WhoWhatWhen
pyvpxpyvpx would donate a vm happily, if he could get NetBSD on this damn thing once and for all
:p
[03:30]
.... (idle for 19mn)
mercutiowhy's netbsd not working? [03:49]
pyvpxit does not like the IPMI Virtual CDROM Drive [03:53]
mercutiocan it boot off floppy?
as archaic as that sounds :)
[03:53]
pyvpxdidn't bother to try as I assumed it was the same driver/code path.
also, that means I'd have to make one :p
[03:53]
mercutioi doubt it is.
virtual floppy i meant
[03:54]
pyvpxor install ancient netbsd and slowly upgrade? haha [03:54]
mercutioi've used virtual floppy on hp systems before. [03:54]
pyvpxI thought I'd be smart and install OpenBSD on one drive, then manually shoehorn netbsd on the other...but only one drive is bootable/recognizable in the system bios [03:54]
mercutiodamn [03:55]
pyvpxthen I tried a FreeBSD liveCD, but could not get networking to work at all?? didnt look into it futher.
brought up interface, added default route...no nothin'...even to the gateway address. ARP entry...but no icmp replies. I'm guessing that's a sysctl thing but...gah
I'm trying to move and I've already wasted a month (I'm happy to give up_the_irons "free" money though :P)
[03:55]
mercutiomaybe a problem reading the mac address?
and trying to use 00:00:00:00 or something
but i'm stabbing in the dark
[03:56]
pyvpxnah, it got the right one. just no packets passing. tcpdump just shows STP frames and nothing else. [03:56]
mercutiodid you try in promisc mode? [03:57]
pyvpxso I'm further guessing it somes weird liveCD thing I dont know or care to investigate futher. by now, if I had any kernel hacking skillz, I'd have patched netbsd and had it installed :p [03:57]
mercutioheh
what's netbsd actually doing?
does it show the cd?
[03:57]
pyvpxI could install a bootloader on the first drive that points to an install on the second drive and try my luck that way [03:58]
mercutioor you can't even load the kernel? [03:58]
pyvpxkernel loads, but then it can't mount the root filesystem as, according to the kernel, sd0 is offline and unable to be opened
"sd at scsibus0 target 0 lun 0: <IPMI, Virtual Disk, 3000> disk removable
[03:59]
mercutiohmm [03:59]
pyvpxcd0 at atapibus0 drive 0: <IPMI, Virtual CDROM, YSOJ> cdrom removable
sd: drive offline
sd: unable to open device, error = 19
etc etc
boot device: cd0
then it errors out and asks where to find the root filesyste :p
I had this problem with another cheap provider
when I needed a box in london for some things
wasted 99EUR and a month
was convinced it was their shotty iDRAC
nope, turns out NetBSD just has a bug that no one hits or cares to fix?
ich wiess es nicht
[03:59]
mercutiothat sounds like a damn annoying bug [04:01]
pyvpxgranted had I posted to the mailing list months ago, perhaps I'd have gotten some response or traction. rather than where I am now, politely bothering people in #netbsd and scratching my head
trying weird OS gymnastics
pyvpx really just wants a shiny new netbsd/xen install, or three
[04:01]
mercutionetbsd dom0? [04:02]
pyvpxja [04:03]
mercutioi have a kind of crazy idea to get an install going
setup an install, save it as a file, use a linux live cd and dd it onto the drive.
err save the raw dd data
but it'd be nicer if could get it to work normally, as what happens if it goes wrong etc.
although it's probably easier to try to get it going if you can boot normally :)
hmm
you could also try pxe if you ahve another computer on the network
[04:04]
............... (idle for 1h13mn)
pyvpxnope, no other ones. and yeah, that was my idea with the freebsd liveCD. only I just wanted to network access instead of asking for yet another iso (or .img) added to the ISO library.
I think I'll just ask as best I can on the netbsd mailing list if someone will hold my hand through debugging and patching this.
it *can't* be too difficult. it works flawlessly in open and free....
famous last words, of course.

