[04:09] <Symmetria> morning
[04:36] <kulelu88> yo Symmetria 
[08:24] <magespawn> good morning
[08:43] <gremble> Good morning
[08:50] <magespawn> hi gremble 
[11:14] <Symmetria> mmmm
[11:14] <Symmetria> iscsi chews cpu at high speed :(
[13:12] <gremble> Chew ir back Symmetria 
[13:12] <gremble> it* even
[13:12] <gremble> How are you magespawn?
[13:30] <magespawn> hey gremble
[13:31] <magespawn> good thanks, a bit cold for thie part of the world but thatis nice
[13:55] <gremble> It looks like it may rain. I just hope it hurries up and rains
[14:05] <magespawn> we have had a little rain here lately
[15:40] <magespawn> i am having a bit of a problem with ssh into a server i keep getting: Permission denied (publickey)
[15:47] <magespawn> i am pretty sure it is something simple
[16:10] <magespawn> cool beans got it sorted
[16:40] <inetpro> good evenings
[16:41] <Kilos> hi all, sorry for being missing, been very busy
[16:43] <gremble> What was the problem magespawn?
[16:44] <gremble> Sounds like a wrong passphrase for the public key (That's when I got that error)
[16:46] <magespawn> wrong public key
[16:46] <magespawn> i think
[16:46] <magespawn> hi Kilos 
[16:54] <Kilos> hi magespawn gremble 
[16:54] <Kilos> and others
[16:55] <gremble> How are you Kilos?
[16:55] <gremble> Are you well? All your ailments better?
[16:56] <Kilos> still same ty only been busy trying to sort drives for ian and once again wiping my drive with the zero command
[16:56] <gremble> Why did you wipe your drive?
[16:56] <Kilos> at least it killed the guide stuff on his drive as well
[16:56] <Kilos> by accident
[16:56] <gremble> Hahahaha
[16:56] <gremble> Sorry :<
[16:57] <Kilos> dd command wiped both drives
[16:57] <Kilos> ty
[16:57] <Kilos> i must remember to only use it from live cd
[16:57] <gremble> That is why dd is also known as drive destroyer
[16:57] <Kilos> ya
[16:57] <Kilos> whew everything gone
[16:57] <gremble> Must just be careful how you use the command, just like rm
[16:58] <Kilos> luckily i was slowly bringing stuff to lappy
[16:58] <Kilos> otherwise i wouldnt even be here now
[17:00] <Kilos> now im hoping i saved isos somewhere else
[17:00] <magespawn> i have always been very wary of running that command
[17:00] <Kilos> lol
[17:01] <Kilos> kills the guid thing though
[17:01] <gremble> :P Just go `dd if=/dev/urand of=/dev/*` :P
[17:01] <Kilos> so from live cd should be safe as long as only one drive plugged in
[17:01] <gremble> burn everything
[17:02] <gremble> I don't have urand, so just make that /dev/random :P
[17:03] <Kilos> sjoe
[17:03] <Kilos> now i bang that command
[17:03] <magespawn> gremble: no /dev/null
[17:03] <Kilos> second time i wiped drive
[17:03] <magespawn> s/no/not
[17:04] <gremble> magespawn: you can't write out from /dev/null 
[17:04] <magespawn> ahh true
[17:04] <gremble> it just gives you end-of-file 
[17:04] <magespawn> nothing there
[17:04] <gremble> Sysadmin got served
[17:04] <gremble> :P
[17:06] <magespawn> ?
[17:09] <magespawn> who? me?
[17:13] <Kilos> hopefully will be back. need modem for destop upgrade
[17:13] <Kilos> be good
[17:21] <inetpro> wb oom Kilos 
[17:21] <Kilos> ty and hi inetpro 
[17:23] <gremble> No I have no idea
[17:23] <gremble> I just felt like saying that
[17:23] <gremble> :P
[17:23] <gremble> Hey inetpro 
[17:29] <magespawn> i see
[18:00] <smile|hetregent> tot later :p = see ya :p
[18:26] <gremble> No one wants a mathematician
[18:26] <gremble> :<
[18:27] <gremble> SANAE wants either an electronic engineer or a physicist
[18:40] <magespawn> gremble what would a mathematician do ?
[18:40] <gremble> Like, I can count things for them. 
[18:40] <gremble> Haha
[18:40] <gremble> Find roots of stuff
[18:40] <gremble> and such
[18:41] <gremble> Explain knot theory while we all sit huddled together in the cold dark antarctic winter
[18:41] <magespawn> okay then
[18:42] <gremble> I'm assuming that you don't agree 
[18:42] <magespawn> not at all, just have no idea what knot theory is
[18:42] <gremble> It is literally the math behind untying knots
[18:43] <magespawn> now that is pretty cool
[18:44] <magespawn> somebody had a lot of time on their hands at some point
[18:45] <gremble> Somebody got a Ph.D for that 
[18:45] <gremble> :P
[18:46] <magespawn> so somebody really had a lot of time on their hands
[18:46] <magespawn> knots too
[18:47] <gremble> Yup. And an interesting application for knot theory is the untying of DNA
[18:47] <magespawn> trefoil knot looks a little like a triquetra
[18:48] <magespawn> untying dna?
[18:48] <magespawn> alright then
[18:48] <gremble> http://www.tiem.utk.edu/~gross/bioed/webmodules/DNAknot.html
[18:49] <gremble> The first paragraph is the interesting bit
[18:49] <gremble> Unless you're keen on knot theory
[18:49] <gremble> :P
[18:52] <magespawn> always good to have a read on something completely new
[18:53] <gremble> This is why I love what I study. There are so many clever people doing really interesting work. 
