mnathani_brycec: how is your ARP Metal box coming along
?
[13:14]
brycecGreat, I'd say.
No issues, runs fast, etc
[13:14]
mnathani_my main concern with the Metal series is no redunand storage out of the box
s/redunand/redundant
[13:16]
BryceBot<mnathani_> my main concern with the Metal series is no redundant storage out of the box [13:16]
mnathani_which make a vps way more reliable [13:16]
brycecyeah, a reasonable concern, but that's only for 2 of the "tiers"
https://www.arpnetworks.com/dedicated $129 and $149 options are single-drive
(and fwiw, I sent up_the_irons an email this morning asking about upgradeabilty)
[13:16]
mnathani_the 2 hard drive options $169 and $189 still no Hardware RAID [13:18]
brycecbrycec is almost always happier with software-based raid
(Cheaper, more flexible, just as fast, not tied to a specific controller, etc)
[13:18]
mnathani_I know Linux works well with software RAID, but I dont think Windows and VMware support it [13:20]
brycecheh, I'm *nix-only so my experience is mdadm, softraid(), ZFS, etc
And in those instances, it's great.
I don't have a clue how to setup software raid in windows...
(or if it's even possible)
(I wouldn't be surprised if it weren't)
(I think OSX can do soft-raid for non-boot disks.)
[13:21]
mnathani_I think you can make a RAID volume, just cant boot off it
in Windows
[13:22]
............. (idle for 1h3mn)
mercutiomnathani_: run windows as a vm on linux? :)
esxi doesn't have raid support
it's kind of lame
so you need something that does external raid
but some people run that something else as a freebsd/opensolaris/linux host with zfs
and export the data store for virtual machines from the virtual machine
[14:25]
twobithackerthat vaguely sounds like a recipe for disaster [14:28]
mercutiousing esxi?
lots of people do it
i'm not sure how the base vm's storage is allocated.
like i'd want to do vt-d and pass through the sata controller
[14:29]
twobithackernah, using a vm to do the storage for other vms. It should be fine, so long as you don't create any circular dependancies of that storage VM on other VMs that have their storage on it (like LDAP auth or something) [14:30]
mercutioyeah well i'd ratehr a second server myself :/
damnit now i'm curious what esxi's openbsd performance is like
someone in the zol channel was tellign me about this iscsi thing they were doing that made it easy to change what a computer booted
but even just reimaging quickly would be nice :)
[14:30]
brycecOpenBSD on ESXi is quite reasonable. Can't say as I've done a ton of performance testing, but it seems to respond as fast as bare metal would. [14:33]
***hoggworm_ has joined #arpnetworks [14:37]
mercutiobrycec: oh i got lousy performance last time i tried it..
oh openbsd doesn't support kvm virtio drivers does it?
oops
esxi doesn't.
[14:37]
brycecYep, it does
I'm using vmxnet3 and virtio for disk
[14:38]
mercutioi was thinking there may be virtio on esxi now
erk i meant on esxi
[14:38]
***hoggworm has quit IRC (Write error: Broken pipe) [14:39]
brycec"SCSI Controller Type: Paravirtual" close enough :p [14:39]
mercutiooh interesting [14:39]
brycec(And as I said, vmxnet3 for network) [14:40]
mercutiooh right
cool i should try it
i was struggling to get more than 3 gigabit/sec from guest-to-host with kvm
and even just gigabit was a struggle
err to host i mean host node
to another host it was using heaps of cpu just doing gigabit
[14:40]
brycecheh [14:41]
mercutiomy 10gbe cards came though [14:41]
brycecWell I can't promise or guarantee anything :p Only that it works well enough for my uses. [14:41]
mercutioyeah i'm just curious about the openbsd network bottlenecks.
i want to try porting the freebsd 10gbe driver to openbsd.
[14:42]
brycecSupposedly vmxnet3 is supposed to be the bee's knees, or at least the best vmware can come up with. Identifies as a 10GbE link [14:43]
mercutioyeh i think part of the issue is openbsd not really supporting many offload features in general.
like on any drivers

