I need my account be upgraded staticsafe: vin: send an e-mail to support@ dominicl: are there any staff here at all?
it seems arpnetworks is a one man team too..is that true? staticsafe: it is
the topic says so even dominicl: ah ok, so support is slow sometimes? staticsafe: indeed, also up_the_irons is in PST timezone so mind that dominicl: hm, wondering whether to sign up or not staticsafe: i haven't had to contact support yet for any reason ;) dominicl: ah right jpalmer: I contacted support once, to add more VPS's :) dominicl: nice jpalmer: dominicl: IMO: if you are good with admin, the support thing isn't much of an issue. if you occasionally goof up and need "hands on" then.. ARP may not be the best choice for ya.
just my opinion of course. -: staticsafe agrees vin: hmm thats why its called unmanaged service GluffiS: pretty stable, 6:42AM up 647 days ***: dzup has joined #arpnetworks

welcome back! up_the_irons: mike-burns is still in the vortex... brycec: tsk tsk up_the_irons: he was the last remaining nick in the split channel brycec: oh there was an entirely separate channel created in the split?
Pretty intense... usually the netsplit server will either rejoin or kick everyone
Must've been pretty bad to have a split-brain come up staticsafe: certain servers were isolated from the network
Freenode was getting DDoSed yesterday brycec: yep, but they usually figure out they're disconnected and boot everyone to force 'em back to a live server up_the_irons: yeah the channel never rejoined brycec: Well you're back, and responding to tickets *nudge nudge* so that's all that matters
:D -: brycec just wants to try out the gbe link up_the_irons: brycec: i actually *am* replying to yours at the moment... brycec: yay! up_the_irons: brycec: can u give your vps a hard reboot now? brycec: yep, gimme two shakes to pull up vnc...
(vnc to enter the encryption key) up_the_irons: k brycec: going down...
powered off...
booting...
bios... up_the_irons: neat -: brycec wonders what's taking the bios so long... brycec: grub...
decrypted...
booting...
oooh eth1 up_the_irons: haha brycec: it's very quiet on eth1... mercutio: up_the_irons: how's the ntt circuit coming along? -: mercutio has had bad routing for a while now :( up_the_irons: mercutio: in provisioning stage
brycec: should be extremely quiet
i think only 1 other person has a direct link
brycec: i just sent the ticket reply -: brycec just received the reply
up_the_irons m/ brycec: Thanks up_the_irons !
fwiw NFS has generally been rock solid for me. I swear by it. up_the_irons: brycec: np, does it work? :)
brycec: which version of NFS? mercutio: brycec: with linux? up_the_irons: and on which platform?
linux/freebsd/... mercutio: most people swear at it. up_the_irons: hahhhahahahah brycec: up_the_irons: nfsv3 (v4 was a nightmare..) on linux, freebsd, and osx mercutio: stale nfs handles brycec: (though osx has some weirdness...) up_the_irons: ok, i'll note the v3 mercutio: About 479,000 results (0.24 seconds) up_the_irons: i think the last i tried was v4 brycec: v4 has bells and whistles... but is really complicated compared to v3 up_the_irons: i c mercutio: that said most of my linux nfs problems were years ago brycec: And v4 wasn't supported by the centos 5.x install environment, so I had to roll bacjk mercutio: and mostly to do with reboots.. -: brycec does craploads of netinstalls mercutio: i used to use nfs mounted / brycec: I still do
my testbench is 100% netboot (because fuck drives) mercutio: cool up_the_irons: lol mercutio: i used to do remote X too brycec: heh, X... what a b/w whore. mercutio: thin clients kind of fell out of brycec: I recently used NX (NoMachine) and that is very, very slick mercutio: i've lost the word brycec: fashion?
use? mercutio: yeh that'll do
i just used it on lan
I tried over DSL
it's pretty bad.
actually xterm is ok brycec: heh yeah... if it's a small window mercutio: gtk applications are terrible
gnome-terminal is probably terrible up_the_irons: brycec: let me know if you have ping6 that link local address i gave ya brycec: up_the_irons: From fe80::5054:ff:fe2b:8374 icmp_seq=1 Destination unreachable: Address unreachable mercutio: on that note, has anyone had much luck running X on windows? -: brycec had to look up and find that he needed -I eth1 for LL up_the_irons: brycec: yep, i missed up.. another hard reboot plz :) brycec: boooo okay up_the_irons: brycec: for the ping, you just qualify the v6 address with the interface, like:
ping6 fe80::5054:ff:fe89:c122%vlan71 brycec: going down.... up_the_irons: in that case, the int name is vlan71, but you would do like "%eth1" brycec: Yeah % should work too
going up...
