mnathaniwhat good is a Serial port available over SSH for server management? [02:28]
plettmnathani: Very good, in my experience [02:37]
mnathanihow would one use it? [02:37]
plettYou would ssh to somewhere which isn't your server and get yourself connected to the serial console of your server [02:38]
mnathaniwould that be kind of like a kvm? [02:38]
plettI believe so. I've never really seen the need for KVMs - you don't run GUIs on servers
It means that if your server is able to display boot messages on the serial port you can see why it's not booting, or you can log in to it and undo the firewall rule that mistakenly locked you out of the network interface

tooth: jdoe : I had a customer years ago that plugged in AT&T, Cingular, Verizon, etc... PCI cards into his 1U Windows box and was able to send SMS that way. I know it seems overkill but it did in fact work.
well, like 2 were PCI cards and the rest were USB dongles

andolup_the_irons: On the resolver side it ought to be fairly trivial, at least assuming bind alt. unbound. Basically it is enabling an option or two and make sure that you have a copy of the (public) root key.
(Serving authorative domains using DNSSEC is a bit more work, especially getting resigning, key rotation, etc they way you want it.)
[07:01]
..... (idle for 20mn)
up_the_ironsandol: roger that
andol: one of our resolvers is bind, the other is unbound. I'm planning on making a brand new resolver to replace the bind one (and it'll be unbound)
[07:22]
mercutiounbound is nice :) [07:24]
plettYes, unbound is much nicer than bind. I use anycasted unbound servers for customer facing resolvers [07:29]

..... (idle for 22mn)
mercutiowell i more compare it to powerdns or dnscache
bind is disgusting :)
i was slightly surprised how quickly unbound caught on
but really, it's the people who are doing anycasting, multiple servers, large cache sizes, long ago split their dns between forward and recursive etc.
and lots of small installs are still using bind et.c
[08:04]
toothi'm using NSD myself [08:08]
***Webhostbudd_ has joined #arpnetworks [08:10]
mercutioi didn't realise nsd did recursive?
unbound only does recursive
i use tinydns for authorative
[08:14]
toothnsd only does authoritative. [08:16]
twobitha1kerunbound can do some auth [08:16]
mercutiotwo: only as much as things like dnsmasq?
dnsmasq is actually handy for home use
cos it does small caching recursive, dhcp, can publish records straight from /etc/hosts
[08:16]
twobitha1kerlocal-zone stuff in the config [08:17]
mercutioit even makes windows default host names pingable :) [08:18]
twobitha1kerI just recently switched my home router to dnsmasq, it is pretty slick [08:18]
mercutiofrom the dhcp
yeh
ok i didn't know that two
i know about forward-zone?
# local-data: "mycomputer.local. IN A 192.0.2.51"
i see
that's probably similar to dnsmasq where you can just have some host names have ip's that don't go to another dns server
rather than being suitable for publishing on the net/
you don't relaly want an open resolver
[08:18]
plettI use unbound for resolvers and a combination of bind and nsd for authoritative
I don't yet serve authoritative DNSSEC records (but do validate them in unbound). I'm considering moving to PowerDNS and using its live-signing setup where I just give it a key and ignore it, no need for periodic re-signing etc
[08:29]
..... (idle for 21mn)
jdoeI'm not sure how that works, unless you never do key rollover.
since you need to update the keys with your registrar, which is a manual step :P
[08:51]
plettIt can be automated, but yes [08:53]
jdoewith what registrar? [08:53]
plett.uk and RIPE reverses are both automatable
The other reason I'm interested in PowerDNS is it's ability to serve DNSSEC signed data from a programatic or database driven backend where it's not feasible to know the previous/next records for NSEC purposes
(It helps that the company I work for is a RIPE LIR and a Nominet registrar)

jpalmerup_the_irons: I have no doubts about that. It's an "all eggs in one basket" kinda thing. we have vps/dedi's spread across about 30 different data centers. [10:52]
................ (idle for 1h19mn)
toddfjpalmer: 30 different data centers? thats some asset allocation scheme you're pushing there. [12:11]
up_the_ironsjpalmer: wow, cool :) [12:17]
jpalmertoddf: we've built a "mesh network" of openvpn servers for our management network. openvpn can't handle a ton of traffic, so we had to scale up the number of servers.
obviously, not all of the vps's or dedi's are openvpn.. but we have at least one at each datacenter.
[12:30]
toddfopenvpn can't handle a ton of traffic? is its limitation the fact that it throws all encryption through a single userland process or ? IPSec I guess is not an option for some reason? [12:32]
jdoeit's just less efficient than in-kernel ipsec.
it can handle "a ton of traffic" (for varying definitions of a ton, hardware dependent), it just suffers from additional overhead.

