I seem to be pretty much on my own, here. I use Gentoo on a single desktop computer at home, mainly for developing free software (Emacs). I've configured the PC with two HDDs in RAID-1 (mirrored), and I run logical volume manager. I keep the box aggresively up to date, synching portage almost every day. One of these days, I'll get around to installing Gentoo on a dusty old laptop I've got. > -- > :wq Alan Mackenzie (Nuremberg, Germany).

You might also adjust your resolver's searchlist, so that you can still resolve short names on a different domain. For example, I might add "slashdot.org" to my resolv.conf as a search domain, and then I could point my browser to "http://yro"; or "http://linux"; and land on yro.slashdot.org or linux.slashdot.org, respectively. Note that resolv.conf is typically rewritten by your DHCP client, so any modifications you'd like to persist, you'll need to make in your DHCP client's configuration. I believe the normal resolver only supports up to three search domains, too, so if your network's DHCP server is already pushing three search domains (the network where I work should be pushing two right now, for example), the fourth in the list will be ignored. -- :wq

Obrigado, Francisco ! Foi uma falha minha mandar em portugues na verdade queria mandar para gentoo-user-br mas me enganei.

Pergunto, quando o git 1.7.6 estiver considerado estavel o comando emerge --update --deep --newuse world vai atualizar para essa versao ou vai manter em outra atualizando apenas patchs de seguranca ?

FWIW I have experienced that same behavior with several PS/2 to USB adapters, in Windows, in Linux, etc. I think it's a common problem with those adapters in general.

Re: Re: [gentoo-user] atualizacao do gentoo
Na verdade também tive uma falha, não se deve responder acima da pergunta, só abaixo, que é o que diz as normas de listas. Mas já que está feito... Assim que os pacotes vão sendo liberados do "~", saindo, por exemplo, do "~x86" para "x86", a atualização vai mesmo substituir a versão antiga pela nova, com todos os seus patches também novos, ou seja, no seu exemplo, a versão 8.4 é removida e é instalada a 9.0. A atualização de patches de segurança acontece sempre que necessário nos pacotes. De vez em quando, quando você solicita uma atualização, eles são aplicados e uma reinstalação é feita. O "portage" é fantástico. E o comando emerge --update --deep --newuse world pode ser resumido em emerge -uDN world . Dê uma olhada no manual para mais opções.

Or in other words: Adding these resistors seem to fix the problem in most cases. See the link below (which describes the process for a IBM Model M keyboard. Seems true for other old PS2 keyboards as mine, too): http://ps-2.kev009.com:8081/ohlandl/keyboard/modify_keyboard/Model_M_Modifications.html The PS2 goes crazy because the high level gets too low without the additonal pull up resistors. But the "origin of the reason" is not the adapter, but the low high levels of the old PS2 line as such. I did find these information that late (after posting to this list) by searching for informations about certain different usb-PS/2-adapter. Sorry, when answering the other half of my own question :)

In /etc/layman/layman.cfg, you can also specify a proxy. In theory, that should allow you to fetch all these overlays. The remaining problem is: How do you tell layman to prefer the http connection over the native protocol? I haven't found such an option.

[gentoo-user] systemd
Ok then, separate thread ;-) I just watched this: http://www.youtube.com/watch?v=TyMLi8QF6sw while I continued testing systemd in my VM. The VM runs ~amd64, so far only a few services started (I still get my head around how to enable/disable specific services/targets), and it boots really fast. I am not the ricer-kind-of-gentoo-users, but it impresses me anyway. And I clearly see the benefits of socket-based-activation, cgroup-control and other stuff systemd brings. AFAI see the wiki mentioned is a starting point only. It provides the first steps, but not much more, at least to me, right now. - There is a layman-overlay "systemd" which brings units (service-files) to your system. AFAI understand it is still up to the user to enable/link these files into their runlevel? If it is that way it feels like a bit of trial-and-error to me to get my systemd-setup doing the same things my current openrc-system does. Especially for not-so-trivial stuff like the network settings for KVM (bridging, TUN/TAP ...) My approach would be to "rc-config show", take that list and try to enable the according services within systemd. Maybe I am completely wrong, maybe not. I'd be happy to discuss these things with you gentoo-users. Thanks, greets, Stefan

