most run off heartinternet (or resellers of) - using a shakey ass rig of hardware and networks

mnathani_: whats up with that image?
doesnt look like networking gear to me
m0unds: that's why i linked it
because funny
brocade blows
old foundry stuff was good enough, new brocade stuff is yucky
***: MrMorden has quit IRC (Read error: Connection reset by peer)
kellytk: grody: Why would UK lack quality providers?
staticsafe: UK has plenty of good providers
and stuff in London is usually well connected to both mainland Europe and USA
hazardous: goscomb and bytemark have been good to me
heart internet is like, mm
the UK equivalent of EIG i guess
mercutio: EIG?
this tame systemcall thing on openbsd suonds interesting
grody: kellytk, oh they don't lack them.. but most of the ones you find by google are by far from the best
a lot are just resellers of platforms already in place
mercutio: well vultr's issue in uk seems to be that they're single homed with level3
i dunno why level3 would have a big issue though?
grody: quite a large provider
mercutio: vultr has quite a few random outages actually
grody: ovh are quite nice for VPS
mercutio: well i'm not doing anything that important with it
just smokeping and as an external host to check connectivy/speed/blah
but the loss levels were insane
grody: oddly, even though ARP is quite a distance, i use it for a lot of personal stuff simply because it's reliable
even now ircing from it, the latency of the echo over ssh is more than acceptable
but A&A > ARP has a nice fast route
AA > NTT > ARP
same on 4 & 6
mike-burns: I'm 60% of the way through reading the tame(2) diff, and I like what I see. Rather excited about the changes to ps(1), silly as that sounds.
mercutio: i get pretty consistent latency to arp too. but for irc i ssh to somewhere 5 msec away :)
kellytk: mike-burns: What kind of changes to ps are you seeing?
mike-burns: It prints whether the process has been tamed.
kellytk: I'm not finding a man page on tame. Do you have a link handy?

BryceBot: openbsd-tech: "tame(2) WIP" from Theo de Raadt <deraadt () cvs ! openbsd ! org> @ 2015-07-18 22:50:27
mercutio: there was an e-mail today about it
so "bleeding edge"
mike-burns: Definitely WIP. It even includes commented-out code using // comments.
mercutio: a nice concept though
kellytk: mike-burns: That's a nice read, thank you
mercutio: apparently "doas" hit the tree recently too
mike-burns: I suspect that I won't be able to use tame(2) in my GTK+ apps.
I'm going to use sudo(1) until 5.9 or 6.0, methinks.
mercutio: the next openbsd is in november right?
kellytk: I support both capabilities as well as relinquishing them
mercutio: i used to use a program called tame with dos
mike-burns: November seems right.
mercutio: it would help give up time slices to "hogging" applications
kellytk: I used to tame in UO, although that's a different context entirely
mercutio: lots of dos software used to poll for key presses.
it was kind of ick
some even did things like write character, check keyboard, write character, check keyboard
so if you tamed them and it saw there were a lot of keystrokes and gave up time slice, it'd slow the character writing down :(
kellytk: Shameful
mike-burns: It was a limited OS.
mercutio: true, but writing characters to the screen one character at a time seems like a bad idea in any context.
actually that's probably a lot less inefficient these days..
mike-burns: This is nearly as exciting as sed(1) taking a -i option.
mercutio: curl does a whole lot of that for ui stuff and you don't reall ynotice
how long has sed had -i?
mike-burns: Two days?
mercutio: sed -i is basically like the replace program?
mike-burns: Yeah.
mercutio: sweet
well linux already has it :)
mike-burns: Not even two days: 27 hours, according to CVS.
mercutio: i wonder if freebsd does
it may be possible to start using it regularly :)
mike-burns: I think it does.
IIRC, OBSD was inspired by FBSD.
mercutio: freebsd 9 does too
woot
mike-burns: http://marc.info/?l=openbsd-tech&m=143714951126397&w=2 - the thread.
BryceBot: openbsd-tech: "sed -i" from Jasper Lievisse Adriaanse <jasper () openbsd ! org> @ 2015-07-17 16:10:46
mercutio: hmm openbsd doesn't have the replace command
mike-burns: I've no idea what the replace command is.