ryki don't seem to be able to vnc into my console through either method (tunnelling or direct)
anyone else having an issue?
[13:50]
arenlormailman still the suggested program?
ryk: You getting an error?
[13:58]
ryknah, just timing out
"Connecting..."
[14:00]
arenlorryk: What client? [14:01]
rykchicken.app, worked for this vps in the past. [14:01]
arenlorNever heard of it, was going to see if I had it somewhere.
Got another VPS to try?
[14:01]
rykit's a fork from chicken of the vnc [14:02]
arenlorYou rememered to enter the correct port I'm assuming? [14:03]
rykyeah, i don't have another vps to test against, but i know it's powered on, i can ssh in to a login prompt, but i forgot my username/password.
i had the preset in chicken.app saved, and of course the arp console gives you copy/paste ssh instructions.
both of them worked previously, i was just wondering if console.cust.arpnetworks.com might be down or something.
i thought i had ssh keys set up on the vps but apparently not
[14:04]
arenlorryk: You can submit them at any time. [14:07]
ryki have them in to the host, yes
i was talking about my instance.
was just hoping that someone else could confirm if the console server was down before i contact up_the_irons
[14:07]
arenlorryk: It seems to be working for me so far. [14:09]
rykok, thanks. [14:12]
arenlorryk: What host are you on? [14:13]
rykkvr19
i can get in to the ssh console and even my ssh, but i just can't log in
just wanted to get in to my local vnc console because i think i left it logged in.
i can reboot, go into single-user mode, etc to reset my passwords, from the ssh console, but now i'm just wondering why my vnc console isn't working.
[14:14]
arenlorryk: Yeah. Did it die maybe? [14:15]
rykit definitely didn't, because the serial console puts me at a login prompt
with my hostname and everything
[14:16]
***fink has joined #arpnetworks [14:17]
arenlorYour vnc port isn't 6059 right? [14:21]
rykit is 5955 [14:22]
arenlor6059 is all the nmap is showing for it as open. [14:23]
rykoops, my port is actually 6057
i was looking as the ssh command at the local port
so that suggests that the kvr19 host itself is not listening
[14:29]
***portertech has left [14:32]
arenlorryk: It would seem so. [14:33]
rykI wasn't getting tripped up by the console server. that's only an ssh server used to bounce in

mercutioup_the_irons: that looks like a crash in the interrupt handler of the em ethernet driver :( [19:46]
up_the_ironsmercutio: ah
interesting
[19:47]
mercutioyeh, but why's it happening :) [19:48]
***HighJinx has quit IRC (Quit: Computer has gone to sleep.) [19:48]
mercutioi had some stalls on em driver, before, using a more recent kernel seemed to help
but that showed up in dmesg
the em driver is the most used network driver..
well, ok it may not be most used.. realtek may be used more
but with people doing "important" things it's very very common
[19:48]
awyeahhrm, time to freebsd-update [19:53]
mercutiohttp://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/if_em.c
based on that there was some kind of crash from running out of file descriptors fixed in openbsd 4.7
but that's ages ago.
[19:54]
i'd actually suspect that em_rxeof crash on the descriptor thing after reading logs and google
and that upgrading openbsd version could fix it
or just patching the ethernet driver and recompiling kernel

mercutio23.20.0.0/15 23.22.0.0/15 50.17.0.0/16 50.19.0.0/17 50.19.128.0/17 54.240.8.0/21 54.242.0.0/15 67.202.0.0/18 72.44.32.0/19 75.101.128.0/17 96.127.0.0/18 96.127.0.0/21 96.127.0.0/24 96.127.32.0/19 107.20.0.0/16 107.21.0.0/18 107.21.64.0/18 107.21.128.0/17 107.22.0.0/16 107.23.0.0/17 174.129.0.0/16 184.72.64.0/19 184.72.96.0/19 184.72.128.0/17 184.73.0.0/16 204.236.192.0/18 204.236.224.0/19 205.251.236.0/22 216.182.224.0/21 216.182.232.0/21
not nearly as much as hp and the liek
arenlor: it's about autoconfig etc
[22:39]
pcnTrue, they're not legacy. But that list will continue to grow [22:39]
mercutioit is quite a few
oh 23.20.0.0/15 and 23.22.0/15 could be merged
into 23.20.0.0/14
i still think it's less than hp :)
i don't have ipv6 bgp
so i have no idea how many /32s are on there
or anything bigger
[22:39]
up_the_ironsthe whole IPv6 routing table is about 10K prefixes
i remember when it was 600 :)
(circa 2007)
[22:42]
mercutiohmm
that's not too bad
[22:43]
arenlorup_the_irons: How much does it cost you for your /32? [22:43]
up_the_ironsarenlor: not sure separately, it is bundled with my IPv4 allocations ($2250 per year) [22:43]
mercutiothat doesn't seem that crazy [22:44]
arenlorI wonder if IPv4 will ever go away. [22:44]
mercutio174.136.96.0/20 206.125.168.0/21 206.162.240.0/20 208.79.88.0/21
hmm you have a few ip addresses
48 class c's?
