HighJinx has joined #arpnetworks mnathani: what good is a Serial port available over SSH for server management? plett: mnathani: Very good, in my experience mnathani: how would one use it? plett: You would ssh to somewhere which isn't your server and get yourself connected to the serial console of your server mnathani: would that be kind of like a kvm? plett: I 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 ***: [FBI] starts logging #arpnetworks at Tue Aug 07 03:25:41 2012

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.

lteo has joined #arpnetworks tooth: yeah, i've done that at a few jobs
what I want is to receive sms and voice calls at the same numner andol: up_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.) up_the_irons: andol: 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) mercutio: unbound is nice :) plett: Yes, unbound is much nicer than bind. I use anycasted unbound servers for customer facing resolvers up_the_irons: nice ***: ziyourenxiang has joined #arpnetworks
ziyourenxiang has quit IRC (Quit: ziyourenxiang) mercutio: well 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 tooth: i'm using NSD myself ***: Webhostbudd_ has joined #arpnetworks mercutio: i didn't realise nsd did recursive?
unbound only does recursive
i use tinydns for authorative tooth: nsd only does authoritative. twobitha1ker: unbound can do some auth mercutio: two: 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 twobitha1ker: local-zone stuff in the config mercutio: it even makes windows default host names pingable :) twobitha1ker: I just recently switched my home router to dnsmasq, it is pretty slick mercutio: from 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 plett: I 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 jdoe: I'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 plett: It can be automated, but yes jdoe: with what registrar? 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) ***: heavysixer has quit IRC (Remote host closed the connection)

HighJinx has joined #arpnetworks jpalmer: up_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. toddf: jpalmer: 30 different data centers? thats some asset allocation scheme you're pushing there. up_the_irons: jpalmer: wow, cool :) jpalmer: toddf: 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. toddf: openvpn 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? jdoe: it'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. arenlor: For anyone who has a printer: http://www.youtube.com/watch?v=uZ1QMRRg__E ***: Webhostbudd_ has quit IRC (Quit: Leaving) ryk: i don't seem to be able to vnc into my console through either method (tunnelling or direct)

"Connecting..." arenlor: ryk: What client? ryk: chicken.app, worked for this vps in the past. arenlor: Never heard of it, was going to see if I had it somewhere.
Got another VPS to try? ryk: it's a fork from chicken of the vnc arenlor: You rememered to enter the correct port I'm assuming? ryk: yeah, 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 arenlor: ryk: You can submit them at any time. ryk: i 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 arenlor: ryk: It seems to be working for me so far. ryk: ok, thanks. arenlor: ryk: What host are you on? ryk: kvr19
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. arenlor: ryk: Yeah. Did it die maybe? ryk: it definitely didn't, because the serial console puts me at a login prompt

i was looking as the ssh command at the local port
so that suggests that the kvr19 host itself is not listening ***: portertech has left arenlor: ryk: It would seem so. ryk: I wasn't getting tripped up by the console server. that's only an ssh server used to bounce in

interesting mercutio: yeh, but why's it happening :) ***: HighJinx has quit IRC (Quit: Computer has gone to sleep.) mercutio: i had some stalls on em driver, before, using a more recent kernel seemed to help

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 awyeah: hrm, time to freebsd-update mercutio: http://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.
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

i lived near the city
20 minutes walk to work arenlor: I keep hearing about more and more having to be deconstructed "for safety" mercutio: it was a suburb
but like adjacent to the city centre arenlor: mercutio: Awesomeness.
mercutio: I hope you didn't lose anything too important mercutio: https://maps.google.co.nz/maps?q=merivale&hl=en&ll=-43.519277,172.625045&spn=0.000964,0.002025&safe=off&hnear=Merivale,+Christchurch,+Canterbury&gl=nz&t=h&z=20
i lost my old bbs computer :9
:(
but i hadn't got around to checking that out
i lost like an old sparc up_the_irons: hmmm... 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 mercutio: a bicycle up_the_irons: using legacy software, the use of subnet zero and the all-ones subnet can lead to problems." mercutio: up_the_irons: you can actually assign /31s now up_the_irons: s/leavingcisco.com//
mercutio: yeah, just do point-to-point
hmmm
HRMMM mercutio: electric guitar broken and stuff
but like that's only possessions :/ arenlor: mercutio: That sucks though. mercutio: i more miss routine etc arenlor: That's true. mercutio: like 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 :/ arenlor: mercutio: It's fine, we do too. mercutio: heh
up_the_irons: i had someon ewant to setup a /31 with me
and thought it was most bizzare arenlor: mercutio: That feels dirty. mercutio: and 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? arenlor: mercutio: A /31 mercutio: oh
that was my first thought up_the_irons: mercutio: arenlor : turns out that as long as both sides agree to the /31, there really isn't much of a problem arenlor: up_the_irons: Nice. I guess /31 will help with the IP crunch a bit. mercutio: up_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 up_the_irons: arenlor: yeah mercutio: but that's likely to be very uncommon up_the_irons: mercutio: yep arenlor: I always love talking about modern OSs and watching the realization dawn as people realize I'm discluding Windows in that statement. mercutio: arenlor: hahaha
i suppose id id that
windows has dated network caode
code
it's got modern vm systems
although.. arenlor: Windows has dated everything, that's why it has some many viruses. mercutio: i 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 arenlor: mercutio: NTFS on the one with the issue, another file system on the other? mercutio: arenlor: ntfs to zfs
both single spindles.
both seagate disks
3tb remote 1 tb source arenlor: mercutio: NTFS is so damned old. mercutio: arenlor: yeh
i kind of want to try btrfs sometime
and lz4 compression arenlor: mercutio: Don't bother with btrfs yet. mercutio: lz4 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 arenlor: I'm sure ZFS will have it first mercutio: zfs 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 arenlor: NTFS is 19 years old :'( why do we still have it? mercutio: but that means that this feature flags thing is needed
arenlor: ufs is older. arenlor: mercutio: I don't use UFS, do you? mercutio: i use a derivitive arenlor: Still, it's been improved upon. mercutio: yeh
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 :( arenlor: VFAT is stupid.
When was NTFS improved? mercutio: The 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 arenlor: mercutio: Really? I've never noticed any difference. mercutio: try using nt 3.5? arenlor: mercutio: That's too old even for me to have used.
I've only been around computers since 95 was out. mercutio: While 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 up_the_irons: interesting: mercutio: and you could do wonderful write caching wtih that up_the_irons: s1.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 mercutio: hmm arenlor: up_the_irons: Maybe it's meant to scare idiots away from doing something like that? up_the_irons: at 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 mercutio: you have to enable something up_the_irons: ip address 174.136.96.1 255.255.255.252 mercutio: oh up_the_irons: so i have the .1 gateway and .0 assigned
mercutio: "ip subnet-zero" is already enabled; that is probably what you are thinking of mercutio: up_the_irons: ahh yip
up_the_irons: i kept thinking ip unnumbered and thinking it was something else :)
