up_the_ironssjackso: we're definitely going to be publishing a pricing table , most likely on https://www.arpnetworks.com/dedicated . I've been debating whether it should go on a separate page, but I don't want there to be confusing as to which offering is "dedicated". They both are, just in a different way.
It's no longer the case that physically different boxes need to be used to actually dedicate resources to a client
sjackso: how much RAM in those E3 systems for $50 from the budget providers?
nathani: brycec plett : I would just use the onboard watchdog. I haven't seen a MB in a while that didn't have that feature. 		[17:37]
brycecBut does esxi support onboard watchdog devices? [17:40]
nathaniI currently have the system tail the /var/log/syslog.log file via an ssh session to see if shows any errors before crash [17:41]
up_the_ironswell, can esxi load regular linux kernel mods? sorry, i don't have much experience with esxi
here's something we have on our older systems:
$ cat /etc/modprobe.d/watchdog.conf
# Choose which watchdog to use and blacklist the other one
blacklist iTCO_wdt 		[17:42]
brycec(me either, though I have vcenter access to a few...) [17:43]
up_the_ironsoptions iTCO_wdt heartbeat=300 nowayout=0
options ipmi_watchdog timeout=300 nowayout=0 action=power_cycle
$ 		[17:43]
brycec(Google turns up surprisingly few notes on configuring host watchdogs in esxi :( ) [17:44]
mercutiobrycec: that's what i was searching for :)
i thought the sensible approach was google
you could just stick linux/kvm on it.. 		[17:44]
nathaniyea [17:46]
mercutiobut first [17:46]
nathaniI like the click click gui proviced by VMware [17:46]
mercutioi would see if they can get your box to not crash [17:46]
brycecMan I don't know wtf is up with my Arch desktop, but it's been sporadically failing to resolve. ssh and curl just fail "Name or service not known" yet host and dig resolve just fine. And if I wait a bit, it eventually works... [17:46]
mercutiowatchdog is a bandaid
bryce: are you usin ga router for dns or your isp>?
or your own name server..
sometimes router dns forwarders are really terrible 		[17:46]
brycecmy own forwarder [17:47]
mercutioahh [17:47]
brycec(unbound)
And again, dig/host against that work just fine. It is somehow per-program that it's failing 		[17:47]
mercutioi would run tcpdump on port 53 and write it to a file
if you have more than one forwarder i wonder if one is failing and it's trying too frequently to use it 		[17:47]
brycecHere's what's crazy - There's NO TRAFFIC when it fails
brycec blames systemd 		[17:48]
mercutiooh wow
is it doing that systemd listen on port thing? 		[17:48]
brycec? [17:48]
mercutioie make systemd like inetd
i only just learnt about that recently 		[17:48]
brycecOh, the forwarder is on another host. [17:48]
mercutioahh
and it works fine from other hosts? 		[17:48]
brycecAnd when I try curl/ssh, while tcpdumping, it doesn't even try to connect [17:49]
mercutiook
that is random
i haven't actually done an update in a while
i kept finding the updates would kill my X... 		[17:49]
brycecYeah, though I think that's irrelevant. It's this host not even trying to resolve, except for host/dig... And eventually ssh/curl will work. Makes no sense. [17:49]
mercutioso now i'm hoping when i update i don't hit that [17:49]
bryceclol [17:50]
mercutioi was using beta mesa i think [17:50]
brycecThis is spanning updates, even. (about 30 days' worth) [17:50]
mercutiohmm [17:50]
brycecAnd Google hasn't given anything :( [17:50]
mercutioyou haven't done anything crazy with nsswitch.conf?
or resolv.conf 		[17:51]
brycecNope. It's completely stock. (though I fiddled with it to no avail, moving resolve up higher in the hosts order.) [nsswitch.conf] [17:51]
mercutiowtf
i thought i'd try netstat.. 		[17:52]
brycecAlso - While curl/ssh fail for the host I'm trying for, they resolve other hosts just fine. [17:52]
mercutioand google chrome listens on port 5353 [17:52]
brycec^ Chromecast listner
*listener 		[17:52]
mercutiooh
i was grepping for :53
i'm using dnsmasq at home
i assume you've tried setting your dns straight to your isp
in case it makes any diff? 		[17:52]
brycecsonofa... It's systemd-resolved doing... something. [17:54]
mercutiohahaha [17:54]
brycec"Using degraded feature set (UDP) for DNS server" "Grace period over, resuming full feature set (UDP+EDNS0+DO+LARGE) for DNS server" [17:54]
mercutioi don't have systemd-resolved
i didn't even know there was such a thing
it's like nscd? 		[17:54]
brycecI think I know what's happening... systemd-resolved is barfing about unsigned domains.