[22:44]
up_the_ironsmercutio: i think it's a /19 equivalent [22:52]
mercutiotwo /20s make a /19 [22:52]
up_the_irons2^5 = 32 [22:52]
mercutiotwo /21s make a /20 [22:52]
up_the_ironsah right, i forget about the 206.162.240.0/20 one [22:52]
mercutioso you have 3 /20s ? [22:52]
up_the_ironsso a /19 equivalent and one /20 [22:53]
mercutioyeah [22:53]
up_the_ironsso yeah, 48 /24's [22:53]
mercutioexcept they're not adjacent
so you can't advertise /19
[22:53]
up_the_ironsright [22:53]
mercutiostill that doesn't seem that expensive
but getting more may be difficult
[22:53]
up_the_ironsgetting more is difficult, yes [22:55]
mercutioand you're allocating a /30 per vps
so much more usage
but more protection
[22:55]
up_the_ironsyeah [22:59]
pcnup_the_irons I seem to have just re-installed 10.04 from the virtual CD. Did I mis-understand that 12.04 was in there? [23:02]
mercutioi'd imagine you didn't shutdown through the interface [23:03]
arenlorpcn: Did you hard shutdown and boot? [23:03]
up_the_ironspcn: it's in there, but you need to give it a hard shutdown and then boot, or else the changes do not take effect [23:03]
pcnAh, got it. My bad [23:04]
***HighJinx has joined #arpnetworks [23:04]
arenlorup_the_irons: How's the connection with comcast? [23:07]
up_the_ironsarenlor: wut [23:08]
arenlorup_the_irons: Do you peer with Comcast, or do they only give you a shitty connection? [23:08]
up_the_ironsarenlor: oh, i don't peer with Comcast. it would be great if i did :) [23:09]
mercutiomaybe just download the speed test? [23:09]
arenlormercutio: Don't have comcast yet. [23:09]
mercutiooh [23:09]
arenlorJust hoping that he would say something like, perfect 100% speed no matter what.
arenlor is still mad that Comcast is my great hope for fast stable internet.
[23:09]
mercutiotrace to www.comcast.net goes through mzima/glbx/qwest
oh hangon
that's akamai
?
mzima have direct peer with comcast
[23:10]
arenlorDoesn't comcast own akamai? [23:10]
mercutiooh?
i'm tracing to mx4.comcast.net
[23:10]
up_the_ironsmercutio: arenlor : mzima does have a comcast peer, I believe [23:13]
mercutio"We do not offer peering, paid or otherwise, on the shared fabric public switches at any IX.
"
they're at one wilshire way
but don't do peering on shared switches at least
they probably would want to charge to peer
[23:14]
arenlorHuh, seems Akamai isn't owned by anyone, thought they were. [23:14]
mercutioplus interconnect
and mzima having peer means it probably isn't worthwhile
[23:14]
up_the_ironsmercutio: the "shared fabric public switch" is the clincher there. They do peer, just not on the IX's, so you need a dedicated cross-connect to them. [23:16]
mercutiocomcast route server has ipv6 heh
up: it prob means they also want high traffic volumes
how doi tell traceroute on comcast's route server to do ipv4
[23:16]
arenlorprobably -4 [23:17]
mercutionope
tried that
it's traceroute ip www.arpnetworks.com
[23:18]
up_the_ironswhat's their route server ip / host? [23:18]
mercutiook basically it stays in comcast's network iwth fowrad and reverse traceroute
with direct peer with mzima in los angeles
route-server.newyork.ny.ibone.comcast.net
telnet
[23:18]
up_the_ironscool [23:20]
mercutioi think it's likely to be good to comcsat
comcast
but if it's bad it'll be bad to all comcast areas
[23:21]
arenlorNice ^_^ [23:22]
mercutioso if you get someone else on comcast to try it you can see what it's like [23:22]
arenlorarenlor gets depressed looking at the Baby Bell list [23:22]
up_the_ironsdang, earthquake [23:24]
arenlorup_the_irons: You're still online, it's cool. [23:24]
up_the_ironshaha [23:24]
mercutiomm
i've been in a earthquake big enough to take out internet
well actualyl i don't know if the internet went out or not, cos there wsa no power
[23:31]
arenlormercutio: I'd say the Internet went out then. [23:32]
mercutiobut with most earthquakes internet is fine
hmm
the power never came back
[23:32]
arenlormercutio: Not if your hub loses power. [23:32]
mercutiowell with one of them
yeh i had no ups
i was suprised the tv was fine
cos it fell onto the grnd
ground
and ocmputer monitor fell onto the ground behind my computer desk.
