OpenDNS - Treoir Gearr do Usáideorí Debian

OpenDNS - Treoir Gearr do Usáideorí Debian

OpenDNS - Quick Start for Debian Users

Tá na treoracha seo níos giorra ná na cinn Gentoo.De gnáth, caithfidh tú /etc/resolv.conf a chur in eagar, agus deimhnigh ní athróidh rud ar bith é. Ach tá muid ábalta an stuif sin a fhágáil ar lar mar bheidh muid ag suiteáil pdnsd mar taisc DNS. Nuair a shuiteálann Debian pdnsd, déanann sé an stuif eile sin.

These instructions are a lot shorter than the ones for Gentoo users. Normally you would have to edit /etc/resolv.conf, and make sure that nothing will overwrite your changes. However, we can skip all that because if you're using OpenDNS, you'll probably want a local DNS cache so your computer doesn't have to go back to OpenDNS for subsequent queries. I used pdnsd. When Debian installs pdnsd, it does that other stuff for us.

1. Suiteáil pdnsd.

1. Install pdnsd.

aptitude install pdnsd

Roghnaigh "manual" mar "pdnsd configuration method".

When asked to select the pdnsd configuration method, choose "manual".

2. Cumraigh pdnsd.

2. Configure pdnsd.

Cuir an roinn "server" in eagair mar an sampla seo a leanas. Scrios an /* roimhe sin agus an */ ina dhiaidh sin.

Edit the "server" section in /etc/pdnsd.conf, following the example below. Be sure to uncomment it by removing the /* before and the */ after it.

server {
label = "root-servers";
ip =
timeout = 5;
uptest = query;
interval = 30m;      // Test every half hour.
ping_timeout = 300;  // 30 seconds.
purge_cache = off;
exclude = .localdomain;
policy = included;
preset = off;

3. Tosaigh pdnsd.

3. Start pdnsd.

/etc/init.d/pdnsd start

Má bhfaigheann tú teachtaireacht mar "Could not bind tcp socket: Address already in use", b'fheidir go bhfuil named ag rith. Stop é le killall named.

If you get messages such as "Could not bind tcp socket: Address already in use", you might have named running. Stop it with killall named.

4. Deimhnigh go feidhmíonn sé le ceist úr.

4. Verify that it works for fresh queries.

dig www.opendns.com

Seo toradh ceart:

The result should look like this:

; <<>> DiG 9.4.2-P2 <<>> www.opendns.com
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 7419 
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0  

;www.opendns.com.               IN      A  

www.opendns.com.        30      IN      A  

;; Query time: 927 msec 
;; SERVER: <-- OpenDNS server
;; WHEN: Sat Nov 15 18:46:44 2008 
;; MSG SIZE  rcvd: 49  

5. Deimhnigh go úsáidtear sonraí thaiscthe le hathceist.

5. Verify that it uses cached data for repeated queries.

Eisigh an ceist céanna dig (dig www.opendns.com) faoi dhó, agus breathnaigh ar an líne ;; Query time:. An darna uair ba cheart do beagnach ar an toirt mar tá an eolas sa taisc cheana féin.

Run the same dig query (dig www.opendns.com) again, and look for the ;; Query time: line. The second time it should be nearly instantaneous because the information is already in the cache.