I just said "yeah" when you mentioned it because hey why not.
mercutio: hmm it comes from mysql-server
maybe this is a different one than i remember
mike-burns: https://dev.mysql.com/doc/refman/5.0/en/replace-utility.html - ?
mercutio: it's basically like sed -i
but this mysql one seems different
i usually just use two files myself
mike-burns: We'll have to continue that for a long while, I fear.
mercutio: i hardly ever use egrep even
sometimes it's easier to just keep things simple, even if it's more drawn out..
userauth_pubkey: key type ssh-dss not in PubkeyAcceptedKeyTypes
hmm openbsd stopped allowing dss keys
-: mercutio probably should have read the upgrade changelog :)
mercutio: so dss isn't supported by default, but ecdsa works these days
i wonder if they decided dsa was insecure
grody: interesting.. just cottoned on the intel dual port nic in my pfsense supports some microcode loading
and it appears to dramatically reduce interupt requests
mercutio: yeh there are firmware blobs for broadcom/intel ethernet cards
that handle coalescing etc.
you can adjust coalescing levels too
generally speaking it helps a lot less at 100 megabit than gigabit if you want to have "reasonable" latency
err for bulk throughput - it can still help ddos type things i suppose
but with adsl/vdsl loads you kind of want to interrupt for every packet
well every packet received, not transmitted packets..
it's one of the instances, where higher speed links can use less cpu - as coalescing can work better
grody: well one is for the WAN port, the other has a few VLAN networks routed via it and does hit high duplex loads
mercutio: intel is wan, non-intel lan?
wan < 100 megabit, lan gigabit?
i'd swap the cards around
grody: dual port intel, one port for WAN the other port for LAN (and a couple of VLANs)
mercutio: ahh
i see
1000pt?
grody: LAN or VLAN to VLAN can get quite high in load sometimes (i do have a second router for when i want faster)
not yet
mercutio: err card type i meant
grody: card is 100
mercutio: oh?
grody: upto 400mbps
havent got the new rig in yet
mercutio: http://www.intel.com/content/www/us/en/ethernet-products/gigabit-server-adapters/pro-1000-pt-dp.html
those cards are ultra cheap on ebay
grody: ahh the new rig has an e1000 1gbit dual port and a single port intel gigabit
mercutio: getting a bit old now, a bit higher power uage.
lots of the older dual intel cards are the pt ones
grody: just having some teething issues with it
mercutio: chip number is like 82571 or something
grody: yea, this thing is quite old
mercutio: probably intel pt, they're pretty stable
when i say higher power usage, it's TDP is only 3.43watts :)
so it's not high high
grody: 18.80% [intr{irq10: fxp0 vr0+}] | 11.18% [intr{irq11: fxp1 uhci}] - fxp0 is LAN facer and fxp1 WAN facer, thats with a combined 74mbps passing via the thing in whole
err, 54mbps*
mercutio: but you're upgrading to your newer box?
grody: soon, got to fix a few "issues"
mercutio: the fxp cards are pretty good for half duplex performance fwiw
they're more aggressive than other cards
grody: running a complete overhaul (may as well) and have a few cable shortage issues and it's not really econmical to run more
need a gigabit smart switch in each room with my new plans - and they're not exactly cheap
mercutio: you can get soem semi smart tp-links really cheap
like $25 US
they do vlans, bonding etc.
grody: http://goo.gl/h4GA6r
BryceBot: http://goo.gl/h4GA6r -> http://www.ebay.co.uk/itm/D-Link-DGS-1100-08-8-Port-Gigabit-Smart-Switch-/381254509365?pt=LH_DefaultDomain_3&hash=item58c48a2335
mercutio: but you have to use a special windows program to configure them. no web ui or serial or ssh or anything
grody: something like that
mercutio: fanless too.
grody: small, desktop like but smart
mercutio: i've been tempted to try one. i wish didn't have to use windows to configure though
grody: yea sod that :)
mercutio: these were like $25 US new
grody: one cable in.. multiple networks available
biggest flaw in my network was the access to my main network just by plugging in a cable into almost any port on any switch (in rooms)
mercutio: can you configure these with webui?
grody: yea
mercutio: serial?
ssh?
grody: i have zyxel version of these, but only 100
erm.. no idea
mercutio: GS105Ev2
hmm iwonder what that's like
hmm apparently recent firmware added webui
but it's way more expensive than tp-link
i wonder if tp-link have added webui.
grody: their high end switches do

grody: i had the odd pleasure of seeing an almost pure TP-Link home rig the other week
he says it's rock solid
mercutio: i don't /like/ tp-link but i find their stuff seems to be better than d-link and netgear and the like
and yet it's cheaper
grody: hmm
mercutio: also they seem to be pretty quick to do things like reduce power consumption
grody: for wifi equipment definately
they use qcom/ath
mercutio: for switches too
grody: yea
mercutio: i'm using tp-link access router
grody: a lot of my stuff here is tp-link
mercutio: this 8 port switch says 6.4 watts
i was using tp-link adsl modem
grody: my old main router and wifi AP were tp-link, both replaced with this single tp-link
mercutio: i'm using an "edgecore" switch
grody: tp-link for my shared wifi hotspot
mercutio: which is also fanless. 24+2
i compared fibre latency to copper
seems much the same
grody: i actually have no managed switch per-se atm
using port management off a couple of tp-link routers as smart switches dropping into uplinks
mercutio: this switch is ok, but you need to enable pause frames for it to deal with multiple ports going to one port
err flow control
i kind of wish i could find a cheap switch that does sfp+
it kind of seems silly to run 10 gigabit cards at gigabit
grody: i doubt i ever have that need
i barely flatten 100mbps
even put off upgrading to gbit until recently (slowly) - but thats only because i intend on getting a second vDSL
mercutio: well it's useful if you use hard-disk over network
and even more useful when you use ssd over network
but yeah gigabit would be fine :)
grody: it is bizarre.. used to remember running a NAT router on dialup to share the internet with a couple of hosts and alwats quizzed almost every packet coming in and out (on the modem light)
and now, just running tcpdump on the router there is this bombardment of various traffic
mercutio: haha
i have so many pings
bloody smokeping
hmm 47 pps
ok it seemed like a lot :)
grody: 279/30
oh wait.. thats my ARP
193444/30
will probably delegate this thing to my OpenVPN router when i rebuild
it can cope with quite a bit of traffic from it in this scenario.. if it was /just/ for openvpn..
