[gentoo-server] eth0 startup

[Ajai Khattri]

I have iptables and net.eth0 in my default runlevel - is it normal for 
iptables to start *before* eth0 is up? If not, then why is this happening?

I think it's for security reasons. If eth0 goes up first and the 
iptables some (short) time after that. Then in that (short) time some, 
perhaps malicious, could come in. Which should be blocked be some 
iptable rules, that still have to be loaded.
That time should be pretty short, but better safe then sorry, so 
iptables is started first.

This is happening to make sure your firewall rules are in place *before*
you accept any traffic. So yes, it's normal

RE: [gentoo-server] Questions about Server

[Spahn, Daniel]

Is this project about how to configure Gentoo as a server OS, or is it about creating a branch of Gentoo dedicated to being a server? In either case, I have some suggestions...

One of my pet peeves about emerging for a server-grade platform is that there is no way to truly separate the build/install process that is easy to track. I have read about the buildpkg and buildpkgonly options, but I don't like them because they are not geared toward a sys admin that has several machines that may need different packages emerged. In my ideal world, the emerge function could be run with a command switch, which would cause it to run the full emerge without installing, then with a simple command, list all the built packages that need to be 'installed'--- much like etc-update. Before I bring up any more suggestions, I would like to know more about the gentoo-server project's angle. Can someone point me in the right direction?

Thanks.

First pointer I would give is not to hijack threads, start a new one.

Actually, it was originally the latter, but that project failed long ago due to 
lack of time/interest on the part of the people working on it. It's basically 
become the former.

RE: [gentoo-server] Emerging for servers

[Spahn, Daniel]

Is there an app or script that I can use to emerge up to the point of compiling, without installing or completing the merge, track the packages that were compiled, and run a batch install of the compiled packages, collecting the package-specific notices? If not, can someone point me to a good scripting resource? I don't know a lot of shell scripting yet, so I need a basic and intermediate tutorial... Thanks!

step1: emerge -B pkg1 pkg2 pkg3
step2: emerge -K pkg1 pkg2 pkg3

But there problem with this: if pkg2 DEPEND on pkg1, then it either will
not compile at all (without installing pkg1 first), or, worse, it will
compile using older, currently installed version of pkg1, and after
installing at step2 pkg2 become broken (because pkg1 was replaced by newer
version without recompiling pkg2).

You would of course want:

FEATURES="buildpkg"

in your make.conf

Thank you- that's very helpful. Is there a way I could track the packages, or would the list simply bee the tree structure of ROOT (below)? Thanks!

ls $PKGDIR outside of the chroot.

If you don't want the resultant $ROOT you can just blow it away.

A possible architecture would be to have a development server (where
Gentoo is used as it is used mostly, i.e. source-builds, but with a
somewhat static portage tree), then a staging server with
FEATURES=buildpkg, then a testing server where you only install the
binaries (which were created on the staging server) and if the testing
is succesfull, proceed with the production server.

Of course, that would require some resources although virtualization
can help you a great deal.

Wkr,

We actually pull upstream portage into a git repository and merge only  
the packages that we need to merge into our production branch. This  
also allows us to test incoming packages for various levels of breakage.

We use a dedicated build system to compile the binaries used by our  
systems.

My apologies. I had not realised that, as that would be a project I
would be interested in. 

I had been considering an overlay based structure, but never got very
far with my thinking.

I'm not much of a coder, but I'll help how I can. I have a couple of servers running Gentoo, and plenty of ideas.

Well, there generally isn't a shortage of ideas, but of people actually
implementing them (as that's the boring and time-consuming part).

I'm not very good at raw coding, but I am good at picking up something pre-existent and modifying it to suit my purposes. I'm still trying to get the hang of overlays, though.
