Re: [SLUG] Wireless Broadband?
Part of the motivation for buying a modem out-right and use pre-paid is that it doesn't tie us to any plan, plus we expect to use the pre-paid modem very sporadically - in emergencies which happen when the guy on call is out and just must access the network. the down side of pre-paid is that the data expires fairly quickly. a few gigs typically only has a 30 day expiry. larger data blocks tend to last longer (up to 90 days on optus) you can just whip out your credit card and buy a data block. that may not sit well with the on call person...

Can anyone here have positive experience with this moddem? No, I can not. :) You're better off buying their network gateway for $399, which is the BigPond "Elite" network gateway on this page: http://www.bigpond.com/internet/plans/wireless/wireless_devices/ It works flawlessly, and since it has an internal wifi gateway and 4 port switch it doesn't require any configuration with Linux. I use mine on the boat with a 12v lead in from the house batteries but I've also run it while travelling off a 12v plug pack powered by a 7Ah sealed battery of a reasonably common type (Jaycar will have them). Bigpond are the biggest wunch(*) on the planet, so you have to be aware. One issue is that although all of their devices are essentially compatible, your internet plan is tied to the device so if you get one of their plug in modems and decide later you want the gateway, you have to cancel (and pay out) your old plan and buy a new plan. No other internet provider makes you do this -- e.g. iinet don't make you cancel your plan if you buy a new ADSL modem.

Thanks for the warning but unless Telstra completely redefined the meaning of "pre-paid" I shouldn't be concerned about over-charges - as soon as I run out of credit the connection should drop, end of story. Or should I? The modem is meant to be rotated between people on call which might need it to get away from their home computer while on duty. Luckily all our ops guys have Ubuntu on their laptops so it limits the search for support. The virgin (post-paid) deal is not a drop dead but a shaped response (ie slow down of bandwidth) once you meet your monthly limit (5G, which I haven't yet). I have heard horror stories from people on post-paid - not to mention living a life of fear. The worst one was Telstra, where I think the download limit was met once you viewed the Telstra homepage a couple of timesand that was the default homepage for their browser. With regard to the pre-paid you still get stung as you are paying a premium rate for what you do downloadthough this looks like a reasonable deal...for the infrequent user... BTW the 3 prepaid is a very good deal - $149 for 12GB and 12 months to use it. If you don't use it in 12 months, you can rollover the balance. I'm mobile between the CBD, western suburbs, south western suburbs and southern suburbs and the coverage is pretty good. Also the network is not as congested as, say, Optus which can be unusable during normal online time. but maybe the 12GB will be gone in 3 months and you are really looking at $600 a year compared to 12x40=$480/year capped shaped from Virgin (and I think Optus directly now also).

The code was written to deal with uploads and parse them / process them / stick bits into the database. As time goes by the uploads grow from kb to Mb and change from simple format to vast swathes of @#...@^ xml. The same job which used to take less than a few seconds now causes timeouts in apache which we've had to raise and/or the browser. Which we can't do much about. This is all in java so it's not too difficult to make it asynch wrt to the original http request. And leave the use perhaps with an ajaxy update page. I know next to nothing about PHP, but can't you spawn another thread unrelated to a client http request? Then you can finish this page, redirect them to another page which just waits for the result to come back - checking now and then via the db or some file on disk.

[SLUG] Push cron and system E-Mails to RSS (email2rss?)
Hello, I'm interested to hear how system administrators handle the plethora of E-Mails servers tend to generate. Especially ones with various cron jobs. Is the typically practice to add .forwards and consume the reports with the rest of your E-Mail? How about an pushing them to a RSS feed which isn't as intrusive ?

Hi Alan, You can find what package provides the ldd program, and then verify the integrity of the package. If it really changed I think you should look for any suspicious activity in your server. I think you can find the package with dpkg -S $(which ldd) and you can check its integrity with debsum. ldd shouldn't change, unless you have updated your system.

