What is Web-Based Email ?

Web-Based Email is an Internet-based email system that lets you send and receive
email messages from a Web browser. All you need to use Web-Based Email is an Internet
connection and the Internet Explorer Web browser (Internet Explorer v5.5 or later).
How do I access my Web-Based Email account ?
You can log on to your Web-Based Email account from your Web browser by going
to the Web address for your account. The Web address is the same as your domain
name, except you replace “www” with “email”. For example, if your Web address
is “www.example.com”, your email address is “email.example.com”.

Every Web servers maintain some sort of system that stores information about which pages, images, and files are requested, who requests them, and how many bytes are transferred etc in a file called log file. With log file analysis tools, it’s possible to get a good idea about your visitors such as were they are coming from, how often they return, and how they navigate through your site, which pages are most visited etc.

These log files are used by administrator for effectively managing web server, getting feedback about performance of servers etc.

You can open and read log files in any text editor; for more user-friendly view you can use some stand-alone software or browser-based viewer which will give you more precise data in form of charts/graphs/tables.

The format of the common log file line has the following fields separated by a space:

Remotehost rfc931 authuser [date] “request” status bytes

151.99.190.27 - - [09/Jan/2007:13:06:51] “GET /~bacusHTTP/1.0″ 301 13276

For the above example:

remotrhost : 151.99.190.27
authuser : -
frc931 : -
[date] : [09/Jan/200713:06:51 -0600]
” request ” : ” GET /~bacuslab HTTP/1.0″
status: 301
bytes : 13276

Understanding log fields :

remotehost : Remote hostname or IP address number if DNS hostname is not available.

rfc931 : The remote login name of the user. (If not available a minus sign is typically placed in the field)

authuser :The username as which the user has authenticated himself. (If not available a minus sign is typically placed in the field)

[date] : Date and time of the request.

“request” : The request line exactly as it came from the client. (i.e., the file name, and the method used to retrieve it [typically GET])

status : The HTTP response code returned to the client. Indicates whether or not the file was successfully retrieved, and if not, what error message was returned.

bytes : The number of bytes transferred.

Hello,

The hostname must be FQDN - Fully Qualified Domain Name
hostname is the your server’s name that you want to set. For example if you want to set it server.domain.com. Always set the hostname with the DomainName that you owns.

1. http://IP/whm edit dns zone .. select your domain

server IN A YourSeverIPHere
www.server IN A YourSeverIPHere
OR
if you are using shell then you can simply append following lines there in
# vi /var/named/domain.com.db

server IN A YourSeverIPHere
www.server IN A YourSeverIPHere

Save the file
#service named reload
#rndc reload domain.com

2. WHM >> Basic cPanel/WHM Setup >> Hostname
or
Login to shell /server as a root and fire this command the second parameter will the hostname that you want to set.
hostname server.domain.com

3. Check /etc/hosts file that it is set properly.

Just confirm from some expert that you have set that properly, cause changing the hostname will affect few services on your server if you have not done that properly or have done any spelling mistakewhile setting hostname of your server.

4. Fire hostname on your server if it shows the hostname then you have set it properly.

You have set the hostname now.
Cheers..!!

1. First you will have to decide what nameserver you want to set on your VPS. If you have the domain “mydomain.com” then you can make the nameservers ns1.domain.com and ns2.domain.com.

2. http://IP/whm >> show ip address usage >> Check free IP there or choose your primary and secondary IP Address.
You will need to register nameservers first from registrar end. Login to your registrar’s domain control panel and register the name server or ask them to register the private name server for your domain.

-ns1.domain.com - the Default IP Of your server
-ns2.domain.com - Secondary IP or free IP

Exception : In case if you have just one domain and you have set that name server for your other server and you want to use ns3.domain.com and ns4.domain.com name server for this server then you will have to set the dns for it from the dns zone file of domain.com if you have WHM then you can go to the server where this domain is resolving then open WHM >> Edit a DNS zone >> select domain from the list >> Edit at the end just add this line
ns3 In A First_IP
ns4 In A Second_IP

or if you are using shell then you can simply append following lines there in

# vi /var/named/domain.com.db
ns3 IN A First_IP
ns4 IN A Second_IP

save file.

# service named reload

# rndc reload domain.com

3. http://IP/whm >> Basic cPanel/WHM Setup

Primary Nameserver ns1.domain.com >>
Click on “Assign IP address” and then “Add an A entry for this name server”

Secondary Nameserver ns2.domain.com
Click on “Assign IP address ” and then “Add an A entry for this name server”

4. Once all done you can check if your nameservers have started resolving or not from
http://www.dnsstuff.com/tools/lookup.ch?name=ns1.domain.com&type=A
Once you see the assigned IP address there then it means that the name server for your server are set.

Create new account from your WHM and now you will just need to point your site from your registrar end to these nameservers ns1.domain.com and ns2.domain.com if you want to resolve your site from this server.

You are done with the name server set-up…
Cheers ..!!
