qbithuh, the vnc stuff seems to have stopped working on my vps
mid upgrade
via an ssh tunnel
telnet: connect to address 208.79.88.89: Connection refused
when i try to connect direclty
brycec: can you confirm :D ?

[08:56]
brycecThat usually indicates that your kvm process has crashed
though vinagre is bombing out vnc'ing to mine
but obviously it's still up
qbit: can you at least hit the the serial server?
[09:07]
qbitbrycec: i can hit the vnc port on other servers, and i am on console
kvr24.arpnetworks.com isn't letting me vnc
it did, then disconnected me mid upgrade
and now i can't reconnect
[09:09]
brycecodd...
Okay now that I'm back at a computer... qbit, I can hit vnc on two different VPS, but neither are on kvr24 :p
[09:23]
up_the_ironsqbit: sounds like your kvm process crashed (like brycec said). Hit Boot from the Portal and then see if you can connect [09:28]
brycecI could also hit qbit's vnc port, but only after 3 tries. The first two tries, TigerVNC gave a really useless error "CConn: No useful address for host" (even though DNS is fine)
up_the_irons: see update
[09:28]
qbiti am back on
thanks

mercutiodamn this new "zstd" compression is fast.
it's faster at compressing than xz is at decompressing.
with similar compression levels to gzip.

brycec"219,904,000 108M/s in 1.9s" I do enjoy having that GbE connection :D
(on my ARP Metal box)
[19:01]
.... (idle for 15mn)
mercutioheh where's that from [19:16]
brycecFrom mirrors.arp ;) [19:17]
mercutioheh [19:17]
brycecCan you guess the ISO? [19:17]
mercutioopenbsd
it's kind of obvious
considering the openbsd iso is about that size
[19:17]
brycec:D
I was hoping you'd guess which iso specifically, but whatever you win
[19:17]
mercutioamd64 install58.iso
in-tuh-resting
[19:18]
brycecyay [19:19]
mercutiothe iso says 220M in apache
but 220*1024*1024 is 230686720
Length: 230862848 (220M) [application/x-iso9660-image]
soo...
am i wrong?
ohhh
you're getting i386
are you using some ancient computers
[19:19]
brycechm could be, I grabbed both i386 and amd64 [19:22]
mercutiook
syou referenced the i386 one :)
[19:22]
brycecI guess I did, window's already closed :p [19:22]
mercutiook so i was right before i got more specific :) [19:22]
brycecoh btw, was looking at someone's VPS on kvr24 this morning - Is that box not getting the new/improved SeaBIOS you compiled, mercutio ? [19:25]
mercutiowhat do you mean?
i haven't pushed the cosmetic update still
if there's some pressing reason to do a seabios update it'll be ready though :)
[19:25]
brycecThe version string for SeaBIOS looked old and didn't show any "compiled by" string
So not even the pre-cosmetic update version.
No big deal, just curious.
(All I recall was "SeaBIOS 1.3..." but no user@buildhost or anything)
[19:25]
mercutiooh right
yeah there's two versions of seabios
there's the "old" hosts and the "new" hosts.
and only the new hosts have my seabios version on them.
[19:27]
brycecdo you mean "guest" or do you mean host machines? [19:27]
mercutiohost machines. [19:28]
brycecHigher numbers != "newer" is always confusing :) [19:28]
mercutioso yeah kvr24 has older host OS
precise vs trusty.
but precise is still supported for lts.
[19:28]
brycecI thought up_the_irons had finished all those upgrades by now
(I thought wrong, evidently)
[19:29]
mercutioheh
yeah there's quite a few precise hosts out there.
the precise hosts had fixes for venom.
but yeah having everything on trusty would be nice.
of course in 6 months time there'll be a new lts :)
[19:29]
...... (idle for 27mn)
brycechuzzah, I spent way more time than I should have today updating my smokeping targets :D and then it only took ~5 minutes to bring up another slave instance.
*and* I'm now monitoring dns resolution time and http response time for a few hosts! (after accidentally ddos'ing one host by hammering a slow-to-load page)
[19:58]
mercutiobrycec: have you seen ipv4 improvement?
http response time can be nice to do
[19:59]
brycecthis just leaves figuring out why one of the slaves stopped showing up even though I see its POSTs in the master's log... [19:59]
mercutios/ipv4/ipv6/ [19:59]
brycecmercutio: improvement relative to what? [19:59]
BryceBot<mercutio> brycec: have you seen ipv6 improvement? [19:59]
mercutiogrr
less loss
[19:59]
brycecoh that ipv6 thing a few weeks back?