I haven't administered bind on Gentoo, but on Debian, most of the problems I run into come from how Debian packages and updates configuration files. I'm not running DNS servers in any major production capacity; I've got a bind server at home linking my home domain and my employer's work domain across a VPN, and updated dynamically via a dhcpd on the same server. It's also serving as a caching recursive resolver for my home network, which was *really* necessary when I was still on AT&T. (The DSL link was dropping packets every now and again, and it's a PITA when that happens to DNS queries) If you want to get into managing your own DNS, and if there was anything in that previous sentence you're unfamiliar with, I highly recommend O'Reilly's DNS & Bind: 5th Edition before you commit any of your services to your own server. http://oreilly.com/catalog/9780596100575 -- :wq

Yes, in fact it's exactly the same. Unicomp was formed by former IBM/Lexmark employees who bought the original Model M manufacturing equipment and rights to the original designs and parts from IBM. So it's very much the same as Model M but available with updated with modern features like USB and windows keys (if desired) and different colors. They are still manufactured in the US at Unicomp's offices and not outsourced to China or anywhere like that. USD $80 seems like a lot of money for a keyboard to some people I talk to, who are used to getting the crap $5 rubber keyboard from the computer store. :) but if you spend every day typing, like I do, it's really a small amount to pay. I've been using mine for a few years now and am extremely happy with them. I have the original huge one (the "Customizer") and the smaller one with a trackpoint mouse in the middle (it's smaller but still heavy and clicky, using the same spring mechanism as the big guy).

But there's this little thing called an NDA and it says I can't :-( Truly though, the devastation from DNS mistakes is horrendous. The primary error folk make is this: You do not configure and treat the DNS service like any other service. You do not USE the internet to maintain dns, as dns BUILDS the internet. It's a subtle distinction but a vital one. -- alan dot mckinnon at gmail dot com

This I don't know. I use this value for large partitions of multimedia data, because I do not want to waste space (no matter how big the drives are, mine are always quite full), and performance should not be a big issue here. I keep the 5% default other partitions, like /home. BTW, you can also specify fractions like 0.5% if you like. Another thing: Be sure to have enough inodes on the file system, I have run out of them in the past. Not only once. Other than the percentage of reserved blocks, which can be changed with tune2fs -m, this value is fixed. If you have too few, you need to re-create the file system. Wonko

Way back when ext2 was being developed, 500M drives were big. 5% reserved is 12.5M or about 12,500 blocks. Why that amount? Is it really 5% or is it the number of blocks and 5% just happens to round that out nicely? Median file sizes haven't changed much in 15 years. The number of files on an average machine has increased hugely, and the upper size limit is orders of magnitude bigger, but that doesn't affect the median size much. I take the view that 5% is excessive these days and usually reserve only a tiny amount - something like 10 x the biggest file I expect to have to deal with when the disk is full. And besides, as Murphy would have it, it's usually a root process that fills drives anyway (syslog cough cough) rendering the reserved amount useless :-) -- alan dot mckinnon at gmail dot com

But there's this little thing called an NDA and it says I can't :-( heh, I think I can dredge one up for you that no one will care about these days. This was at a large ISP in '99 known for their free Internet. Bind 8 was fresh on the scene and somehow Network Engineering was in charge of DNS rather than Systems. My intern and I came up with a plan to have ns00.int as the internal master and make the rest of name servers slave off of it. All ns00 did was supply the production name servers with zones. ns00 --> ns01(vip) --> ns01-[01-03] \--> ns02(vip) --> ns02-[01-03] \-> ns03(vip) --> ns03-[01-03] Three virtual IPs and three name servers behind each vip. This way we could have tools deal with updating zones on ns00 on the internal network and not have to push to a number of name servers. This worked well for a few months and we generally forgot about it. Almost a month after a reorganization in the local datacenter DNS went down. Well not down down, but our zones weren't working. After a hectic hour of freaking out, troubleshooting random things, and bouncing from machine to machine by IP address because none of DNS worked we realized our mistake. The TTL of the zone itself was set to three weeks. In the move Bind had silently died on ns00 which we didn't monitor because it was inside the corp network. The slaves dutifully stayed up and working till they hit the TTL of the zones and demanded to speak to the master again. Restarting Bind on the prod servers did nothing other than remove the already expired cache. Once restarted Bind on ns00 (and made it part of the runlevel) the prod server checked in and all was well. The lessons: Monitor *all* of your DNS infrastructure DNS can break even with a large distributed system and it is never pretty. kashani

Don't be too put off, it can be a good learning experience depending on how critical your domain is - some things don't matter if they are off-air for a week. The most valuable lessons you will ever learn are the ones where you then know what you should not do :-) I can't advise on any free providers as a) I'm far away in a place that has nothing in common with your location and b) I've never interacted with any of them.

