03:33 < BB> is there a way to increase the stack so i dont get "Kernel panic: Kernel stack overflow" or is that related to something else?
03:33 < caker> BB: how much memory are you giving your UML?
03:33 < BB> 512MB
03:34 < caker> You need to set .. hmm can't remember kernel config option -- kernel address size from 1 to 2 (it's in .5GB chunks)
03:34 < caker> Give that a try... ?
03:34 < BB> i also tried with 256M and the same happened
03:35 < caker> that is weird .. when does it do that? in skas mode?
03:35 < BB> do you think it could just be out of memory?
03:35 < BB> caker its in skas atm but i've also tried with tt and it also dies
03:36 < caker> bb: kernel panic? doubtful that's correct
03:38 < BB> i also dont have any swap, maybe that isnt helping
03:44 < BB> it only dies after like 8hrs so will come back in a few days with it after i've tried a few things heh
03:51 < BB> hmm i already have half gigs set at 4

03:56 < newbie> hi all
03:57 < newbie> who can give me some advice about route?
03:57 < BB> hi
03:57 < newbie> hi BB
03:57 < newbie> nice 2 meet you
03:59 < newbie> ?
03:59 < BB> i guess it depends on what advice your looking for about router
03:59 < BB> -r
04:00 < newbie> my uml cannot ping other host
04:01 < BB> how have you got the networking setup?
04:01 < newbie> ./linux ubd0=.... eth0=ethertap,tap0,,10.1.1.253
04:02 < newbie> then i use ifconfig to up uml eth0 interface
04:02 < newbie> uml can ping it's host,but cannot ping other host
04:03 < BB> do you have a default route on the uml ?
04:03 < newbie> yeah
04:03 < newbie> i add default route 10.1.1.253
04:03 < BB> the same as what the uml uses?
04:04 < newbie> my host ip is 172.16.51.82, and its tap0 ip is 10.1.1.253
04:04 < newbie> uml's ip is 10.1.1.254
04:04 < newbie> i followed the instruction of PCP article
04:05 < BB> and the host is setup to masq the data from the uml?
04:05 < newbie> uml can ping 172.16.51.82
04:05 < newbie> yeah
04:05 < BB> it would have a route to 172. ip though through the host
04:05 < BB> if you had ip forwarding enabled on the host
04:05 < newbie> but cannot ping other host
04:06 < BB> and you've setup iptables/chains?
04:06 < newbie> ip_forward is on
04:06 < newbie> no iptable
04:06 < newbie> and chains
04:06 < BB> it will need something to masq the data otherwise your 10.x.x.x ip wont get anything back
04:07 < newbie> how to do?
04:08 < BB> http://www.tldp.org/HOWTO/IP-Masquerade-HOWTO/
04:08 < BB> i have to go otherwise i'l be late for work again
04:08 < newbie> thank you very much
04:09 < newbie> bye

09:21 < oznoodle> I'm a bit confused by the intention of host patches: is skas3 
09:21 < oznoodle> meant to compile on 2.4.21 without further ptrace modifications?
09:29 < oznoodle> If I use http://kernels.usermodelinux.org/host/host-skas3.ptrace.patch.bz2 
09:29 < oznoodle> I get a tree that won't compile, but the contents of the patch look as 
09:30 < oznoodle> though the formerly separate ptrace fixups found their way into the
09:30 < oznoodle> kernel.
09:30 < oznoodle> So, short version of the question: what's the recommended way to produce
09:30 < oznoodle> a skas3 version of 2.4.21? Thanks.
09:31 < desaster> i just patched 2.4.21 with host-skas3 patch from user-mode-linux.org
09:34 < oznoodle> You mean http://prdownloads.sourceforge.net/user-mode-linux/host-skas3.patch?
09:35 < desaster> yep
09:36 < desaster> i should've said user-mode-linux.sf.net
09:40 < oznoodle> From memory the problem was in ptrace.c with modify_ldt of all places,
09:40 < oznoodle> unfortunately I don't have any Intel machines at home with me tonight
09:40 < oznoodle> but I'll start again tomorrow. You've got to love uml, look somewhere
09:41 < oznoodle> else for a month and it's all different :-) Incidentally (my first time 
09:42 < oznoodle> here) is this the place to discuss modifications made to David Coulson's
09:42 < oznoodle> uml daemon?
09:44 < desaster> perhaps when david is around ;)

