[14:20] <thafreak> what the hell...stupid selinux
[14:20] <thafreak> centos totally fsck'd my practical final exam
[14:21] <thafreak> i spent the whole time trying to figure out why ssh with keys to a centos vm wasn't working
[14:21] <thafreak> turned out to be selinux related
[14:21] <thafreak> i guess ssh-copy-id from ubuntu to centos didn't set the appropriate context on the authorized keys file
[14:22] <thafreak> luckily, i gave them 2 classes to do the exam...and it's mostly automated by scripts
[14:22] <thafreak> but still
[14:22] <thafreak> stupid selinux
[15:26]  * _bbb_ shakes fist at selinux
[15:27] <_bbb_> setenforce 0 ftw
[15:50]  * thafreak always feels bad just turning it off...
[15:50] <thafreak> like saying, this condom sucks, and throw it away mid coitis
[15:51] <andygraybeal> thafreak, discretely though, of course :)
[15:51] <thafreak> totally asking for herpes...or getting back door'd...
[15:51] <thafreak> wait...i think i'm off topic
[15:52] <thafreak> or am i...
[15:52] <andygraybeal> hah
[15:56] <_bbb_> so apparantly
[15:56] <_bbb_> i have genital herpes
[15:57] <andygraybeal> that's okay, everyone else does too.
[15:57] <andygraybeal> just don't tell anyone.
[15:59] <thafreak> server herpes...i think it's symplex qq
[16:00] <andygraybeal> so you guys know about puppet?
[16:00] <andygraybeal> i figure i should be using it... or even start learning about it.
[16:01] <andygraybeal> it's one of those things where, i think i'm a failure as a small sysadmin
[16:01] <andygraybeal> but some of me is like.. eff it.. for craps sake
[16:34] <thafreak> i played with puppet
[16:34] <thafreak> it's not bad
[16:35] <thafreak> never setup a puppet master though...just made single recipes
[16:36] <thafreak> i liked the puppet syntax better than chef
[16:37] <thafreak> depends on what you want to do i guess...so many tools with lots of overlap
[16:37] <thafreak> i also really like fabric
[16:37] <_bbb_> i like turtles
[16:38]  * canthus13 meant to go to a puppet presentation at ILF... 
[16:38] <canthus13> I fell asleep instead. :P
[16:38] <thafreak> sleep is for the weak
[16:38]  * thafreak looks at canthus13 
[16:40]  * canthus13 pokes at thafreak.
[16:40] <thafreak> ouch
[16:40]  * canthus13 was saving energy for the afterparty. :)
[16:40] <thafreak> i mean, pfft, that didn't hurt
[16:40] <thafreak> oic
[16:40] <thafreak> who was there? any entertainment...or just booze?
[16:42] <canthus13> Just booze... and a hovercopter thing.
[16:43] <canthus13> the main entertainment was the hackerspace with lockpicking competitions.
[16:45] <thafreak> and...you pick any locks
[16:45] <canthus13> Yep. :)
[16:47] <thafreak> you win anything?
[16:47] <canthus13> Nope.
[16:47]  * canthus13 can handle simple padlocks but that's about it.
[18:27] <andygraybeal> ah up in cleveland?
[18:28] <andygraybeal> thafreak, bro, thanks for the response on puppet :)
[18:28] <thafreak> np
[18:28] <thafreak> if you can stand ruby code, chef seems to be more popular
[18:29] <thafreak> if you can't stand to look at ruby...puppet seems easier to swallow...
[18:29] <thafreak> and if you start with just a single puppet manifest file, it's actually not too hard to jump in
[18:30] <thafreak> or, if you like python, fabric is cool...basically write code that gets run over an ssh connection to a remote machine
[18:30] <thafreak> or :)
[18:30] <thafreak> you can use fabric to put puppet manifests on remote machine and then run it
[18:32] <thafreak> but anyway...for whatever reason the hotness for the "agile" "devops" type sysadmins seems to be chef
[18:35] <thafreak> Anyone try 12.04 lately? server or xfce? (i'll avoid asking about unity, as that's justa can of worms)
[18:35] <thafreak> or lubuntu
[18:37] <toddc> installing 12.04 server tomorrow night on two machines and have 12.04 unity on 4 machines now so far so good they fixed a lot of the unity bugs
[18:37] <thafreak> cool
[18:38] <canthus13> toddc: they got rid of unity?
