It's running some Logitech USB thing (bought for us by rvvs89@, I think), so I had to add usbcore, uchi_hcd and gspca to /etc/modules, add usbfs to /etc/fstab, and rotate the camsource logfile (which had hit 2GB). The webcam could do with focusing. The easiest way is to stop camsource and run xawtv or similar on a nearby machine, but you need to be root to do both these things. Otherwise you someone can do it by making an adjustment and checking the webpage, but there's a 30 second delay there. We can also add another USB camera to the configuration, which I will try and remember to do after exams. Novorossiisk could still use some TLC.

Several of the UCC lists are configured to drop spam-tagged mail without administrator intervention (the list moderators get hundreds of messages a day as it is), so if you sent something to one of the lists from a non-UWA address in the last 12 hours you might want to resend it. This also applies to any external mail sent to support at .

There was a hypothesis that Xen couldn't handle high-volume serial traffic, so I used the serial line on Mermaid (Xen Dom0) for a while and sent large amounts of data through (strings /dev/urandom > /dev/ttyS1 &c.) but couldn't see any problems. In any case, I switched the vending machine from a serial connection to LAT (on port 6 on centipede, the DECserver in the machine room rack). It's not perfect - the keypress-display reaction is now noticeably slower - and I only waited about 20 minutes to see if it stopped working: needs probably 24 hours or so for a definitive "it works". ([DAG]: I had to bump LAT_VERSION in LATClient.py.) This should at least mean door group can stop rapelling into the clubroom.

I also pulled the capture card from maroon and put it back in to flying, so the B&W webcam can run again. o I rebooted manbo to b75, which went ok except that quite a few services were set to disabled, including ldap/client (causing Zanchey to not be able to log in) and nfs/server. I also enabled mdnsd, the port of Apple's zeroconf code which includes an evil wrapper for Avahi clients. Native CIFS [1] is coming soon, and might be worth a look. o Manbo's reboot allowed maroon to mount /home again. o The bug [2] in libnss-ldap we hit last year [3] was fixed 7 weeks later, so there's no reason to be using sarge's libnss-ldap any more. I didn't want to mess around with it, but we are using the etch version on mermaid without any problems, so it's probably safe to upgrade.

Apollo had some interesting quirks under 10.4 so the 10.5 install was a clean wipe and reinstall. I backed up the various games and apps on it, and they can be found in a disk image under /scratch/frenchie on martello. Quite a few of the reported problems (apps not starting etc) seem to have been fixed with the upgrade. Suspect we should also prod it in some way to lock it down and stop it sleeping as to stop it having any upsets with nfs. I ran out of time before being able to make it mount homedirs and talk ldap. Homedirs seem reasonably easy and nice to setup with the new Directory Utility revamp though what I did in that regard is completely untested.

Well, ARP for UCC won't work from there; ARP is used for local network MAC<->IP resolution. You're not local. :) I was doing it from madako the UCC router.

Thanks to MSH who rocked up and did what trs and I were too apathetic to do - take the case off a second time to reconnect the power button. Arctic has been reinstalled and has home directories and logins working although I'm yet to install any applications I'll do it tomorrow or thursday probably. As the disk is small once more, I won't install any major games, after-all, apollo will play them much better and arctic is probably better suited to a life as a web browsing box. Amusingly (well at least to me), arctic has found it's way into the same corner nautilus did when it was supplanted, bringing arctic full circle in it's life. Secondly, I've donated my old e-pc to the club as a small low power USB-webcam box. I setup ubuntu on it this evening (debian isos seem to have mysteriously vanished from mirrors.uwa and the ubuntu port has acquired some gremlins - a problem for another night). DAA then setup webcams on it remotely although the second of the logitech usb cameras appears to be partially busted and the other USB camera we've got makes it hard lock. Still, USB webcams aren't exactly _expensive_ so I might look at getting another one to go with it. Frenchie -- James French 0x21st UCC President frenchie at ucc.gu.uwa.edu.au From grahame at angrygoats.net Wed Nov 14 14:40:50 2007 From: grahame at angrygoats.net (Grahame Bowland) Date: Wed, 14 Nov 2007 14:40:50 +0900 Subject: [tech] Apollo speed Message-ID: I just had a play around with Apollo while having lunch, and I'm reasonably sure I found the reason it's so slow to use. The first clue was that it gets a lot faster if you wait around for twenty minutes. It's building a spotlight index of your NFS mounted home directory when you log in! Luckily it's not indexing everything; I guess they chucked something in 10.5 to notice when you have a network homedir and index _that_ but not the whole mount. The fix is to run: mdutil -i off `readlink "/home"`/`echo "$HOME"|sed 's/^\/home\///g'` when you log in. I'm don't know how to do it, but I'm sure one of those handsome Arts administrators knows where we can dump a shellscript with the above to run it on login. If you run it on a user that isn't logged in, it claims there isn't already an index; eg. we can't preemptively disable it for everyone, at least not in a way I can see.

