Fedora 18 doesn't have ifconfig in the installer (and perhaps not in installed
system), need to use ip.

What branch did you create this against? It did not apply to master.
Can you rebase this against master and resend it?

Found a small problem with this. Apparently despite the fact that the
OS has had the ip command for quite a while, it is not included even
in the F17 installer image. I've attached a patch which uses some bash
functions to figure out which command to use, and wraps the calls in a
nice way. If you could give it a little testing I'd appreciate it
(testing it out on f18 alpha now myself).

I guess that's what you get for assuming - I thought if the EL6 installer had
it, Fedora would have, but there you go.
One note - you are redirecting the output of the ip command, but not ifconfig.
Seems inconsistent.
Anyways, works for me with F17 and F18.

Yeah definitely my bad for not checking the installer had it. Anyway,
my signature branch now has full support for F18 in it, and it's
importing and building systems successfully using the beta TC6 ISO:
https://github.com/jimi1283/cobbler/tree/signature
http://dl.fedoraproject.org/pub/alt/stage/18-Beta-TC6/Fedora/x86_64/iso/
There are still a ton of issues with F18 in general though. Just found
out tonight that they're doing away with the base comps group, so the
sample_end.ks is basically an extremely minimal install that's missing
a LOT of stuff.

Did you ensure this works as expected on older Fedora too? Is it better
to use ifconfig when present (as it's tested) and switch to ip only when
ifconfig isn't there?

I have not tested on older Fedora, but you're using ip already to set the
route, so it is present. And ip on RHEL5 has the -o option, so I think
shifting to ip is the way to go. It's easier to parse.

shifting to ip is the way to go. It's easier to parse.
The ip command has been around for a while, I've used it as early RHEL
4, so this change should work for just about any distro.

Did you use it in the
installer? post_install_network_config snippet is
run on installed system in chrooted environment, so it should not be a
problem. However, pre_install_network_config is run inside of anaconda -
we want to make sure it is available there for the versions that cobbler
supports.

Actually, I've been installing EL6 with it, so it should work with any older
Fedora as well.

New subject: Ideal home test lab setup for testing out cobbler?
I have finally moved to a bigger place. Now I finally have some space to setup a home test
lab for testing various cobbler related ideas. Currently, my new place has AT&T
Uverse Internet service, a 2Wire 3600HGV Router, I have also got a few notebooks and
netbooks as my first set of test hardware. Nearly all of them run Linux (CentOS, SL,
Ubuntu, and Fedora), only one runs Windows XP/Home SP3.
I am sure that I am not the only who want to have a home-based test lab :-) For these who
have gone down this route, do you mind sharing a bit of your setup? I am most interested
in getting some cost-effective hardware for my own "small lab". I have got a
few notebooks. Very proficient in RHEL, Fedora, Ubuntu, and KVM.

New subject: Ideal home test lab setup for testing out cobbler?
Zach,
I definitely do this at home. I suppose you could call it a small lab - but I do more
than test stuff in that I spin up VMs for normal work-level stuff (some tinkering, some to
support my open source projects)...
I do switch servers/hardware around a lot. Lately, I've been on a power-less kick,
trying to utilize the minimum amount of power I can but still do the most with what I have
(and only turn on my power hungry boxes when need be)...
My current setup is:
- DLInk DNS-320 NAS (two 256 GB sata drives). Runs Debian squeeze and is my DNS, DHCP
(internal to house) DDNS box (so my VMs/bare metal can register their names with DNS), NFS
and Samba server. Also is a TFTP server for PXE booting my bare metal.
- Acer Aspire pos (piece of bleep) laptop. Runs CentOS 5.8 centosplus Xen and is my
Cobbler and Puppet server. Also sports a CI VM (CentOS 6.3) (specifically Jenkins) and
sometimes other various low requirement VMs.
- Dell Latitude CPx-something-or-other pos laptop (1.2 GHz model w/ 512 MB RAM). Runs
CentOS 5.8 bare metal mostly for a side display using synergy controlled from my work
laptop (when I work from home).
- Two Dell Precision 470's running CentOS 5.8 Xen centosplus as hosts for VMs - each
has 4GB RAM.
- One Sun 64-bit early generation dual opteron box - running CentOS 5.8 Xen centosplus as
hosts for VMs. Has 8GB RAM.
- Have a P4 box with what I believe is a broken IDE controller. Am looking into doing
diskless boots with it, but haven't spent too much time on that yet...hope to sometime
soon :)
Interestingly enough I am NFS mounting a TFTP dir from my NAS but having Cobbler pos
laptop write out the PXE magic to that dir...
I call it my top-of-the-line server room circa 96 :)
I can spin up a ton of VMs on the "better" boxes. None of what I have supports
full virtualization - I'm stuck using paravirtualization. However, CentOS 5.8 as a
host OS is definitely fine for my needs. Everything also runs puppet for configuration.
I provision all my VMs using KOAN, and bare metal using PXE off the Cobbler pos laptop...