[18:39] <thafreak> YAY!! they updated the qemu-kvm to support librados...sweet
[18:39] <thafreak> i was worried for a while it wouldn't make it in
[18:39] <thafreak> FYI, raddos is neat...
[18:39] <toddc> well there is a gnome 2 option but I have been using unity for a while and got used to it
[18:40]  * thafreak tries to change subject off unity
[18:40] <andygraybeal> thafreak, damn bro, that is some crazy information
[18:40] <andygraybeal> thafreak, what is librados?  i love kvm
[18:40] <andygraybeal> goddamn i gotta google this s hit
[18:40] <thafreak> i wasted...erm spent, a number of hours...erm weeks...trying to figure out which one i'd like to use best
[18:41] <thafreak> so, you hear of ceph?
[18:41] <andygraybeal> never
[18:41] <thafreak> ceph is a distributed filesystem in the main line kernel
[18:41] <andygraybeal> oh awesome
[18:41] <andygraybeal> like andrew
[18:42] <thafreak> how it works, is it uses object stores, that store dumb blobs of data
[18:42] <andygraybeal> AFS
[18:42] <thafreak> i dunno the underlying nature of AFS...but from the user point of view, they're probably similar
[18:43] <thafreak> well, ceph isn't really ready for prime time yet...BUT, the dumb blob storage part is there
[18:43] <thafreak> one thing they built ontop of it is RBD images...which are like NBD (network block devices)
[18:44] <thafreak> but the RBD is broken up into chunks, and striped across your cluster of dumb blob storage machines
[18:45] <thafreak> so, you can give a VM a disk device that is an RBD drive, and it's data is striped across a bunch of storage nodes for speed/redundancy
[18:46] <thafreak> at work, we have 4 kvm nodes, and right now, they use a central  NAS for storing disk images...well, I can't reboot the NAS now, not without taking EVERYTHING down
[18:46] <thafreak> so i've been scouring the net looking for a more distributed solution, and these rbd images seem like they might be the ticket
[18:47] <andygraybeal> where do you keep up with this information?
[18:47] <andygraybeal> is there a magazine i should be reading?
[18:47] <thafreak> so I'm excited 12.04's kvm has support for rbd...finally something for me to be excited about for 12.04 :)
[18:47] <thafreak> uh...nope...i spend LOTS of time on google honestly
[18:48] <andygraybeal> wow this is great
[18:48] <thafreak> probably 1/3 to 1/2 my day realistically
[18:48] <thafreak> very little time to actually work on anything :)
[18:48] <andygraybeal> yea, RnD :)
[18:51] <andygraybeal> so what kind of network infrastructure would be internal to that file system?  would it have to be fiber?
[18:53] <thafreak> no
[18:53] <thafreak> but most of the people seriously building distributed file systems are always talking about 10gig-e
[18:53] <andygraybeal> so gigabit copper is fine
[18:53] <andygraybeal> ah ok
[18:54] <andygraybeal> shit :)
[18:54] <thafreak> yeah, for most normal people, gigabit is still faster than most disk drives
[18:54] <canthus13> gigabit is faster than most drive interfaces. :P
[18:54] <andygraybeal> and would there be a redundant switch(es) between this?
[18:55] <thafreak> could be i suppose
[18:55] <andygraybeal> i guess, which is the next step in total redundancy?
[18:55] <thafreak> not sure how multipathing would work like that though
[18:56] <thafreak> i don't know if there is  such a thing...there's always trade offs
[18:56] <thafreak> true redundancy, you'd need multiple geographically separate locations...
[18:56] <thafreak> and sync'ing between them usually makes things slow...
