experience with XFS
by Anthony Shipman 07 Apr '12

07 Apr '12

I've been running a Centos 6.2 system for two months now. I've been using XFS for the /home file system since I had the impression it would be better for large file systems by avoiding long fsck times. At the same time the nvidia driver has proved to be buggy and has crashed the system several times. XFS has the habit of zeroing out some files each time there is a crash. This would be understandable for files that were being written around the time of the crash. But I've had files be erased that were created hours before the crash and were read-only after creation. I've set some sysctl parameters down to 5 seconds to flush more frequenctly fs.xfs.xfssyncd_centisecs = 500 fs.xfs.xfsbufd_centisecs = 100 fs.xfs.age_buffer_centisecs = 500 fs.xfs.filestream_centisecs = 500 (The file system is mounted with options "defaults,relatime") You wouldn't expect files last modified more than 12 hours before the crash to be erased but that is what has just happened this Friday evening. Perhaps there is some care and feeding of XFS that I'm not doing? Should I be using xfs_repair? I expect I'll just switch to ext4. -- Anthony Shipman Mamas don't let your babies als(a)iinet.net.au grow up to be outsourced.

Hi Lindsay, I'm sorry you feel this way about luv-main, may I instead suggest reframing the question? Rather than take this elsewhere the way to make this on topic may instead be to ask how to investigate the attachment safely under Linux to ascertain whether or not it is malicious and, if not malicious, learn what it actually is. Please don't take the criticism to heart, it's not personal, but born of experience of lists that have gotten mired in off-topic discussions. All the best, Chris (on a phone so excuse formatting)

Coincedence or scam.........
by Lindsay Sprinter 06 Apr '12

06 Apr '12

On the 4th of april I had a packaged dipatched from the UK order number #112460. Yesterday I received an email, address was to my mcmedia email account stating shipment number 2633 had been returned to the the FedEx office, "the reason incorrect deliver address, please print out invoice copy attached and collect the package at our office." The atttachment is an exe not a pdf or doc file. I will not normally run anthing sent to me un announced. Every other case something like this has occured one gets either a pdf or a doc file. My strong suspicion is this is a scam and the timing is just a coincidence..........a develish coincedence. Would it be worthwhile to contact the suppliers of my package. I have recieved other items in the past no problems. Lindsay

While the post was security related, it wasn't Linux or LUV related, so luv-talk was the place to raise it. Actually, luv-talk has been fairly quiet of late, and when a discussion that you're not interested in flares up, it shouldn't be too difficult to filter the offending thread.

Re: mail storage in a distributed database

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

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. In my SpamAssassin configuration I have the above query which gives output like the following when run against my account: +----------------+---------------------------------------+ | preference | value | +----------------+---------------------------------------+ | blacklist_from | jenny(a)videonow.com | | whitelist_from | russell(a)coker.com.au | [...] +----------------+---------------------------------------+ 115 rows in set (0.00 sec) Do the below errors indicate that SpamAssassin received a preference without a value? If so why might that happen? None of the accounts in question have a null value for the email column.

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.