I suppose I have
[20:00]
mercutiocool
i should clean up my smokepings :)
[20:00]
brycecI broke mine out into separate files too :) [20:00]
mercutioi've been playing with linux 4.3 prereleases
it seems to improve http download tests.
[20:00]
brycec(as it had reached ~1000 lines before I diddled with it today) [20:01]
mercutiothere's some change to congestion avoidance i think [20:01]
brycecLast 6mos of IPv6 shows a "bad time" and improvement since then https://smokeping.cobryce.com/?displaymode=n;start=2015-04-23%2019:58;end=now;target=ARP.ARPWebsite.ARPWebsite6 [20:02]
mnathani_Darn Teksavvy packet loss: Packets: Sent = 16, Received = 10, Lost = 6 (37% loss),
calling them simply leads to basic troubleshooting - 1.) connect PC directly to modem (disconnecting all other devices on the network) 2.) test network connectivity 3.) realize its actually the internet connection and not the router
[20:13]
mercutiomnathani_: is that cable?
it may b a physical problem
[20:27]
mnathani_yes, cable
problem is intermittent - usually between 11pm and 1am
my guess would be its the BRAS as mentioned before
[20:30]
brycec(HFC if you want to be technical ;) ) [20:31]
mercutioyeah 11pm and 1 am is peak usage time for uhh students
do you live in a student area? :)
of course it could vary around the world
but here internet usage tends to drop off around 11 pm
anyway the usual solution is they split your cable node into two nodes.
i wouldn't be surpriesd if it's one really heavy neighbour creating the bulk of the issues :/
there's been this tendency to start boosting cable speeds by using more channels at once.
but if there are still docsis 2 users on the network as well as docsis 3, then they can get more network bandwidth if they upgrade people to docsis 3
and by "most of the issues" i mean using a sizable chunk to bring it to sudden congestion.
[20:33]
heh apparently docsis 3 supports 32 channel bonding
i think 8 is common
with the 150 or whatever megabit plans
[20:43]
mnathani_: wikipedia suggests that teksavvy hav bw caps, and unlimited nights
maybe people are starting large downloads late at night?
[20:48]
mnathani_2am - 6am is unlimited I think? [20:53]
brycecAs someone who downloaded 82GB in Steam content just today, bw caps feel barbaric. [20:56]
mnathani_brycec: can I put you down as a reference for my devio.us application? [20:57]
brycecmnathani_: yes [20:57]
mnathani_cool
thanks
[20:57]
brycecmainly because it's not a "reference" it's just "who's going to remember talking to you"
to rephrase that, "Prove to us you actually followed instructions and were in the IRC channel."
[20:57]
mercutiobrycec: i like bw caps, i just think they have to be "reasonable" sizes
like would you mind a 2tb/month data cap?
[21:00]
mnathani_there, finally submitted the devio.us application [21:02]
brycecProbably not usually, I usually only hit 1.5-1.8TB/mo [21:03]
mnathani_I got an advertisement / flyer in the mail for 100 GB / 30mbit connection [21:03]
mercutiosee that's not reasonable [21:04]
mnathani_my current ISP is 400 GB, and uploads dont count neither do downloads 2AM - 8 AM (possibly 6 AM) [21:04]
mercutioi got a letter to "householder" for 40gb or something
oh home phone + broadband 40gb
[21:04]
brycecOh that's good that uploads don't count. 50% of my traffic are backups [21:05]
mercutioadsl
byo modem
i have vdsl and use way more than 40gb and use voip
[21:05]
brycecI'm still curious/tempted to drop my cable connection and just tether off my phone's unlimited data
see how "unlimited" it really is :D (LTE speeds too)
[21:05]
mnathani_940 Mbps / Unlimited from another provider for $150/month
w00t, devio.us account got approved
[21:06]
mercutiohaha
bryce was watching? :)
[21:08]
brycecyep ^ [21:09]
mercutiohey my devio.us account isn't working [21:09]
brycecmercutio: in what way? [21:10]
mercutiomy key isn't logging in [21:10]
brycecmercutio: do you have an old dsa key? [21:10]
mercutiomaybe
did you upgrade sshd?
