X has been freezing, and then the machine completely locks up. There are other weird things like programs closing, programs locking up and not being able to be killed without sudo user privelages. I suspect there could be a memory issue - so I'm going to run a memtest. I am also going to do some updates - and just see if this will correct the problem. A little brief, but the word is now out ... let the fun begin. [RNZ] -------------- next part -------------- An HTML attachment was scrubbed...

I think this might be because nss-pam-ldapd (which we have to use because of GnuTLS library hilarity, and also because it is a bit better than the PADL LDAP NSS/PAM stuff) doesn't support chsh and chfn yet. It is in the development branch but that could be a few years away from hitting Debian stable.

There are several recordings at http://ucc.asn.au/tech/2013/0x05_tpg/ The high resolution video is still being compressed. The next talk is by Ranz Adamson, titled "Introduction to Ethical Hacking". It will be at 1:00pm in the UCC Clubroom, next Wednesday, 22nd May. We have a facebook event somewhere. Blurb: Ethical hacking is an area of Computer Science and Security Science that deals with finding and fixing security vulnerabilities in computer systems. We will discuss methods and the use of some tools for penetration testing and social engineering issues. These talks usually bring up all kinds of moral/ethics discussions, so we'll leave plenty of time for Q&A - and some interesting facts about privacy will also be revealed.

It sat stable around -90dB and only occasionally hit the better signal.When wireless dropped, it took about a minute to reconnect, when I got it to start reconnecting.The wireless link speed was only 5Mbps. When I eventually got speedtest to load, the results confirmed this.A ping test to Google's DNS server had about a 10% packet loss, and the pings where nowhere near stable. For comparison, from the bottom stair to the loft on the western side of the building, wireless signal was sitting stable around -75dB. I moved the wireless antennas so that they would both be covering Cameron Hall, but it did not improve the wireless signal in Unisfa. We can look at putting an access point in Unisfa and setting it up there, or finding something more powerful that will get signal through that wall. Also Note: I was looking at both the 2.4GHz and 5GHz channels. UCC-Public seems to have decent signal in Unisfa too.

The only difference between this and the $100+ DIR-825 that we have in UCC is that the D-Link supports both 2.4 GHz and 5 GHz channels. Presumably we would have both the UCC and UCC-Public SSIDs available. It is worth noting that in UCC we actually have two access points already - coromandel (DIR-825) and clearwing, an older WRT54GL. The UCC and UCC-Public SSIDs are separated over these two APs respectively, which means they can both have the full bandwidth available on their own channels. This would not happen in UniSFA if both SSIDs are available from the new AP. I see OpenWRT have just released a new version which (of course) has a new way of configuring the network.

Mmm, Java or LuCi, not sure which I prefer least.

Everything now runs the expert installer, because GUI installers make me break out in hives. 'debian' and 'debian-amd64' install wheezy (as do 'debian-wheezy' and 'debian-wheezy-amd64'). Testing is also around with 'debian-jessie' and 'debian-jessie-amd64'. The 'debian-testing' option and friends still work the way they used to, so who knows what they actually do. You can update the 'debian' and 'debian-amd64' items just by changing the symlink. Enjoy your slightly less out of date packages! -- David ([SLX]) From bob at ucc.gu.uwa.edu.au Sat May 25 01:11:21 2013 From: bob at ucc.gu.uwa.edu.au (Andrew Adamson) Date: Sat, 25 May 2013 01:11:21 +0800 (WST) Subject: [tech] Pinball Message-ID: I've reinstalled opensuse on pinball after I found an incomplete, nonfunctional install of debian sid on it. Sid is still there, but it's dual booting with suse as default. The SOE has been set up except for printing and good graphics drivers, which you kinda need to be there to install properly. If somebody could look after those two things when they have a moment that would be great. On a side note, opensuse seems to be getting fairly hard to make ldap work via yast, as yast wants you to use sssd (which I don't know and I'm unsure if it'll work with UCC's setup). I ended up just copying /etc/ldap.conf and /etc/nsswitch.conf off clownfish, installing the nss_ldap and pam_ldap packages, installing the ucc CA cert, and then it worked. Oh and I purged sssd from the system and it can DIAF.

Heathred was already running the testing versions of Wheezy and is now stabilised on 7.0 as well. All machines have been rebooted and have new kernels, including a fix for the rather nasty CVE-2013-2094. PostgreSQL and MySQL are running on the new versions; OpenLDAP has been upgraded. Medico remains on Debian 6.0 (Squeeze), because [BOB] threatened to break my fingers if I fiddled with his precious Proxmox install. There were a few hiccups along the way, mostly caused by old packages and config scripts. Many old packages have been removed. kexec is pure insanity. I enlarged Mussel's root partition during the reboot (Xen paravirtualised disks don't support this online). --- The following issues are outstanding AFAIK: Murasoi: The syslog-ng configuration format has changed AGAIN and it is complaining, though still working. We should update it. Mussel: The default webmail interface, horde3, has been killed off upstream and in Debian. The replacement horde4 isn't stabilised yet. For now, I have copied the contents of the packages to /usr/local/horde3 and it still works, but Horde is terrible. We should either work out how to migrate everyone from Horde to SoGo, or install and test horde4. There are still lots of obsolete packages installed on the machines that have been around for a while; careful removal might help in the long term. --- One of the more amusing problems was that Merlo refused to install the new version of grub, as the loader and support for both RAID and LVM didn't fit in the 512 bytes in front of the first partition. Today, I split the RAID and repartitioned the disks before reforming the RAID. Merlo now boots fine (thanks to [TPG] for getting it running with a USB stick) and incredibly all the disk stuff could be done online. Thanks to [MRD], [BOB], [TPG], [GOZ], [TRS] and [MSH] for helping to break and fix things respectively.

I'm just sending this email as a heads up that it's not as easy to tell when this filter is full - it's pretty fine and you need to take it out and hold it up to a light to see if it's blocked. I think somebody checked it the other day and declared it "good". The best way to clean it is under running water from the sink upstairs.