[SLUG] SLUG Janurary Monthly Meeting
You can read the full version of this announcement at http://slug.org.au/node/122 == Summary == Date: Friday 29nd of January (Friday next week). Start Time: Arrive at 6:15pm for a 6:30pm start Format: Lightning Talks, BOFs, Pizza Dinner Where: Google Australia, opposite Star City == SLUG January Monthly Meeting == Instead of running two 45 minute talks will be having two sets of Lightning talks. For those who don't know what a Lightning talk is, it's a very short talk to get a short overview about a subject. They are great because if you are not interested in the current subject you only have to listen for 5 minutes. I personally have found that I always learn something cool, exciting or new! The first section will be on "General Lightning talks", each person will get 5 minutes (and 5 minutes only) to talk about anything from something simple as "The new idea I want help with" to the "My summary of this 45 minute talk" or even "5 cool facts about Rusty Russell". The second section will be on "In-depth Lightning Talks", each person will get 7 minutes to talk about something a bit more indepth. *Slots are still available*, so if you are interested in talking, please sign up at the following URL: https://spreadsheets.google.com/ccc?key=t6Is2nMnHr3Q-Xt7cOAHpkQ&hl=en = Meeting Details = SLUG is the very mis-named Sydney Linux User Group. We are a general Open Source interest group which runs our primary event on the last Friday of every month (except December). Meetings are open to the general public, and are free of charge. Our venue is Google, Level 5, 48 Pirrama Road, Pyrmont. It's across the road from Star City Casino. A map of the area can be found here[1], and public transit directions are at [2]. Appropriate signage and directions will be posted around the building. You will need to sign-in to enter the venue. This can be performed when you arrive, but to save time we recommend that you do so online beforehand at Eventbrite[3]. If you are unsure, please sign up as a 'maybe'. This allows us to organise adequate meeting space and facilities. You do not need to create an account to indicate your attendance. = Meeting Schedule = We start at 18.30 but we ask that people arrive at least 15 minutes early so we an all get into the building and start on time. Please do not arrive before 18.00, as it may hinder business activities for our host! See here[5] for an explanation of the segments. * 18.15: Open Doors * 18.30: Announcements, News, Introductions * 18.45: General Talk * 19.30: Intermission * 19.45: In-Depth Talk * 20.30: Dinner BoFs and the Hackerspace run from the time the doors open. = Bird of a Feather (BoF) Sessions = The list of BoFs at the moment are: * SLUGlets - our regular forum for newbies and desktop users If you would like to run a BoF, please discuss on the SLUG Activities mailing list[4]. = Hacker Space = We have heaps of room available to us at Google. If the talks do not grab you, feel free to come along and hack away on your favourite project in the designated Hacker Space. = Dinner = For dinner, we order in a selection of pizzas. The cost is $10 per head, and we will be collecting money from the beginning of the meeting. If you have any particular dietary requirements (e.g. vegetarian), let us know beforehand. Dinner is a great way to socialise and learn in a relaxed atmosphere :) For those who want to continue the conversation after dinner, some of us will be heading to a pub in the local area.

Re: [SLUG] Wireless Broadband?
A variety of responses. I would like to ask - why have a tricky device-dependant USB driver at all? The Optus Huwei, Bigpond whatever-it-is hub or a 3rd party device like an Ericsson W25/W35 is a network device. Sure it's not so handy since it requires a power supply and it's a bit lumpier for cruising the M4, but if you had a back-seat passenger wanting internet access too you would go for it. I used to have to keep a remote site Bigpond Asiasat modem going, that had a USB interface. It was a frabjous day when Telstra replaced it with a new modem with ethernet. There was just a single Windows machine hanging off it, causing all sorts of driver heartache. Now it runs through a wireless hub with several people using it trouble-free. In my book USB is in the same camp as Bluetooth as a 'solution' to avoid. Kevin.

Re: [SLUG] Wireless Broadband?
I have a laptop with a Sierra Wireless modem built-in. Stuffed if I can get the sodding thing to work on Ubuntu Karmic. The SIM (3 prepaid) works fine with other modem dongles on Ubuntu and also works with the PC modem on Windoze. I guess the moral is - check before you buy :) BTW the 3 prepaid is a very good deal - $149 for 12GB and 12 months to use it. If you don't use it in 12 months, you can rollover the balance.

Thanks for the warning but unless Telstra completely redefined the meaning of "pre-paid" I shouldn't be concerned about over-charges - as soon as I run out of credit the connection should drop, end of story. Or should I? The modem is meant to be rotated between people on call which might need it to get away from their home computer while on duty. Luckily all our ops guys have Ubuntu on their laptops so it limits the search for support.

I said it might take a few seconds, I didn't say it was computationally heavy. justin randell wrote: hi, 2010/1/21 Peter Rundle : It's alleged Ken Foskey did scribe: You could try closing STDOUT which will tell apache that your script has stopped output.

Re: [SLUG] Copying HDD
Simply create a new partition and copy the contents. Use cp -r / path /mounted/new/path/ If you have to use dd then create a partition exactly the same size then gparted can grow it afterwards Ken Foskey On the move On 20/01/2010, at 2:00 PM, Mike Andy wrote: I've been thus far unable to do to - maybe you can explain how. for example, if i do a dd from a 120Gb to a 150Gb and then enter into something like gparted or fdisk there seems to be no way i can simply expand the disk beyond the original 120Gb boundaries. If there was unformatted/unpartitioned space within that 120Gb then things can be moved around there but not outside the original disk boundaries.
