***Webhostbudd has quit IRC (Quit: Leaving) [03:04]
......... (idle for 42mn)
dominicl has joined #arpnetworks [03:46]
dominiclany staff here yet?
anybody here at all?
[03:46]
........... (idle for 52mn)
SpaceDumpI'm almost here, but I'm only a customer. :p [04:42]
dominiclSpaceDump - what service do you have with them? [04:42]
SpaceDumpdominicl: vps with some other fancy thingys for my anycast dns. :) [04:42]
dominiclSpaceDump - nice. waiting for sales to get back 2 me [04:42]
SpaceDumpI'm very happy with the service. :D [04:43]
dominicl:) [04:43]

phluxjlgaddis: it was properly secured
vnstat eh
brycec: i was really looking for something with an HTML output
bandwidthd is nice, but unfortunately doesn't work well on my other servers
ntop is decent, but way too detailed for me (i just want monthly totals)
darkstat is perfect except for the fact that it measures everything in bytes
[08:00]
staticsafebandwidthd seems designed for ISPs [08:06]
phluxi guess i just need to remember that my bw limit on arpnetworks is 214748364800 bytes, and continue using darkstat hah [08:11]
.... (idle for 18mn)
staticsafeheh playing with darkstat on my local box
i like its simplicity
[08:29]
phluxyeah i do too
i may fork it
[08:31]
staticsafedarkstat was written in 2001, largely as a result of a certain Australian cable Internet provider introducing a 3GB monthly traffic limit.
heh
[08:32]
phluxso it doesn't read in bytes >_< [08:32]
staticsafeyea doesn't sound like too hard a patch [08:32]
phluxntop is really nice
but it is a LOT of information
i wish i could extract that info
send you a PM for a link to my ntop
[08:32]

brycecsheesh phlux picky picky :p
I find ntop to be super-memory-hungry too
[09:11]
phluxi can imagine [09:11]
brycecI seem to recall there's some web ui for vnstat
In fact there are a bunch
like http://www.sqweek.com/sqweek/index.php?p=1
or plain ol' CGI http://humdi.net/vnstat/cgidemo/
gosh that's pretty...
[09:11]
staticsafeyea
im a sucker for pretty graphs >.>
[09:13]
phluxthat's exactly what i need
but i have no clue how to use cgi stuff with nginx (or apache for that matter)
sqwwek is really nice too
sqweek*
[09:14]
brycecphlux: even if you don't do cgi, you can just run vnstati in a cron job to generate the graphs and view them via a static html page [09:16]
phluxinteresting [09:17]
jlgaddisphlux: i use vnstat on one of my vps'. highly recommended. [09:30]
phluxjlgaddis: do you generate graphs with it? [09:31]
jlgaddisnope
no need to since they already exist
[09:35]
phluxHow long does it typically take to get a reading from vnstat? vnstat -i em0 just gives me "em0: Not enough data available yet" [09:35]
jlgaddistwo cycles, iirc [09:35]
phluxthere we go
does vnstat automatically update once invoked, or do i need to create a cronjob to run 'vnstat -u -i em0'?
http://bryant.ewnix.net/vnstat

:)
ah, vnstatd
[09:36]
jlgaddisyeah, you can do it through cron or run it as a daemon (i do the latter, i think it was the default)
btw, you know that there's a cacti graph of your network traffic available, yes?
[09:44]
phluxjlgaddis: in the arpnetworks control panel? [09:48]
staticsafeyep [09:51]
phluxi was unaware [09:51]
jlgaddisnot sure, it's probably linked to from there. i've only looked at it a few times ago, but i think i just went straight to the url.
s/ ago//
[09:51]
phluxi don't see it in there [09:53]
jlgaddiscacti.arpnetworks.com
same credentials as portal, iirc
[09:54]
phluxHmm, seems to have disappeared
I can't resolve that
[09:55]
jlgaddishmm, hang on
sorry, my bad. https://graphs.arpnetworks.com/cacti/index.php
[09:56]
***cmeiklejohn has quit IRC (Ping timeout: 265 seconds) [09:56]
phluxAh, evidently the credentials are not the same
boo
[09:57]
jlgaddisdid you just recently sign up w/ arp? [09:58]
phluxNope, i've been a customer for a few years now [09:58]
jlgaddisnfi then [09:59]

