I've just started using BOINC and will try using video cards soon. Donations of old PCIe video cards to the hardware library will be good, especially if other people also start using BOINC. I'll probably give a talk about BOINC at a future LUV meeting. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Jabber
by Russell Coker 22 May '16

The Jabber address letmein(a)luv.asn.au will be monitored by multiple committee members. If you have problems finding a meeting or getting in then you can contact that address. An advantage of using Jabber over the mobile phone is that multiple people can use it and that the Jabber "status" can convey useful information. A Jabber status of "sorry the guy with the key missed his bus, will start the meeting 1 hour late" would be better than just wondering what's happening. Please only use that address for problems getting to meetings. The Jabber address president(a)luv.asn.au will be used for official presidential duties. Please don't use it for anything for which email will do. Currently we are having problems finding speakers for future meetings. If you find someone who's capable of giving a good lecture and interested in doing so then please Jabber the president if an immediate contact will help lock it in. https://play.google.com/store/apps/details?id=com.xabber.android https://f-droid.org/repository/browse/?fdfilter=xabber I use Xabber on my phone to read Jabber messages, Xabber is in the Play Store and the F-Droid free repository. F-Droid allows you to download the source and install any version you like. There are many free Jabber servers out there, a Google search will turn up lists of them. It's easy to run Prosody (at the bottom of this message is a quick summary of config file changes necessary). Also we can offer @luv.asn.au accounts to LUV members, but note that account names like "root" will not be provided and accounts will be cancelled for misuse. To setup Prosody first put your address in admins section in /etc/prosody/prosody.cfg.lua: admins = { "sysadmin(a)example.com" } Get a certificate with Letsencrypt and set it like the following: ssl = { key = "/etc/letsencrypt/live/www.example.com/privkey.pem"; certificate = "/etc/letsencrypt/live/www.example.com/fullchain.pem"; } Set a VirtualHost then restart the server: VirtualHost "example.com" Add DNS entries like the following: _xmpp-server._tcp IN SRV 0 5 5269 jabber.example.com. _xmpp-client._tcp IN SRV 0 5 5222 jabber.example.com. Add accounts with "prosodyctl adduser USER(a)example.com" -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Who owns Android ?
by Rohan McLeod 17 May '16

17 May '16

Gathered illuminati; seems to be a curious silence on the question who 'owns' Android; at the heart of an $A8billion dispute between Oracle and Google; which has re-surfaced this week -To what extent can open source software be 'owned' ? -To what extent can a particular distribution of a piece of open-source software be 'owned' ? -To what extent can API's be 'owned' ? regards Rohan McLeod

I started work on re-using these devices ages ago and have a new burst of energy with them. Anyone else interested in re-using these? Mike

initramfs and USB sticks that won't boot
by Allan Duncan 09 May '16

09 May '16

I have a number of bootable USB sticks, all 32 bit. These work fine on all my boxes, and work quite well with the one box that will actually _boot_ USB3. I would like to do a 64 bit variant of this and just tweaked an existing system to fit onto a 16 G USB stick. This starts off booting and then times out because it can't find the root device. Delving around in the minimalist emergency environment shows that the USB device is indeed not present - blkid shows all the other devices. The normal boot uses UUID identifiers and non-EFI. The kernel in the initramfs has all the USB drivers builtin. Btw - is there an easy way to unpick initramfs - I found I needed to lop off the uncompressed leading cpio to get at the gzipped cpio filesystem that followed? Any suggestions? Please.

Another thing that there is demand for is DisplayPort cables that have full- size connectors at both ends (we have a heap of cables with a mini-DP connector at one end) and HDMI cables. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

At the moment we could really do with some donations of DDR3 RAM to the Hardware Library. In particular we need 4G DDR3 DIMMs for the systems that are used for running training sessions. We have some plans for training sessions at the Beginners' SIG meetings that require more RAM. Also for the hardware library there is ongoing interest in SATA disks and ATI PCIe video cards. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

strange TCP problem looks like PMTU but isn't
by Russell Coker 30 Apr '16

30 Apr '16

I've got a Linux system running remotely that has a strange TCP problem, when it sends (not receives) a large packet the connection hangs. For example if I ssh in and run commands with small amounts of output everything is fine, but if I run "ls -l /" then the connection hangs forever. My first thought was PMTU discovery, but "ping -M want -s 1400 8.8.8.8" works without any problems and also setting the MTU on the only Ethernet device to unusually low values (I tried as low as 400 bytes) didn't make any difference. Any ideas as to what I should try next? The system in question is a fairly standard AMD64 desktop PC running Debian/Jessie. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