10:51 < rob> Hi
10:51 < yeti> hi
10:51 -!- rob is now known as shak
10:51 < yeti> i knew i saw "rob" before ;-)
10:51 -!- shak is now known as rob
10:51 < rob> :p
10:52 < yeti> how's your uml research?
10:52 < rob> its going ok
10:52 < rob> I had to put a hard disk in a server in London :/
10:52 < rob> so I haven't got a spare yet :(
10:53 < yeti> no problem
10:53 < yeti> you have a nfs-server?
10:53 < yeti> how about diskless umling?  ;-)
10:53 < rob> I dont have space for a NFS server :(
10:53 < yeti> ohhh...
10:54 < yeti> i have a k6-2, 500 MHz, 512 MB ram, minimal woody installed, rest as volume group for umls here
10:54 < rob> :)
10:55 < yeti> if all else fails i can give you an uml on that system ;-)
10:55 < yeti> but i only have a 23:59-line
10:55 < yeti> one linedown per day and changing adress
10:56 < yeti> maybe we should start something like a wiki for the brainstorming
10:56 < yeti> too much possibilities...
10:56 < yeti> i had some success with statically linked kernels
10:56 < yeti> i wanna be able to allow the uml owner to compile their own kernels
10:57 < yeti> that could turn into a security problem...
10:57 < rob> I saw in david's kernel store that therer was a web interface for compiling it...I think.
10:57 < yeti> but as long as all umls are run by myself i wanna be able to compile the uml's kernel inside the uml itself
10:58 < yeti> that would make the uml owners more feel like on a normal system
10:58 < yeti> and not to get dependencies to shared libs of some distro, skas+static-linkage is the only way i see for that
10:59 < david> yeti: then the distro is broken
10:59 < david> yeti: UML handles dynamic linked stuff perfectly fine
11:00 < yeti> what if i compile an uml kernel on a gcc3 system e.g. gentoo and want to run it on a gcc2 system, e.g. woody?
11:00 < david> rob: the web i/f isnt complete so won't compile anything
11:00 < david> yeti: who cares?
11:00 < yeti> me
11:00 < david> yeti: the kernel is statically compiled
11:00 < david> it makes no difference what the kernel is compiled with in relation to everything else
11:00 < rob> david: it looks damn cool
11:00 < david> rob: thanks :-)
11:01 < rob> its a super idea :)
11:02 < Lathiat> david: did you nuke my vm?

12:44 < muss> Has anyone tried getting bluetooth to work with the UML kernel?
12:44 < david> muss: how would that work?
12:44 < david> muss: how would UML access the bluetooth hardware?
12:44 < muss> well, they are usb dongles
12:45 < david> right, and UML would access that how?
12:45 < muss> and you can access the hosts usb hardware from within uml, no?
12:45 < david> there is a patch to do it, but I've never tried
12:45 < muss> well, you can also have virtual bluetooth devices and run them over tcp/ip.
12:46 < muss> I would just have to install the modules.
12:46 < david> muss: assuming the UML has support to do that, then you can do it
12:47 < muss> Well, the bluetooth options dont show up when configuring the kernel...
12:47 < muss> as a UML kernel, anyway
12:48 < david> maybe you need to modify the config.in in arch/um to include the bluetooth stuff
12:48 < muss> hmm
12:48 < muss> is it possible to patch the uml kernel, and have that stuff show up when configing the uml kernle?
12:54 < david> you may need to manually modify some configuration scripts to do that
12:54 < david> if it's not arch specific, it should work
