Hi Frank and Mike, Ok, I believe I see the light now Frank. Finally... Heh... Frank With your previous explanations I see now that I don't need to use the "FORWARDONLY" variable. Sorry it took so long. So now to use dnscache to soley do resolving instead of forwarding on behalf of the clients requests I just need to reconfigure my setup via the following: Please let me know if this is correct?? Remove the sym linked /service directory. And recreate after performing the following steps?? Should I stop "svscan" first before performing the above and below steps?? 1) Remove the the "FORWARDONLY" variable that I created intially??... when I did echo 1 > /etc/dnscache/env/FORWARDONLY 2) Repopulate /etc/dnscache/root/servers/@ with previous list of root servers before I removed them and added the one ip of the isp dns server? Umm..where do I get this list of ip's now that I have removed them?? I do notice that I have a file /etc/dnsroots.global that lists the following ips. 198.41.0.4 128.9.0.107 192.33.4.12 128.8.10.90 192.203.230.10 192.5.5.241 192.112.36.4 128.63.2.53 192.36.148.17 198.41.0.10 193.0.14.129 198.32.64.12 202.12.27.33 Can I just cp this list of ip's to /etc/dnscache/root/servers/@ ??? 3) Recreate /service directory: ln -s /ect/dnscache /service sleep 5 svstat /service/dnscache How's that look??

Dnscache does a good job in resolving itself. So there is no need to forward to another server (special setups may *require* forwarding, but not in your case). So you simply let dnscache talk to all required dns servers itself instead of asking for help at the ISP's servers (that's called forwarding). > > So you don't use the core function of dnscache.

I think I can see your point of confusion. When talking about forwarding you mean the resolving that is done by dnscache on behalf of the stub resolvers at the clients. Explanation: nearly no clients contain a full blown resolver. They rely on a resolver that answers recursive queries. Such a resolver may be dnscache or the dns servers (caches/resolvers) at your ISP. But forwarding in context of dnscache means that dnscache doesn't do resolving - instead it relies on the resolver service of the ISP. > > > When I rebooted "svscan" didn't start at boot which I find a little > > > strange so I guess I need to add this to the default runlevel with > > > the "rc-update add svscan default".

Yes this is the latest stable ebuild that came with the patch. I didn't know that the patch was included at first until you told me where to look. I suppose if I had been watching the emerge compile process at the time of compilation then I would've noticed.

Re: [gentoo-user] DJBDNS and Gentoo linux
Hello Frank, Where are you getting this info?? And why would someone not want to use forwarding? You made the comment that forwarding isn't reccomended but don't say why. I have a forwarding cache setup right now and it works like a charm. It talks to one up stream dns server at the isp and works fine. But in my case I think this is just forwarding the client dns request's like normal. Maybe your talking about TinyDns?? NO..?? I'm a little confused here. :P I installed "djbdns" strictly for the ability to act as a caching server as well as a dns forwarding agent that the other pc's point to when making dns requests. I followed this doc and this works exactly as I envisioned wanting it too http://cr.yp.to/djbdns/run-cache-x-home.html The only things that I have found different from whats on this doc is the fact that when I emerged "djbdns" or "daemontools" it created the following accounts for me transparently which was a little confusing at first because the doc want's you to creat "Gdnscache" and "Gdnslog" accounts. So I just skipped that part. dnscache:x:1001:200::/nonexistent:/bin/false dnslog:x:1002:200::/nonexistent:/bin/false tinydns:x:1003:200::/nonexistent:/bin/false The other thing that I found was that "svscan" wasn't running so the "supervise" service would never start. Once I "/etc/init.d/svscan start" everything started working like a charm. When I rebooted "svscan" didn't start at boot which I find a little strange so I guess I need to add this to the default runlevel with the "rc-update add svscan default". Sorry for the rant. Just thought it's important to put the info out there. To Mike Williams, You said that I need TinyDns configured to achieve dns caching and forwarding. This is totally untrue. If you're unsure of an answer to a question please don't post to a list given them info that is not correct. This isn't good practice. If you think you know the answer to a persons question but actually don't know for sure, then kindly please say so. This way the person will know to either research more or take your word as gospel.

Nope, tinydns is a dns server, and thus is only able to server the dns records it knows about (the ones you told it). dnscache is what asks the dns server for records, the entries in /etc/dnscache/root/servers/ tell it where to go for those records.