[18:56] <magespawn> and jobs?
[18:58] <gremble> Eh. I'd preferrably go into academia. But if I had to look for a job right now, I'd probably try for the publication industry. Working at the newspaper has been so much fun
[18:58] <gremble> But I can do applied mathematics and probably programming
[19:01] <magespawn> gremble: why would the newspaper need a mathematician?
[19:02] <gremble> They don't
[19:02] <gremble> They need a subeditor
[19:02] <gremble> which is what I do
[19:02] <gremble> among other things
[19:02] <gremble> Haha. I can do layout, I've written for them and I've drawn some cartoons
[19:02] <magespawn> okay you had me confused there for a second
[19:04] <gremble> Certainly confuses my family haha
[19:04] <gremble> "what are you studying?" "BSc mathematics." "What job will you do when you're done?" "I'm thinking of working for a newspaper."
[19:04] <magespawn> i can't see why, it is a very logical grouping of jobs
[19:09] <gremble> Sup fulelu88
[19:10] <magespawn> i want to be able to monitor multiple adsl lines for uptime from the internet, and have the program report to me when they either go down or are not performing properly. any idea?
[19:11] <gremble> I know you can do that with mweb, but it would be really hacking and require scraping. Would it not be easier to get a router that you can modify the software of and have the router report when the DSL goes doen?
[19:11] <gremble> Since it has that hook already
[19:12] <magespawn> how would the router report when the dsl is down?
[19:13] <magespawn> i am not inside the network when they go down, if i am i notice right away most of the time
[19:14] <gremble> Hmm, I'm thinking of a homebased solution, so that is already probably not right. You could have a process that pings out, and reports if the ping drops or times out?
[19:14] <gremble> But if it cannot talk out, it wouldn't be able to report
[19:14] <gremble> So you'd want something to ping in
[19:15] <magespawn> yes
[19:15] <magespawn> and if possible measure speed as well
[19:15] <magespawn> and hopefully keep a log
[19:16] <magespawn> of course this also assumes some other things too
[19:17] <magespawn> like the connection between ping and the adsl never goes down
[19:18] <gremble> If I were a programmer, I would say you have two programs, one on one side of the router, and one on the other. The one outside sends a packet in with a specified TTL, the one inside catches it and sends it back with the TTL+(some constant) then you can read the difference to get an average of up and down speed
[19:19] <gremble> But yes, it does assume that the network beyond the internet doesn't go down
[19:20] <magespawn> and of course all this traffic will use data and bandwidth, not much maybe, but there we go
[19:21] <gremble> Not that much. You literally just want the packet header. I think it's 8 or 16 bits
[19:21] <magespawn> would not make any difference really to the end users
[19:22] <magespawn> now just to find such a program
[19:23] <magespawn> could have cron run ping at a specific interval, send the result to a log file and send that to myself
[19:23] <magespawn> or perhaps have it send an error only if it does not get a reply
[19:24] <gremble> Or if the reply takes more than a specific amount of time
[19:24] <magespawn> i would need to work out what would be a realistic time
[19:30] <magespawn> i could also set up a ping from inside the network and have the external server log those ping and send me an alert when a specified period of time has passed without a ping being recieved from a specific source
[19:30] <magespawn> that way i could log it from both sides
[19:31] <magespawn> also the external server would by its position of being online have a public ip address
[19:32] <magespawn> now to figure out how
[19:39] <magespawn> i have found a couple of services that can be used monitor.us and uptimerobot.com
[19:42] <superfly> *yawn*
[19:45] <magespawn> hey superfly
[19:46] <superfly> hi magespawn
[19:47] <kulelu88> gremble: fulelu?
[19:47] <kulelu88> yo gremble , superfly magespawn 
[19:47] <magespawn> hi kulelu88 
[19:49] <superfly> hi hi
[19:49] <gremble> I was being funny
[19:49] <gremble> :P
[19:49] <gremble> Hey kulelu88 
[19:49] <gremble> Hey superfly 
[19:50] <gremble> It's nice if there are already such services. If they aren't to expensive that is
[19:51] <magespawn> these ones offer their basic stuff for free
[19:52] <kulelu88> you guys listen to podcasts?
[19:53] <gremble> I haven't found ones that I like 
[19:53] <gremble> But I would like to listen to some
[19:53] <gremble> Especially on the commute to campus
[19:53] <gremble> Radio is starting to piss me off monumentally
[19:55] <kulelu88> what radio stations do you listen to?
[19:55] <superfly> I haven't listened to radio in years
[19:56] <gremble> I hate all of them. Tuks plays nice music, but the presenters are presenting themselves as idiots. ClassicFM has poor reception, and the others play music that irks me. I'm a grumpy man.
[19:57] <magespawn> all you need to do is add 'old' to that
[19:57] <gremble> I'm getting there
[19:57] <gremble> Give me a few years :P
[19:57] <kulelu88> i'm listening to a podcast about this guy speaking about the zar currency. not bad and valid points
[20:08] <superfly> I'm zonked, night all
[20:31] <magespawn> me too, good night all
[20:47] <inetpro> ai! 
[20:47] <inetpro> time gone without me saying much yet again 
[20:48] <inetpro> guess that is a good thing 
[20:49] <inetpro> good night 
[21:07] <kulelu88> wow, solid podcast
