At one point I was able to access the hostname WITHOUT a alias entry in the DNS config. Then, I must have done something... because now I need an A record with purple pointing to the correct IP to get at it.
What did I do? Usually the hostname doesn't need to be entered in to BIND (or whatever DNS package)... is that right?
our company is ordering a new dedicated server and we are a little unsure what we should choose as far as the full hostname and nameservers of this one server.
This server will have a couple different websites on it, but really, there is only one BIG website on it... let's call it abcd.com.
While most would pick a hostname of host.abcd.com for instance, if at all possible, we would like the domain name part of the hostname to be something different than abcd.com. We own a domain name that doesn't point to anything yet (unuseddomain.com) and we were wondering if we could use that domain in our hostname.. host.unuseddomain.com.
And instead of using abcd.com as the domain name for our own nameservers (ie. ns1.abcd.com, ns2.abcd.com), we would like to again, use the unused domain name we own (unuseddomain.com) for the nameservers domain name: ns1.unuseddomain.com, ns2.unuseddomain.com.
Will this work? Is this perfectly acceptable?
Since the one website we really care about on this server (the one we got the server for in the first place) is abcd.com, is using the unuseddomain.com for the hostname and nameservers (as above) a bad choice in anyway regarding email deliverability? I understand that mail ISP's (hotmail, yahoo, etc.) do all kinds of checks on hostnames (PTR), etc... and we want to make sure that we aren't hurting ourselves in anyway by using an "empty" domain name that we own as our hostname's and nameserver's domain name.
For instance, if we send mail from the abcd.com account, it will use mail.abcd.com (220.127.116.11) as it's outgoing mail server... Hotmail will see this... do a reverse-dns lookup on 18.104.22.168 and see host.unuseddomain.com. See what I'm saying? It all will work, but will it toss up red flags?
Will the nameservers work if the nameservers are pointed to a parking page? For example:
I need to change my nameservers to ns1.mywebhost.com and ns2.mywebhost.com
(nameservers are made up)
These nameservers are from my web hosting service provider. When I visit the nameservers, it shows up a parking page from a domain parking service (let's say NameDrive parking page)
Will the nameservers function correctly and will my websites work? I have this question because usually the nameservers that I use, they always point to a CP page or something like that rather than a parking page.
I hope your day is going good. I've been trying to fix a problem I had all week. I receive daily email notification that "example.[url]" does not resolve to any IP. However, when in WHM, it already contains Server Main Ip: 22.214.171.124. I've tried a few solutions from the web, but to no avail:
IMPORTANT: Do not ignore this email. The hostname (example.mydomainname.com) resolves to . It should resolve to 126.96.36.199. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.
Some are all of these problems can be caused by /etc/resolv.conf being setup incorrectly. Please check this file if you believe everything else is correct.
You may be able to automaticly correct this problem by using the 'Add an A entry for your hostname' under 'Dns Functions' in your Web Host Manager
1) Within WHM, I have the following:
-Add an A entry for your hostname (I only have one listed) Hostname: example.mydomainname.com Server Main Ip: 188.8.131.52
-Primary/secondary nameserver Primary Nameserver: ns1.mydomainname.com (A entry = 184.108.40.206) Secondary Nameserver: ns2.mydomainname.com (A entry = 220.127.116.11)
-Additional IP my webhost gave me to use: 18.104.22.168 (used in primary name server) 22.214.171.124 (used in secondary name server) 126.96.36.199
-Current DNS Zone listing: example.com (my website URL that is currently working) example.mydomainname.com (hostname I made myself that contains the server main IP) ns1.mydomainname.com (A entry = 188.8.131.52) ns2.mydomainname.com (A entry = 184.108.40.206)
2) My edit "edit /etc/resolv.conf" contains the following: Search localdomain nameserver 220.127.116.11 nameserver 18.104.22.168
Issue: I receive daily email notification that "example.mydomainname.com" does not resolve to any IP. However, when in WHM, it already contains Server Main Ip: 22.214.171.124.
I have a server with RHEL 5 installed. The problem is that the server shows the output of the hostname command as (none). I checked the /etc/sysconfig/network file and it shows the correct hostname. I also tried to change the hostname in the /etc/sysconfig/network file and restart the server. But hostname command still shows (none).
I have a dedicated server with WHM 11.23.2. I am in the process of "attempting" to change the hostname for a group of websites and also the nameservers.
Let's say for practical senses that these were the old details: Hostname: abc.example.com Nameservers: ns1.example.com and ns2.example.com
I changed in the following sections of WHM..
Server Configuration -> Basic cPanel/WHM Setup -> Hostname to 123.newsite.com
Networking Setup -> Hostname to 123.newsite.com
Server Configuration -> Basic cPanel/WHM Setup -> Primary Nameserver to ns1.newsite.com and then...
Server Configuration -> Basic cPanel/WHM Setup -> Secondary Nameserver to ns2.newsite.com.
Networking Setup -> Nameserver IPs. I deleted the old ones and created the two new ones: ns1.newsite.com and ns2.newsite.com.
I have double checked that this information is still there. Obviously newsite.com is listed as a domain/account. However, example.com was naturally the first one associated with this server.
