02:13 < clever_jeff> hey, I can boot fine into my UML Environment, but it doesn't seem to launch "login"  (ie, no login prompt), is this a problem with the root-filesystem?  I'm using the 6.2 server image from the site....
02:13 < clever_jeff> anyone that can shed a tid-bit of light on my problem?
02:13 < caker> clever_jeff: what's your uml command line?
02:14 < clever_jeff> ./uml-linux 3 ubd0=root_fs.rh-6.2-server.pristine.20020312
02:14 < clever_jeff> i was playing with runlevels, without the 3, same thing, but 'single' does perform as expected
02:15 < caker> try adding: "con=null con0=fd:0,fd:1" and make sure a getty is listing on tty0 (/etc/inittab)
02:15 < clever_jeff> hmm, thanks, lemme try
02:21 < clever_jeff> grr, no such luck...
02:22 < caker> try this then
02:22 < clever_jeff> does it have something to do with:
02:22 < clever_jeff> INIT: Id "0" respawning too fast: disabled for 5 minutesINIT: Id "1" respawning too fast: disabled for 5 minutesINIT: Id "2" respawning too fast: disabled for 5 minutesINIT: Id "c" respawning too fast: disabled for 5 minutesINIT: no more processes left in this runlevel
02:22 < caker> con=null con1=fd:0,fd:1
02:23 < clever_jeff> con=null con1=fd:0,fd:1 just stops at:
02:23 < clever_jeff> Initializing software serial port version 1mconsole (version 2) initialized on /home/p06/.uml/AYmYw8/mconsolePartition check: ubda: unknown partition tableInitializing stdio console driver
02:32 < caker> use the first one I gave you, and make sure you've got a getty listening on tty0 in your UML's /etc/inittab
02:32 < caker> that will fix it
02:39 < clever_jeff> ahh, i found it...inittab was referencing ttys/0 instead of tty0 .... 
02:39 < clever_jeff> thanks a bunch man...really appriciate it
02:39 < caker> np!

03:43 < com4> to answer my own question from a few hours ago
03:43 < com4> you have to compile allowing nat on the nat box in the netfilter options

05:31 < rob> morning all
05:33 < AquaJo> moin
05:34 < BB> morn
05:35 < rob> back to work on my UMLs after my holiday, still haven't found an ideal way of policing their bandwidth :/
05:41 < wojci> rob: You can do QoS with linux .. that is not enough?
05:42 < rob> that's more traffic shaping, I'd prefer it if I could have real rate limiting, like you can get on the Cisco routers. Im not sure if its possible though in the way that I want to do it
05:44 < AquaJo> isn't there a shaper for linux
05:45 < rob> there are plenty of shapers, I want policing though
05:45 < AquaJo> you'll route the traffik through the shaper and everything will be fine
05:46 < rob> hmm, so with that approach, I understand that I can't tell it that it can't have more than 1mbit
05:52 < AquaJo> I have understood ist so, the UML can't make more than x k/MBit traffik
05:53 < AquaJo> a ddos of cource could fill up the connection to the server, and the uml would only get x k/Mbit
05:53 < rob> I think its all in the way that the traffic is limited, there's a good cisco document on it, I can;t find it at the moment

15:35 < frediz> Hi
15:35 < frediz> me again :)
15:35 < frediz> Ive build a gentoo file-system, but booting uml on it, this what it says :
15:35 < frediz>  * Mounting proc at /proc...Child 32152 exited with signal 11
15:36 < caker> whoa -- what UML kernel are you using?
15:36 < frediz> 2.6.0-test2
15:37 < caker> I have no idea then -- does UML even work with 2.6 yet?
15:37 < frediz> Yep
15:37 < frediz> I successfully run it on a Debian fs (dled on sf.net)
15:37 < caker> well here's a dumb question -- is there a proc option in .config even? 
15:37 < caker> ie: can you even turn proc off? (I don't think so ..)
15:37 < frediz> CONFIG_PROC_FS=y
15:38 < frediz> should I turn it off .
15:38 < frediz> ?
15:38 < caker> No, was going to ask if it was on :-)
15:38 < frediz> :))
15:39 < caker> is there a /proc folder inside your uml fs?
15:40 < frediz> yes
15:40 < frediz> drwxr-xr-x    2 root     root         4096 Aug  7 04:23 proc
15:41 < caker> did you forget something, like the "mount" binary?
15:41 < frediz> -rws--x--x    1 root     root        95512 Aug 10 19:39 bin/mount
15:42 < caker> tried booting into single user mode and trying it manually?
15:42 < caker> I think single mounts proc, too, not sure..
15:43 < caker> gotta run, good luck
15:43 < frediz> thx for your help caker 
15:43 < frediz> Ill try that
15:43 < frediz> the kernel option for single mode ?
15:52 < BB> just put single on the startup line
15:53 < frediz> ok thats the same pb...

