mkbhow in the world do I get a centos server to sync time
this seems too hard
there's no ntpd installed like there should be and there's no ntpd package
[08:37]
brycecInstall "ntp"? [08:37]
mkbit's called ntp.. great
I should have thought of that
mkb still thinks it should come with the system
[08:37]
brycecheh, have fun :) [08:38]
mkbI think this is caused by it being a vm and the host going to sleep, but I'm going to take an unusual position and argue that something should handle that [08:38]
brycecThings normally do handle that...
eg vmware-tools
Which can keep the guest clock sync'd with the host
[08:39]
mkbhmm.. I would argue that the host should do it, but I guess the vm would try and change the clock and they'd fight
vm has to know either way I guess
and yeah that wouldn't work because the OS isn't going to look at the BIOS clock
[08:40]
brycecFor example, http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man4/vmt.4?query=vmt&sec=4 [08:42]
m0undsonly instance where i think you don't necessarily need to run an ntp client is on guest OS' living in paravirt, but i'm not sure if that' still the case [08:42]
mkbopenbsd is so nice and has all that stuff in the default install... wish I could use it at work [08:43]
m0undsyea, it's nice having stuff there but having the option to use it or not [08:44]
mercutioopenntpd is a lot lighter than ntpd too
you can just cron ntpdate i suppose
i used to cron rdate
it depends how accurate you want to be.
[08:51]
brycecIt's also about readjusting the time. cron+rdate/ntpdate jerks the time back, whereas ntp slowly adjusts the time back so as not to confuse daemons [08:53]
mercutioyeah, but that can be annoying too brycec :)
if the clock is completely off you need -s to do it quickly.
what used to annoy me about ntpd was that if you don't have dns it takes forever to timeout if you use hostname for ntp servers.
but i suppose permanent net access is taken for granted in most situations now days :)
openntpd is nice and light too
but yeah i'm going off on tangents, i think it's bed time for me :)
[08:56]
***mike-bur1 is now known as mike-burns [08:59]
brycecParticularly for a *network* time protocol ;) [08:59]
mercutiothere is quite a few situations where having "reasonably" accurate time is important
but seconds being right isn't necessarily.
some things like nfs it's annoying when clocks aren't synced.
and seconds rather than minutes are important, but for normal desktops etc it doesn't matter so much
i wonder if centos has openntpd
my past experience of rhel/centos was hardly anything was included, and you had to use weird sites with extra rpm's.
[09:00]
brycecPersonally, I'm anal about keeping accurate-to-a-second time. [09:01]
mercutioi like it for logs [09:02]
brycecEspecially logs across services/servers [09:02]
mercutioyeah it's handy there.
but centos seems to be used for lots of appliance type stuff that might not necesssitate internet
i think that's what got me thinking along that path
i wonder what windows uses for time, my linux and windows computers seem to be within a second of each other.
[09:02]
brycecntp from time.windows.com by default [09:05]
mercutiothat wasn't in '98
i wonder when it came in
[09:05]
BryceBotThat's what she said!! [09:05]
brycec'98 didn't have network time support
2000 or xp, as memory serves
[09:05]
mercutiothere was net time in '98 i think actually [09:06]
brycec"net time" yes, which pulled time over SMB [09:06]
mercutiooh net time is even in '95
and windows for work groups 3.2 apparently.
[09:07]
brycecBut that wasn't used unless the computer was part of a domain [09:07]
mercutioi didn't know there was windows 3.2
i thought winodws for workgroups was still 3.11
weird
http://support.microsoft.com/en-us/kb/120944
that lists windows 3.2, but wikipedia suggested that 3.2 was only a chinese language support version

m0undsserver 2000 was a pain in the ass if you wanted to define a specific time server
required a registry hack
old control servers at my previous employer were powered by win2k, but the pueblo opted not to buy the gps time source option
so the clocks on time date generators and whatnot were always wrong and had to be manually synced. i ended up deploying a box w/2 nics, one connected to corporate network and firewalled syncing its time via ntp, then providing ntp service to the airgapped network
such awful hack stuff, but it kept the time synced til all that stuff got ripped out
[09:29]
brycecNot truly airgapped then, was it ;P [09:35]
m0undsairgapped within the scope of compliance regulations, it was
no listening services, no external access
i couldn't even get them to splurge and requisition an old rackmounted box from IT, i had to use a beat to shit ancient athlon thunderbird desktop
[09:35]
brycecheh [09:37]
m0undsafter i left, they lost their budget for in-house technical staff :) [09:38]
brycecRemind me not to gamble in NM
hell, remind me not to go to NM :p
[09:39]
m0undsyou're missing out on the food dude
food, mountains and beer
[09:39]
brycecI've been there several times, never impressed
The scenery wasn't much of anything different from home
I don't care for beer.
