Following are the TCP/IP Application protocols:
1.DHCP:

DHCP Dynamic Host Configuration Protocol is defined by RFC’s 2131
and 2132.DHCP is Dynamic Host Configuration
Protocol (DHCP) allows IP addresses to
be allocated to hosts on an as-needed basis.DHCP lets a host
‘borrow’ an IP address from a pool of IP addresses; when the
address is no longer required it is recycled and made available for
use by other host. DHCP also allows a host to retrieve a
verity of configuration information.

DCHP depends on UDP to carry packets between the client and server
tasks.

2. DNS

The DNS (Domain Name System) provides ondemand dynamic
translation between human-readable names (like www.mydoamin.com)
and the numeric addresses actually used by IP (like
192.169.10.28). The basics of DNS operation are defined in RFC’s
1034, 1101, 1876, 1982 and 2065.

A very widely-used implementation of DNS called BIND
(Berkeley Internet Name Domain)
DNS uses both UDP and TCP. It used UDP to carry simple queries and
responses but depends on TCP to guarantee the correct and orderly
delivery of large amounts of bulk data (eg zone configurations) across the network.

3. FTP

File Transfer Protocol (FTP) provides a mechanism for transfering data
files between various systems. In addition to the fundamental PUT and GET
operations, FTP provides a small number of file management and
user authentication facilities. FTP uses port 21

FTP depends on TCP to guarantee the correct and orderly delivery
of data across the network.

4. HTTP

Hyper Text Transfer Protocol (HTTP) is the protocol used to publish
Web pages across an internet. HTTP depends on TCP to guarantee the
correct and orderly delivery of data across the network.

5. IMAP

Interactive Mail Access Protocol (IMAP) allows clients to
manipulate email messages and mailboxes that reside on some server
machine. The current version of IMAP is Version 4, IMAP is more powerful
and more complex than the other widely-used mail-reading protocol
POP.

6. NFS

Network File System (NFS) allows files stored on one machine (the
“server”) to be accessed by other machines (the “clients”) as
though the files were actually present on the client systems. NFS
is defined in terms of a Remote Procedure Call (RPC) abstraction
which in turn formats its packets according to a
processor-independent eXternal Data Representation (XDR).

NFS is most often used over UDP. UDP does not guarantee packet delivery or ordering, so
when NFS runs over UDP the RPC implementation must provide its own
guarantees of correctness.

7. NNTP

Network News Transfer Protocol (NNTP) is used to propagate netnews
postings (including Usenet postings) between systems.

8. NTP

Network Time Protocol (NTP) is used to synchronise time-of-day
clocks between various computer systems. The current version of
NTP is Version 3, defined in RFC 1305.

9. POP

Post Office Protocol (POP) allows clients to read and remove email
from a mailbox that resides on some server machine. The current
version of POP is Version 3, usually referred to as POP3. POP uses port 110

10. Rlogin

Remote Login (rlogin) provides a network terminal or “remote
login” capability. Rlogin is similar to Telnet but it adds a
couple of features that make it a little more convenient than
Telnet.

11. Rsh

Remote Shell (rsh) is an r-command that provides for remote
execution of arbitrary commands. It allows you to run a command on
a server without having to actually log in on the server. More
importantly it allows you to feed data to the remote command and
retrieve the command’s output without having to stage the data
through temporary files on the server.

12. SMTP

Simple Mail Transfer Protocol (SMTP) is used to deliver email from
one system to another. The port used by SMTP is 25.
13. SNMP

Simple Network Management Protocol (SNMP) provides a means of
monitoring and managing systems over a network. SNMP defines a
method of sending queries (the GET and GET-NEXT primitives) and
commands (the SET primitive) from a management station client to
an agent server running on the target system, and collecting
responses and unsolicited event notifications.

14. Ssh

Secure Shell (ssh) provides remote login and execution features
similar to those of the rsh and rlogin r-commands, but ssh
encrypts the data that is exchanged over the network. Encryption
can protect sensitive information, and it is not uncommon for
security-conscious administrators to disable plain rsh and telnet
services in favour of ssh.

The SSH protocol used by the ssh command has also been used to
build a secure file transfer application which can be used as an
alternative to FTP for sensitive data.

15. Telnet

Telnet provides a network terminal or “remote login” capability.
The Telnet server accepts data from the telnet client and forwards
them to the operating system in such a way that the received
characters are treated as though they had been typed at a terminal
keyboard. Responses generated by the server operating system are
passed back to the Telnet client for display.

16. X Window System

The X Window System allows client programs running on one machine to control the graphic
display, keyboard and mouse of some other machine or of a
dedicated X display terminal.

Cpanel do not provide any utility to convert .dmp file to MySql database. There are third party software which can be use to convert .dmp file to MySql database.

Excel-to-MySQL is a program to convert Microsoft Excel spreadsheets into MySQL databases. Depending on your privileges on the target MySQL server you can export MS Excel data into new database or overwrite the contents of an existing MySQL database.

