I feel your pain :-) We used to have the same problem adding new admins to 87 machines. Now we have a bespoke provisioner that does it all. Sorry, I just do not get 'bespoke provisioner'. Some sort of software, like clusterssh? Or a person, one admin instead of many? What do you guys think about using Gentoo for servers? At the institute I partially work we chose Fedora. There is no special reason for that - we already had some Fedora machines, the setup seemed to work, the reputation was good, so we kept it. That was okay for me, why choose many different environments and learn everything again. I mentioned Gentoo, but did not really suggest to actually use it. Maybe I should have. I'm a huge fan of Gentoo Now who would have thought of that! and all my personal machines (except the new netbook have run it for the last 5 years. But I will never install Gentoo on a production server at work. Why? Because it is too time consuming, because no two machines are set up the same, because I can't trust that other admins used the flags they should have. So updates become a case of logging into 80+ machines individually and doing emerge world by hand. Gentoo allows you to customize things to the nth degree - that is it's strength - so people WILL use this one discriminating factor. If OTOH I had a server farm of 80+ machines, all identical, I'd put Gentoo on them in a flash. But I don't have that Of our 8 machines, 7 are essentially the same and differ only in hard drive space and CPU speed. The other machine is Intel, not AMD, and needs different IDE drivers. At the moment it has a different initrd (I set up a minimal fedora install to generate it after the cloned system did not boot), the rest is - apart from some config files - identical. So I would make sure that about everything is exactly the same, well, maybe except for hostnames, udev net-persistent-rules, ssh keys... what more? The last, a little different machine is a problem though. With optimized CFLAGS, this one would have to compile all stuff again, while for the others I could use binpkgs. Updating them all with clusterssh should not be much more work than updating a single one. Well, not completely true, I would have the double work, as I would upgrade one server first to test if there are problems, and then do it for the others. Maybe I could use the special machine to test stuff, and then update all the others. If they would differ, Gentoo would of course be too much work. I already have this problem now... there is my desktop machine, my notebook running a Gentoo VM, a second desktop machine at my other home, the living-room machine of my flat share, the machine of a fried I also administrate, the server of my flat share I need to set up again... and clusterssh is no option here. My potentially ill informed thoughts on the above issues/ideas: 1) Pick one machine to host both your make.conf as well as your portage tree and distfiles, potentially splitting them into separate nfs mounts shared out for the rest of the hosts (having the portage tree itself ro on all but its owning machine forces centralization of syncing). 2) /etc/make.conf should simply be a symlink to the centrally located copy. If you must use binpackages, set march to something that will run on every machine involved, then set mcpu to whatever machine is most common if you want to get just a bit more performance here or there. If you don't mind compiling on every host, though, set portage niceness to something friendly to your users and march to native (if you plan to use distcc, this is a BAD idea, use the binpackages). 3) use a replaceable (otherwise identical to the others, and therefore able to be brought back online by just cloning it over) system for your testing and keep frequent scheduled backups of whichever system plays host to your portage tree, binpackages, and distfiles. 4) build your kernel with built in drivers for every piece of boot-time essential hardware in your systems. You'll still be on a far cleaner setup than a mass produced distro provided kernel, you'll only need to maintain one for all your systems, and you'll only have one kernel to worry about building against if you need any out-of-kernel modules as well. 5) script the changing of ssh host keys (or even redistribution of them, if you ), removal of persistent net rules, and prompting for the setting of host name and you'll have a nice, tiny, postinstall tool for the rare

Why are you trying to do it by hand? Just use emerge and let portage take care
of all the housekeeping for you:
- emerge module-rebuild

