Guest6894hey
does anyone have an example of what the /etc/networks/interfaces is supposed to look like
for ipv6
[09:46]
m0undsGuest6894: for any particular os? [09:47]
Guest6894the debian like os
that uses /etc/netowrks/interfaces lol
what else uses that
[09:47]
m0undsm0unds isn't a mindreader
m0unds also doesn't use debian
[09:48]
Guest6894ah
neither do I thats why Im asking
[09:48]
m0undshttps://duckduckgo.com/?q=static+ipv6+address+ubuntu [09:49]
antGuest6894: http://pastie.org/9355262 - replace fe80:: by your actual network [09:49]
Guest6894yes I know I can search for examples however
its not setting up the interface correctly
[09:49]
m0undsifdown ifname && ifup ifname
if the script isn't doing it right, that might help
[09:50]
Guest6894weird
thats exactly what I have ant
[09:50]
m0undse.g. ifdown eth0 && ifup eth0 [09:50]
staticsafeGuest6894: one sec
lemme paste you one of my configs
[09:50]
antGuest6894: what does "ip addr sh eth0" show? [09:51]
staticsafehttp://pastie.org/pastes/9355268/text?key=tkuojock4i0iujmettzg [09:51]
Guest6894ant: its not what that shows its what route -A inet6 shows isn't correct
oh
the gateway I see
awesome
thanks staticsafe
[09:51]
staticsafenp [09:53]
Guest6894also thanks ant [09:53]
antnp [09:53]
Guest6894it was just the gateweay I was setting it to my 2607:f2f8:a2c4::1 instead of fe80::1
although
I think I still need to add 2000::/3
[09:54]
antisn't that what it's supposed to be? [09:55]
Guest6894I guess I should probably understand what those addresses are
I'm not sure
I really dont understand ipv6 yet
thats why I've been setting this up lol
basically I have my /48 setup, and my vpn clients connect and get ipv6 and that all works and its tested
[09:55]
antgotta go [09:56]
m0undshttps://ipv6.he.net/certification/ is sort of helpful to get some fundamentals down
but it's not comprehensive by any stretch
[09:56]
antoh, for the /48 it's a bit different anyway [09:57]
Guest6894now I'm bridging the tap0 on my vpn client for VM's and it works for windows and gentoo I just need to figure out this route stuff
m0unds: is it pretty quick
[09:57]
m0undsGuest6894: maybe 30 mins
if that
[09:57]
Guest6894I need need straight to the point kinda stuff [09:57]
m0undslots of silliness [09:57]
Guest6894I'll check it out [09:57]
m0undsnot super in depth, and you get a t-shirt out of it (assuming they're still sending those out) [09:58]
Guest6894lol
nice
[09:58]
***Guest6894 is now known as erratic [09:58]
m0undsit's the ugliest shirt i own
hahaha
[09:58]
erraticnice
do they sell girl sizes
no wait that would be no fun
I should ask for xxl
and get mustard stains all over it
lol
[09:58]
m0undsit is white, so it's perfect for mustard stains [09:59]
erraticnice
well I know now I can fix this problem with post-up /sbin/route -A inet6 add 2000::/3 gw 2607:f2f8:a2c4::1
but I wonder if theres a better way.
Ill check that site m0unds thank you
I'm finding more and more that I could care less if the rest of the internet isn't on ipv6 its just nice being at least partially there and not behind nat
pretty much everything I care about is ipv6 and alot of my friends have tunnels
[09:59]
m0undsi used my arp vm for a tunnel ep for a while, just had to stop because of the comcast -> ntt congestion and packet loss
(no fault of arp at all)
[10:05]
erraticcomcast is stupid [10:07]
m0undsmeh [10:07]
erraticthis is well known [10:07]
m0undsjust say $isps are stupid
because they're all congested to ntt
haha
[10:07]
erraticI haven't had any problems with tmobile
other than its a little slow
its usable though
who do you know that uses tmobile data though :)
[10:08]
m0undsi don't actually know anyone who has tmobile period - their network in abq metro is horrendous [10:09]
erratichaha
its ok here
seattle
Im about to move to another country though so things should get interesting
[10:09]
brycecFYI erratic when asking for ipv6 help in here, it's important to point out that you're using a /48 vs a /64 as they're configured differently. And while I'm at it, here's mine http://sprunge.us/hYCF
(indeed it is a very, very white shirt. not at all pretty. but very, very free.)
[10:15]
m0undsyup
my wife stole it
in fact, she's stolen most of the free shirts i've gotten over the years from vendors and stuff
[10:19]
bryceclol [10:19]
m0undsthe ones i get at casino gaming conferences are pretty hideous too
i had one that had a mashup of new slot graphics on it. looked like something you'd get at a state fair airbrushing booth
[10:20]
brycecI assume your wife isn't a 12 year old latina girl?
Those are the only persons I've seen wearing those types of airbrushed shirts
[10:23]
m0undsthese ugly shirts are for sleeping only
haha
closet full of jorge + melissa por vida t-shirts
the ones w/the drama masks on them
they pair well w/glamour shots
[10:23]
erraticbrycec: thank you :)
brycec: it will prob help once I understand ipv6 a bit better for sure though

