Our internal DNS queries go through ActiveDirectory. We are hosting a site that is not in our domain, but internal users need to get the internal IP address for routing.
How do I configure ActiveDirectory to return A records for a few arbitrary domain names, not just those in our own domain?
I have an existing site that I would like to add a staging subdomain to. I created a new web site for it in IIS, added a host header for subdomain.mysite.com but when I try to get to the subdomain it is not found.
Do I need to create an A Record in my DNS to point subdomain.mysite.com to the server's IP or will the existing entry for mysite.com work? If not, can anyone see what I am doing wrong here?
My website takes awfully long time after entering the domain name and before the content starts showing up.
I assume this is something to do with the dns resolution or the networks.
How do I go about troubleshooting this problem? Where do I start and what tools do I need? I know I’ll need nslookup and traceroute. What else will I need?
There's a rumour that public domain name resolvers, like Google Public DNS, are still supposed to work with GeoDNS, because there's some field in the requests that lets them specify for which IP address they are doing a resolution, thus the authoritative servers can give a given resolver different resolutions for different final clients.
What's this whole thing called as far as RFCs go, and how does one mimic such resolutions, for testing purposes, e.g. with dig(1)? Else, what other tool is available to accomplish said task?
Today, I am suddenly getting the untrusted website error for all Google websites, but not for any other. Internet Explorer gives no such error. Reboot of this Windows 7 computer does not help.
Is this some kind of virus infection that is hijacking DNS resolution away from Google to some spoofer?
How can I resolve this issue and get Google websites working again normally?
If I manually enter a Google IP Address, the page loads correctly.
Apache 2.2
CentOS
Plesk 9.x
I am using Plesk to manage my domain names on my virtual host.and GoDaddy for DNS
I have created a new sub-domain blog.
I can see the httpd.include for example has a new virtualhost entry for blog.example.com
I can also see folders have been created for the subdomain blog vhost\example.com folder
But when I try to go to blog.example.com - I get an error - basically the host is not getting resolved
My site - example.com is working fine otherwise
Any idea what could I be missing ?
I did try restarting the apache web server as well
A newbie question regarding dns records
Let's say I've configured,
abc.example.com - A 10.x.x.x
and a CNAME for xyz.example.com
CNAME for xyz.example.com - abc.example.com
when a user does an http request for xyz.example.com what happens when the request reach the 10.x.x.x server. Will the URL be abc.example.com or xyz.example.com? (trying to find out if virtual host in apache need to be updated)
Thanks much
My main domain is example.com, but also bought example.org and example.net. I've configured my webservers at *.example.com to handle requests from the other domains and redirect them correctly to example.com, but I'd rather not re-configure all my DNS records at example.org and example.net to be the same as example.com.
Other than writing some ugly synchronization script, what should I do to have route53 answer queries against my "other" domains with the same data from the "main" domain?
Since my server is under a sustain DNS amplification attack (DDOS),
I configured fail2ban and initially my outgoing traffic dropped markedly.
Anyway, after a few hours (mostly +10), fail2ban uses about 75% ram and seems to be crashed in some way, because the outgoing traffic raises imediatly after. When I searched the web for the memory problem, I found some people complaining about high fail2ban memory usages as well. But the recommended solution, to insert an ulimit command into a fail2ban config file, did not change that much for me.
Can I configure my domain, example.com's name servers as:
ns1.dyndns.com
ns2.dyndns.com
ns1.opendns.com
ns2.opendns.com
That is, combining free dns services to create a redundant name server array? Note these name servers from different companies are not aware other companies' name servers also serve our domain.
In case one company, say, ns1(2).dyndns.com is down, will people experience interruption when visiting my example.com? If one name server is unreachable, the next name server will be tried, or?
I have a self hosted server with Apache2 pointed with the domain example.com. I have also some virtual servers www.example.com, cloud.examle.com, etc.
This server is in my LAN, and when I try to acces to my server within the lan throw www.examle.com y get my router's configuration page. From outside the LAN www.example.com and cloud.examle.com works properly. From inside the LAN 192.168.1.33 (server internal IP) shows the default webpage (www.examle.com), but I can not get cloud.examle.com
I also have a LAN name server in 192.168.1.33 with bind9.
I set up my gateway 192.168.1.1 with my LAN-NS as primary NS
I solve this problem creating a new dns zone in the NS.
This are my config files:
;ZONE-1
$ORIGIN .
$TTL 86400 ; 1 day
home.lan. IN SOA server.home.lan. hostmaster.home.lan. (
2008080901 ; serial
8H ; refresh
4H ; retry
4W ; expire
1D ; minimum
)
home.lan. IN NS server.home.lan.
$ORIGIN home.lan.
; Set the address for localhost.home.lan
localhost IN A 127.0.0.1
router IN A 192.168.1.1
server IN A 192.168.1.33
mypc IN A 192.168.1.132
;ZONE-2
$ORIGIN .
$TTL 86400 ; 1 day
example.com. IN SOA www.example.com hostmaster.home.lan. (
2008080902 ; serial
8H ; refresh
4H ; retry
4W ; expire
1D ; minimum
)
example.com. IN NS 192.168.1.33
$ORIGIN examle.com.
localhost IN A 127.0.0.1
www IN A 192.168.1.33
cloud IN A 192.168.1.33
My DNS and my names are working properly now
My question are:
What do you think about my solution?