https://www.freedesktop.org/wiki/Software/systemd/resolved/
Maybe like nscd, not sure 		[17:55]
mercutioi'm reading about resolved
it seems like ncsd
ncsd used to leak
and do other nasty thing 		[17:56]
BryceBotThat's what she said!! [17:56]
mercutiowell leak and crash iirc [17:56]
brycecsystemctl stop... And ssh works :) [17:56]
mercutioit does seem strange to not hash /etc/passwd
but it doesn't seem to hurt that bad 		[17:57]
brycec(Thank you #arpnetworks for being a sounding board) [17:57]
mercutioi wonder when arch introduced it [17:58]
brycec*introduced* or *enabled* ;) [17:58]
mercutiomade it standard
i have systemd-resolve binary
if you want to use systed-resolv you're meant to set resolve instead of dns in nsswitch.conf 		[17:58]
brycecI can reliably reproduce this too, at least. If I restart resolved then query it directly over 127.0.0.53 I get the same failures as curl/wget saw.
This is the stock nsswitch.conf on my Arch machine, note that it tries resolve first and fails completely if it fails.
hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname 		[18:02]
mercutiook
mine is nothing like that
% cat /etc/nsswitch.conf | grep ^host
hosts: files dns
i might have got annoyed at it or something though 		[18:03]
brycecDo you have any nsswitch.conf.pacnew or similar files? [18:03]
mercutionope
my nsswitch.conf is dated feb 9 2015
hmm i checked another box and it has the same nsswitch.conf 		[18:03]
brycechttps://git.archlinux.org/svntogit/packages.git/tree/trunk/nsswitch.conf?h=packages/filesystem
^ the "filesystem" package is what installs nsswitch.conf, so that's the authoritative source
It was modified 5 November https://git.archlinux.org/svntogit/packages.git/commit/trunk/nsswitch.conf?h=packages/filesystem&id=f1cd9f7fb4cdf7617a1b875e14be212733f9c67a 		[18:04]
mercutiohmm
but both of those have resolve 		[18:06]
brycecbrycec stabs at https://bugs.archlinux.org/task/51709
(And now I've found others with the same issue as I :P) 		[18:06]
mercutiohosts: files dns myhostname
i found something with that
but nothing with resolve 		[18:07]
brycecmercutio: what version filesystem package do you have? pacman -Qi filesyste m
(minus typo ;)) Should be 2016.12-2... 		[18:07]
mercutioVersion : 2015.09-1 [18:07]
brycecwtf mercutio
why haven't you updated in over a year? 		[18:07]
mercutioi have [18:08]
brycecNot that package, you haven't... [18:08]
mercutiothere prob wasn't an update
https://git.archlinux.org/svntogit/packages.git/log/?h=packages/filesystem

it's more like i haven't updated in a month 		[18:08]
bryceclol I see [18:09]
mercutiowhich is still a little bad [18:09]
brycecSo you've somehow missed the last 6 package versions because they were all in the last 5 weeks. Got it. [18:09]
mercutioheh
hangon this is strange
filesystem-2016.11-2-x86_64.pkg.tar.xz
i have that downloaded
but not installed. 		[18:09]
brycecBack to the topic of ESXi watchdog support (now that I can ssh to an esxi box), it does not appear there are any modules for watchdog support. SATA, network, SCSI, USB... Even one called ipmi_ipm, but nothing else it looks like, nothing watchdog. [18:22]
mercutiowhat about in dmesg?
as it may be built into kernel 		[18:25]
bryceclol
Have you seen an esxi dmesg? It's not remotely linux-like... And given that the machine has been running quite awhile, any boot messages are long gone.
~ # dmesg | head
2016-12-12T16:50:37.276Z cpu4:35581)World: 14299: VC opID hostd-5d48 maps to vmkernel opID c6486b8
Also, the kernel is 44kb, probably not built-in
File: /bootbank/tboot.b00 Size: 44343 		[18:33]
mercutiooh
it seemed busybox like to me 		[18:39]
brycecIt's a fairly unique kernel, in my experience. Unix-like, sure, and the kernel was definitely based on Linux, but... it's not recognizable as "Linux" these days. [18:46]

up_the_ironsjpalmer: you can just type here, or PM, and i'll get to it when I can :) email is also OK. If it's support related, support@ gets the fastest response.
when i get home, i'll be with the kids until they go to bed 		[19:17]
jpalmerit's more of a billing thing, but somewhat complicated, which is why I tried to raise you here.. so we could talk realtime. I'll send you a PM [19:17]
