Today I have received an email informing me we have been afforded access to this. Have a lot of fun. Cheers, Gozz From 20492792 at student.uwa.edu.au Wed Jul 8 17:59:15 2015 From: 20492792 at student.uwa.edu.au (Andrew Seeley) Date: Wed, 8 Jul 2015 17:59:15 +0800 Subject: [tech] UCC's potential new 3D printer Message-ID: Greetings tech@ As many of you will know UCC has been looking into the viability of purchasing it's own 3D printer and with guild special project grants offering a large though not exact amount of money we are very interested in getting one. However the club does not want to invest in an expensive ( upwards of $1.5K) as many are hesitant about the idea as demand for such a machine from our members is not clear. If any members know of any especially good deals, have contacts or merely are interested with either using or tinkering with such a machine please feel free to email committee.

It will be held tomorrow night at 6pm in the UCC Clubroom, people will likely get dinner at some point in the evening. All those interested in learning about stuff are welcome to join in and help setup servers (including game servers) and giant masts (for some definition of giant).

I've removed ajaxterm, which previously lived at that URI. It's amazingly slick. It is set up with RDP to Maaxen (Windows) and Meersau (Linux), VNC to Gothamburg (OS X) and SSH to Motsugo (Linux). Setting it up was not so slick. There's a version in Debian, but it's a bit old and didn't work with our SSH server. I backported the guacamole-server package, but the mixture of Java, Maven and CDBS was too much for me to do guacamole-client. That's installed in /var/lib/tomcat7/ as guacamole.war. It's currently set up using "noauth", which should really be called session authentication, and the various connections are in /etc/guacamole/noauth-config.xml. When we get Apache 2.4 on Mussel (i.e. when someone upgrades it to Debian 8), we gain access to websockets which might improve performance a bit.

Most things that we want from ETPub are there already, although it's hard to confirm as they're not exposed as cvars. I've chmod -x the files on heathred, and have set up a port redirect on murasoi to redirect connections to the ET VM. Although we might want to re-ip it, as it's 130.95.13.15 which is in the UNFIREWALLED range. Also I removed tntnet and installed apache2, and got the stats working again. -- # 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 / From mattwins at westnet.com.au Wed Jul 22 17:02:49 2015 From: mattwins at westnet.com.au (Matthew Winslade) Date: Wed, 22 Jul 2015 17:02:49 +0800 Subject: [tech] Critical Electrical Works Message-ID: <976685589384e3e8019e0695a6bddeb931b582c4@webmail.westnet.com.au> tech@ A bunch of poster/papers have been posted around Cameron Hall regarding 'Critical Electrical Works' from Friday the 24th to Sunday the 16th.

I'm not too familiar with the internals of the OOM killer but for whatever reason it wasn't triggering. This made it hard to be certain what was going on because I got lots of: root at mussel ~# df -h Could not create child process - exiting fork: Cannot allocate memory mussel:~# service sogo stop -bash: fork: Cannot allocate memory mussel:~# cat /proc/meminfo -bash: fork: Cannot allocate memory mussel:~# cd /proc mussel:/proc# ls -bash: fork: Cannot allocate memory When I saw this happen the other day I managed to get top running which showed Sogo using most of the memory. The logs are full of: sogod[25376] Problem posting notification: NAME:NSMallocException REASON:Default zone has run out of memory INFO:(null) I killed process 25376 and everything came back properly. Then I ran `logrotate -f /etc/logrotate.d/sogo` to compress the 2.0GB log file and now we have some free space. The remaining sogo process was still trying to eat a fair bit of RAM: 23244 sogo 20 0 980m 929m 720 S 0 23.0 1:54.53 sogod I've left sogo stopped for now. Perhaps someone who actually uses it could try rolling back to the last version, or put it under ulimit or something? [DAA] zanchey@