193444 packets received by filter
191240 packets dropped by kernel
hah
poor thing
mnathani_: whats the page with top tech news?
mercutio: news.arpnetworks.com?
if not that i have no idea what you mean :)
mnathani_: that was one of them
brycec mentioned another I think it was when linode was switching to kvm or something
grody: hah sweet, i have a wifi network now using my ARP VPS as it's DHCP server and router
mercutio: grody: that's just weird :/
grody: i got bored after i added 3G failover
mercutio: what happens if your net goes down? :)
grody: well, that wifi network wont work
the others will though
mercutio: well at least you have 3g
oh hmm
i hate it how my cellphone won't go to 3g from wifi if there's no internet
mnathani_: thats the one > https://lobste.rs/
mercutio: that would solve that issue :)
grody: just thought "whats the easiest way to appear from the US.."
so i simply bridged a gif into pfsense LAN and a VAP into the gif linking with ARP
my phone has "avoid poor connections" - which drops a wifi poorly performing
mercutio: on android?
grody: yea
mercutio: mine doesn't that i've seen
grody: seems to work for the most part.. if i kill the gateway, it notices after about a minute
mercutio: i wish you could do both at once
grody: disconnects and disables using it for a while
mercutio: with seemless fallover
like be on a wifi call and shift to 3g
grody: i have aggressive wifi to 3g handover too
ah yea that would be nice
mercutio: i can't check my mail if i make a call on wifi
grody: that just drops weaker wifi sooner
mercutio: but i can go about a metre from the letterbox
maybe it's better now
i don't want to put my phone down to check mail
grody: i have an AP with an external antenna on my satelite dish
mercutio: but sometimes i want to check the mail while i'm on the phone, ... as i tend to like walking while i talk
grody: it just reaches the pub on the corner garden
US homes tends to be larger, harder to cover with standard indoor kit
(or are you NZ)
flip.. need to drop the PPPoE to (shift routing) test this
and i really cba.. will wait til it breaks
policy routing works over it (fun watching a packet going out 3G and return in FTTC)
mercutio: heh i drop heaps of signal going one room over
i reckon it's my house
i'm in nz
i hear that some kind of metal mesh stuff is common in the US that screws with wifi too
kellytk: mercutio: Is your home stone or stick-built?
mercutio: stick? :)
grody: when i peeled the wallpaper to paint the walls, the paper had aluminium foil inside it (some insulation thing, but also caused moulding) which deflected radio waves of all kinds
mercutio: it's wooden but i think there's metal supporting beams.
kellytk: Wood
grody: 3G peformance was poor in here befoe that
mercutio: yeh 3g is bad here too
but it's not great outside either
i think tower must be a way away
weird it's better than normal -7dbm
-75dbm
it's usualy more like -90 to -100dbm i thought
-85 dbm now, that's a huge jump
grody: my ping times to ARP are twice as good as my ping times over 3G
mercutio: your nexthop ping times on 3g, or 3g ping times to arp?
grody: 323.4ms on 3G 170.2ms to ARP
mercutio: ahh
i'm ~140ms to arp
grody: admitedly, the modem idles on UTMS until a certain data rate flows through it, then it goes HSPA and pings drop to about 50ms
mercutio: ahh
that sounds annoying
grody: it is
mercutio: mine stays on H
although it can do E occasaionally
and it can do lte when i'm not at home
grody: i wont even tell you pings on G/E here
average is over 1s
shwing.. i now have it so i can just alter routes (or dedicate US only IP ranges) to default route over the GIF to ARP, regardless of my IP and it be NAT on the ARP :D
on which note, i can go to bed (and wake up to it all broken)
kellytk: Suggestions for the name of a web host which is generic, does not exist, and would be clearly representative of a host? "Acme Hosting" is, unfortunately, an actual host
"Example" is a little dry