[09:42]
m0undsthen you're unfit for NM, GOOD RIDDANCE [09:42]
bryceclol [09:42]
staticsafeD: [09:42]
brycecAnd food... I wasn't picking where to eat so I've only had chain stuff :/ But I've had NM food elsewhere that was good. Just not worth going to NM for it :p [09:43]
m0undsmost of our tourism centers around people wanting to go to santa fe or taos, or wanting to do breaking bad tour shit (which i really wish would stop) and less about the science tourism that used to be a thing when i was a kid [09:44]
brycecI think American culture in general is disinterested in "science tourism" [09:45]
m0undsprobably so [09:46]
brycecIsn't the balloon festival in ABQ
?
[09:46]
m0undsoh, right
forgot about that, but it's only one week out of a month
in oct
[09:46]
brycecQuite so. Still, one of NM's strongest tourist draws. [09:47]
m0undsand the last few years, it's been raining or too windy to launch every day so they've had fewer visitors (but still on the order of hundreds of thousands)
lots of people come in for skiing in taos and santa fe
[09:47]
brycec"Look everybody, FLIGHT! How novel!" (I don't really get it) [09:47]
m0undsstill lots of interest in outdoor activities
they look neat, that's about it
[09:48]
brycecI could look at pictures from home
in my underwear
[09:48]
m0undsthe glowing pre-drawn is cool, and the tethered grounded inflated balloon glows at night are kind of neat [09:48]
brycec(Something tells me there's very little tourist traffic from Arizona to New Mexico) [09:48]
m0undscasinos draw people from AZ for some reason
i'd guess it's because most AZ casinos are shitty
[09:49]
brycecI've been to a couple AZ, I didn't find them *that* shitty as to drive over to NM [09:49]
m0undsat least the ones in eastern AZ are (i've been to too many of them for work) [09:49]
brycec(but it depends where you are) [09:50]
m0undsyea [09:50]
brycecI would sooner drive the 6 hours to Las Vegas... [09:50]
m0undsi'd rather drive 6 hours to denver than 9hrs to vegas
haha
i think it's 9hrs, might be more
probably more accurate is that i'd rather drive 6hrs to denver than fly to vegas
[09:50]
brycecHeh, for sure [09:52]
m0undsmy wife is dragging me to a conference in LV in october [09:52]
BryceBotThat's what she said!! [09:52]
m0undsBryceBot: no [09:52]
BryceBotOh, okay... I'm sorry. 'my wife is dragging me to a conference in LV in october' [09:52]
m0undsactually, it is what she said
lol
[09:52]
brycec6 hrs is an easy enough drive, plus you can pack and leave whenever you want. Easily worth it over flying for the same difference.
But 9 hours' drive...
[09:53]
m0undsi think it's like a 70min flight [09:53]
brycec45min from Phoenix [09:53]
m0undsusually ~$120 to fly round trip from abq to lv
same to fly to LA, and i don't care for CA that much but i'd rather go to LA than LV
that part of CA anyway, norcal is nice
[09:53]
brycecPlus travel, packing, parking, etc it ends up being 4 hours to fly vs 6 hours to drive, and then usually worth the convenience of having your own car.
lol
[09:54]
m0undsyeah
the drive i usually take from here to denver area is nice (i'm from boulder, so we tend to stay out that way)
[09:54]
brycecThat's cool [09:55]
BryceBotThat's what she said!! [09:55]
m0undsUS-285 through alamosa, buena vista, leadville, then east on i-70 to denver
it's great as long as it's not winter
buena vista and nathrop are right along the arkansas river amongst the MIGHTY COLLEGIATE PEAKS
mt harvard, mt princeton, etc
http://en.wikipedia.org/wiki/Collegiate_Peaks
[09:55]
BryceBotCollegiate Peaks :: The Collegiate Peaks (or Collegiate Range) is a name given to a section of the Sawatch Range of the Rocky Mountains located in central Colorado. Drainages to the east include headwaters of the Arkansas River. The Collegiate Peaks include some of the highest mountains in the Rockies. The section is so named because several of the mountains are named for prominent universities. Prominent peaks See also Mountain... [09:56]