my computer desk was against the wall.
/was/ being the operative word
[23:33]
arenlormercutio: You from CC? [23:34]
mercutiocc? [23:34]
arenlorChrist Church [23:34]
mercutioyes
except it's one word
and i'm not christian
arenlor: how'd you know? :)
[23:34]
arenlormercutio: A friend of mine has family there (and she is originally from there) [23:35]
mercutiodid you get nes there?
news
ahh
i had to stay with my parents for a while.
[23:35]
arenlormercutio: Yeah, your dwelling livable or did you have to move? [23:35]
mercutioi had to move
i moved cities
rent prices have gone up there
ther'es still nowehre to drink
everyone's all depressed
and people talk about rebuild a lot
[23:36]
arenlormercutio: I'd have thought bars would be there by now. [23:36]
mercutioand earthquakes
they're still having aftershocks.
well, the bars were in central city. and central city got hit the hardest.
[23:36]
arenlormercutio: Yeah, I subscribe to a twitter feed on NZ earthquakes. [23:37]
mercutiothere are a few suburban bars, but they're ...
well, it's not the same.
like it was a city very much based around the center
centre
and when the centre goes
it feels kind of rather broken
[23:37]
arenlormercutio: Yeah. I just hope they manage to save some of the city. [23:38]
mercutiowell the suburbs aren't doing too bad.
i lived near the city
20 minutes walk to work
[23:38]
arenlorI keep hearing about more and more having to be deconstructed "for safety" [23:38]
mercutioit was a suburb
but like adjacent to the city centre
[23:38]
arenlormercutio: Awesomeness.
mercutio: I hope you didn't lose anything too important
[23:38]

i lost my old bbs computer :9
:(
but i hadn't got around to checking that out
i lost like an old sparc
[23:40]
up_the_ironshmmm... i wonder if using the network number as a valid (secondary) gateway IP for /30 assignments would be tolerable
"On the issue of using subnet zero and the all-ones subnet, RFC 1878 leavingcisco.com states, "This practice (of excluding all-zeros and all-ones subnets) is obsolete. Modern software will be able to utilize all definable networks." Today, the use of subnet zero and the all-ones subnet is generally accepted and most vendors support their use. However, on certain networks, particularly the ones
[23:40]
mercutioa bicycle [23:40]
up_the_ironsusing legacy software, the use of subnet zero and the all-ones subnet can lead to problems." [23:40]
mercutioup_the_irons: you can actually assign /31s now [23:40]
up_the_ironss/leavingcisco.com//
mercutio: yeah, just do point-to-point
hmmm
HRMMM
[23:41]
mercutioelectric guitar broken and stuff
but like that's only possessions :/
[23:41]
arenlormercutio: That sucks though. [23:41]
mercutioi more miss routine etc [23:41]
arenlorThat's true. [23:41]
mercutiolike all the regular food places i went to went away
umm
and living your parents when you're an adult sucks
and i went and looked at som eplaces
and there were HEAPS of people there
and the place sucked
and i'm like uhh...
how the hell do i move cities?
so i kind of focusedon that
it wasn't that hard
i managed to fit quite a lot of stuff in my car
but now i hardly know anyone and spend too much time online :/
[23:42]
arenlormercutio: It's fine, we do too. [23:44]
mercutioheh
up_the_irons: i had someon ewant to setup a /31 with me
and thought it was most bizzare
[23:44]
arenlormercutio: That feels dirty. [23:44]
mercutioand i asked someon eelse.. and had a look on the net
and it works a lot better than it used to apparently
arenlor: what does?
