i use centos based server. yesterday everything was OK. but now, when i connect via SSH, my server can't resolve hosts. wget, ping, or curl don't work. also i use VNC to remote desktop. when try to open a page via firefox, it says server not found.
View 1 RepliesMy VPS was a clean build 2 weeks ago and so far i have installed cpanel and configured everything and added accounts. I began that one of my scripts that uses gethostbyaddr($ip) was failing to resolve any of the ip's it received. I made another PHP file to test this, with this code:
PHP Code:
<?phpecho file_get_contents[url];?>
Resulting in:
Warning: file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: Name or service not known
The thing is, the VPS is resolving domains just fine
I can ping, send emails, even dig:

I have no clue what's up, and i think there must be a guru here that has an idea of what is going on?
my server seems to have lost its ability to do name lookups:
Quote:
[root@cp ~]# wget =>`ossec-hids-2.0.tar.gz'
Resolving failed: Temporary failure in name resolution.
it hangs on the "Resolving bit for a long time.
my resolv.conf file is as follows:
Quote:
nameserver 66.90.68.16
nameserver 66.90.68.26
which are the 2 nameservers of my datacenter.
I tried doing a /scripts/upcp --force and I get this:
Quote:
[root@cp ~]# /scripts/upcp --force
Updating /scripts...
Sync Source:
and it just hangs there
the sites I am hosting use PHP script that make a lot of outbound web connections so this is crippling my server
5 hours back I got fails of services mails and then I restart VPS but after few minuts services status up but sites not working.
I contact with support and they told me "Service Named is down on your server".
Any how they update Cpanel, during updation I got email that with subject
Quote:
[ipcheck] Problems with dns setup on server.servername.com
The hostname (server.servername.com) resolves to . It should resolve to xx.xx.xxx.xxx.
Support added entries for me, but sites still not up. They again updating CPANEL. Seems they unable to solve problem.
I got a new server from uk2, has whm but i just couldnt get the server to work, i changed hostname and made nameservers etc but couldnt get it to work i pointed ips to hostnames and everything no response, domain is www.uploadline.com ns1.uploadline.com and ns2.uploadline.com i havent used cpanel for 2 years now and i used to have alot of experience in it before these days i just stick to directadmin and other control panels.
I just need to ask a few questions and i need help too to get my server up and running as im losing alot of time and money here
i remembered when i changed hostname on whm i need to run this through ssh:
/usr/local/cpanel/cpkeyclt
So i did, and this was the result:

i am having a problem getting a dedicated server running for Unreal Tournament GOTY. everytime i create a dedicated server i get this error in the console:

im running through a router.
I have a fresh server running CentOS 6 (final). I am trying to install Plesk 11.5.30 but i am experiencing some problems. When i run the plesk-installer i get this message:
Your host name must resolve to the correct IP address of your server, unless you are using network address translation (NAT).
Please quit Parallels Installer, fix the host name resolution problem, and then try installing again.
You can skip the hostname check and continue the installation, however, in such a case, the installer cannot guarantee successful installation.
Now, in my /etc/hosts file i have this:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
Is this correct? Or do i need to add/change something else?
My server is in the clound.

Has anyone experienced a similar problem? I have gone over the DNS records countless times and see no problems. The site is hosted on my own dedicated server.
I was in the market for a new dedicated server after a couple of years with my previous provider. The previous provider did nothing wrong but they were no longer competitive when it came to CPU and memory.
I moved first to geekrack. And I left them after a week and a half as they never were able to get my rDNS records setup.
I found Universal Hosts on this forum and gave them a shot. I had asked for an operating system that they didn't offer normally (Debian 64 bit) and they said that they could do it. However, when my server was setup it was 32 bit Debian instead. They apologized and had Debian 64 bit setup less than 24 hours later.
When I asked them to get rDNS records setup it took a few hours but they were setup correctly and they worked.
Universal Hosts is also a BurstNet reseller but compared to my other attempt at using a BurstNet reseller they are fantastic. While the initial config was incorrect they worked quickly to fix it and were very professional about it.
So after two weeks - so far so good. Keep up the good work UniHosts!
I am running Apache2.2, PHP5.I have been running with virtual hosts on a Windows 7 environment fine for a couple of years successfully, but have just had to move to a Windows 8 environment.It looks like Apache and PHP have installed and are working fine, but my Virtual hosts are now not being recognised. From what I can tell, it is the Windows 8 hosts file that is having a problem, as it looks as though it is now just setup to Block websites.
If I make the host file just have the one line127.0.0.1 localhost entry, then the very first Virtual Host from my apache config file will come up, but the rest are not found.If I put the usual 127.0.0.1 mywebsite.name aliasname is appears as though my website works momentarily and then is blocked..
What is the best, stable and free dns resolver ips for shared hosting servers?
View 4 Replies View RelatedI am new to the dedicated servers. I have just upgraded myself to a dedicated machine.
I am getting error "couldnt resolve host" at every domain name when I type like
wget http://google.com
wget http://yahoo.com
I searched over internet and found some people telling that I should put nameserver to /etc/resolv.conf?
nameserver <ip here>