mercutiooh this is vps [12:15]
brycecWhy would a VPS have IPMI? [12:16]
mercutioipmi made me think dedicated. [12:16]
brycec^ [12:16]
mercutiocos otherwise there's not iso library is there? [12:16]
brycecactualyl mercutio it can be, of course
(VPS CD comes up as: [ 271.622784] scsi 0:0:1:0: CD-ROM QEMU QEMU DVD-ROM 1.0 PQ: 0 ANSI: 5)
*actually
[12:16]
mercutiotrue, i didn't know if netbsd was doing something weird
if it's dedicated it's probably yet another intel revision of ethernet breaking freebsd
which would make sense
[12:17]
brycecDon't dedicate boxes have a VPN-only address (and address space)? Or is that just the IPMI controller?
And as I recall, they are dual-NIC, so one would have to be sure they're configuring the correct interface.
[12:23]
......... (idle for 43mn)
mercutioboth interfaces are on the same network
so either should work
[13:06]
brycecTrue. i wonder, if a switch is configured for [static] port bonding, would the other end also need to be configured as such? Or would simply operating a single interface work? Probably depends on the type of bonding... [13:11]
mercutioyou should be able to alternate what ports you stick packets out on
but they may get reordered, as it's separate switches
and it's gigabit anyway so not really necessary.
there's something on the wiki somewhere about ways to set it up so it can failover
actually that reminds me, i dunno which switch the ip/kvm is on
i've been thinking about playing with bonding at home
but you kind of need more than gigabit from two cards.
[13:12]
BryceBotThat's what she said!! [13:14]
mercutioso i thought it'd be kind of cool if it could route one of them over infiniband
i cap under port speed anyway
if you've got gigabit ports, then if something local sends at full gigabit another host can get impacted slightly
so i just cap most ports at 900 megabit
then stick fq_codel on it

m0undsstaticsafe: are you using dhcpv6 on your mikrotik box? [17:22]
staticsafem0unds: nope [17:22]
m0undscomcast enabled ipv6 for biz subs in my market, but dhcpv6 is lame and the implementation on my srx is buggy [17:24]
figured i might try my rb450, but there's a chance it's buggy on that thing too, haha [17:34]
mercutiois it dynamic ipv6? [17:46]
m0undsthey dynamically assign a prefix
you use IA_PD "hints" to request larger allocs
comcast will provide /64 by default, will allow resi customers to request a /60 and will allow biz to request /56
unfortunately, for whatever stupid reason, juniper's IA_PD support is hardcoded to request a /48 and there's a dev request being completed to allow that to be specified in the cli
so it requests a /48 and gets a /56 and ignores it
[17:52]
....... (idle for 33mn)
staticsafem0unds: i don't use it but there are probably people in #ipv6 who use DHCPv6-PD on RouterOS, IIRC it works fine
i had someone IRC ask me for help for it earlier and they had comcast
it worked fine iirc

staticsafe: have you seen the fun stuff you can do w/the ammo pack + aircraft in ps2?
[20:38]
staticsafeyeah [20:39]
m0undsi had no idea
someone put a pack on the nose of my mosquito and i did a rapid vertical take off and did 3 flips and blew up. it was amazing.
[20:39]
staticsafeoh i recorded something today that was amusing
lemme see if i can cut it up
need some decent video editing software hm

m0undshaha, enabling dhcpv6 on my rb crashes it
updated to 6.23, and it crashes when i load/unload qos queues and also when i enable dhcpv6
[22:44]
brycecYou know what doesn't crash? pfSense :P [22:45]
m0undslots of other things don't crash either
i figured i'd see if routeros 6 still sucks on the 450g, and it does
[22:48]
brycecBummer [22:52]
m0undsstill crash-happy, over a year since i last tried it [22:52]
brycec(I know, I'm not helpful :p) [22:52]
m0undssrx> show system uptime
Current time: 2014-12-05 23:51:05 MST
System booted: 2013-12-26 15:27:44 MST (49w1d 08:23 ago)
^ there's something that doesn't ever crash
haha
only reason it was rebooted was for a firmware update (flow support for ipv6)
