brycec: It is. I consider myself quite good, which isn't very humble but it is apparently the case comparing my searches with others' ability to find relevant information quickly. mercutio: i consider myself quite bad, but i see people doing much worse than me :)
my problem is coming up with things that will uniquely anchor down on the information i want
i often end up with a lot of irrelevant stuff
often i give up on things i'm only casually interested in. brycec: That's exactly what I'm expert at - boiling it down to the key and unique facts. Works out in the real world too.
I think it's just how the brain is wired mercutio: like my friend upgraded his comcast connection speed, and my thinking is the modem tftp's a new config file for the higher speed; it seemed to only get half-upgraded. so i was curious about how the tftp system from the modem works..
but i found things about how to hack cable to get faster speeds from years back etc. brycec: heh, I remember that stuff :) mercutio: i remember being slightly interested in that stuff before, it was curious that you could get higher speeds by tftping your own config. brycec: And a lot of it is somewhat applicable... though Cable operators have tightened it down with config signing and the like. mercutio: but i wanted to find the legit way it worked, wondering if it was overnight for upgrades or what. brycec: like http://www.dslreports.com/faq/cabletech/5._Cable_Modems ?
(first result for HFC provisioning) -: brycec can tell you much more too, lots of experience mercutio: hmm it deosn't say anything about the upgrade process.
do you happen to know about that brycec? brycec: heh I only skimmed the faq
http://www.incognito.com/wp-content/uploads/device-provisioning-in-cable-environments.pdf gets into a bit more detail of the process
but still relatively high-level and easy to understand. mercutio: everyone knows blackblaze's hard-drive reliability testing isn't reliable.
but does anyone have any good source for hard-drive reliability by model? brycec: http://www.cisco.com/c/en/us/td/docs/ios/cable/configuration/guide/12_2sc/Cisco_CMTS_Router_Services/cmts_svcs_cnr.pdf will give you a bit more detail, at least as it pertains to configuration Cisco's headends, but the core information is the same across HFC.
(both results from the first page of "hfc provisioning tftp")
I can also confirm http://volpefirm.com/docsis101_modem-registration/ is valid, and has flow charts (and pop-in ads)
So that's how cable modems are configured... Whether *that* is what controls connection speed is a different story.
In the "early days" of cable modems, cable TV providers were new at the ISP game, were bad at QoS and fair-use, left most of the network *wide* open (yes, you could Samba fileshare with your neighbours! or, you could just scan their computers and steal their music), and for simplicity most seemed to use the modem's provisioning for speed control. ***: milki has joined #arpnetworks brycec: They've learned since then, slowly, and speed is no longer solely controlled by the modem's provisioning (if at all). The sync speed, number of channels to establish (and allowed to establish), as well as any burst/throttling rules can (and typically are) be enforced by the headend.
(The headend is basically the other modem at the end of the cable modem connection, for the unitiated.) mercutio: brycec: yeh i suspect he hasn't had his number of channels raised.
because download speed went up a bit, but not all the way..
and upload speed is still the same. brycec: Could also be limited by what his modem is capable of mercutio: and his modem was already docsis 3.
yeah his modem is on the list for plan speed. brycec: I've seen plenty of 4/4 modems
Heh then yeah it should support it. mercutio: this is 8 brycec: Good. (Mine is too :) )
*8/4) mercutio: it said up to 300 megabit or something brycec: (which is just quoting Docsis3 IIRC :p) mercutio: heh
docsis 3.1 is meant to give some more improvements. brycec: (Thank you Wikipedia for breaking it down - yep, to reach 300mbps requires 8 channels, so if his says it can do that...) mercutio: he's getting like 90 megabit
on 150 plan
maybe that's 3 channels? brycec: Or his node is congested... mercutio: it's consistent though brycec: http://speedtest.comcast.net/ is handy (if he's on Comcast) mercutio: more channels should still help if it's congested. brycec: If that isn't your plan speed (consistently), then you get to bitch at Comcast :) mercutio: yeah brycec: (whereas if you take speedtest.net to them, they laugh and point at the fine print) mercutio: i've had no experience at such
but from what i read, it doesn't sound like much fun. brycec: Dumb question - does he have >100mbps from computer to modem? mercutio: yeh brycec: (eg: no wifi, etc) mercutio: well it's also uploading at 6 megabit brycec: which is way less than 1 channel upload ;) mercutio: you know, his 25 megabit plan went at 30 megabit brycec: so that makes it sound like the problem is on his side -: brycec blames wifi ***: LT has joined #arpnetworks mercutio: so if he was on 50 megabit plan it'd probably go at 60 megabit brycec: (and the defacto test: plug a laptop directly into the modem and test) mercutio: so 150 would go at 180 megabit brycec: heh mercutio: so it's going at half the speed
btu maybe they triple osmething to go from 50 to 150...
and thoght he was on 50... when he was on 25. brycec: Sometimes I seriously consider running cable to my cable modem... it sucks that I'm limited to 100mbps (out of 120) because of the moca adapters mercutio: 100 megabit can be faster than gigabit. brycec: (but then again, I'm happy enough with 100... that's just plain blazin to me) mercutio: basically 100 megabit with serialisation delay can mean that you hit real 100 megabit better/easier/more consistently
whereas when it hits gigabit it can think your line speed is faster and drop stuff
it depends if there are lame policers and a higher link speed or not.
there's new fibre stuff here and they have god-awful policers.
and it means international speed can be bad with some providers. brycec: Hm good points mercutio: whereas national will "speed test" fine to a close location.
it's complicated, because you need really good granuality to deal with the strict policer.
from what i've heard linux's isn't very good for it.
i think linux operates per msec.
so if you have 200 megabit... that's 24000k, and 24000/1000 is 24k...
so sending 24k at a time is bad...
i wonder what their burst is set to, maybe 3k or something stupid :/
also linux doesn't offically support HZ > 1000 ***: Seji has quit IRC (Remote host closed the connection)