I appreciate that the BIOS gives me a fighting chance to hit F12.... but sometimes it's annoying up_the_irons: i set it for 15 seconds... i didn't want to make it too long, cuz then all boot times are higher brycec: heh
up_the_irons: no-go still
So just to be clear - this vlan is shared among other hosts (potentially),r ight?
(ie. I should firewall it accordingly) up_the_irons: brycec: yes, firewall it if need be
brycec: what's your link-local side addr? brycec: 21:45:13 < brycec> up_the_irons: From fe80::5054:ff:fe2b:8374 icmp_seq=1 Destination unreachable: Address unreachable
fe80::5054:ff:fe2b:8374 -: brycec tcpdumps...
up_the_irons ponders... brycec: (and no, I don't have any firewalling active)
(yet) up_the_irons: OH
i know brycec: ifconfig vlan71 up
:p up_the_irons: brycec: try now :) brycec: hey, you're pinging up_the_irons: woo
64 bytes from fe80::5054:ff:fe2b:8374: icmp_seq=410 ttl=64 time=0.595 ms

I was about to complain that I was still seeing 100mbps speeds, but I decided to retry with a ramdisk as the destination instead
damnit... cache
sent 244559550 bytes received 31 bytes 12541516.97 bytes/sec
still 100mbps
(to a tee)
fuck
ignore me... -: brycec was still on the old public iface up_the_irons: lol
i have our ISO volumes replicated over that link, so i know it is f'in fast :) brycec: heh
sshfs is being a little bitch with the whole %eth1 bit up_the_irons: hah brycec: hush you, mr "let's be progressive here" :p
"If host is a numeric IPv6 address, it needs to be enclosed in square brackets."
-.-
rtfm ftw
okay okay okay, real performance now... up_the_irons: LOL brycec: copying from the backup server to a ramdisk, just over 100mbps
sent 244559550 bytes received 31 bytes 13219436.81 bytes/sec up_the_irons: yeah, you get used to the square brackets if you do enough ipv6. apache does the same thing. brycec: copying to the backup server, sub-100mbps. sent 244559555 bytes received 31 bytes 9228663.62 bytes/sec up_the_irons: brycec: just do a straight scp of some huge file, you should see like 500 mbps (i haven't found a single stream go faster than that, it might be an mtu thing or w/e...) brycec: this might be a dumb question, but can I set the mtu to 9000 on the iface? up_the_irons: i think u can brycec: i would be used to [], except all my ipv6 is config'd by slaac (or manually, which is sans-[]), using hostnames, or ssh (or ping6 or nmap) which don't mind it sans-[]
yep, mtu set to 9000 and ping still works... ***: whitefang has quit IRC (Quit: Leaving) brycec: avg speed still 100mbps. The first 111MB went at 40MB/s, then it stalled for 5 seconds, and it was never as quick
seems like I starved your cache or something
s/starved/exhausted/
(that was vps->backup)
s/vps/vps-ramdisk/
backup->vps-ramdisk was much, much quicker (probably still in the server's cache), 40MB/s up_the_irons: brycec: 40MB/s =~ 320 Mbps
brycec: i just up'd the mtu on both sides on my end, btw
brycec: so give it another try brycec: (oh yeah, both ends... heh)
hmm something broke
ssh is hanging mid-negotiation
(they connect, but die during handshaking and such) up_the_irons: hmm.. ping still works brycec: I've seen this before
when the MTU was too high up_the_irons: o'rly? brycec: packets started dropping over a certain size
probably the mtu
it's google'able
http://www.snailbook.com/faq/mtu-mismatch.auto.html
(tcpdump shows it constantly retrying)
(feel free to abuse ssh and try logging it) up_the_irons: hmm.. i wonder if the taps and br's also need to be changes
damn lots of changes brycec: heh, could be up_the_irons: brycec: give it another try, just to see if it doesn't stall (changed your tap mtu to 9000) brycec: hangin' up_the_irons: brycec: one more time brycec: just went through
yep, connects now nixbag: hurray! up_the_irons: oh hey nixbag , how's missouri? brycec: vps-ramdisk -> backup server 23.3MB/s (186mbps) nixbag: up_the_irons: i'm back in LA now. up_the_irons: i wonder if kvm networking is just hitting some cap
nixbag: that was 2 weeks??