[18:57] <thafreak> distributed filesystems like this are more meant to scale up in size and speed more than be really redundant
[18:57] <andygraybeal> aaah.. i see.. i was headed in the wrong direction
[18:57] <thafreak> making it possible to store petabyte size stuff
[18:58] <andygraybeal> so... do you back up this monstrosity?  or is it it's own backup.. you hope atleast?
[18:58] <thafreak> now maybe you could hook something like async drbd to your rbd image and sync it to a remote location too...
[18:58] <andygraybeal> is the filesytem taking snapshots like zfs?
[18:58] <thafreak> for me, i'm going to make the central NAS be the backup
[18:59] <thafreak> well, the storage nodes that store objects, they use an underlying file system
[18:59] <thafreak> and they recommend btrfs currently
[18:59] <thafreak> but ext4 would work too
[18:59] <andygraybeal> yea, btrfs last time i looked wasn't ready for anything
[18:59] <thafreak> not sure where you would do snapshotting at...
[19:00] <thafreak> it works pretty good in some situations...hopefully it will be ready soonish
[19:00] <andygraybeal> yea, what your talking about is way over my head :)  it makes me excited though
[19:00] <thafreak> me too...
[19:01] <thafreak> there's also something called sheepdog, fyi, if you have more than one kvm server
[19:01] <andygraybeal> i'm still stuck in user application land.. not so much infrastructure at this point.
[19:01] <thafreak> i haven't dug into that too deeply though
[19:01] <andygraybeal> i have two kvm servers
[19:01] <andygraybeal> i will look it up
[19:02] <thafreak> i guess it's not uber fast, but more focused on reliable replication of block devices between nodes...
[19:02] <thafreak> so you can live migrate between any of your N nodes
[19:02] <andygraybeal> wow nice
[19:03] <thafreak> i'll hopefully check it out and this rbd stuff soon
[19:03] <andygraybeal> that stuff is very exciting.  i might wait a bit till it becomes polished a little, i hope that doesn't make you hate me :
[19:03] <thafreak> see which works best
[19:03] <thafreak> nah
[19:03] <thafreak> i trust the LTS stuff
[19:03] <thafreak> so if it's in there, i'll use it
[19:03] <thafreak> if I have to build things from source...i tend to avoid it sadly
[19:03] <thafreak> so i understand
[19:04] <andygraybeal> 8.04 was a bit of a kvm pain :)
[19:04] <thafreak> the rbd stuff is in this LTS...and i think sheepdog is too...so i'm assuming they felt it polished enough
[19:04] <andygraybeal> awesome, i will try it then
[19:04] <thafreak> i used xen still on 8.04
[19:05] <thafreak> actually, I still have one 8.04 xen box running....need to migrate the vm's off
[19:05] <andygraybeal> yea, it wasnb't really that long ago
[19:05] <thafreak> i wish i had more machines to test on
[19:30] <Unit193> skellat: Your podcast was in the Ubuntu Weekly News.
[19:32] <skellat> :-)
[20:00] <Unit193> Cheri703: You happen to see something like this http://www.webupd8.org/2012/04/valvle-works-on-steam-for-linux.html ?
[20:02] <canthus13> Unit193: Funny.
[20:02] <Unit193> canthus13: I don't care, but what's-his-name might.
[20:41] <thafreak> i've used steam in wine...but i would probably do alot more pc gaming if they actually did port steam to linux
[21:42] <BiosElement2> I'm alive >.>
[21:42] <Unit193> This is news? ;0
[21:42] <Unit193> Welcome back.
[21:42] <BiosElement2> It should be ;P
[23:21] <canthus13> Visig0th: That's a rather lame visigoth raid. :/
[23:23] <Visig0th> Sorry, was having client issues..
[23:25] <Visig0th> I shoud've known better than trying to experiment with xchat again after being away from it for so long and having been used to irssi.
[23:25] <Visig0th> Its fixed now, so no more jumping in and out.
[23:26] <Visig0th> And of course hello, btw. I'm Bradley. I generally go by simply Visigoth, that is without the "0". I'm in SW Ohio.