Confusing. Can I just rename these accounts, delete them and then > recreate, or does it matter? Just exchange Gdnscache and Gdnslog for those the ebuild made. As for the setup, I wrote this just this saturday, might help. Right, basic setup. Tinydns listens on 127.0.0.1, dnscache(x) listens on an/the external interface(s). Tiny is the resolver, dnscache the (brainfart moment). My router has it's internal address in /etc/resolv.conf (it's 192 address). Lets do this backwards, starting with dnscache. redshat root # cat /etc/dnscache/env/IP 192.168.0.1 You will need dnscache, and dnscachex. One on the internal that will resolve anything, and one on the external that will only resolve your domain. The files in /etc/dnscache/root/ip/ tell dnscache who is allowed access, in my case redshat root # ls -lh /etc/dnscache/root/ip/ total 0 - -rw---1 root root0 Jul 1 02:43 127.0.0.1 - -rw-r--r--1 root root0 Jul 1 02:43 192.168 I'm pretty sure an @ will allow anyone. To tell it what it is authorative for, and where it go for the resolver put files in /etc/dnscache/root/servers redshat root # ls -lh /etc/dnscache/root/servers/ total 12K - -rw-r--r--1 root root 10 Jul 1 02:43 0.168.192.in-addr.arpa - -rw-r--r--1 root root 164 Jul 1 02:43 @ - -rw-r--r--1 root root 10 Jul 1 02:43 home.gaima.co.uk redshat root # cat /etc/dnscache/root/servers/0.168.192.in-addr.arpa 127.0.0.1 redshat root # cat /etc/dnscache/root/servers/home.gaima.co.uk 127.0.0.1 redshat root # cat /etc/dnscache/root/servers/\@ 198.41.0.4 128.9.0.107 192.33.4.12 128.8.10.90 192.203.230.10 192.5.5.241 192.112.36.4 128.63.2.53 192.36.148.17 198.41.0.10 193.0.14.129 198.32.64.12 202.12.27.33 Reverse for 192.168., forward for home.gaima.co.uk, and for anything else pick a root server (default config I think). Now to tinydns. redshat root # cat /etc/tinydns/env/IP 127.0.0.1 It only listens on localhost. Now all you need is the data. A nameserver .home.gaima.co.uk:192.168.0.1:redshat.home.gaima.co.uk:259200 Another nameserver .0.168.192.in-addr.arpa:192.168.0.1:redshat.home.gaima.co.uk:259200 An A record, with PTR =redshat.home.gaima.co.uk:192.168.0.1 A CNAME Cmrtg.redshat.home.gaima.co.uk:redshat.home.gaima.co.uk:86400 An MX @home.gaima.co.uk:redshat.home.gaima.co.uk:redshat.home.gaima.co.uk You'll have to read Dans docs on the data format, I can never remember :) HTH > I'm not new to DNS, networking and firewalling, but new to how these things > are done on Linux.

[gentoo-user] DJBDNS and Gentoo linux
Hello, Gentoo Automatically created 3 accounts when I emerged "djbdns". The following where created: dnscache:x:1001:200::/nonexistent:/bin/false dnslog:x:1002:200::/nonexistent:/bin/false tinydns:x:1003:200::/nonexistent:/bin/false The djbdns docs wanted me to create "Gdnscache and Gdnslog" system accounts. Confusing. Can I just rename these accounts, delete them and then recreate, or does it matter? I'm not new to DNS, networking and firewalling, but new to how these things are done on Linux. I've read through the djbdns doc's and need a little confirmation from the linux pro's. I have Gentoo linux installed on a PC that acts as the firewall and defaultgateway for the other 3 pc's on my lan doing NAT and basic packet filtering. Right now the Gentoo Linux pc dials-up to the internet to get its ip via dialup ppp0. This connection is then shared among 4 pc's. I know..slow but this is all I have and it works fine for now. The ip that I get every time I dialup is different but the dns server ip's are inputed statically in KPPP's dialup tool. So everytime I dialup /ect/resolv.conf is popultated with two dns entries temporarily while dialed up. What I ideally want if for the other 3 pc's that use the Gentoo linux box as their default gateway to also send their DNS requests to this box as well and then the Gentoo linux box would do the lookups on behalf of the client and then return the requested info to the client doing the request or have the requested info already cached. Give the description above of what I'm trying to do and the choices given below from: http://cr.yp.to/djbdns.html , I'm alittle confused as to which one does what I'm trying to do. Logically I think #5. Is this correct? 1. How to run a cache on a workstation 2. How to run a computer without a cache 3. How to run a forwarding cache on a home computer 4. How to run an external cache for your network 5. How to run an external forwarding cache My other question is about following some of the directions listed: 1st question. Quote: "1. As root, create UNIX accounts named Gdnscache and Gdnslog." Unquote: So form the command line as root am I just creating the above "user accounts" without passwords?? 2nd question. Quote: "3. As root, create an /etc/dnscache service directory, with your IP address on the end of the line: dnscache-conf Gdnscache Gdnslog /etc/dnscache 10.53.0.1" Unquote: So from the command line i just need to create the directory "dnscache (my ip-address)?? My example: mkdir /etc/dnscache 192.168.1.1 This creates the dnscache directory but I don't see 192.168.1.1 referenced or associated with the "dnscache" directory created??? But then I'm totally confused with what the heck the following is?? dnscache-conf Gdnscache Gdnslog /etc/dnscache 10.53.0.1 Is this a command or do they want me to make "dnscache-conf", "Gdnscache" and "Gdnslog" directories under the /etc/dnscache ? The lingo or symantics used have me very confused through out this entire document? I don't understand what this means in laymens terms either. Quote: "4. If your computer is running a DHCP client to obtain a dynamically assigned IP address from your ISP, configure the DHCP client to make external DNS cache information available to dnscache, and skip to step 8." Unquote: Well I'm using PPP to dialup to get an ip. Sorry. I've never heard anyone use this type of terminology before. I have know idea what it means to configure a DHCP client to make external DNS cache information available to dnschache. I know what dhcp is and does but have no clue what the author is asking here.
