferably free) that can help me debug the problem? I can't find any information in the logs and frankly at the moment I'm lost. If there is a more appropriate place to ask this question (please no Internet user forums or support centers), I'd appreciate some pointers. Thank you for any help you could provide.

Re: Charset-Conversion for NFS-Mounts

It's a complete shot in the dark, but I'd probably first try to add conversion to NFS itself (it's open source, and the necessary APIs are described in the technote I mentioned). Hopefully, others will give a more informed advice. - WBR, Alexey Proskuryakov _______________________________________________ Do not post admin requests to the list. They will be ignored.

Consequently, I tried determine whether NFS-Mounts support charset conversion, in the way HFS or SMB mounts do. So far my search revealed nothing. Have you read <http://developer.apple.com/qa/qa2001/qa1173.html>? I'm aware of the problem with NFS (decomposed/precomposed). What I'm looking for is a way to convert the charset during an NFS access, so the server sees charset X while a MacOSX client still can deal with decomposed Unicode. As far as I've seen, NFS does not have such a conversion builtin. Could this be implemented in form of a filter file system?