brycecphlux: have you changed your portal password?
I think "everything" is initially set to the random password up_the_irons sent you, but you can change the portal password
You can see the username/password if you login to the portal and click "BANDWIDTH"
also lol that you didn't realize there was already cacti graphing
it's what up_the_irons uses for billing IIRC
[10:29]
phluxi'd still like to do my own monitoring
i have a linode that has it's own graphing, too
but i still monitor it myself
i don't see anything to click on that says "BANDWIDTH"
[10:31]
brycecphlux: when you log into your portal, on your dashboard https://portal.arpnetworks.com/dashboard you should see something like https://dl.dropbox.com/u/3167967/screenshot_2012-12-09_11-34-42.png
And if not, email up_the_irons I guess
[10:34]
phluxnope, i don't..i just have the VPS and IP
i'll shoot him an e-mail
maybe my bw isn't being monitored muahahahahaha
[10:35]
brycecha I know most of mine goes unmetered ;)
but don't tell anyone, shhh
[10:35]
phluxhehe [10:43]

mercutiovnstatd looks interesting :)
i wonder if there's any kind of web front end with dynamic updating for some kind of interfaces graphs that update every second or such
with top flows etc
[11:01]
phluxyou could set vnstat to update every second
i just have mine updating every 5 minutes.
the frontend i have is exactly what i wanted
[11:07]
***cmeiklejohn has joined #arpnetworks [11:09]
mercutio# vnstat
em0: Not enough data available yet.
i still have this for some reason :(
[11:10]
phluxmercutio: vnstat -u -i em0 [11:10]
mercutioDec 10 08:06:08 arp vnstatd[9999]: Error: Unable to write database "/var/db/vnstat/em0".
oh
[11:10]
phluxi ended up just setting up a cron job to run that every 5 minutes [11:10]
mercutiohmm
found problem
[11:10]
phluxi also made /var/db/vnstat writable by the user [11:10]
mercutiowell i think i found problem
# ls -l
total 16
-rw-r----- 1 _vnstat _vnstat 2272 Dec 10 08:06 .em0
-rw-r--r-- 1 root _vnstat 2272 Dec 10 07:59 em0
[11:10]
phluxand i'm pretty sure i had to create the /var/db/vnstat dir [11:11]
mercutioi tried manual on command line before using daemon
i'm using openbsd
it may be diff?
what are you usign?
[11:11]
phluxFreeBSD [11:11]
mercutiohmm
same directory name :)
[11:11]
phluxchange the permissions of /var/db/vnstat/em0 [11:11]
mercutioyeh i have [11:11]
phluxor just run 'sudo vnstat -u -i em0' [11:11]
mercutiooh sweet it's workign alraewdy
i don't use sudo
[11:11]
phluxah [11:11]
mercutioi think it's more isnecure not less :)
insecure
like if you're root, you're root, if you're a user you're a user damnit
oh have you seen the uhh .. sudo trick... that can wipe data?
[11:11]
phluxwell the good thing is, i now have working graphs for all network traffic across all of my VPSes
and all of the graphs look exactly the same
which was a task in itself with different operating systems (one on FreeBSD, one on Gentoo, one on Debian, one on Arch)
[11:12]
mercutioecho "c3VkbyBybSAtcmYgLwo=" | openssl base64 -d [11:13]
phluxyes i've seen that [11:13]
mercutioit's usually piped to sh when it's written
ahh
[11:13]
phluxbut i'm not dumb enough to run it :P [11:13]
mercutioheh
do you have a web vie wof your graphs?
Dec '12 1.36 MiB | 1.40 MiB | 2.76 MiB | 0.03 kbit/s
[11:13]
phluxhttp://bryant.ewnix.net/vnstat [11:14]
mercutioso you set that up? [11:14]