I dont know what IP to put here or if it is a solution to my problem.
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: 208.53.183.125. 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 208.53.183.125. 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: 208.53.183.125
-Primary/secondary nameserver
Primary Nameserver: ns1.mydomainname.com (A entry = 208.53.181.26)
Secondary Nameserver: ns2.mydomainname.com (A entry = 208.53.181.27)
-Resolver Configuration
Primary Resolver: 66.90.68.25
Secondary Resolver: 66.90.68.26
-Additional IP my webhost gave me to use:
208.53.181.26 (used in primary name server)
208.53.181.27 (used in secondary name server)
208.53.181.28
-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 = 208.53.181.26)
ns2.mydomainname.com (A entry = 208.53.181.27)
2) My edit "edit /etc/resolv.conf" contains the following:
Search localdomain
nameserver 66.90.68.25
nameserver 66.90.68.26
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: 208.53.183.125.
I've been having this problem for a while now. I have a dedicated linix server running with the cpanel. I've setup my own nameservers and for the most part it all runs without a problem. However, every now and then the domains will not resolve for many people.
This may only last a few minutes but it happens regularly. There doesn't seem to be any pattern. The server is still available via IP address. Also, any domain name set as a nameserver with the registrar is not affected by this problem. All other domains are affected. This problem has persisted over many cpanel updates.
I have gone through all the nameserver files (I can think of or have read about) looking for something that may be causing this but everything looks normal.
I have nameservers setup on my server. As I have changed my servers, I need to resolve the sites. I changed the nameservers Ips to resolve to new one:
67.159.33.250 and 67.159.33.251
But my sites and my clients sites are going down.
[url]
And similar report by dnsreport is being given saying that NS didnt responded timely.
I have installed WHM 11 on centos 5.3.
Currently I get problems that domains at certain places not open.
Like e.g I write my server IP XXX.XXX.XXX.XXX it works fine and I get ping reply also, but at the same time I write [url]it would not resolve.
Similarly in web browser I write server IP it gives cpanel page but on same computer I write [url]I get page cannot be opened, when I refresh the page at certain times then it would open. Now once it is opened in the same computer it would work fine here.
In some internet connections it works fine i.e no problems, in some connections get similar problems that domains does not resolve properly.
I checked my named service works fine.
I've got several subdomains on the ethoshosting.com server, but I recently created a subdomain (the same way as before) and it doesn't resolve
The dig command run through shell works. DNS records seem to be setup. I restarted the DNS and even the http server.
What gives? (it was a WHM setup via whmcs)
how do i speed up dns resolving my website. It is taking much time about 5-8 seconds. My site is phpfavorites.com
usually when i type youtube.com and like other websites, those sites load much faster than anything. Is this dns or any other issue>
the DNS Server never resolves, i create one account on my server, i put the nameservers... about 6 Hours ago and nothing, i setup the Domain DNS and nothing, what can be? how i can fix this?
I have a Dedicated Server (Xeon 2.8 | 1 GB Ram)
OS: Fedora 6
I can't resolve hosted domains on ssh or via php on my server. All of other domains fine when i dig or ping but mine is not.
I did run fix scripts for dns and restarted named but result is still same.
Also, when i try to reach one of my domains via php's fsockopen function, i get "65 No route to host" or "68 Too many users" error.
Yesterday we registerd and created 2 domains in our server.
Everything is ok, files uploaded, dns zones created, httpd virtual host created...
The problem is that trying to browse the site trough http://www.site.com redirects me to [url] my main server IP address, this page shows a cPanel Welcome message.
But, using [url], the site is loaded ok, withouth any problems.

I set up a domain in plesk 8 (LAMP), but the www version of the domain doesn't resolve via the browser, wheras the non-www version does. I set the nameservers (and glue records) yesterday.
Why might this be? Could this be due to dns propagation?
on my server i have 104 accounts and the MySQL Usage for th cpus is 25.23
like this pic [url] is that danger? and how can i resolve it?
I have come accross an issue with DNS in cpanel 11.x , where named.conf is badly configured by cpanel ,
Here is how a DNS report from dnsstuff.com would look because of this :
FAILS for SOA record
Fails for lame nameservers .
Here's how to fix it ,
SSH to server ,
Backup your named.conf file by
cp /etc/named.conf named.conf.back
then
pico /etc/named.conf
Replace
Code:
include "/etc/rndc.key";
controls {
inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
};
options
{
/* make named use port 53 for the source of all queries, to allow
* firewalls to block all ports except 53:
*/
query-source port 53;
// Put files that named is allowed to write in the data/ directory:
directory "/var/named"; // the default
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";
};
logging
{
/* If you want to enable debugging, eg. using the 'rndc trace' command,
* named will try to write the 'named.run' file in the $directory (/var/named).
* By default, SELinux policy does not allow named to modify the /var/named directory,
* so put the default debug log file in data/ :
*/
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
// All BIND 9 zones are in a "view", which allow different zones to be served
// to different types of client addresses, and for options to be set for groups

