How Do Websites Know IP Addresses

Apr 29, 2007

Does the client tell the site or a third party internet "authority" do so.

I've heard a guy that make a program that keep changing our IP. How can anyone do that?

I thought it requires a proxy to hide your IP. You can't just "lie" to a server right?

Dedicated IP Addresses; Multiple Websites With SSL..

Oct 30, 2008

Hello guys, I have been a longtime lurker (too long ) and I look forward to becoming an active member on the site...

I am still in the process of researching a reliable web hosting company. It has been a blessing and a curse to have so many choices. I plan to host multiple ecommerce websites (5) and will need SSL encryption. I have looked at Hostgator as a possible candidate, but their business package has just one dedicated IP address...

If I am running 5 seperate ecommerce websites, will I need 5 seperate dedicated IP addresses in order to utilize SSL for each individual site? My suspicion is yes due to security purposes...
Also what are good SSL certificates? RapidSSL appears to be a cheaper one, but is it the same as other certificate issuers? Or is buying certs equivalant to buying domains; just but the cheapest ones....

Thanks again guys... Just curious on what my options are. I'm "starting" out and testing the waters so to speak so a dedicated server or higher cost solution is out of the question yet. I would like to find a good quality shared server hosting plan with a reputable company who doesn't overloard servers for profit....

Any ideas what you guys would recommend with the above mentioned... ixwebhosting appears perfect for my needs due to the fact you get 8 dedicated IP's (so they say), but I have read nothing but bad things about them + the price is too good to be true...

When I hear the words "Unlimited" I want to run.. Unlimited and Cheap... LOL *rolls eyes* Want quality, fair price, for the above mentioned items...

How Do Websites Get Hacked?

Oct 20, 2008

Every now and then I'll run into a website that has a message that says it was hacked by a certain hacker. How exactly do this? Do they hack into the actual server or do they somehow get a hold of the website owners FTP info?

How Many Domains/websites On A VPS

Oct 17, 2009

I have a pretty 'beefy' VPS (Future Host 'Titanium' plan, 1Gb RAM, equal share, 750 Mb bandwidth, 50Gb disk).

I'm using it mostly to host relatively small, low-traffic Wordpress sites. Right now, there are about 40 domains & blogs set up.

The majority see only a few dozen visitors per day. A few have traffic around 100 visitors, and 1 or 2 may get up to 500 per day.

My question is, what might be a comfortable limit on domains/blogs I can host before I should start thinking about adding a 2nd VPS?

Can't Connect To Outside Websites

Jul 30, 2009

We can't resolve any outside websites, for example wget won't resolve any websites.

elvis:~# wget [url]

Resolving g-ecx.images-amazon.com... failed: Temporary failure in name resolution.
wget: unable to resolve host address `g-ecx.images-amazon.com'

How can we debug this? Its just started to do this, before it was fine for months.

We can resolve IP addresses fine.

How Can I Host My Own Websites

May 15, 2009

I have three domains that I want to host myself on my own computer. Two are temporary sites that I only put up on Memorial Day weekend for the Detroit Electronic Music Festival or Movement 09 to direct people to my after parties and the other site is a two page bio site for myself. I have a very tight budget this year and I can't afford to pay for web hosting all year round when these are only temporary sites even though I own the domain names all year round. I do know some of the promoters for the festival do the hosting themselves.

Like it'll be running ultra fast and suddenly, I can't get into ssh, whm, my websites or anything. When I ping it, no reponse. Is it because it restarted itself?

Cannot Access Websites

Jan 17, 2007

I think I broke my server. I was trying to install Zend Optimizer, but it didn't work.

After doing some research, I found out that I needed to disable selinux. After doing so, I rebooted. Then I installed Zend Optimizer and rebooted again.

Since then, all my websites have been inaccessible. I can access my server through Plesk control panel, but connection to my websites just timeout.

What can I do to fix this?

Edit :
I can access my sites via FTP as well.

Edit 2 :
I tried starting Apache with the following command :

Quote:

/sbin/service httpd start

...but it keeps on telling me that the service is already in use.
It seems like TCP is bound to port 80.