16:45 < caker> frediz strace the uml kernel
16:47 < frediz> too late, Ive formatted root_fs :)
16:48 < frediz> should /proc be empty  ?
16:48 < caker> Yes, before you mount it
16:48 < caker> I think it is something with your kernel (but that's just my guess) ... it shouldn't exit
16:48 < frediz> mmm
16:49 < frediz> In fact keeping the same .config but changing the way I built the root_fs
16:49 < frediz> things go further
16:49 < caker> same .config between 2.4 and a 2.6 kernel?
16:49 < caker> hmm
16:49 < frediz> nope same .config and 2 differents root_fs
16:50 < caker> weird :-)
16:50 < frediz> yep
16:50 < caker> strace might still help you, next time ..
16:50 < frediz> yes, thx

18:04 < zanshin> hello everybody...Does anyone know if the test series of uml work with a different root filesystem. If I try a 2.4 uml it works with the filesystem and a test2 uml doesn't.

18:06 < frediz> "test series" ?
18:07 < frediz> what do you mean ?
18:08 < BB> 2.6.0 test2 at a guess
18:08 < zanshin> yes
18:09 < zanshin> NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.

18:09 < frediz> zanshin: yes it works
18:09 < zanshin> 2.4 which I downloaded works fine
18:09 < frediz> zanshin: add : root=/dev/ubd/0
18:09 < zanshin> well why do I get this error
18:09 < zanshin> k
18:10 < zanshin> grrrr thanks 
18:10 < zanshin> It works :0)
18:10 < frediz> :)
18:10 < frediz> got the same with 2.6test2
18:11 < frediz> Im now trying to configure the network now but after ifconfig
18:11 < zanshin> well thanks anyway. Now I can start experimenting :)
18:11 < frediz> :)
18:11 < frediz>  ping 192.168.1.25

18:12 < zanshin> routing table?
18:12 < frediz> mmm its said to use : ifconfig eth0 192.168.1.25 up
18:13 < frediz> and give eth0=ethertap,tap0,fe:fd:0:0:0:1,192.168.1.2 to the kernel
18:13 < frediz> tap0 is brought up in gkrellm
18:15 < zanshin> dunno...I just got this up. So that wil be the next thing I gues.
18:16 < frediz> :) let me know
18:16 < zanshin> I will :)
18:23 < frediz> One question before going further :
18:23 < frediz> should the host's kernel be patched ?
18:23 < G2> can grsecurity be used with uml?
18:23 < frediz> G2: simpler one :)
18:24 < G2> No sorry. Hard ones are all I've got
18:24 < G2> :-)
18:24 < frediz> ;)
18:24 < G2> Brad Spenlger says it's hard, so I won't bother then.
18:25 < G2> Spengler
18:25 < frediz> My original kernel dont need special patch or so (except skas which is not mandatory)
18:25 < frediz> ?
18:25 < frediz> doesnt
18:25 < frediz> grrr
18:26 < G2> What are you trying to say here?
18:26 < frediz> yes sorry... a bit messy 
18:27 < frediz> Do I need to patch my host's kernel in order to run an uml ?
18:27 < G2> no, just compile uml or get the rpm dep and ./linux
18:27 < Jax> there is a skas patch that makes it cleaner, but uml will run without it
18:28 < frediz> fine
18:28 < G2> off to bed now
18:28 < G2> later guys

21:23 < clever_jeff> I feel stupid, eveytime I'm in here, I'm the only one asking any questions, but here's another if anyones listening:
21:24 < clever_jeff> during my uml kernel compile, I get:
21:24 < clever_jeff> make: *** No rule to make target `/usr/src/uml/linux-2.4.20-r1/include/asm/vm86.h', needed by `/usr/src/uml/linux-2.4.20-r1/include/asm/processor.h'.  Stop.
21:34 < Jax> this is when you run make linux ARCH=um?
21:36 < clever_jeff> correct
21:37 < Jax> did you do make ARCH=um <someconfig option>, like make ARCH=um menuconfig
21:38 < Jax> i haven't played with kernels much, but I have gotten that before when I tried to compile a kernel without running through a config
21:38 < clever_jeff> host system is gentoo, however, when I emerged the usermode-kernel, it didn't appear to apply the patch (ARCH=um would say no target), so I manually applied the patch 'bzcat patch.bz2 | patch -p1' and make menuconfig ARCH=um worked
21:38 < clever_jeff> (obtained path directly from /usr/poratage/distfiles, it downloaded, but didn't apply)
21:39 < clever_jeff> yes, I did a 'make menuconfig ARCH=um'  and it ran fine
21:39 < clever_jeff> s,path,patch
21:43 < clever_jeff> also, has anyone ever heard of someone using the SELinux kernel patches with UML?
21:50 < caker> will a 2.6 UML kernel utilize skas in the host?