//
// By default, if named.conf contains no "view" clauses, all zones are in the
// "default" view, which matches all clients.
//
// If named.conf contains any "view" clause, then all zones MUST be in a view;
// so it is recommended to start off using views to avoid having to restructure
// your configuration files in the future.
view "localhost_resolver"
{
/* This view sets up named to be a localhost resolver ( caching only nameserver ).
* If all you want is a caching-only nameserver, then you need only define this view:
*/
match-clients { localhost; };
match-destinations { localhost; };
recursion yes;
zone "." IN {
type hint;
file "/var/named/named.ca";
};
/* these are zones that contain definitions for all the localhost
* names and addresses, as recommended in RFC1912 - these names should
* ONLY be served to localhost clients:
*/
include "/var/named/named.rfc1912.zones";
};
view "internal"
{
/* This view will contain zones you want to serve only to "internal" clients
that connect via your directly attached LAN interfaces - "localnets" .
*/
match-clients { localnets; };
match-destinations { localnets; };
recursion yes;
zone "." IN {
type hint;
file "/var/named/named.ca";
};
// include "/var/named/named.rfc1912.zones";
// you should not serve your rfc1912 names to non-localhost clients.
// These are your "authoritative" internal zones, and would probably
// also be included in the "localhost_resolver" view above :
};
view "external"
{
/* This view will contain zones you want to serve only to "external" clients
* that have addresses that are not on your directly attached LAN interface subnets:
*/
match-clients { !localnets; !localhost; };
match-destinations { !localnets; !localhost; };
recursion no;
// you'd probably want to deny recursion to external clients, so you don't
// end up providing free DNS service to all takers
// all views must contain the root hints zone:
zone "." IN {
type hint;
file "/var/named/named.ca";
};
// These are your "authoritative" external zones, and would probably
// contain entries for just your web and mail servers:
// BEGIN external zone entries
With
Code:
include "/etc/rndc.key";
controls {
inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
};
And then goto bottom of the file and remove
}; at the bottom .
Save file and exit
then test config
service named configtest
if you have done this correctly , it should display something like this:
zone blue.xxx.com/IN: loaded serial 2007070901
zone xxx.com/IN: loaded serial 2007070906
zone ns1.xxx.com/IN: loaded serial 2007070901
zone server.xxx.com/IN: loaded serial 2007071001
zone xxx.net/IN: loaded serial 2007071001
Then restart named by
service named restart
your DNS should be working now .

View 7 Replies View RelatedI contacted burst.net support and 15 minutes later I had my old server.
Brian, Shawn for Burst - Thank you and just FYI, you have made my day!
Recently I stumbled along a host on here with a good rep and that uses direct admin.
Because they were very nice on the live support I signed up to see what direct admin was like.
Its very diferent from cpanel. Some parts seem to be harder to use like the phpmyadmin requires the username and password to the database you created not the control panel username and password like cpanel. Although I guess that could be a good security feature just in case some one gets into the control panel they can not get into the phpmyadmin, then again if they are smart and were able to get into the control panel they could get into ftp and look what the username and password is on the config file for the script you are using.
The bandwidth meter seems to be better in direct admin although I think its acting up for me as its putting yesterdays bandwidth on todays. I was told by the host that it updates every 2 hours and at first it did but now its gone to every day. Oh and unlike cpanel this bandwidth meter includes bandwith used by the control panel.
Niether one from what I can tell counts sftp though at least for the hosts I have right now.
The error message is

Every web hosting company I've seen has a certain amount of monthly bandwidth for a dedicated server. For example, one hosting company offers a dedicated server with 10TB of bandwidth per month.
Question is, why don't web hosting companies offer 2 monthly bandwidth options like International and Local? Local bandwidth costs alot less than International bandwidth.
So for example, a web host based in the USA should have a Dedicated server with 10TB Local monthly bandwidth and 10TB International monthly bandwidth.
Can't hosting companies detect where the dedicated server is being accessed from?
Does anyone have any recommendations for a dedicated server host? I'm looking for a dedicated server with a Xeon Harpertown quad core with a 15K SA-SCSI hard drive.
