up_the_ironsmhoran: have not worked with Juniper, except drool over them. IPv4 is routed by a Cisco 4500 w/ SUPIV [13:05]
mhoranup_the_irons: Ah, nifty.
Yeah, I'd like to work with a Juniper sometime.
We had one in the lab at Cisco but nobody knew how to use it and it wasn't hooked up.
[13:05]
up_the_ironshaha, Cisco had some Juniper gear in a closet, nice [13:06]
mhoranHeh. Yup.
Fuckign monit. What a shitty piece of software.
[13:08]
up_the_ironsoh certainly, monit is garbage
runit is the way to go
[13:08]
***cablehead has quit IRC ("Leaving.") [13:09]
mhoranInteresting. [13:09]
up_the_ironsrunit has one job -- to keep a process running [13:09]
mhoranHeh. [13:09]
up_the_ironsyou can trust it to do that [13:09]
***cablehead has joined #arpnetworks [13:09]
mhoranDoes it just do pid checks or can it do more advanced things like HTTP?
Our AOLservers like to die.
[13:09]
up_the_ironsmhoran: no, pid check is the way *not* to manage a process, because that's akin to "ps auxw | grep <PID>", subject to race conditions, etc... It manages a process because it is the parent of that process. Only in that way can you fully control a process [13:12]
mhoranNifty. [13:12]
up_the_ironsthen controlling the process is easy, like:
"sv stop my-proggy"
sv start
sv status
etc ...
[13:12]
mhoranAh, right.
If I dump monit, I still need a way to be alerted of service restarts, and to do those HTTP checks and reboots.
[13:13]
up_the_ironsand you can set groups that have access to individual supervisors, so there can be a group "web-admins" that can control *this* and "dns-admins" that can control *that* [13:14]
mhoranThat's nice. [13:14]
up_the_ironsmhoran: yeah, runit won't focus on those as much [13:14]
mhoranStill, looks pretty solid. [13:15]
up_the_ironsi run it (pun!!) on a lot of boxes, never was disappointed [13:15]
mhoranOf course, if runit dies, you're fucked.
:(
(I guess if init dies, I'm screwed too.)
[13:15]
toddfcronjob a check to confirm runit is running [13:15]
mhoranYep.
monit could easily be replaced with some cronjobs and runit.
I like it!
[13:16]
up_the_ironsmhoran: you set runit to start in /etc/inittab (old way) or /etc/event.d (newer Debian / Ubuntu)
mhoran: so it always stays running
[13:17]
mhoranRight. [13:17]
up_the_ironseven if you kill it, it'll restart [13:17]
mhoranYeah. [13:17]
up_the_ironsit's very "unixy", look at the cool stuff I can do:
$ for i in host1 host2 host3; do ssh $i sv status vm-management; done
run: vm-management: (pid 11031) 133590s; run: log: (pid 12944) 1926719s
run: vm-management: (pid 10962) 133570s; run: log: (pid 21526) 205819s
run: vm-management: (pid 4438) 124502s; run: log: (pid 4437) 124502s
$
(host names changed to protect the innocent ;)
[13:18]
mhoranThat's nice. [13:19]
up_the_ironscd $office [13:20]
toddfno wonder my vm came up quickly when you killed it the other month (at my request of course) [13:22]
........... (idle for 51mn)
up_the_ironstoddf: did you try the new console? you can now kill and start your VM yourself ;) Not that I expect you to jump at that option... [14:13]
toddfI will, but not yet, dealing with a cap growth issue at my parents house in their economy puters [14:19]

jeevshowing all that but only selling the barebone [15:12]
***cablehead has joined #arpnetworks [15:13]
up_the_ironsjeev: hah, yeah [15:13]
jeevit's mobo and case i guess [15:15]
up_the_ironsyeah
jeev: thing is, i don't see all too much the value add for screwing in the MB ;) you can buy the case and MB separate, and save money

up_the_irons, you know what KSM is [16:56]
....... (idle for 31mn)
up_the_ironsjeev: nope [17:27]
jeevapparently it makes it possible for you to be able to run more guests than before
http://fedoraproject.org/wiki/Features/KSM
[17:28]
up_the_ironsjeev: i imagine that would be an overall goal anyway [17:29]
jeevhow many do you think i could stuff on a E5420 with 8 gigs of ram
just curious, probably gonna use it to set up a mail server for something unrelated to my shit
[17:30]
up_the_ironsCoW memory across VMs, yeah this concept has been done before
jeev: obviously, that depends on how much RAM you give to each VM
[17:30]
jeevyea i know but CPU wise [17:31]
up_the_ironsdepends how much load you put on each VM [17:33]
jeev:> [17:33]
up_the_ironsthere is no general answer [17:33]