i stopped using it after getting it going basically though
i did two of them even
i used the first one for a bit longer..
i have been wondering about doing another, because i have a spare monitor, and synergy supports os x..
the first time around i went with name brand hardware so that i'd know it'd easily install, but it was kind of sluggish.
the second time i did old p67 board with ati video brycec: I ended up just running OSX in VM as needed (or on the one mac I have) mercutio: my mac didn't work with current software
because it was g4 brycec: lol yeah, support for macppc was dropped years ago ;) mercutio: it was years ago i did it
2010 i think brycec: My G4s are from 2003 and 2001 :D
(er, 2000) mnathani_: I used to own a macbook pro
and also a mac mini
but no longer BryceBot: That's what she said!! mercutio: this was mac mini g4 mnathani_: BryceBot: no BryceBot: Oh, okay... I'm sorry. 'but no longer' mnathani_: my Mac Mini was intel
probably ran windows on it for the most part using bootcamp -: brycec has owned both intel and g4 mac minis mercutio: mine struggled with 1920x1200 mnathani_: @google time in auckland BryceBot: 8,680,000 total results returned for 'time in auckland', here's 3

but i call it -8/-5
plus a day
it's just easier to change by 5 or 8 hours
so it's 10:46 am here, 15:46 am west coast, 18:46 east coast.
well 3:46 pm :) brycec: LOL "15:46 am" mercutio: well i think 15:46 am makes sense at least :)
oh it doesn't
it means before noon :)
i think of it as after midnight :)
whenever i go between morning / afternoon i tend to use 24 hour time, but if it's before i say am so it's known that it's morning mnathani: @google nba BryceBot: 52,700,000 total results returned for 'nba', here's 3

presently it is only 9 hops
via gtt
used to be more hops via he.net mercutio: hops isn't everything
gtt may have removed an ASN in their path
it's nlayer/tinet/gtt/mzima etc mnathani_: http://imgur.com/OPJJ5cz
this is why you don't use Windows to run your ATMS Royal Bank! mercutio: nice and cryptic
what's with the funny lookng guy
is that postman pat? brycec: It's RBC's character
Just a dumb avatar mercutio: who just happens to look like postman pat? brycec: I wouldn't know. mnathani_: is network manager supposed to be straightforward?
I am having issues connecting to wifi using arch / kde / networkmanager
command line wifi-menu worked just fine though mercutio: just use command line
i use wictl
or whatever
wlctl?
the "other" one brycec: mercutio: wicd?
(which has wicd-gtk, I might add)
NM was straight-forward for me. Install, enable systemd service, and launch nm-applet mnathani_: what desktop environment brycec? brycec: Awesome
(Which is technically a WM, not a DE, I know) mercutio: that could be it
i was only using it to play with
i normally configure netowrk stuff manually mnathani_: I hate it when a reboot fixes an issue mercutio: same mnathani_: specifically on linux mercutio: i try to figure otu what's happening first mnathani_: only kernel updates should need a reboot mercutio: i hardly ever find rebooting fixes an issue brycec: lol mnathani_ mercutio: here people always to turn your rouuter on/off
when it never helps
and often means you get net back slower
mnathani_: 4.1 is fixing that brycec: (Or changes to the system's init - that would also sorta require a reboot, barring kexec juggling) mercutio: rebootless patching
it's going to be supported long term by someone called ltsi
long term support initiative?
a lot of windows people have a strong mantra about rebooting
web server isn't responding, reboot! brycec: Many times a reboot is the simplest/quickest resolution, especially when you're trying to guide someone else through it mercutio: it means you can't stop it happening again
it used to be kind of useful when swapping hard
but that doesn't really happen anymore. brycec: I'm just speaking from experience as a level 1 tech - wasn't scripted or anything, but it was known that if you can't fix the issue quick (and depending on the customer's disposition), you fall back to a reboot and hope that fixes it. The customer doesn't usually care about the "why" they just want to be fixed and running again. mercutio: yeh it did used to help a bit
on 4mb, 8mb etc routers which would have processes die
or hit memory limits on nat connections or such
i haven't found it necesary in ages though