UK VPS For 15 Websites And VPN Server

Jul 3, 2007

i currently have a reseller server in the states but ive seen for the money im paying (and im not using the space actually) i can get a VPS server here in the UK which i can combine for webhosting and other development projects. I am after a UK based VPS for the following requirements:

Host 15 websites

Access the box remotely and dial-in to the box which needs to be configured as a VPN server (the box will act as a router, i presume masquerading on eth0 for the connected vpn clients to go out through the server and onto the net).

Traffic will not be too high, maybe around 75GB per month.

Around 3-4 websites run forums on (small size phpbb) and the other sites are again small and mostly used for email.

I will need full root access and maximum configurability.

Preferably Suse 10 as i have worked with that before but i am open to suggestions on other OS. I need to configure the pppd service and easier this is via the OS the less time i have to dig in scripts and terminal! I wouldnt mind windows but on a VPS this will be a resource drain so i am happy to get more performance from the box by sticking with smaller footprint of linux.

Plesk for website management, or cpanel, i dont mind either way.

I dont however know how much CPU/RAM i will need, what is a sensible amount? I dont think my requirements are too strenuous, what would be a good sensible amount of RAM to select to allow me to host say 50 web sites in future?

I have heard good things on the forums for the following:

a2b2.com
cheapvps.co.uk
1and1.co.uk

I know you get what you pay for so i do need something reliable, but if people say the service from the above sellers is good i will go for them as the price is fantastic. It would be great to hear of other recommendations also.

VPS You Can Host Multiple Websites?

Apr 27, 2009

So with a VPS you can host multiple websites?

Do certain packages come with WHM where you can make an account for each of your domains?

Also, what is the importance of having more IPs? Does having 1 IP allow me to have only 1 site hosted?

Check Websites Before Dns Propogation

I used to check new websites before dns propagation by adding an entry to windows/system32/drivers/etc/hosts file and used to work perfectly. But now days I think IE7 and Firefox 2 is bypassing the hosts file and the method is not working.

any alternative method to check the website before dns propagation?

DNS - Websites Load Very Slowly

Jan 12, 2008

We have an issue with websites load very slowly in a new server (centos) and we recieve an email from the server stating the following:

IMPORTANT: Do not ignore this email.
The hostname (ns.domain.com) resolves to . It should resolve to
xx.xxx.xxx.90. 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

and when we restart "DNS Server (BIND)" or "named" we get as part of the output the following:

view localhost_resolver: received notify for zone 'domain.com': not authoritative

Please find below the contents of /etc/hosts , /etc/resolv.conf and /etc/sysconfig/network:

/etc/hosts:

::1 localhost6.localdomain6 localhost6
# Do not remove the following line, or various programs
# that require network functionality will fail.
XX.xxx.xxx.90 ns.domain.com ns
127.0.0.1 localhost

/etc/resolv.conf :

#domain domain.com
#search domain.com
#nameserver 127.0.0.1
nameserver xx.xxx.xxx.92
nameserver xx.xxx.xxx.93

/etc/sysconfig/network:

NETWORKING=yes
NETWORKING_IPV6=yes
GATEWAY=xx.xxx.xxx.xx
HOSTNAME=ns.domain.com
DOMAINNAME=domain.com

So what could be wrong with the above settings?

.NET / MS SQL / Unlimited Websites/ 24-7 Support

Nov 9, 2007

I know you have been asked this request 1000 times. I have read many posts and can't find one that answers all of my questions.

I have tried a few hosting services and for one reason or another I end up disappointed*. Below are my requirements.

- .NET 2.0
- MS-SQL (2000+ of course)
- 24/7 support (chat or phone)
- Unlimited websites
- Ability to dynamically create folders in the root directory (odd request, but this takes GoDaddy out of the picture).

Price: As inexpensive as possible (<$12)

Of course I would also prefer to stay away from the oversold servers hosting 1,000,000,000 sites or 1,000,000,000 databases.

Backup Solution For Websites

May 8, 2008

I am about to order a VPS for some backup solutions for my websites, to save my backups etc.

Now, how should I do it ? Let's say one of my main sites are down (server is having a maintenance or the server went down for some unknown reasons, apache crashed, w/e), how should I do it ? I read something about name servers, but I am totally new to this stuff, as I've never dealt with it before.

And no, I do not want any management, it's just a testing box so I can learn it myself.

Anyone got any hints on what to do ? Pref. is if you can give me some links to so some sort of guide(s).