brycecty up_the_irons
(but can I add a 3rd? a 4th?)
brycec reads up_the_irons' email reply
Dual E5-2630? Shiny... (especially considering the blade size)
up_the_irons: btw, don't forget the comma (thumb) m/,
[18:25]
mercutiodual e5-2630 is overkill for most people
you need heavily threading to really benefit
[18:29]
brycec(he mentioned he has a couple of systems build with those, a mere $499)
*built
[18:30]
mercutioon "light" load it's no better than an e3
yeah if you haev high load it would be nice :)
even dual quad core+ht is hard to use
i'm pretty sure e5-2630 is hex core
there's also numa complications...
memory and pci-e devices are owned by the cpu
so it's not straight twice as fast as single cpu

mnathani_Anyone know of a service that can host a contact form on their site, where I can include it on my site and when someone fills it out their hosted site can send me an email ?
a quick search found: http://blog.templatemonster.com/2010/07/08/free-contact-form-services/
but not sure which ones are hosted and send me emails directly
[19:02]
mercutioyou could just use something like formmail?
it's not hosted though
looks like googling such may help you find a hosted service though
[19:09]
mnathani_There are many results
was hoping for someone to refer me to a service they might have tried
[19:14]
mercutioahh ok
someone still might :)
[19:15]
brycecDoesn't Google Docs' Forms do that?
mnathani_: ^
I've used it in similar ways, and I know I've been the end-user of it too.
With the added bonus that it gets stored right in a spreadsheet.
http://www.google.com/forms/about/
It certainly will serve as a contact form. Only a question of how "embeddable" it is.
[19:19]
mnathani_I tried an embedded google form
it works great in that it puts the result in a spreadsheet
but $client would prefer an email for each form submission
[19:23]
brycec(Oh good, they do allow embedding) [19:25]
mnathani_2 ways I know: iframe, and another method where you copy and paste the sourcecode
into your page
[19:25]
brycecmnathani_: You should be able to setup notifications on the spreadsheet to email on any change.
s/should be able/can/
[19:26]
BryceBot<brycec> mnathani_: You can to setup notifications on the spreadsheet to email on any change. [19:26]
brycec(meh, close enough. English hard is.) [19:26]
up_the_ironsbrycec: you can do 3 and 4 but requires a 1U chassis, so we'd have to migrate you if you wanted that
brycec: the E5's are 1Us, not blades
[19:32]
brycecAh, good to know. Thanks for the clarity, up_the_irons :D [19:32]
up_the_ironsbrycec: ah, i never saw it with the comma (thumb) before ;)
np!
[19:32]
bryceclol [19:32]
up_the_ironsup_the_irons leaves the office [19:32]
brycecbrycec remains in the office... because he works from home. [19:33]
mnathani_I enabled spreadsheet notification, but it doesnt seem to notify consistently, and even when it does, it links to the spreadsheet rather than present the contact form submission contents itself [19:33]
brycechm, bummer. mnathani_: That just leaves writing some Google Script :D (well I'm sure someone else already has written that exact function)
eg under Forms' "Add-ons" menu, there is one named "Form Notifications"
(And the published source, because I can't link to the Add-on itself https://github.com/googlesamples/apps-script-form-notifications-addon(
[19:34]
mnathani_checking out the addon
hadn't seen that before
thanks brycec

mercutiomnathani_: i'd check if bird has a packaeg available ratehr thqn auagga
https://github.com/openwrt-routing/packages
that looks like it has some extra stuff
but bird is probably in normal repo too
http://blog.philippklaus.de/2012/12/dynamic-routing-with-bird-running-the-ipv6-based-ospfv3-protocol-on-openwrt/
[22:28]
mnathani_I would imagine you need a pretty beefy router to support bird /quagga [22:31]
mercutioif you want a full route table yeah
but most routers have 128mb of ram
[22:31]
mnathani_not running bgp [22:32]
mercutioif you want 100k routes you'd probably be fine. [22:32]
mnathani_just basic internal ospf [22:32]
mercutiobird does ospf too
you could prboably do a full ipv6 table fine
"at the moment"
well there's choice between bird/quagga
and quagga is really buggy
that said it may be better now
both should be available.