Requirements

• Windows 2000/XP or Windows NT 4 with Internet Explorer 5 or later or Windows 98/ME or Windows 95 with Internet Explorer 5 or later
• At least 32 MB of available memory

VServer user’s option

If you are using Virtual Server hosting you probably have no sufficient privileges to create new databases on the target MySQL server. For this case we recommend the following approach:

1. ask your Virtual Server administrator to create blank database for you
2. run Excel-to-MySQL and select this database as the conversion target
3. click “Yes” when you will be asked if you’d like to overwrite existing MySQL database

When you complete these steps, the entire contents of the source MS Excel spreadsheet will be imported into the specified MySQL database.

MySQL dump file

Excel-to-MySQL allows users to perform deferred conversion and get more control over the process. Following this way, the program stores the contents of the data source into a local dump file instead of moving it to MySQL server directly. The resulting file contains MySQL statements to create all tables and to fill them with the data. You will be able to import this file into existing MySQL database via MySQL client as follows:

mysql.exe –host=… –user=… –password=… -vvf {MySQL database name}

Hello,

The Plesk Hosting software package is a commercial hosting automation software. It allows to setup set up new websites, email accounts, and DNS entries through a web-based interface.

The php gd package contains a dynamic shared object that will add support for using the gd graphics library to PHP. If users are using popular CMS software such as Wordpress, you need GD support.

Adding GD graphic libraries support to php is quite easy job w/o breaking Plesk software.

Red Hat Enterprise Linux

Type following two command as root user:
# up2date php-gd
# /etc/init.d/httpd restart


Cent OS or Fedora Core Linux

Type following two command as root user:
# yum install php-gd
# /etc/init.d/httpd restart

Verify that php gd support loaded

Type any one of the following command:
# php -m | less
# php -m | grep gd

Enjoy..

Forgot the MySQL root password :

First you will have to stop the MySQL service on the server.

# service mysqld stop

Start MySQL as

# /usr/bin/safe_mysqld –skip-grant-tables &

Or

# /usr/bin/mysqld_safe –skip-grant-tables &

safe_mysqld is a script that starts mysqld and traps any forceful terminationof the MYSQL server and it privents any database corruption.

Change the password for root user as

# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD(’new_password’) WHERE user=’root’
mysql> FLUSH PRIVILEGES;
mysql> exit;

Start the MySQL service:

# service mysqld start

TCP -Transmission Control Protocol -It is a Protocol used in connection oriented networks

It breaks the data into packets and also supports error correction.

It supports error correction in the transmitted data and thus it is a reliable protocol. TCP is connection orinted protocol means it will get an acknoldgement for the packet it has forwarded.

It is synchronous in nature.

TCP-Not Used for real time applications. But it is used with applications such as web servers, Ftp uses TCP protocol.

It is bit slow compaire to UDP.

UDP - User Datagram Protocol - It is a protocol used in connectionless networks.

In UDP the data is transfered as packets. It also breaks the data into packets like the TCP, But it does not support error correction.

It does not support error correction in the transmitted data and it is not a reliable protocol like TCP.

It is asynchronous in nature.

UDP-Mostly used for real time applications. UDP is use for applications like video streaming and online gaming, where lost packets don’t need to be retransmitted.

It is more speedy than TCP.

1. Do we allow EXE files to live and run as CGI?

Answer: We have no problems with allowing EXE files to live and run as CGI.

2. If you submit for a shared hosting, Will you get an anti virus installed on
Web mail you provide?

Answer: Anti-virus is installed on the mail servers and it will protect your web mail as well.

3. Do our servers support secure ftp and do we have basic templates
for websites?

Answer: Our servers support secures FTP and this feature is available on all of our hosting plans. And we do offer any website templates.

4. If it would be possible to switch servers, and how would you go about switching your
domain (www.xxxx.com) over to micfo servers?

Answer: In order to switch servers, you have to cancel/terminate your account and setup a new account with Micfo International L.L.C.

If tomcat is failed on the server, Then login to the server with root login details and Goto, ————————-

cd /usr/local/jakarta/jakarta-tomcat-5.5.9/bin/

————————-

Check the running processes as

ps aux | grep tomcat

Then stop all tomcat processes. You can stop it with the script as ————————-

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ./shutdown.sh ————————- [This script will stop the tomcat processes that are running]

In order to fix tomcat run following command under /usr/local/jakarta/jakarta-tomcat-5.5.9/bin

————————-

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# java -jar bootstrap.jar

————————- [This will set java environment for tomcat on the server]

Then start the tomcat service with the script

————————-

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ./setclasspath.sh

root@servername [/usr/local/jakarta/jakarta-tomcat-5.5.9/bin]# ./startup.sh ————————- [This script start tomcat on the server]

You will have to stop and restart apache service on the server many times before you run startup.sh script.