I'm glad you detailed that story, now I know I'm not the only one :-) Long long ago (in the 90s) when a current colleague started working here, he wanted access to the hidden primary (like your ns00). He was given a bare machine (no OS) with these instructions: It's 10am, by 4pm I want a name server running on that hardware, authoritative for domain xxx.yyy.zzz, live on the internet, with firewall installed and all reasonable security precautions taken. You do not have to register xxx.yyy.zzz with any registrar, we will test it with "dig @". He passed :-) The same fellow 3 years later found one day that the company zone had not loaded after an update (the name servers are self-hosted in that zone) and the support person that did it had done it twice before recently. Ten minutes later an ACL was in place and only systems could edit the zone. The entire company was told to propose sub-domains for their own teams and systems would delegate them - the uproar was fantastic but he stood his ground. He was 100% right of course and we still benefit today.

Just to counter all of the scary stories, I recently (within the past month or so) installed bind for the first time and set it up after a few days of googling around and reading docs. It seems to be working properly and securely, but I'd be lying if I said there wasn't a large amount of dumb luck, finger-crossing and hand-waving involved on my part to get it working. I have some familiarity with editing DNS zone files (on other people's servers) so I wasn't going into it completely blind. I don't know if I'd call it "fairly trivial", but with howto's and google at your fingertips you should be able to get it set up properly if you really want to. Usually the web-based DNS management by your domain name registrar or hosting provider are good enough for most "personal domain" kind of usage (like mine). In my case there was something that their web-based editor didn't support (TXT records on subdomains or something like that), and mostly because I just felt like trying to do it myself. Since they are my personal domains, nobody else will suffer if I break everything. Others are in the (lucky? not so lucky?) positions of administering systems where things actually have to work right the first time and all the time. :)
Re: [gentoo-user] Running HTTP and DNS on same machine
> Just to counter all of the scary stories, Yeah, i'd like to counter too. While the implications of getting it wrong are serious, technically its quite simple. I run my own DNS, and use a couple of free secondaries (http://www.twisted4life.com and http://www.everydns.net). The upsides of running your own DNS is that you learn the ins and outs. So, if the DNS is for business that will loose money if you stuff it up, then i'll tend to agree with the naysayers, but if its a home domain then go ahead. And if you don't have a home domain, get one as a learning exercise and once you're mastered that you can re-consider if you want to move the business domain. Re: choice of server, I chose BIND as its what the companies I have worked at use, both ISC BIND and QIP's port of it. djbdns may be technically superior (eg code separation into different binaries) but its not as if BIND is very problematic these days. I havent bothered with chrooting BIND for a long time, but that's only on internal only DNS or my home DNS. For business internet facing DNS I probably still would, or use something more modern like Solaris sparse zones.

Re: [gentoo-user] Running HTTP and DNS on same machine
Adding to success stories: I've deployed bind-9 on FreeBSD, Debian, and Arch. The most trouble was with Debian, what with the 'compositing trees' etc. The easiest was with FreeBSD. All three DNS servers are now in their eighth month of production, handling half of my company's NS needs. It's really not difficult. Complex, yes, but not difficult. With the help of http://www.zytrax.com/books/dns and the handbooks, I finished the FreeBSD and Arch installations in one day. (The Debian took another day of hair-pulling to understand HTF they put their compositing files together). One tip from me would be to prepare the DNS servers beforehand, test them, *then* ask the registrar to transfer the domain name to you. Like others have posted, most will require you to provide at least two authoritative NS. In my situation, I have 1 server in the cloud, and 2 servers in the company (responding to DNS requests via 2 different ISPs). That said, I might be installing a different NS for the 4th NS for diversity (i.e., prevent a single attack from disabling all 4 NS servers).

Alan and I would have had a vastly different take on this if it had been phrased as "I want to setup DNS at home for learning and convenience." Instead the email in my mind read as, "I'd like to introduce a single point of failure into my system and I'd like to do it with something I don't fully understand to boot." Yes, I have a rich and cynical inner monologue. This is well known. That said if you want to setup Bind (which I prefer) the Gentoo wiki has a decent how-to. I wrote the original incarnation 7-8 years ago and people have kept it updated. It looks mostly correct though I can see a few places where it needs some clean up. Even with the cruft it is light years ahead of the official Gentoo Bind doc and includes a number of config entries to make troubleshooting and running ISP type name servers easier and safer. http://en.gentoo-wiki.com/wiki/BIND kashani
