DDNS Server [Scanned]
by Christopher M. Bailey 21 Nov '11

21 Nov '11

Hi All, I'm looking for a DDNS package that I can setup on a CentOS 5 server for potentially thousands of devices deployed at thousands of sites world wide. I have had a quick look at Bind9, which I think may buckle under this load if deployed by itself. I have also looked gnudip, but would like some feedback on how easy it is to setup and maintain, also any other packages people have used. TIA, Chris -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

With it's stellar line up, linux.conf.au 2012 should be on your horizon!
by Kathy Reid 19 Nov '11

19 Nov '11

Ballarat, 19 November 2011 With nine Miniconferences accepted, and three keynote speakers already announced, preparations are in full swing for linux.conf.au 2012, to be held in Ballarat, Victoria 16-20th January. Conference Director Josh Stewart was particularly pleased at progress to date. "We've got some huge names lined up to keynote, including Karen Sandler, Executive Director of the Gnome Foundation, Bruce Perens - the creator of the Open Source Definition, and the community's own favourite Mad Scientist Paul Fenwick. We still have one keynote up our sleeve, but it's a very closely guarded secret!". The conference schedule boasts a number of perennial favourites, including Jon Oxer, Andrew Tridgell of Samba, Valerie Aurora and Mary Gardiner of The Ada Initiative, Bdale Garbee and Jonathan Corbet. A number of new speakers are also on board for the first time, including software freedom advocate Ben Sturmfels. The number of accepted talks by female presenters was the highest on record, at just shy of 25%, speaking volumes about the ever-increasing diversity of the Linux and free and open source software community. Registrations for the conference are filling up fast. Early Bird registration for the conference sold out just before the early bird close of end of October. Stewart was enthusiastic at the response. "There was of course the usual rush just before Early Bird closed, and the whole team was sitting there with anticipation watching as we sold out! It's a great indication of the interest in the conference." For those interested in the conference, but for whom professional registration is out of reach, there are a number of alternative options, including Hobbyist and Student registration. Volunteer nominations are also welcome. Volunteers are given a free ticket to the conference in exchange for four days' volunteer work undertaking tasks such as audio visual, ushering and administration duties. * Registration pricing options: http://linux.conf.au/register/prices * Volunteer nomination: http://linux.conf.au/register/volunteer linux.conf.au will be held 16th-20th January 2012 in Ballarat, Victoria, Australia. http://lcaunderthestars.org.au and @linuxconfau on Twitter and Identica. Registrations are now open and a tentative schedule is at: http://linux.conf.au/programme/schedule <http://linux.conf.au/programme/schedule%22> Media enquiries are warmly welcomed to media(a)lcaunderthestars.org.au

don't run x on console
by James Harper 18 Nov '11

18 Nov '11

I'm testing zentyal in a xen VM (HVM) and everything I open on the console just crashes (opens/closes repeatedly). Apparently this is a known but with zentyal (openbox) but I don't really want a console X session anyway. Is there any easy way to turn it off? I think Ubuntu does things a little bit different to the debian that I'm used to. Thanks James

NNTP client recommendations
by Trent W. Buck 18 Nov '11

18 Nov '11

What is the newsreader equivalent of mutt? Rationale: I use NNTP for gwene, gmane and asr. I'm sick of Gnus. I'm not sick of NNTP -- (esp. not interested in RSS clients). Years ago, happily migrated mail from gnus to mutt. So, something like mutt for NNTP is what I want. PS: I notice mutt's debian/patches/ contains some NNTP patches that just need rebasing, maybe that's less icky than learning foorn...

bind configuration error
by James Harper 17 Nov '11

17 Nov '11

In light of the recent bind9 zero-day, I logged into my secondary ns to make sure there was nothing slipping passed the monitoring. There is no evidence of trouble, but I can see a heap of these messages: Nov 17 05:34:19 ns2 named[1088]: client 111.252.1.88#55544: query (cache) 'cluster8a.us.messagelabs.com/A/IN' denied Nov 17 05:35:21 ns2 named[1088]: client 95.89.214.87#3311: query (cache) 'cluster8a.us.messagelabs.com/A/IN' denied Nov 17 05:35:23 ns2 named[1088]: client 95.89.214.87#3345: query (cache) 'cluster8.us.messagelabs.com/A/IN' denied Nov 17 05:35:57 ns2 named[1088]: client 79.167.143.122#1148: query (cache) 'cluster8.us.messagelabs.com/A/IN' denied Nov 17 05:35:59 ns2 named[1088]: client 79.167.143.122#1175: query (cache) 'cluster8a.us.messagelabs.com/A/IN' denied Nov 17 05:37:13 ns2 named[1088]: client 190.213.41.176#2408: query (cache) 'cluster8.us.messagelabs.com/A/IN' denied Nov 17 05:37:15 ns2 named[1088]: client 190.213.41.176#2569: query (cache) 'cluster8a.us.messagelabs.com/A/IN' denied None of those IP addresses are ours, or our customers, but at least one zone on this server has MX records that point to the messagelabs.com addresses. Could I have configured something wrong that might be causing those IP addresses to try and resolve the messagelabs.com names via my server? Or could they be running a buggy resolver? Thanks James

Hmm, I'm using the gmail web interface. Do you see the same problem with email sent by other people using the gmail web interface? (wondering if it's a setting or lab setting I can play with).

Why is this a problem? This line has extra spaces in it to see if I can reproduce this issue myself, or if it just happens inside quotes.

Debian OEM mode install without preseeding ?
by Chris Samuel 16 Nov '11

16 Nov '11

Hi folks, I've got a couple of machines I want to give away and I'm hoping to do that with a PXE'd Debian install done using its OEM mode (in other words it'll ask them some questions from the recipient on first boot to set up their account). However, everything I can find about oem mode (which isn't a lot) talks about using the preseed file and as there's just 2 of these I was rather hoping that it would be a boot option to make it use OEM mode. If I do need to use OEM mode I've no idea how I'd do that with a PXE netboot'ed install.. Ideas ? cheers!