Can I change the A zone with CNAME to server.home.lan (this is the domain in the LAN to the server)?
How can I set a default IP for all my whatever.example.com?
I host my site at domain.com.
My DNS entries in Route53 are as follows:
domain.com A xxx.xxx.xxx.xxx 300
domain.com NS stuff.awsdns-47.org 172800
domain.com SOA stuff.awsdns-47.org 900
I would like to redirect traffic from www.domain.com to domain.com, as currently this just returns a 404. This question on SO suggested a PTR record, and I added that:
www.domain.com PTR domain.com 300
but it didn't work. What should I be doing?
Hello,
I have to manage two domains :
compagny.com
copagny.bigcompagny.com
I use Bind9 on Debian Lenny.
I want to use one Zone file for both domains.
If I ask for server.compagny.com, it will give me address 10.0.0.1
If I ask for server.compagny.bigcompagny.com, it will give me the same address 10.0.0.1
I don't want to create twice the same files for my DNS Server : Too hard to maintain.
How can I do that ?
Thx
I am running Exchange 2013 on Windows Server 2012 R2.
When I add my exchange account to Outlook, it seems to work perfectly (sending/receiving email, syncing everything), but when I open the account settings it has the following set as the Server:
[email protected]
I would have expects this to be: mail.domain.com since this is the DNS A record pointing to the IP of my server. Where is it getting this server name?
Hi,
I am wanting to setup a internal development server (LAMP), I need the web team to be able to access different developments sites ie:
example1.local
example2.local
example3.local etc
from within the network.
I believe it would be something to do with DNS?
Any help would be appriciated.
Kyle
What happens if you have 2 DNS entries:
Name | Type | Value
-------------+-------+--------------
example.com | A | 20.20.20.20
example.com | MX | mail.example.com
Does this mean that smtp requests to example.com will map to 20.20.20.20, and somehow request in the headers mail.example.com? What?
I'm in the process of migrating to a new server, but some traffic that should be going to old server is now coming to the new server before I am ready to migrate. My provider used an IP used as the secondary nameserver on the old server as the primary IP on the new server, so now my secondary nameserver is directing traffic to the new server.
Is there a way to forward the traffic hitting the new IP back to the old IP while I wait for DNS to propagate?
Server is Linux CENTOS 6.5 x86_64 w/ cPanel
Thanks
Please no spamming or aiming for cheap money.
The registrar needs to have a good ui, work with no downtime, be easy and flexible to use, support easy changing/adding of CNAME fields, MX records, and work well with outside host DNS.
Why pdnsd responds slowly/fails many requests to it even if it has found working upstream server?
I want pdnsd to just use the DNS server {it has probed,that is proven} to work and search for other configured variants only if that chosen server fails.
/* Most time only about 1-2 of configured servers does work, each time different ones. */
I'm running Office 2007 on Windows 7. When I ran the Microsoft Office 2010 beta installation, it asked if I wanted to upgrade the existing 2007 installation or install along side 2007. I later uninstalled 2010 and rebooted. When I re-ran the Office 2010 setup program, it no longer asked if I wanted to upgrade or install side by side. It just did a side by side install by default. How can I get it to re-prompt me, as I'd now like to upgrade my 2007 install.
Cross referencing figure and table captions is useful while editing a document but can become confude when copying and pasting between large documents.
I need to pass my document to a colleague who will collate my document with others and has requested that I remove or delete any cross referencing so that my "correct" cross references do not interfere or get interfered with by any other cross references that may be in my colleagues master collated document.
My document will be cut and pasted into the master and no further complicated instructions after that point will be tolerated by my colleague.
Is there a simple way to convert my cross references to simple text? I am using microsoft word 2013.
For the last two days, Outlook has decided it doesn't like URL's. Any email message that comes in containing an URL will show the following in an error dialogue message box when I click on the link:
General Failure. The URL was:
"http:/something.com/somewhere/". The parameter is incorrect
If I copy the link into a browser, it works correctly.
OS is Windows XP SP 3, Microsoft Office 2007 (Outlook), Internet Explorer 8 (also Chrome).
I have, of course, Googled this and the two most popular solutions are:
Solution 1:
Add/Remove programs
Set Program Access and Defaults
Custom tab
Make sure a default browser is selected
Solution 2:
Add/Remove Programs
Select the MS Office 2007 item
Click Change
Click Repair
I have tried both of these and I still get the problem.
Has anyone else had this problem and solved it with a solution other than those listed above?
I installed Microsoft Word 2010 using the handy web installation feature. The way this works is that Word installs a bare minimum of functionality and any time it needs a feature that has not been downloaded yet, it will download it in-place just as needed.
The thing is, this is stalling Word every few minutes. Every few minutes, Word takes a small nap while it tries to find some obscure feature somewhere. This is really annoying.
Is there a way to just tell the thing to completely download itself?
This was a nice functionality for the trial but it is extremely annoying in actual use.
