View Full Version : How DO I? Setup RDNS
zmenchhofer
03-22-2005, 12:18
To set up RDNS you need to have your IP’s Delegated to you from FDC then you need to add it to named.conf and you will need to also create a new PTR for each IP range
Lets say you have a Class C address and you have 66.90.111.50-75 you will need to add a line like this to named.conf
zone "111.90.66.in-addr.arpa" IN {
type master;
file "/var/named/66.90.111.db";
allow-update { none; };
};
Then you will need to create a new zone file something like this
$TTL 86400
@ IN SOA ns1.yourhost.com. yourcontact.emailaddress.com. (
2005021601 ; serial
28800 ; refresh
14400 ; retry
3600000 ; expire
86400 ; ttl
)
IN NS ns.yourhost.com.
50 IN PTR WhatEverYouWant.Com.
51 IN PTR WhatEverYouWant.Com.
52 IN PTR WhatEverYouWant.Com.
53 IN PTR WhatEverYouWant.Com.
54 IN PTR WhatEverYouWant.Com.
55 IN PTR WhatEverYouWant.Com.
And so on…..
Any questions just ask!

Sticky :)
thank you for taking the time out to write this! ill be sure to use it when i play around with it.
thanks again.
Does this means that if you do this, when you go to IRC, your host will be listed as the one you specified such as 50 IN PTR WhatEverYouWant.Com? Kinda reverse dns spoofing huh?

You can only apply Rdns for the ips u own, and yes, u can make it resolve whatever u want
And how bout IPv6 RDnS ? can someone shed some light on that ?

Thx zmenchhofer.
If I have the domains' dns managed at dnsmadeeasy, should the reverse dns be done at the server or at dnsmadeeasy?
zmenchhofer
09-08-2005, 14:48
depends where you have the ips delegated to
allanite
09-08-2005, 16:23
if I have ips delegated,
do I do the reverse dns on my server here at FDC or
I do the reverse dns at dnsmadeeasy the service I use for my dns management for alll my domains but
my server is running dns and bind?
Thx
you have to do it in your server. ( here in FDC )

You also have to have FDC delegate reverseDNS Authority to you as normally you have to request them to do it. But they will transfer that power directly to your server if you ask.

yep thats one reason why I <3 FDC, I can change my rdns on the fly! wooty woo!!!!!!

can i set the reverses using WHM tools or just editing files on ssh?
WHM NO
and editing files NO
u must have ur IP delegated from FDC and then u creathe the zone file. like is in the first post. when u have it, you can do it, just like the tuto says.
rafaelgp
08-12-2006, 00:56
yeah, ok. but whats the best thing to do... ask for FDC to setup the reverses or ask them for delegate the IPs for my server?
ask one of both, u can ask to make the reverse u want, or u can ask for delegated ips
rafaelgp

i have to do something special to set an A ENTRY for my ips with reverse?
i setup a hostname and it is not resolving...
example:
$ host 123.123.123.123
123.123.123.123.in-addr.arpa domain name pointer srv1.domain.com
$ host srv1.domain.com
Host srv1.domain.com not found: 3(NXDOMAIN)
why its happenin?
create a A zone for srv1.domain.com in ur control panel

chandro: before doing it i tryed another thing...
instead of putting SRV1.DOMAIN.COM in the form at WHM, i just put SRV1 and it started working... I dunno why, but it started working.
hehe
thank you for ur attention.
rafaelgp
08-24-2006, 01:04
haha
I'm quite dumb, lol... I dunno why, but in this case I used "srv1.domain.com" instead of "srv1", for example... That's why it wasn't working... I think I was sleepy and put it very fast just to not forget doing, hehehe.
Take it easy chandro, good week. C ya.

How can I creat the Zone file?
HAVE U ur ips delegated from FDC ???
if not, u are losting time, cant modify that.
if yes, read the 1st post of this thread
mmm having a little problem :p
zone x.90.66.in-addr.arpa/IN: has no NS records

Im having troulbe understanding 2 things
$TTL 86400
@ IN SOA ns1.yourhost.com. yourcontact.emailaddress.com.
Ok is that myname@mydomain.com or myname.mydomain.com?
IN NS ns.yourhost.com.
50 IN PTR WhatEverYouWant.Com.
51 IN PTR WhatEverYouWant.Com.
52 IN PTR WhatEverYouWant.Com.
53 IN PTR WhatEverYouWant.Com.
54 IN PTR WhatEverYouWant.Com.
55 IN PTR WhatEverYouWant.Com.
]
Ok so is that ns.mydomain.com or
ns1.mydomain.com
Thank you very much :)