[23:44]
arenlormercutio: A /31 [23:45]
mercutiooh
that was my first thought
[23:45]
up_the_ironsmercutio: arenlor : turns out that as long as both sides agree to the /31, there really isn't much of a problem [23:45]
arenlorup_the_irons: Nice. I guess /31 will help with the IP crunch a bit. [23:46]
mercutioup_the_irons: well apparently cisco, juniper, openbsd, and linux are all fine with it
you may have problems with os/2 or windows
or other archaic systems
[23:46]
up_the_ironsarenlor: yeah [23:47]
mercutiobut that's likely to be very uncommon [23:47]
up_the_ironsmercutio: yep [23:47]
arenlorI always love talking about modern OSs and watching the realization dawn as people realize I'm discluding Windows in that statement. [23:48]
mercutioarenlor: hahaha
i suppose id id that
windows has dated network caode
code
it's got modern vm systems
although..
[23:48]
arenlorWindows has dated everything, that's why it has some many viruses. [23:48]
mercutioi was copying some files over network.. with multiple copies goiing at once
and disk latency lept up something chronic
and it didn't seem nearly as bad on the remote system
(this is with windows 8)
so i think windows is still pretty bad at getting block sizes sufficient to deal with sata disks
[23:48]
arenlormercutio: NTFS on the one with the issue, another file system on the other? [23:49]
mercutioarenlor: ntfs to zfs
both single spindles.
both seagate disks
3tb remote 1 tb source
[23:50]
arenlormercutio: NTFS is so damned old. [23:50]
mercutioarenlor: yeh
i kind of want to try btrfs sometime
and lz4 compression
[23:50]
arenlormercutio: Don't bother with btrfs yet. [23:50]
mercutiolz4 compression can basically go around 3 gigabytes/sec
on one cpu code
or soemthing crazy like that
so basically you're unlikely to be cpu bound by doing compression
and people are working at putting suppot for it into both zfs and btrfs
[23:51]
arenlorI'm sure ZFS will have it first [23:52]
mercutiozfs is kind of forking though.. cos of the whole sun/oracle transiition
i'm not sure about that
zfs is getting feature subsets though
so that you can have some features without all features
when it was just one version of zfs.. .you could just increment the version number
but when you have multiple forks you can't realy do that
[23:52]
arenlorNTFS is 19 years old :'( why do we still have it? [23:52]
mercutiobut that means that this feature flags thing is needed
arenlor: ufs is older.
[23:53]
arenlormercutio: I don't use UFS, do you? [23:53]
mercutioi use a derivitive [23:53]
arenlorStill, it's been improved upon. [23:53]
mercutioyeh
so has ntfs though
god you know the thing that bugs me the most about file systems is VFAT on usb sticks.
which can't support files bigger than 4gb.
so you kind of have to end up using ntfs :(
[23:53]
arenlorVFAT is stupid.
When was NTFS improved?
[23:54]
mercutioThe PlayStation 3 game console uses UFS2 on HDD.[citation needed] The PlayStation 2 HDD used UFS as well.[citation needed]
it's been improved with every new windows release
[23:55]
arenlormercutio: Really? I've never noticed any difference. [23:55]
mercutiotry using nt 3.5? [23:56]
arenlormercutio: That's too old even for me to have used.
I've only been around computers since 95 was out.
[23:56]
mercutioWhile the different NTFS versions are for the most part fully forward- and backward-compatible, there are technical considerations for mounting newer NTFS volumes in older versions of Microsoft Windows. This affects dual-booting, and external portable hard drives.
For example, attempting to use an NTFS partition with "Previous Versions" (a.k.a. Volume Shadow Copy) on an operating system that does not support it will result in the contents of those previous versions being lost.[39]
hmm
well i used to use hpfs386
[23:57]
up_the_ironsinteresting: [23:58]
mercutioand you could do wonderful write caching wtih that [23:58]
up_the_ironss1.lax(config-if)#ip address 174.136.96.0 255.255.255.254 secondary
% Warning: use /31 mask on non point-to-point interface cautiously
googling reveals that is an obsolete warning
[23:58]
mercutiohmm [23:58]
arenlorup_the_irons: Maybe it's meant to scare idiots away from doing something like that? [23:58]
up_the_ironsat first, i had a hard time assigning .0 to the interface.. it would say the mask is wrong
but figured i tout:
*it out:
ip address 174.136.96.0 255.255.255.254 secondary
[23:58]
mercutioyou have to enable something [23:59]
up_the_ironsip address 174.136.96.1 255.255.255.252 [23:59]
mercutiooh [23:59]
up_the_ironsso i have the .1 gateway and .0 assigned
mercutio: "ip subnet-zero" is already enabled; that is probably what you are thinking of
[23:59]
mercutioup_the_irons: ahh yip
up_the_irons: i kept thinking ip unnumbered and thinking it was something else :)
