| mkb | so I sit down at my CentOS desktop and find that it's calmoring to tell me about some notifications it's made up in my absence
the Automatic Bug Reporting Tool and an Update I've already learned that it expects me to click and swipe up like an iPhone, so I do that and they appear in the middle of the screen in a transparent window I didn't know what to do, so I clicked one that made it disappear all I know is that the automatic bug reporter was concerned about Firefox, but Firefox hadn't crashed Firefox does have a lot of bugs though | [06:18] | |
| ..... (idle for 23mn) | |||
| aha! it sent a mail to root
but it says firefox crashed and it was still there... | [06:43] | ||

| mike-burns | Quantum crashing. It's both crashed and not crashed at the same time. | [07:19] | |

| mercutio | hmm people were talking about arp on nanog | [16:36] | |
| staticsafe | indeed | [16:37] | |
| mercutio | bgp+routed ip
i think interest of small providers doing anycast is growing. and atm it seems easiest to use different providers which is kind of a pita | [16:45] | |
| staticsafe | i have PI space but no AS yet so no BGP for me yet | [16:50] | |
| mercutio | just a /24? | [16:59] | |
| staticsafe | yes and a v6 /48 | [17:03] | |
| mercutio | oh yip | [17:07] | |
| mnathani_ | so.. I managed to get openvpn to provide ipv6 connectivity via a v4 tunnel | [17:14] | |
| mercutio | nice | [17:14] | |
| mnathani_ | now I am having issues getting Router Advertisements to work on a Linux box to provide addressing to LAN hosts | [17:14] | |
| acf_ | using radvd? | [17:15] | |
| mnathani_ | static IPv6 addressing works for hosts behind the tunnel too so thats cool
acf_: I guess thats what I was looking for, wasn't sure what it was called | [17:15] | |
| acf_ | this is my config: http://paste.unixcube.org/k/96bcb8
/etc/radvd.conf | [17:15] | |
| mnathani_ | thanks | [17:16] | |
| acf_ | mnathani_: I'm guessing your client boxen are still mtu 1500..
are you having any trouble accessing Google services? | [17:19] | |
| mercutio | you should definitely clamp | [17:19] | |
| mnathani_ | not really using this setup for any real users
mainly testing vms and cisco devices I really should document the v6 over a v4 tunnel can radvd provide ipv6 default gateway | [17:20] | |
| acf_ | yes
that configuration does ^ | [17:23] | |
| mnathani_ | you are right. It was a dns / ipv4 issue | [17:27] | |
| acf_ | I think radvd can do IPv6 DNS | [17:29] | |
| mnathani_ | 1452 is the highest packet size I can ping google with | [17:30] | |
| ..... (idle for 22mn) | |||
| is it necessary to set the mtu on each host, or only the host terminating the vpn? | [17:52] | ||
| ........... (idle for 52mn) | |||
| acf_ | mnathani_: if path mtu discovery works, just on your VPN endpoint interfaces
but Google doesn't appear to handle PMTUD correctly, at least for IPv6 so you'd need to set the MTU on all of the hosts | [18:44] | |
| mnathani_ | in some tests I got upto 1402
other tests 1452 probably safe to set mtu to something like 1410 | [18:45] | |
| acf_ | yea
I use 1400 on mine, just to play it safe | [18:46] | |
| mnathani_ | does that set ipv4 and ipv6 at the same time?
or can you set them independently? | [18:46] | |
| acf_ | on Linux, that's the interface MTU
for all protocols I remember setting the MTU on Windows, and I think you might be able to do it per protocol | [18:47] | |
| mnathani_ | I guess I could try and set separate interface for v4 and v6
s/set/use | [18:47] | |
| BryceBot | <mnathani_> I guess I could try and use separate interface for v4 and v6 | [18:47] | |
| brycec | (In theory, 1280 is the "safest bet" for ipv6 mtu, it's the minimum) | [18:53] | |
| mnathani_ | does mtu have an impact on maximum speed attainable on say a speed test? | [19:05] | |
| brycec | Yes insomuch as it requires a higher packet rate to achieve the same bandwidth. | [19:11] | |

| mnathani_ has joined #arpnetworks | [19:40] | ||
| mnathani_ | brycec: gotcha | [19:41] | |
| brycec | It's not likely to have any /real/ impact on your speed though. | [19:42] | |
| mercutio | it might for bittorrent
but not for normal traffic well not much | [19:42] | |
| brycec | And not on <100mbps pipes | [19:43] | |
| mercutio | well ipv6 does increase overhead | [19:43] | |
| brycec | But if you're trying to sustain 1gbps for instance, then you start to care about your PPS a lot more. | [19:43] | |
| mercutio | 40 bytes for ip header, 20 bytes for tcp/ip, 12 bytes with tcp options
so that's 72 bytes.. oh right i would say not really depending on your system coalescing mostly fixes it. | [19:43] | |

| mnathani_ | @google coalescing | [20:10] | |
| BryceBot | 197,000 total results returned for 'coalescing', here's 3

| RandalSchwartz | nice... gcc built in 31 minutes on SSD. :) | [20:30] | |
| mercutio | that seems like a long time
is that with the double build thing | [20:30] | |
| RandalSchwartz | only one process
and whatever freebsd does out of the box it seems faster than before. we're live on the SSD now | [20:31] | |
| mercutio | gcc used to compile itself with itself after compiling itself with the system compiler | [20:31] | |
| RandalSchwartz | yeah, I think it did that | [20:31] | |
| mercutio | i haven't compiled it in years | [20:32] | |
| RandalSchwartz | now I'm building ffmpeg, and I can't figure out what needs it.
I should just uninstall it and see if anything complains. :) | [20:32] | |
| mercutio | i tried using gentoo years back
gnome took hours to buiild | [20:32] | |
| RandalSchwartz | "gentoo - for those times when your life isn't slow enough..." | [20:33] | |
| mercutio | it seemed like a good idea at the time | [20:33] | |
| RandalSchwartz | there was a lightning talk at SCaLE about picking a linux distro
it was pretty awesome | [20:33] | |
| mercutio | i am finding arch ok | [20:33] | |
| RandalSchwartz | yeah - the talks aren't archived online yet
I'm building packages at 730/hour :) | [20:35] | |