I *think* this will work but I'm not sure if it will if the NFS export is mounted as a special folder and not a normal Volume.

This began sometime yesterday. Mail thus tagged is consequently stored in whichever mail folder is assigned to accept such mail on your system. ITS Communications staff are notifying the filter provider of the problem as it is not something we can correct ourselves.

WHAT SHOULD YOU DO: Please ensure all members of your department are made aware of the problem. Individuals who receive mail from hotmail addresses need to access the appropriate spam folder and check for real messages. Any real messages found should then be moved to the inbox.

SSDs (solid-state storage devices) typically have much, much faster seek times than hard disks since they don't have any (comparatively) slow moving parts. ([2] and [3]) However, my understanding is that for sustained reading and writing, a CF card wouldn't really stand up to a hard disk. (Some forms of flash memory do, but they're expensive.) Hard disks are reasonably quick when it comes to sustained transfer - between 40 and 75MiB/s for reading and writing, it seems. ([4] and [5]) Still, I think it's a good idea. I imagine that for everyday usage, a CF card would be just as good if not better than a hard disk, given the almost complete elimination of seek times and the fact that everyday usage (ie. not transferring gigabytes of games, porn, etc.) is not simply sustained reading and writing. Plus, there's a reduction in power consumption, increased reliability, and they don't make any noise or vibration. [1] http://www.pcengines.ch/cflash.htm [2] http://www.storagesearch.com/bitmicro-art3.html "The typical access time for a Flash based SSD is about 35 - 100 micro-seconds, whereas that of a rotating disk is around 5,000 - 10,000 micro-seconds. That makes a Flash-based SSD approximately 100 times faster than a rotating disk." [3] http://www23.tomshardware.com/storage.html?modelx=33&model1=117&model2=676&chart=32 New consumer-level hard disks have seek times ranging between 8 and 18ms.

This is the one day in 3 years when my users will really truly want it to be up and running. You could take the server offline for a week starting on Sunday for all I care. But I am pleading for a stay for troppo on Saturday. Cheers, JC.

There's nothing in the small rack that needs moving around, and the switching gear and firewall is unlikely to be prodded. I should probably explain that the cleanup was prompted by me getting stuck behind Manbo this afternoon and extricated by a surprised [LAW], so it's mainly about reducing the mess of cables behind the racks, tidying up the benches, and maybe doing something about the spaghetti-patchcabling. If we get overexcited we might even vacuum the floor.

Port 22 doesn't seem to get through anymore. One of the circuits in the machine room failed early this morning, taking down mermaid, mussel and mooneye and a few other machines. Power was restored at about 1pm this afternoon. -- # TRS-80 trs80(a)ucc.gu.uwa.edu.au #/ "Otherwise Bub here will do \ # UCC Wheel Member http://trs80.ucc.asn.au/ #| what squirrels do best | [ "There's nobody getting rich writing ]| -- Collect and hide your | [ software that I know of" -- Bill Gates, 1980 ]\ nuts." -- Acid Reflux #231 /
