When mail was addressed to a non-existent user (even a user in an invalid domain) a bounce message would be sent to the From: field as well as CC: fields. I think it also used the To: field in the original message (even if obviously faked) as the From: field in the bounce. It appeared that I could have trivially made two Lotus servers attack each other in a recursive manner, but I resisted the temptation to make two IBM servers DoS each other so I'll never know for sure. The Lotus email system was written by people who fundamentally don't understand email and were too lazy to read the standards documents. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

That has certainly given me a lot of ideas. Buying a ready made box would be good but I haven't found anything to match my specs yet will keep looking. Thank you for all the suggestions both of people to buy from and those to avoid.

New SuSe 12.1
by Andrew Greig 03 Apr '12

03 Apr '12

Hi All, I wanted to contribute an opinion of the new SuSe 12.1 (it has been out for a couple of months now), but before that, a bit of background. I have been a Mandrake/Mandriva user for many years and although I have trialled a few other distros (Red Hat, Fedora, Debian, Ubuntu, Kubuntu, Mint, Slackware, among them), I have always returned to Mandriva for its outstanding configuration of attached hardware. When doing the install, get everything you own attached and turned on and it will most likely be configured and be ready for use, when the install completes. This WAS my experience, it just worked. Considering that my Linux box was driving my business I could not afford to stuff around when I wanted to upgrade. I recently discovered the joys of mapping under Linux (QlandkarteGT) but Mandriva was way behind the dev cycle and I needed to be running later versions of QLGT. So I switched to SuSe 11.4, and in general it was OK, but the dev of QLGT also happened to be the package maintainer for it so the RPMs were fresh and slick. And I ran with that for quite a while. And then I thought, "I'll see how Mandriva is doing lately" and I downloaded my "paid for" power pack subscription DVD, and installed it with both KDE and gnome. I was really surprised, I have never seen anything so bad emerge from that brand before, so much was broken, including QLGT. It lasted 24 hours. Next night I installed the Gnome version of the Suse 12.1 release, and I cannot see myself returning to KDE again. It has a clever blend of conventional desktop with the "App" style of a tablet or smart phone. There is a small "Favourites" bar down the left side of the screen, and all of the windows in use are shrunk and presented in one view, if you want something different Clicking on "Applications will display the full set with subset options down the right hand side. When you get used to this, it is a very fast way to get around. I had some initial difficulty getting my two screens to work properly, just a learning curve. But hey!, I love this green piece of German engineering, 9.5/10 from me. Andrew Greig

strange SpamAssassin errors
by Russell Coker 03 Apr '12

user_scores_sql_custom_query SELECT IF(type = 'WHITE', 'whitelist_from', 'blacklist_from') AS preference, IF(INSTR(email, '@'),email,CONCAT('*@', email)) AS value FROM lists WHERE uid = _USERNAME_ ORDER BY preference ASC I'm getting lots of errors like those at the bottom of this message in my logs.

Can anyone on the list give me any recommendations for online stores to buy computer parts or for that matter warnings of places to avoid. I am looking to build my first system since coming to this country and don't know any of the suppliers. I always used to use http://www.ebuyer.com when I was in the UK and am looking for something similar in Melbourne. Stripes.

jpeg file weirdness
by Brian May 26 Mar '12

26 Mar '12

Hello, I have an Apache server that serves a large static jpeg file. It originally came from a scanned photo. Most programs display this fine, including Firefox and Chromium that come with the latest Ubuntu. If I look at the file, I can't see any signs of missing regions or other corruption (not including spots from the original scanned image of course). Firefox under windows displays a message that the image cannot be displayed due to errors. Android 2.3.4 running on my Galaxy S2. says "An internal server error occurred. Please try again later." which is nonsense, as the apache log file says the server provided the file without errors. Programs like Gimp, gthumb, and display all seem to load the file ok. Any ideas? -- Brian May <brian(a)microcomaustralia.com.au>

Unable to install Linux (Debian, Ubuntu and Mint) on to laptop
by Tim Lyth 26 Mar '12

26 Mar '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I have tried to get the installation process for each of the three distros mentioned in the subject to install on to my Laptop. Ubunutu and Mint both fail when trying to modprobe hardware just after detecting the hard drives. Debian (using the NetInst 6.0.4 CD) gets in to the installer but can't detect either the GigE network card nor then Wifi card that are in my laptop. The GigE card is an Atheros AR8151 NIC. I've googled for suggestions, it appears that the 'atl1c' and/or 'atl1e' driver should do it, but the version of both included on the Debian install CD doesn't help the installer detect the NIC. I've not yet started on trying to figure out the WiFi card, as I was hoping to get the NIC working, install Linux and then build a custom kernel with the WiFi driver I need. The Debian NetInst CD runs kernel 2.6.32, but does offer me the option of installing modules off removable media. What I don't know is what files, file names, and the like I'd need to have on a USB memory stick to do that. And then I'd also need to actually get the required files. The Atheros NIC uses VENDOR ID: 1969 and DEVICE ID: 1083. I am tempted to install Virtualbox on to my laptop, install Linux in there, and then build a custom kernel with the correct drivers, but I would prefer to avoid that if possible. Can anyone assist me, by providing a link to the appropriate files, so that I can put them on to a USB memory stick and get Debian on to my laptop? Alternatively, advise on other Linux distro's installers which DO support the AR8151 would be appreciated. I would prefer to stick to the Debian family.

XBMC, lirc, remotes, harmony?
by Brett Pemberton 26 Mar '12

26 Mar '12

Hi, I have a pretty simple remote setup that I wanted to replace with a Harmony 650, as they were on special. However I haven't been able to get it going, since I've been working off many partial tutorials. Wondering if anyone here has some advice. I'm running XBMC Eden on Ubuntu Oneiric. I have a similar desktop I'm testing this new remote on, with the goal of switching it over on the actual HTPC once I have a working setup. I have 3 receivers to choose from. 1) A $20 'mce compatible' remote I got from Dick Smith. It just sends keyboard events, which work great right now with XBMC, no need for lirc. 2) A TwinHan receiver, as documented here: http://www.doctort.org/adam/general/update-on-twinhan-remote-for-mythbuntu-… I believe it's quite flakey. I did get it to work using lirc as documented on that webpage, but it broke on an upgrade at one point, hence replacing it with the system above. 3) A HP OVU400102, which I thought from reading was the most compatible with the Harmony, and setup would be a piece of cake. It hasn't been. As I said, I've found many 'partial' tutorials, mostly people posting on XBMC forums with similar setups. I've run dpkg-reconfigure lirc more times than I can count, hand edited hardware.conf too many times, laughed at: lircd-0.9.0[8283]: you are using an obsolete devinput config file: Success lircd-0.9.0[8283]: get the new version at http://lirc.sourceforge.net/remotes/devinput/lircd.conf.devinput: Success this a few times. Right now, I can't even get irw to spit out keycodes. Has anyone been in a similar situation? - What should I configure the Harmony device as? A generic MCE remote? The reciever in question? - How do I configure the reciever in lirc? Generic devinput? A specific reciever? And this is before I then get to trying to match up keycodes in XBMC to get it all talking properly. Any advice? cheers, / Brett