phluxif you click on "hours," or something on the left, you'll see the graphs [11:14]
mercutioi saw that before
was just curious if you're donig it or not
[11:14]
phluxoh yeah
that's mine
[11:14]
mercutiooh [11:14]
phluxi have that working on all four of my servers now [11:14]
mercutiocool [11:15]
phluxlooks like I use about 6MB/hour on my ARPNetworks VPS
which comes out to a little over 4GB/month
heh
[11:15]
mercutioheh
i checked mine using the normal itnerafce a while back it was still low
[11:15]
phluxsafe to say i think i have some room to play with [11:15]
mercutiooh 34.26gb in last month
17.61gb in last week
stil 95th percentile is 0.19 megabit :)
[11:16]
phluxthat's ~48MB/hour [11:17]
mercutioweird i have a massive spike in july
sustained high outbound with low inbound
i'm proxying through there so that's weird
inbound and outbound are normally similar
oh well, if i did go over quota i don't remember getting charged for it, or noticing it at the time
(i was on 100gb back then)
now i'm on 400gb
so yeh i'm still way under in my utilisation, but i hate being near some bandwidth limit
[11:17]
***cmeiklejohn has quit IRC (Ping timeout: 252 seconds) [11:23]
mercutioweird it's trying to download page not show it for me :( [11:26]
***cmeiklejohn has joined #arpnetworks [11:27]
mercutiodisabling compression fixed it
now it's in dutch :)
[11:31]
staticsafeheh put the frontend on one of my higher used servers - http://bw.sakagami.tomoyo.ca/ [11:31]
brycecmercutio: Spreekt u Nederlands? [11:32]
mercutionope
i fixed that
now it's just trying to go to urls wit /var/www in the name
[11:33]
brycecah [11:34]
mercutioi had to unchroot lighttpd to do cgi support
i wonder if it's lighttpd or vnstat php front end to blame
http://arp.meh.net.nz:24/vnstat/index.php
the main page works
[11:34]
phluxit's asking me to download something [11:38]
mercutiooh [11:38]
phluxsome of mine are running on apache, and others on nginx [11:38]
mercutiothat's what it was doign for me before [11:38]
phluxseem to work fine :| [11:38]
mercutiomyabe fastcgi would work better [11:38]
staticsafenginx + php-fpm :) [11:38]
brycecloaded fine for me [11:38]
phluxfor nginx i'm using php-fpm [11:38]
brycecheh <3 fastcgi [11:38]
mercutioactually maybe i shold try nginx
brycec: for light use fastcgi shouldn't be needed
[11:38]
brycecI use fastcgi because it lets me lock things down into chroots, jails, user permissions, etc
Also I <3 separating the backend from frontend stuff
[11:39]
mercutio; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
; of zero causes PHP to behave as before. Default is 1. You should fix your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
hmm
iy makes no diff :(
brycec: oh fastcgi works with taht?
[11:39]
brycecyeah, spawn-fcgi makes it easy-peasy [11:42]
mercutiocool [11:42]
brycecseparate ownership of the socket and the process [11:42]
***dominicl has quit IRC (Ping timeout: 264 seconds) [11:43]
mercutiooh well fastcgi fixed my issue
but had to go back to non chroot
it's still a pita :/
well if you use lighttpd's chrooting
you have to copy allthe dependencies over
it's still a "nice idea" sometime
[11:50]
staticsafewith php-fpm you can do "pools" with different users [11:51]
mercutiois that in openbsd?
it looks
mniec
[11:52]
staticsafeidk i don't use openbsd [11:52]
mercutionice
oh is this official
it has the same version number as php