I performed a server reboot, apache reset etc.
This was three days ago. I assumed it had all changed over. Until I (stupidly) remembered that I hadn't changed the goDaddy information to point to these new nameservers. I panicked thinking all the sites (six of them) would be down. However, they weren't. When I tried to change the nameserver information for a domain in goDaddy it came back with errors... it would only accept ns1.example.com and ns2.example.com.
So, I did a tracert to the IP address of the server and indeed it comes back as abc.example.com. Every domain is associated with that static IP.
I can't even find anywhere where abc.example.com is listed within the WHM. All the new values are listed... so, where is it pulling this from? I thought the reset of the server (as a graceful reboot) would resolve this issue.. it hasn't. I've rebooted twice and awaited the thirty minutes for everything to get back online. No success.
The zone for the root domain splinteredmedia.net is missing, or could not be read. The ip address will be read from the webserver configuration and a new zone will be created for this subdomain. Bind reconfiguring on smpl using rndc Error reconfiguring bind on smpl: rndc: connect failed: 127.0.0.1#953: connection refused Created DNS entry for ns1.splinteredmedia.net
Is the error i get when i try to add a entry for one of my nameservers.
I have cPanel on a CentOS 5.1 VPS
I am still pretty new to CentOS
how would i go about adding a zone and if somebody cpuld point me to a place where i can read exactly what it is and how to set it up i would be very grateful
my VPS with Steadcom has been running for about six months now and for the most part I'm very pleased.
I'm not all that skilled at running it yet, still learning.
First, My email was being blocked by some recipients, I am using sendmail. So I had to change the hostname and the hosts file, and the network file to my domain name, instead of the hostname Steadcom gave me. This fixed the email and it seems receipients are okay with the new settings.
However, whenever I restart the VPS, these files and the hostname get reset. How can I make it so these are not changed... is this something I have to bring up with Steadcom or is it a setting I'm not getting quite right?
Second... my webmin seems to have problems. I can log in, but then sometimes I cannot navigate to the areas I need to, as I'll get a page not found error. I have been stopping and restarting webmin, and that sometimes helps, but sometimes not and I have to restart the whole server. Which I really don't want to do just for webmin. I don't really know webmin that well, either, so would love some help on what I can do about this.
Third.. when I have SSH running I often get Brute Force warnings for a bot or someone trying to log in. So I just stop the service all together. But when I restart, it starts up again. How can I keep SSH from starting unless I need it?
I've set up a few domains in WHM, though I noticed when I use Ping Plotter to do a traceroute on the domain, the result always shows host.mydomain.com as the last stop, instead of just mydomain.com:
Code: Target Name: mydomain.com " " 12 84 ms CWIE-LLC.car1.Chicago1.Level3.net [43.793.208.66] 13 82 ms [126.96.36.199] 14 84 ms host.mydomain.com [188.8.131.52] I was wondering, how can I configure the DNS in WHM so the last stop is just mydomain.com?
Say for example I have a cPanel dedicated server, with a hostname> earth.anonymous.com which is where I host several resold shared accounts all using my nameservers, ns2.anonymous.com and ns2.anonymous.com
I am using the cPanel dns, simply pointing the domain namesevers to two IP`s given in my IP allocation.
I wish to lease another server, using the hostname: venus.anonymous.com
This is where I start getting confused with the domain/dns. Would it be easier for me to use a third party dns service such as easydns to host the actual main domain dns?
If someone can understand what I`m getting at here, could they give me a few tips of getting this setup and easy and reliable as possible.
A lot of hosting companies are using anonymous hostnames, is this a good plan?
I have a VPS with the hostname myhost.domain.com, with four IP addresses, one of which is assigned to a shared hosting account (using WHM/cPanel) at sub.domain.com.
For email delivery purposes (I'm sending e-commerce receipts (that MUST be delivered) from PHP apps running on sub.domain.com), do I need to set up reverse DNS entries that say their IP addresses belong to myhost.domain.com, or to sub.domain.com?
i have a simple reseller account to give my clients some hosting space. one specific client keeps the domain registered with his current domain registrar. to point the domain name at his new hosting account (provided by me) he's saying that he just needs the "a-record", not the nameservers that i gave him originally. i can not seem to find an a-record for my hosting accounts anywhere ...
my hosting support is saying the client will just need the IP address. but afaik ip address is not == a-record
can anyone clarify what an a-record is exactly and whether or not it can be interchanged with an ip address?
this is for a .co.uk domain name and my reseller account is with hostgator
I would like to setup SPF record for my domain. I am using Google Apps for the domain.
But I will also be sending mail from my vps server. Hence what should I use?
v=spf1 a include:aspmx.googlemail.com ~all
v=spf1 a mx ~all
If both works, which one is better? I will be sending emails from subdomains of my main site too, so do I need to anything special for that?
I am using ~all instead of -all, because I sometimes send emails from my development server(which is having dynamic ip). Hence I don't want those emails to rejected, even if they are marked as spam.[url]
Here is my SPF record, but sending email I get this in the header
@ 86400 IN txt v=spf1 a mx ptr ~all
