m0undsup_the_irons: yeah, in the case of my pair of chassis, it's reserving for two additional supervisors, rather than just the standard single redundant sup
so...500W for one Sup2T, then reserving ~1000W for two more
I think it's a bug
also, yup, MX80 = 372W
also does N+1 PSUs rather than quasi-redundant power supplies like in cisco gear - they load share, and you can power the whole device off 3 PSUs, but there's also a fourth one in the chassis that serves as the +1
[06:54]
well, i guess not less than 350W (too early for me to be reading) but /close to/ 350W :) [07:08]

mnathaniAnyone know of a website that specializes in the storage, collection, archiving, search and retreival of scanned images and documents?
tagging functionality as well as folders / labels would also be handy

up_the_ironsm0unds: wow that's pretty cool of the MX80
up_the_irons looks for one on ebay
[12:28]
m0undsspec-wise, they're pretty impressive too [12:33]
.... (idle for 17mn)
i'd like to mess with more j gear, but every site i've worked with is 100% cisco
haha, only $40k for an MX480
"only"
jeez, for $40k, you can also get an EX8216 (16-slot EX8200 switch chassis) w/redundant PSUs, 3x 10GbE SFP+ line cards, 2x 48-port SFP line card and 2x 48 Port 10/100/1000 line cards

up_the_ironsyeah the pricing is always crazy, which is why i never have the opportunity to get a juniper [13:22]
m0undsjust need to find a tipped over delivery truck full of j stuff [13:24]
.... (idle for 15mn)
hazardouswont be hard
it's not like many people will be grabbing at stuff compared to an overturned alcohol truck or something
you could probably take the whole truck
[13:39]
m0undshahaha
and a couple guys to help you move stuff - those switch chassis' are heavy heavy heavy
[13:44]
up_the_ironsLOL
i actually found a 6506 chassis in a dumpster once. i grabbed it. ;) Never had the courage to use it cuz wtf, it could be garbage for real. had a big dent too, but could probably be hammered out.

mercutiom0unds: the J stuff isn't good for the modern internet [15:22]
m0undsmercutio: and i know tons of folks who work on huge modern networks who would disagree [15:22]
mercutioeven MX120 sucks with full convergence [15:23]
m0undsmax120 is tiny
mx120
[15:23]
mercutiojuniper don't have SMP support yet
adn use small cpus
cisco use small cpus too, but have more efficient bgp implementation
[15:23]
m0undsthey use appropriately specced cpus in their routing engines and other stuff
ask the folks who bought into nexus and ios xr how much fun that's been for them, haha
[15:23]
mercutiowell route tables are going to get bigger, and if you want to do things like rpki it uses more cpu
i dunno i use bsd :)
[15:24]
m0undsand how cisco's own engineering folks realized they screwed up and had to reengineer an old product (6500) and release that because their flagship line is pretty terrible
i don't think one datapoint makes something better or worse than something else
[15:24]
mercutiowell bgp convergence times are too long on the current internet
and with things like ddos attacks taking out transit links at times, or people just screwing up fibre connects, bgp convergence time is noticable.
[15:25]
m0undsalso, junos has supported SMP since 8.5, if their release notes are trustworthy [15:26]
mercutiocurious
mx120 has two cpus only one used from what i read
[15:27]
m0undsSMP support in the kernel was added in 8.5 via an upgrade to the kernel and control plane (freebsd) [15:29]
mercutiomaybe i thinking of mx80
i look eat list and i can't see 120
[15:30]
m0undslast time i see anyone mentioning of it not supporting SMP was in 2011 [15:30]
mercutiohttp://web.archiveorange.com/archive/v/M4zXgZAHIfCG3dgyuFF1 [15:30]
m0undsi'd check if i had an MX80 in front of me [15:30]
mercutioyeh i think it's mx80 i was thinking of [15:31]
***grepidemic has joined #arpnetworks [15:31]
mercutiowhich still arne't cheap [15:31]
m0undsthe bgp convergence issue was due to rpd, and according to jtac that was fixed in 11.4R7-S1 [15:33]
mercutiowhen was that? [15:33]
m0undssome weird blocking condition
looking
[15:33]
mercutioi think it's 2 or 3 minutes when not foobared
and 15minutes plus when foobared
but it means people are hesitant to use full route tables on them
[15:33]
m0undshaha, they still haven't fixed my juniper acct
march of 2013
[15:35]
mercutiothey also don't have reundant re [15:35]
m0undslarger chassis' do [15:36]
mercutioyeh [15:36]
m0undscan accommodate it anyway [15:36]
mercutiothen you have to pay for line cards [15:36]
m0undsyep [15:37]
mercutioand the cheap line cards don't do aqm
and the aqm line cards cost more
but i suppose networks is something poeople will invest in
[15:37]
m0undsyea, biggest capex here is networking equipment [15:37]
mercutioi do think they're overpriced in general
and maybe this sdn stuff will improve matters
[15:38]
m0undsi think a lot of the dedicated networking gear is way expensive
in some cases i think it's justified, and in others i think it's absurd
[15:38]
mercutiocos it'd be nicer to have a pc or such control the routing
and just tell the switch where to send stuff
i want to see more interconnects everywhere myself
like between providers local peering etc
which means terminating connections for local users close too
which means needing a router or something close too, whiich means people are likely to use smaller routers

mus1cb0xhttp://support.arpnetworks.com/kb/main/is-there-a-firewall-filter-rate-limit-or-similar-device-applied-to-my-traffic is great
"SSH rate-limit inbound on port 22 (VPS only)"
now i don't need to run fail2ban on my vps's
awesome that it's documented too
[17:29]
mhoranYep. [17:33]
mus1cb0xis it still good practice to run pf for basics such as filtering all port 22 access that doesn't come from my isp? [17:34]
***goodwill has joined #arpnetworks [17:45]
goodwillstupid question: is using something like this to cool the a server room/closet considered to be a sane way to do things: http://www.tripplite.com/sku/SRCOOL12K/

m0undsgoodwill: we use similar units as backup cooling (in the event that our chiller plant has issues) [19:00]
jpalmergoodwill: same as m0unds we have 3 of them. but they are for emergency/backup only. if you don't setup a permanent drain line, there is a "bucket" that catches the water. If yuo don't drain it often enough, it has a switch that kills the unit so you don't flood the server room. In florida, that bucket fills in under 8 hours. [19:04]

m0undsluckily, i'm in the desert and there's little to no condensate to drain, hahaha [19:24]

up_the_ironsm0unds: jpalmer : a lot of those units don't have the drain buckets anymore, they just evaporate it somehow [22:18]
m0undshuh.
we've got a big-ass backup AC for our server room - it has a garden hose-sized drain on it. i think it's like a 3 ton unit or something ridiculous like that. takes two people to move it, despite it being on wheels.