acanthusHey i was just wondering if anyone has gigabit on their vm
Like can you set the mtu higher
Ivw never understood how that works
Everything in between matters too doesnt it ?
[13:37]
gluffis_yes... [13:38]
acanthusHow high can you set the mtu [13:39]
gluffis_so trying to use jumboframes over the internet is quite useless [13:39]
acanthusIts like 6000 right ? [13:39]
gluffis_depends on your NIC, but 9000 is usually the largest
low en realtek is at 4000
low end
[13:39]
acanthusWhat about like virtio
acanthus checks
http://serverfault.com/questions/460881/jumbo-frames-between-kvm-guest-and-host
[13:40]
gluffis_nfs likes jumboframes :) [13:41]
acanthusSo does openvpn apparently
Though the tests i saw were kinda weird
But ssl is more efficient with less frag
That was openssl not sure about polarssl
Which ive switched over to using
Polar is cold man
[13:41]
m0undsare you doing jumbo frames between two VMs on the same lan segment or something? [13:47]
acanthusHahaha i showed my bf my boot up screen for my box with 16 cores he said it looked like Antarctica because of all the penguins
Derp
Lol
Nah nothing yet
Id like to see what it can do
[13:48]
m0undsif it's remote boxes, you'd likely run into path mtu in the neighborhood of like 1480
maybe lower
[13:48]
acanthusIm really a self taught network engineer, my skills suck im trying to improve some by building networks [13:49]
gluffis_i need to replace that realtek crap with an intel so I can run 9k mtu at home :) [13:49]
acanthusYeah thats what i was afraid of
It sounds like everything into ntt sucks based on what people were saying here
[13:49]
m0undsyep, seems most isps are running that peering really hot [13:50]
acanthusI dont have anything at home thats not e1000 thankfully [13:50]
gluffis_:D
new machine...
[13:50]
acanthusI took some pics of my dual 8 core opteron yest [13:51]
gluffis_haven't gotten around to ordering a new card yet..
mostly bought car parts the last couple of months :D
[13:51]
acanthusId like some of those opteron 6378s or whatever they were, theyre piledriver/2.8 16 cores each and the proc is like 700
Want two
Lol
Cant really justify it
[13:52]
gluffis_i bought an i3 haswell... [13:52]
acanthusI have a couple of 6128s anf theyre a bit slow but still 16 cores
Well 2 8 core procs and i have 64 gigs of ram and i need to get another 64 because i cant put 2 on each proc for some reason
The ranking is weird
[13:53]
staticsafei7 haswell master race [13:54]
gluffis_ok [13:54]
acanthusIt was hella cheap too [13:54]
gluffis_i3, 16g ram and an ssd 250gb disk, works for me.. 500$ here [13:55]
acanthusWell overall i spent more like 5k on this box.
But im totally happy with it
[13:56]
gluffis_hehe
nowdays I hate computers
[13:56]
acanthusSec [13:56]
gluffis_i dont want to spend any money on them :) [13:57]
acanthusIll post pics in a bit i gotta get off at my bus stop
Bbl

[14:10]
m0undsfancy [14:11]
gluffis_hehe not yet :D
more fun
this is fancy, https://dl.dropboxusercontent.com/u/17613704/P1800/IMG_1725.JPG
[14:12]
m0undsyep, that's fancy [14:13]
gluffis_13000 metric miles :) would be something like 80k imperial [14:14]
staticsafeis that a mercedes? [14:15]
gluffis_haha nope, a Volvo [14:15]
staticsafeah [14:16]
gluffis_from 1968 [14:16]
acanthusI feel bad
I just came to visit my mom and blew her off
[14:16]
gluffis_hehe [14:17]
acanthusI had something i wanted to look up and completely forgot
Staticsafe i had a friend that had a 450sl that was rebuilt and had a factory restored chasis because there was a recall on them
Pretty expensive
[14:17]

acf_nice. Thinkpad X61s here
anyone notice a significant increase in SIP registration brute forcing recently?
it seems to be eating up between 0.8 and 1.0 Mbps of bandwidth now
[21:59]
mercutioacf wow
maybe you should use a different port
i've seen moer than usual too
but i don't think it's anything liek that much
[22:06]
acf_yeah it's pretty bad [22:06]
mercutioyeah some of them, even if you block their ip will keep trying again
once you're on some stupid list
[22:06]
acf_http://unixcube.org/who/acf/tmp/siptraffic.png
^ pretty much all of that is sip traffic
[22:08]
mercutiowow
i used to grpah my dsl
it was so boring looking :)
i suppose i can again
[22:08]
acf_it's nice for catching things like this [22:09]
mercutiobut there was shit all sustatined, it was just up and down and up and down
yeah
i'd have to isntall cacti at home though
[22:09]
acf_yeah, maybe not worth it [22:10]
mercutioi wasu sing mrtg before
which is slightlky simpler
but 95th percentile is cool
well it just means i should stick more ram in my home server first
[22:10]
acf_the total bandwidth thing seems to be a bit broken [22:10]
mercutioi've got ram waiting to put in to jump from 8gb to 24gb
but i don't really like rebooting :)
[22:10]
acf_I know what you mean
22:10:54 up 401 days, 19:54, 1 user, load average: 0.08, 0.04, 0.05
up_the irons has better :)
[22:11]
mercutioheh
my sip pabx is locked down for what ip's can reach it
but that means i can't go in via cellphone network :(