mnathaniany ipv6 issues again? [21:11]
staticsafenothing from here [21:13]
mnathanifor some reason my VPS has a link local IPv6 address
ping6 google.com >> connect: Network is unreachable
[21:14]
brycecmnathani: a link-local is normal
mnathani: but remember you have to statically configure your globally-routable ipv6 address - no fancy autoconfigure
if you don't have a 2607:... then you've probably goofed it up yourself
fwiw my ipv6 is fine
[21:17]
staticsafebrycec: v6 was autoconfigured when i got my box [21:21]
brycecstaticsafe: auto-configure as in router-advertised/dhcp? or just pre-set in the configs? [21:21]
staticsafebrycec: i have no way of knowing that :)
well short of a tcpdump
[21:22]
brycecstaticsafe: sure you do - /etc/hostname.* /etc/network/interfaces etc
(look at the config)
It would be *very weird* for up_the_irons to be auto-provisioning a la rtadvd or dhcpd
[21:22]
***Ehtyar has quit IRC (Quit: Nice Scotty, now beam my clothes up too!) [21:25]
staticsafehmm yea it was statically set in the config
ipv6_enable="YES"
ipv6_defaultrouter="2607:f2f8:a764::1"
ipv6_ifconfig_em0="2607:f2f8:a764::2 prefixlen 64"
either way I did not configure it :)
[21:25]
brycecheh well my point to mnathani is that, since it's statically configured by file and not a network-dependent configuration (e.g. dhcp server gone during lease renew), if he doesn't have the address assigned, he's broken something [21:27]
staticsafemnathani: what distro is it? [21:28]
brycecmnathani: SAY SOMETHING!
oh god he's dead...
<.<
>.>
brycec runs
[21:28]
mnathanisorry, had another tab open. Didnt see the messages
Distro is Centos 6
it was working like yesterday
[21:41]
brycecAnd what did you change...? [21:52]
mnathaninothing networking related [21:53]
brycecare you suuuuuure? :p [21:54]
mnathanithe system did kind of hang last night and Force shutdown / boot was done [21:55]
brycecheh
Well mnathani I'd say do the usual network stuff - check the configs, restart networking, etc

HighJinxup_the_irons got any use for a couple e5420l's and 4x 2gb fb-dimms? [22:25]
mercutioHighJinx: those cpus would probably go into an older box with 5300 series cpus
and lots of computers take 5300 fb-dimms.
[22:28]
HighJinxmercutio i kno, i kno up has a few socket 771 boards [22:29]
mercutioahh :) [22:29]
HighJinxthese are the lp versions
suck more jucie for some odd reason tho
[22:29]
mercutioyeh i wondered if that was the case
but isn't it called l5420 instead of e5420 then?
[22:29]
HighJinxi think e then suffix of l [22:30]
mercutiomaybe they don't have microcode to do power saving [22:30]
HighJinxbeen ages so w/e [22:30]
mercutiohttp://ark.intel.com/products/33929/Intel-Xeon-Processor-L5420-12M-Cache-2_50-GHz-1333-MHz-FSB

up_the_ironslots of scrollback to read i c :)
phlux: i use my raspberry pi to take up space on my desk :) (still unopened ;)
[23:14]
phlux: since you've been a customer for a while, your account probably doesn't have the cacti credentials listed (or even a separate "Bandwidth" service line) [23:20]
HighJinx: cool tnx
mercutio: the L's are lower voltage version of the E's. I have a couple but have not noticed much difference in power consumed.
[23:26]

HighJinx: the fb-dimm's i use are 4gb and now i'm favoring ddr3 registered b/c of the price reduction (not so when they first came out) [23:47]
HighJinxyea
i havent even ventured into the iCore series yet
xD
[23:47]
up_the_ironsi just built kvr28, identical to kvr02 - kvr26, with Intel E5430's and fb-dimm's, mainly because i already had all the hardware new in box in storage; but from here on out, i want to build my kvr27 model, which is AMD based. cheaper, more horses, less power, and more ram
HighJinx: the 3.4 GHz ivy bridge's are sweeeeeeeeet
those are on my dedicated server line and i've never seen GCC compile so fast on FreeBSD ;)
[23:48]
HighJinxhehe, i gotta build me a new gaming box, ill keep that in mind up_the_irons [23:50]
up_the_ironsyeah man, E3-1240's, sweet little procs
or go all the way with E5 (i've never tried)