man time flies brycec: oh hell...
up_the_irons: my ssh has frozen, and vnc "Faield to connect to server"
(this happened as I started a backup->vps scp) up_the_irons: brycec: hmm brycec: (and needless to say, no response to pings) up_the_irons: brycec: your vm appears stopped
i guess it crashed :o brycec: well I didn't stop it... up_the_irons: i just started it for ya
hmm.. musta died then brycec: thx (I hit Boot too) up_the_irons: haven't seen that very much, but then again we're experimenting with new stuff... brycec: Let's try this again! dr_jkl: ow. i think i have arthritis :/ -: brycec really ought to setup the console too nixbag: up_the_irons: we cut the trip short because of incoming snow storms. brycec: up_the_irons: I'm seeing 40MB/s both directions pretty consistently :D
that is nice and fast up_the_irons: brycec: oh sweet
brycec: i need to find a way to get those MTUs persistent on your tap / br cuz when you reboot the interface is created a-new dr_jkl: openbsd is fun. brycec: oh goody... "Just don't reboot" -: brycec had a lovely 130+ day uptime before this up_the_irons: brycec: i made an adjustment, can u plz retest?
brycec: pfff.. weak sauce
$ ssh kvr06 uptime
21:56:59 up 1154 days, 18:50, 1 user, load average: 1.16, 1.26, 1.83
$
i hope it doesn't now crash tonight... brycec: up_the_irons: well I'm sorry I only recently signed up :P nixbag: you jinxed it. up_the_irons: brycec: lol brycec: backup->vps(ramdisk) 46.6MB/s, vps(ramdisk)->backup 38.9MB/s up_the_irons: so still good? brycec: I'm happy up_the_irons: cool, appears only the tap needs the 9000 mtu
no need to mess with the bridge interfaces brycec: Do I see an option in the portal to configure the mtu in the future? :D (or just set everyone to 9000... or just do it by hand/on request) up_the_irons: i think it's simpler to just try 9000 everywhere
if it's stable, then it's all good brycec: might cause confusion with fresh installs that attempt 1500 by default
(don't get me wrong, i'd love 9000 everywhere) up_the_irons: well, if the tap is 9000 on the host, but only 1500 on the VM side, that shouldn't mess with anything
the mtu is 9216 on all my "backplace" traffic ports, but the front-end NICs are still 1500 (cuz i'm lazy and get enough speed anyway)
brycec: can u test one more time? (sorry, didn't think we'd get into all this mtu stuff now :) brycec: up_the_irons: still good
backup->vps(ramdisk) 46.6MB/s, vps(ramdisk)->backup 38.9MB/s (again) up_the_irons: brycec: ok nice
seems like the vlan on the backup server doesn't need the 9000 mtu either. like, only "physical" interfaces
gonna reboot the backup server to make sure the mtu sticks brycec: noooo -: brycec points to his active xfer
brycec watches things fail up_the_irons: woops brycec: sshfs does NOT like yuo right now, up_the_irons -: up_the_irons apologizes to sshfs brycec: in my testing and "real" use: (rx/tx) max 391.09 Mbit/s | 339.03 Mbit/s
looks like we're back up up_the_irons: mtu stuck, yay brycec: great up_the_irons: btw, i added the backup space to your Portal profile, officially
you'll see more options now brycec: options where? up_the_irons: in portal brycec: oh cool! up_the_irons: click "Backup Space" -: brycec did up_the_irons: i'll spoil the surprise: just let's you submit new ssh keys brycec: I love that df tells me I can write out another 2.7TB... in a 20GB quota :p
*2.5
**2.6
up_the_irons: that's not all - also mentions the hostname up_the_irons: brycec: is this over sshfs? brycec: even though the hostname doesn't match the ipv4 address you gave out
up_the_irons: Yes up_the_irons: cuz 'df' is not a binary within the chroot, so you can't see it while logged in brycec: lol sorry for the confusion
yes, df against the sshfs mountpoint up_the_irons: brycec: interesting. dunno if there's anything i can do about that brycec: probably not
unless you can fuck with sftp on the server up_the_irons: yeah true brycec: up_the_irons: Could I ask for a bump in my quota? -: brycec replied to the ticket instead/too ***: Ehtyar has quit IRC (Quit: +++ OK ATH OK) toddf_: interesting, the openbsd implementation of virtio networking can only do a mtu of 2024 not 9000 up_the_irons: toddf_: whoa weird
