you have to change this:

—————————————————————————————————————–
ini_set(‘include_path’, dirname(__FILE__) . PATH_SEPARATOR . ini_get(‘include_path’));
—————————————————————————————————————–
to:
—————————————————————————————————————–
ini_set(‘include_path’, ‘C:/Inetpub/vhosts/webmail/horde/lib’ . PATH_SEPARATOR . ‘C:/Inetpub/vhosts/webmail’ . PATH_SEPARATOR . ‘C:/Inetpub/vhosts/webmail/horde/pear’ .PATH_SEPARATOR . ini_get(‘include_path’));

If  you are planning to install Yum Server in RHEL5 its very easy to do so.

1. vsftpd->vsftpd-2.0.5.10.e l5.i386.rpm

createrepo-0.4.4-2.0.fc6.n oarch.rpm

You have to follow few step which are as follows :-

Step 1. The most important way is to first of all run by using the mentioned command
Run vsftpd rpm
rpm -ivh vsftpd-*.rpm

Step 2.This will help you to insert the IP address with the help of
iptables -I INPUT -p tcp
dport 20 -j ACCEPT

Step 3. iptables -I INPUT -p tcp –dport 21 -j
ACCEPT

Step 4. iptables -I INPUT -p udp –dport 21 -j ACCEPT
iptables -I INPUT -p udp –dport 20 -j ACCEPT

Step 5. This is for SELinux to access
setsebool allow_ftpd_full_access on

Step 6. Then open the specific file :- vim
/etc/sysconfig/iptables-c onfig and modify below mention
line

IPTABLES_MODU LES=”ip_conntrack_netbios_ns

The customer is the only one who uses the service for his website or web pages, from the server when ever a client use the hosting service. This allows higher performance and security of their website. When users are using shared hosting services for their website many other resources on the server are being used by the website, and it’s be taxed later. The result for this service which is lowering the performance activities of websites. This does not apply to cheap web hosting as a server to be used by the same client, where as there could be single website or multiple sites of the clients.

As technology continues to promote, and "bugs" have been prepared, cloud hosting continues to gain popularity. Many find the technology easier to use, and with all options for the future, now regarded by many as the perfect time to jump on the wagon cloud.

The reason we have to check the OS version is to check if the application we are working with should be running smoothly. The below command example can be use to display the current shell procedure you must go ahead with. If you wanted to check the Plesk control panel version which are running on the server from shell or the SSH the you just need to execute the below commands :

You have to login to your root via shell. As soon as you login to your server.

A user just have to go to the below mentioned path and he will get a sort of display screen.

root@server[#] cat /usr/local/psa/version
———————————
it will show the output as : 9.5.2 CentOS 5 95100504.12
———————————

Or there is another command which is rpm -q psa

root@server[#] rpm -q psa It will show the output as :
———————————
sa-9.5.2-cos5.build95100504.12
———————————

That’s all , easy isn’t it.

Well we can also say that cloud is the nutshell. Many Senior administrator has commented that “Cloud Computing is one of the service which provides developers   which helps developers for on-demand computing platform which helps in multiple areas such as storage to host, scale resources and manage multiple applications. In more simpler way it is all about implementing processes online instead of using the  local machine or software” for e.g Office documents that can be uploaded, extracted and even worked on at the same time online, instead of requiring any of your personal computer to do that kind of work.

Cloud Computing Technical Details :-Thus Cloud Computing gives a complete  freedom to develop the application without looking into the details of network to be used for it. So just forget about building an infrastructure to support your web services and application and start focusing on development alone. I think now you have a little bit of acquittance of about cloud computing is all about, so if you are deciding to go for utilizing this service for your own business, then there are certain basics of cloud computing that you should know.

* Instant Cloud Computing
* Best Storage
* Elastic Load Balance
* Service Delivery
* Complete Database Support
* Bets Server Monitoring

The above 6 aspect are new aspect of cloud website hosting platform . These help us to enhance the  complete productivity of the entire process of marketing your product in front of all your clients. There are plenty of other aspects as well where we need to add a complete delivery of aspect with in the cloud hosting platform.

There are some particular domain on which the cPanel server has stopped receiving e-mail. Or, the address on which your domain is able to receive the e-mail, except from your supplier. Some how you can receive the e-mail just fine, but are receiving error message bounce-backs from Yahoo. How are you going to get the fine-grained information you need to figure out just what is going on.

The answers you seek can be found in exim’s logs.

Getting Started
If you have the sshed into your cPanel server, you have to cd into the directory where exim keeps its logs. Exim puts all of its logs into the following directory:
——————————–
[root@host / ]% cd /var/log
——————————–
These will be the Exim maintains three log files :
——————————–
/var/log/exim_mainlog
/var/log/exim_paniclog
/var/log/exim_rejectlog
——————————–

The Exim Mainlog: This logs are being tracked every single e-mail transaction that your email does or the server handles. This is the go-to log when troubleshooting all e-mail delivery problems.

The Exim Rejectlog: These log files show logs only for the delivery rejections. Such that these can be useful, this is not going to be the first log file you will require to search while troubleshooting the mail problem. For example, if mail is getting through out on the server part, but your mail client is silently failing to download mail, this log will not help you.

The Exim Paniclog: This log has a complete information Regarding the complete exim program itself, and not had any mail transactions. For this reason, it is not suitable for most mail troubleshooting.

Using Exigrep: By using Exigrep you can imagine, on to a server sending and receiving a lot of mail, exim’s log files can get large fast. While normally one would use the grep command to find lines in a file matching a search string, that does not work as well with exim’s logs. One single mail transaction will span multiple lines in the file, and not every line will have the search string you are looking for. The exigrep command works around this problem by finding your search string in transactions, and then helpfully gathering every log entry into separate, complete transactions.

exigrep is run just like grep; simply pass it the search string and the filename of the log file you are searching in:
—————————————————————-
[root@host /var/log/ ]% exigrep “input_string” exim_mainlog
—————————————————————-
Some of the  typical result will look something like this:

How To Read The Exigrep Output :-

The most basic thing to check for when reading exigrep output is the word “Completed” on the last line. If it says “Completed”, then the e-mail in question has been delivered. If you do not see the word “Completed” you will likely see an error, which is a good starting place for tracking down your delivery failures.

These are a parts of the transaction that are also important:

* Timestamp: While in the beginning of each line the important date and time has specified step of the mail transaction occurred.
* from and to: as you can see in the second entry of the example (as indicated with the second timestamp), one line of every transaction shows both who the e-mail is from, and who the e-mail is being sent to
* Transaction ID: Here is each transaction gets its own unique identification string; in the above example, that string is 1Ov4tU-0000Nz-Rm.

Hopefully, understanding the basics of a successful transaction in cPanel’s exim_mainlog will give you a sound basis for starting to troubleshoot thornier exim issues. If you are having trouble making out a particular transaction on your Liquid Web server, do not hesitate to contact Liquid Web’s Heroic Support to find out more.