No matter ns. or ns1. its just your nameserver. Put your nameserver.
Also you can use cpanel/WHM DNS edit function.
thenks for your reply
Well I did all that and,
All that happend as a result is named skyrocketed cpu and mem usage HAHA :D
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
6731 named 20 0 53436 17m 1964 S 1.3 2.4 0:36.26 named
Dnsstuff.com said broken nameserver cant get result
Server ns1.xxx.xxx is reporting a server failure (it is probably broken).
If anyone has the time to help thanks if not its no biggy Im not a client at fdc now just a community member :P
its ok,
I worked it out all by myself!
I still dont understand how to add bluk like you have explained but I add each ip via directadmin and it works
When I tried doing a bulk database file it wouldnt work!
what do I do if I had FDC add my reverse PTRs in their servers?
I have forward zone ok, is there anything special I need to do for reverse (like resolv.conf, hosts or anything else) as they are doing reverse?
no, you just create zones with the hostnames, FDC do the reversers, dont have to change anything on resolv.conf
NOTHING!
If you're looking for IPv6 reverse DNS check this link out -> http://www.fpsn.net/?pg=tools&tool=ipv6-inaddr
Hmm....
I'm having some troubles. I've done it a dozen times before, but never ran into this problem;
Jul 14 22:03:42 gecko named[31118]: loading configuration from '/etc/bind/named.conf'
Jul 14 22:03:42 gecko named[31118]: zone 15.159.67.in-addr.arpa/IN: has no NS records
Anyone have some suggestions?

Assuming you already have an NS line, you simply have to add a space before the "IN" word at the NS line:
needs_space_here IN NS ns1.yourdomain.com.

Haha, that's such an easy fix, shame I just sent them my PTR entries 3 minutes ago. :/ Oh well, 3 months down the road I'll need to change them all again ;)
Thanks for the help psyxakias

I want to set rDNS. My current rDNS point to a wrong hostname (maybe previous owner of the IP) giaitri4vn.info
[root@server18 ~]# nslookup server18.hosthat.com
Server: 66.90.68.15
Address: 66.90.68.15#53
Non-authoritative answer:
Name: server18.hosthat.com
Address: 208.53.170.247
[root@server18 ~]# nslookup 208.53.170.247
Server: 66.90.68.15
Address: 66.90.68.15#53
Non-authoritative answer:
247.170.53.208.in-addr.arpa name = giaitri4vn.info.
Authoritative answers can be found from:
170.53.208.in-addr.arpa nameserver = NS3.FDCSERVERS.NET.
170.53.208.in-addr.arpa nameserver = NS4.FDCSERVERS.NET.
NS3.FDCSERVERS.NET internet address = 66.90.66.137
NS4.FDCSERVERS.NET internet address = 66.90.66.138
[root@server18 ~]#
I need rDNS changed to server18.hosthat.com
On asking FDC support, they told me
For reverse authority over your IPs, please provide the following:
Put your ips in the following format:
subnet: 66.90.68
69 IN NS ns2.blah.com. <--- put dot
70 IN NS ns2.blah.com. <--- put dot
OR you can supply us with the PTR entires.
Please do so in this format:
Subnet 66.90.112
4 IN PTR blah.domain.com. <--- put dot
5 IN PTR another.domain.com. <--- put dot
Thank you,
Can anyone tell what i have to do ?
I need the rDNS of IP 208.53.170.247 set to server18.hosthat.com
Thanks,
Yujin

Subnet 208.53.107
247 IN PTR server18.hosthat.com.
Unless you want to configure the PTRs within your own nameserver, and then you can do so using the first method (better if you plan to make changes in the future).

Thanks for the reply.
Subnet 208.53.107
How you get this ? First 3 digit of my IP ?
My IP is 208.53.170.247, so subnet is 208.53.170 (you posted 208.53.107, that is mis type ?)

They should make it easy, for example, If you open a ticket saying,
Please set rDNS
12.182.190.19 > server1.yourdomain.extn
They should just set that. Most datacenter will do that. With FDC you need to do it in complex way. Some data center allow you to do it in their control panel.

like who ?
If unsure how to do your own DNS PTR entries on your own server this is how FDC Likes it done in ticket for PTR's.
subnet 123.123.123
25 IN PTR some.domain.com.
26 IN PTR some.other.domain.com.
27 IN PTR some2.domain.com.
28 IN PTR some2.other.domain.com.
And if you're wanting to have NS entries done... it assume's you are doing 2 nameservers.
Try the following:
subnet 123.123.123
25 IN NS n1.yourdomain.com.
25 IN NS n2.yourdomain.com.
26 IN NS n1.yourdomain.com.
26 IN NS n2.yourdomain.com.
27 IN NS n1.yourdomain.com.
27 IN NS n2.yourdomain.com.
28 IN NS n1.yourdomain.com.
28 IN NS n2.yourdomain.com.
And another Example for IPv6 -- this requires you to have NS entries for your ipv6.
$ORIGIN 7.a.4.0.1.1.2.1.0.3.4.0.1.0.0.2.ip6.arpa.
$TTL 3d ;
