To complete the other answers, there is no authoritative database of complete IP -> name mappings.
DNS provides for two kinds of mappings:
name -> IP. Multiple names can map to a single IP
IP -> name (aka "reverse"). A given IP can map only to a single name.
Whether there is actually a reverse (IP -> name) mapping and what it points to is subject to the ...
The questioner is asking to know why he can't use one IP address for two nameservers, but in fact he can use the same IP for both. This is often done for servers with only one IP address available to it.
Having a second IP address on the same server is of little benefit, since if that server goes down, both IP addresses will be unreachable. The only ...
Don't know if it's possible with simple command, but there are special "Reverse-IP" services just for that, check that one for example: http://viewdns.info/reverseip/
Apparently if you share IP with other domain, that is considered... malicious, like it's sending spam or spreading some viruses or having some "illegal" content, then your good domain also ...
In a Google Webmaster Help thread, Google's John Mueller said in response to the question of SEO and server location:
For search, specifically for geotargeting, the server's location plays
a very small role, in many cases it's irrelevant. If you use a ccTLD
or a gTLD together with Webmaster Tools, then we'll mainly use the
geotargeting from there, ...
You have to be running Apache or another webserver on your VPS. Also you will need a DNS host for pointing the domain to the hosting, i recommend Cloudflare.com . You will also probably want MySQL and PHP installed.
Alternatively you can create your own DNS server with bind using this tutorial:
In 000-default (usually in /etc/apache2/sites-enabled/000-default)
You can use the VirtualHost tag to separate different sites.
To answer your question directly: No, in most cases there is no negative impact for sharing an IP with a bad domain. How do I know this? I am the SEO oracle. I come from the future to save humanity.
Kidding, but only sort-of. If there was such a thing as IP penalization, we would be seeing far far different search results than what we do today because many ...
I'll give my thoughts on VPS, as I have no experience in cloud.
I chose to get a cheap VPS(I pay $40/mo) and moved ...
It could be done with a single SSL certificate. Specifically, what you want to do is to provide 'Subject Alt Names' in the certificate.
Take a look at Google's certificate for example, which has the following Subject Alt Names. In other words, they have one certificate for all of those domains.
DNS Name: *.google.com
DNS Name: *.android.com
It sounds like your domain records have not propagated yet. This means that the domain name servers around the world that store a record of your domain information haven't updated with the latest details, so they are still 'sending' visitors to your old server.
The solution is to wait. It can take between 0 and 48 hours for domain name changes to update ...
To keep your website up and running you should have multiple name servers. You are required to provide two, but three or four are recommended. Putting in the same IP address for both means that if that server goes down, your website goes down as well. For best results, the name servers you use should be distributed around the globe and run by a reputable ...
Linking PHP as an Apache HTTPD module makes them inseparable.
This is not without problems:
Indeed, many PHP libraries aren't threadsafe, so it's essential to use the prefork-mpm module for HTTPD 2.x in production to implements a non-threaded, pre-forking web server that handles requests in a manner similar to HTTPD 1.3.
But this approach strongly affects ...
One IP could be for your web (HTTP/HTTPS) traffic, another could be for FTP or SSH access, another could be for mail, &c. If the publicly known IP (i.e. the one published to DNS) is separate to the one used for administration (only known by you and your team) then that would be a way of securing your server - by allowing different types of traffic over ...
Check for error logs. I had a Wordpress site that was constantly running out of disk space and it turned out to be a large error log. If this is the issue the first thing you do is fix the issue that is being logged as not doing so will result in this problem never going away.
Virtual Private Server or Cloud Server model suits small or medium businesses that are looking to optimize their IT infrastructure yet don’t want to incur the higher costs of fully dedicated server hosting. VPS is just like owning a set amount of space in an office building. Virtual private servers provide the performance of a dedicated server running ...
You could use a service that does "reverse IP lookup" to check for websites hosted on the same server / the same IP address. This service http://viewdns.info for example lets you simply enter a domain name into "reverse IP lookup" and spits out a list of other websites / domains hosted on the same address. The same here: http://www.yougetsignal.com/tools/web-...
You may want to look at the info provided here :
(Essential content inserted here as that link is down in Feb 2013.)
Look for the section in server.xml like this and change the port to 80.
<connector port="8080" protocol="HTTP/1.1"
You could use a stress-tester like this one: http://loadimpact.com/ which has a free option, but limits it to 50 users. Paid-for (or registered users) can get increased stress levels.
I like this service specifically because it generates very useful graphs, and a detailed report containing page load errors, etc.
There are many other services like this one, ...
Containers running on virtualised servers such as OpenVZ or Virtuosso have a shared kernel (and shared memory) with every VPS on that machine. This means that the container time will be the same as the host computer's time, and the only person who can control that is the server administrator.
You should still be able to edit the timezone of the VPS, though, ...
I’ve checked it again, should work out of the box.
In case it doesn’t:
Try this thread: http://wordpress.org/support/topic/users-not-receiving-activation-email
Try reinstalling Exim4 – “bash setup-debian.sh exim4”
Try installing Postfix instead Exim.
There is also a new version of lowendscript made by Xeoncross - https://github.com/Xeoncross/...
What happens when you run your domain through intodns.com? That can help you spot errors in your setup.
A common mistake is including or not including a dot on the left hand side of the entries in zone setup.
Consider this entry with a dot
This creates a record "testing" pointing to the specified IP address. Probably not not what you want.
Yes, and you don't need a plugin. Just log into Plesk and go to:
Server Management -> Tools & Settings -> Server Information (under the "Server Management" column)
It breaks down the following:
Physical Memory Usuage
Virtual Memory Usage
Hard Disk Usage
You might also find "Server Health" helpful too, because it breaks down a lot of ...
Normally VPS can be oversold by the provider. It is difficult to do such in Xen VPS. Otherwise go for VPS with a good provider or try XEN VPS with any provider.
Cheap provider oversell it [even if they market the resources as "yours"].
Typically, the only way you know if a system will handle certain loads is by testing or trial by fire -- that is just seeing if it survive a real load spike.
In terms of a VPS, there is no guarantee that a VPS would handle the load any better than your shared hosting account.
All servers have limits and if your traffic hits that limit, it may fail or ...
There is no way at this point to do that with Linode. Having used them a while back as a provider I believe they sent emails at the time to alert when usage approached 100% of the plan allowance so you could make the appropriate changes to reduce your costings but there is no way in advance to prevent the usage from going over without actually monitoring it.
Here's the setup you want:
An 'A Record' pointing to your VPS server IP. In this case, example.com. Or: "A Record | @ | VPS IP address"
A Cname record stating the subdomain (www) is the same as the root version (@). Or: "Cname Record | @ | www.example.com". This means when someone looks up 'www.example.com' it redirects them to the A record for 'example....