This is actually pretty close to my home setup network-wise. My main
system currently is an AMD 6 core running SL6 (8GB RAM, 1.5TB disks),
which I use to deploy kvm guests for testing cobbler development. Any
system like that should be more than capable of testing cobbler in
basic setups.

New subject: Ideal home test lab setup for testing out cobbler?
Hi
I can't really comment in detail about hardware. For most stuff ram is
probably better to have than CPU in terms of virtualization and fast
storage and/or more or at least one controller card for disks.
I run ESXi 5 and intend to update it to 5.1 which should give me the new
web based admin. Not sure if that is part of esxi. I run all my VMs on two
networks. A private network interconnect between the machines and a
"management" network that allows me to be able to ssh to the boxes that is
connected to a network card and my home router which also does the dhcp.
My pico cent's worth.

I agree, disk space and speed are probably the most important areas to
focus with cobbler. Like a database, avoid RAID5 (stick with 1 or
0+1). Unless you're dealing with 1000+ systems SATA disks should be
sufficient. If you're building a lot of systems simultaneously, more
RAM and faster 10-15K disks would help too, but I doubt that'd be the
case with most lab setups.

Another interesting idea... which might or might not work is to buy a few
raspberry pi s and connect each to a HD and all of them to a fast switch.
Then use Ceph file system to do distributed storage. http://ceph.com/

I agree, disk space and speed are probably the most important areas to
focus with cobbler. Like a database, avoid RAID5 (stick with 1 or
0+1). Unless you're dealing with 1000+ systems SATA disks should be
sufficient. If you're building a lot of systems simultaneously, more
RAM and faster 10-15K disks would help too, but I doubt that'd be the
case with most lab setups.

Talking about shared storage, why not use the HekaFS or GlusterFS (both basically the
same) https://fedoraproject.org/wiki/HekaFS or http://www.gluster.org/. Red Hat owns it,
Fedora has it OOTB. I have tried it at work, and based on my limited experience, it seems
to be decent.
An OT: why this thread is not archived in
the http://www.mail-archive.com/cobbler@lists.fedorahosted.org/? Anyone has an idea?

I run a mixture of kit, briefly as follows:
2 x Intel Atom D525 running Citrix Xenserver (free version) with shared
storage via DRBD
2. x Core i3 running Centos 6.3, KVM and Cluster suite with shared
storage via DRBD
1 x Celeron 1Ghz laptop with 1GB RAM running Fedora 18 xfce destop (runs
very well for me)
My cobbler server is a KVM guest with one virtual CPU and 512MB RAM. It
has worked perfectly fine for me when building guests with cobbler / koan.
Other services I run virtualised are postfix, DNS, NTP, apache, bacula,
squid. I tend to run a service in it's own guest OS (Centos 6).
My home network is GB with a Belkin wireless router.

I run ESXi 5 and intend to update it to 5.1 which should give me the
new web based admin. Not sure if that is part of esxi. I run all my
VMs on two networks. A private network interconnect between the
machines and a "management" network that allows me to be able to ssh
to the boxes that is connected to a network card and my home router
which also does the dhcp.
My pico cent's worth.

I have finally moved to a bigger place. Now I finally have some
space to setup a home test lab for testing various cobbler related
ideas. Currently, my new place has AT&T Uverse Internet service,
a 2Wire 3600HGV Router, I have also got a few notebooks and
netbooks as my first set of test hardware. Nearly all of them run
Linux (CentOS, SL, Ubuntu, and Fedora), only one runs Windows
XP/Home SP3.
I am sure that I am not the only who want to have a home-based
test lab :-) For these who have gone down this route, do you mind
sharing a bit of your setup? I am most interested in getting some
cost-effective hardware for my own "small lab". I have got a few
notebooks. Very proficient in RHEL, Fedora, Ubuntu, and KVM.