[21:10]
brycecAs part of OpenBSD, yeah [21:10]
mercutiooh
damnit
mercutio tries to guess what his password may be
[21:11]
brycec"In ssh, turn off DSA by default. Add HostKeyAlgorithms to the server and PubkeyAcceptedKeyTypes to the client side so it can be turned back on."
And I have no intention of re-enabling it.
[21:12]
mercutiooh think i found it
it's in email
[21:12]
brycec..you never changed it from the default? Oh, Ben...
s/default/temporary
[21:12]
BryceBot<brycec> ..you never changed it from the temporary? Oh, Ben... [21:12]
mercutionope must have changed it
i did change it :)
i just can't recall it :)
[21:12]
brycecGlad to hear. [21:13]
mnathani_glad to hear that he cant recall ? lol [21:14]
brycecbrycec was curious to know who was "userauth_pubkey: key type ssh-dss not in PubkeyAcceptedKeyTypes" and I guess I know now.
mnathani_: That he changed from the temporary password :P
mercutio: devio.us/forgotpassword
if you need it
[21:14]
mercutioyeh there [21:14]
brycecI promise not to shame you too hard [21:14]
mercutiowell it supports ecdsa keys now
heh
[21:15]
brycecWe've supported ecdsa and ed25519 for awhile now, probably a year or so [21:16]
mercutioyeah i hardly ever login [21:16]
brycec(ecdsa since December 2013, ed25519 since April 2015)
(At least based on the dates in https://devio.us/fingerprints)
[21:17]
mercutiomy zsh history doens't have timestamping
so still not sure
[21:18]
mnathani_is having a subdomain for web something I need to request? [21:19]
brycecYes
(It used to be automated, then things changed)
So if you want it, I have to do it manually.
mnathani_: is this a request?
or was it just curiosity?
[21:20]
mnathani_curiousityh [21:21]
mercutiodoes anyone use talk on there? [21:21]
mnathani_I got your message
dont know how to respond yet :-)
[21:21]
brycecSome do. I have "mesg n" [21:21]
mercutiojust "write mercutio"
^D to end i think
[21:22]
brycec(on an empty newline) [21:22]
mnathani_I am stuck in mutt composing and email in body and dont know how to get out
s/and email/an email
[21:25]
BryceBot<mnathani_> I am stuck in mutt composing an email in body and dont know how to get out [21:25]

[22:55]
mercutioyeah i thought someone would google it
i gave up trying to find a funny phrase :)
md5 is pretty weak these days
you shouldn't really use it.
well it's ok for verifying files etc.
but not for passwords
[22:56]
mnathani_how come the timezone on devio.us is EDT? [22:57]
mercutioit's east coast
should it be UTC?
mnathani_: you can set TZ environment variable to get local time
[22:57]
...... (idle for 25mn)
brycecmnathani_: because the server is physically located in EDT, and was started by two guys who lived in EDT. [23:24]
mnathani_k
how often is the member list updated? http://devio.us/members
[23:29]
mercutioheh that's quite a long list
of course i search for myself
[23:32]
mnathani_You don't have permission to access /~mercutio/ on this server. [23:33]
mercutioi haven't done anything with web [23:33]
mnathani_guess you dont publish anything [23:33]
mercutioi got server at arp like within a year
and didn't use that either
i had a server in NZ prior anyway.
dedicated.
i had a dedicated server like 14 years ago
with openbsd
it was 10 megabit ethernet at first though.
[23:33]
mnathani_am I supposed to get 100meg quota on devio.us?
current quota: 102400
[23:37]
mercutiowhere does it say quota? [23:37]
mnathani_mnathani@wolfman $ quota
Disk quotas for user mnathani (uid 6899):
[23:38]
mercutioi have 102400 in /var and 102400 in /home [23:38]
brycecbrycec has much more quota :p [23:39]
mnathani_is that 10 megs, or 100 megs? [23:39]
mercutiodive by 1024
divide
[23:39]
brycecThat list is updated once per decade apparently
(last modified December 25, 2010)
(I had no idea it was there, much less broken)
And yes, 100*1024=102400
And yes, 100*1024K=102400K
[23:40]
mnathani_how do I get vi to show "INSERT" mode when inserting? [23:44]
mike-burns:set verbose showmode
Or just: :set showmode
[23:49]
mnathani_mike-burns: thanks [23:51]