- point /usr/src/linux at the source for the kernel you want to build for

[gentoo-user] Re: Gentoo for many servers
Alex Schuster wrote: Alan McKinnon wrote: clusterssh will let you log into many machines at once and run emerge -avuND world everywhere This is way cool. I just started using it on eight Fedora servers I am administrating. Nice, now this is an improvement over my 'for $h in $HOSTS; do ssh $h yum install foo; done' approach. You could have a look at app-admin/puppet [1][2] which supposedly takes car of these things. [...] Now I am thinking about a Gentoo installation instead. Pros: - Continuous updates, no downtime for upgrading, only when I decide to install a new kernel. This is really really cool. I fear the upgrade from Fedora 10 to 12 which has to be done soon. - Some improvement in speed. Those machines do A LOT of numbercrunching, which jobs often lasting for days, so even small improvements would be nice. - Easier debugging. When things do not work, I think it's easier to dig into the problem. No fancy, but sometimes buggy GUIs hiding basic functionality. These two things would probably be your best selling points for your idea. - Heck, Gentoo is _cooler_ than typical distributions. And emerging with distcc on about 8*4 cores would be fun :) Being 'cool' doesn't count, at least last time I looked. - I am probably the only one who can administrate them. That is a huge disadvantage. Cons: - If something will not work with this not so common (meta)distribution, people will say always trouble with your Gentoo Schmentoo, it works fine in Fedora. Fedora is more mainstream, if something does not work there, then it's okay for the people to accept it. - I fear that big packages like Matlab are made for and tested on the typical distributions, and may have problems with the not-so-common Gentoo. I think someone here just had such a problem with Mathematica (which we do currently not use). [...] If you're using commercial software which is only supported by Redhat, Novell, etc. then you should think twice about replacing it. But I'm guessing that those packages don't have to be installed on every machine. So, I'd suggest that you use Gentoo on those boxes where you'd have the biggest advantage using it and no or minimal disadvantages. - I am probably the only one who can administrate them. I think Gentoo is easier to maintain in the long run, but only when you take the time to learn it. With Fedora, you do not need much more than the 'yum install' command. There is no need to read complicated X.org upgrade guides and such. [...] Please do your colleagues and successors a favor and document your whole setup really good.

That doesn't make foul-ups due to such unnecessary meddling any less frustrating, though. My experience has been completely the opposite, same with just about everyone else I work with. But, this is a third-world country pretending to be a first- world country, and the cowboy attitude is very prevalent here. I certainly have had some customers like that, but generally they're a minority here. Definitely preferable is to spot them early and _follow your instinct_ to ditch them. The longer you entertain this rubbish the more of a headache it becomes. One has to hope, really, that the client only wants the root password as insurance in case you get run over by a bus, and won't use it to arbitrarily mess about on the system. I find the root password in a sealed envelope in the safe is the ideal insurance for that. Totally agree. My biggest customer, unfortunately, has taken on a large investment of capital recently, resulting in a new director who's really pretty clueless. Basically, his dad bought him a job. He has insisted on Domain Administrator rights because he just wants to do the simple stuff himself; the first program he wanted to upgrade he needed my help with because the installer is a piece of junk. I know that he's going to mess things up and cost himself more money (create more hassles for me) in the long term, but he won't hear it and I can't just walk away; this is not only because I have a great relationship with the other owner and also because they're currently a significant proportion of my annual income. He's totally a nice bloke otherwise, he just feels that I shouldn't be locking him out of his own computers, and I can kinda see his point - as an admin it's easy for me to feel territorial because I'm pretty good at the job, so the chances are that anyone else isn't going to meet my standard. Obviously it's important for me to put that to one side. So when he fucks things up good royal and proper, will he gladly accept his shafting and pay you more to undo it? Or will he do the usualcustomer stuntand blame you? This is actually much easier for those of us who are mere consultants and who charge by the hour - we can simply reply it was working when i left, guv. If it's been working fine for months then there is obviously nothing wrong with our previous work. Clearly there is room for contention if they muck about with things right after you've left.

It's much easier, and much more secure. fail2ban and/or denyhosts is still very useful with key-only auth, even if only to get the spam out of messages and into the iptables logs I've hardened ssh by doing the following: * Only allow certain users to ssh * Not allowing passwd login, but only RSA * Switching ssh to a non-standard port This has dramatically reduced the amount of attacks my box gets. It's down to about 2 attacks per year, which is good enough for me. Another trick I learned about, but haven't implemented is changing the version string in sshd by patching the source. Ssh vunarability attacks actually check the version string, so if you change it to something unique, the scripts won't even try to get into your box.

James Ausmus wrote: [snip] First off - do you have PulseAudio running? If so, for HW/ALSA testing purposes, shut it down. Second, check your mixer settings to determine No I don't have it installed. if your volume levels are appropriate. A great quick CLI app for this is alsamixer (media-sound/alsa-utils) - first start the alsasound service (sudo /etc/init.d/alsasound start), then run alsamixer - set your volumes to about 80%, and unmute all channels (use the 'm' key to toggle mute), then restart the alsasound service to save your volume levels (sudo /etc/init.d/alsasound restart), then add the alsasound service to your boot runlevel (sudo rc-update add alsasound boot). This will set it up to restore these volume levels on every startup (it will also save your *current* volume levels on every shutdown, so don't mute, shutdown, and expect to be unmuted after starting back up). Followed all steps after emerging alsa-utils Now, double-check that PulseAudio is not running (ps -elf | grep -i pulse), and kill it if it is.
