How Does an FTP Work?In Feburary 2016 19,
In Feburary 2016 19,
File Transfer Protocol (FTP) is the protocol used to transfer files between devices on the Internet. Particularly useful for larger files, FTP is a more robust and more capable protocol than the Hypertext Transfer Protocol (HTTP) used to deliver web pages and smaller files from a server to a client by way of a web browser. Since no special browser is required, FTP is also more universal. All major operating systems, including Mac OS, Windows and Linux allow FTP file transfers directly from the command line. Graphical FTP programs do exist though, and help organize and facilitate bulk file transfers that would otherwise require considerable manual input. By using FTP to transfer files between clients and servers, or between network servers, FTP helps webmasters publish the files that drive the Internet.
FTP Transfers Work in Sessions
In order to transfer a file from a client to a server, or to download a file from a server to a computer, a user must authenticate, or identify himself, when logging on to an FTP server. By authenticating, the user creates a session on the server during which he can transfer or modify as many files as necessary. The authentication process also allows remote hosts to set proper file permissions, keeping users from viewing files or directories to which they do not have access, and allowing an individual user to set read, write, and execute permissions on his own files or subdirectories. When the user session is complete, the user simply disconnects from the server and the session is closed. Some FTP servers also allow 'anonymous' connections, where members of the public can connect anonymously to the FTP server and initiate file transfers; these settings are generally used when publicly available information--like program files released for free--needs to be available for download by knowledgeable users.
FTP Uses Multiple Ports
The File Transfer Protocol is unique among protocols used on the Internet in that it actually works across two ports: one port for issuing commands and conveying other administrative information between the client and server, and a separate port for actually transferring files. Users can also transfer files in either an 'active' or a 'passive' mode, allowing flexibility for file transfers from behind a network firewall or other situation that may present difficulty in transferring files.

Kerberos StepIn Feburary 2016 16,
In Feburary 2016 16,
Before you begin setting up Kerberos on your system, you should know the name of your Kerberos, the hostname of the master and slave Key Distribution Centers (KDC) and how you are going to map your hostnames in the Kerberos realm. You will need to determine the ports that the KDCs and the database access (kadmin) services will use. You will also have to know how frequently the master and slave KDCs will fill the database.You will use the above information to configure the master KDC. The master KDC configuration files will be found at '/etc/krb5.conf' and '/usr/local/var/krb5kdc/kdc.conf' and can be edited in any text editor. The 'krb5.conf' file contains information about where to locate the KDCs and admin servers, as well as the host name mapping information. The 'kdc.conf' file contains the default information used when issuing Kerberos tickets. Open the '/etc/krb5.conf' and edit the 'login,' 'realms' and 'domain_realm' values so that they are correct for your system. Change the '/usr/local/var/krb5kdc/kdc.conf' so that it reflects the correct information for your KDC server.The next step is to create the database. Open a terminal and type the command 'kdb5_util.' You will be asked to provide a master key. This should be a string of letters, numbers and special characters similar to a password. This key will be stored in a stash file on the KDC's hard drive. If you would rather be prompted for the key whenever Kerberos starts, you can choose to not create the stash file.Finally, you will create the Access Control List (ACL) and add at least one administrator to it. The ACL is a user created text file that is called '/usr/local/var/krb5kdc/kadm5.acl.' This file should have the administrator listed in the form:
Kerberos_principal permissions [target_principal] [restrictions]
Once the ACL list is created, issue the command 'kadmin.local' and add each principal to the database. Start the Kerberos daemons with the command '/usr/local/sbin/krb5kdc; /usr/local/sbin/kadmin.'
Creating the Keytab File
The keytab file is used to decrypt the Kerberos tickets and determine whether the user should have access to the database. In order to create this file, type the command 'kadmin.local' again. This will provide you with a prompt where you will type the command: 'ktadd -k /usr/local/var/krb5kdc/kadm5.keytab kadmin/admin kadmin/changepw' to create the keytab file. Replace the section '/usr/local/var/krb5kdc/kadm5.keytab' with the keytab location that was specified in the '/usr/local/var/krb5kdc/kdc.conf' file. Type 'quit' to exit the 'kadmin' utility.
Configuring the Slave KDCs
To create the slave KDCs, you will issue the 'kadmin.local' command a third time. At the prompt, issue the command 'addprinc-randkey host/example.com' for the Master and each slave. Use the host name of each KDC in place of 'example.conf.' This will create host keys for each of the KDCs. Next, extract the keys on each of the slave KDCs by starting the 'kadmin' utility on each of the slaves and issuing the command 'ktadd host/MasterKDC.com.' Replace 'MasterKDC.com' with the host name of the master KDC.For the database to be propagated from the master KDC to the slave KDCs you will have to create a file called '/usr/local/var/krb5kdc/kpropd.acl.' This file must contain the principals for each of the KDCs in the form 'host/example.com.' Each principal should be placed on its own line. Next, edit the '/etc/inetd.conf' file on each of the KDCS and add the following lines:
krb5_prop stream tcp nowait root /usr/local/sbin/kpropd kpropd
eklogin stream tcp nowait root /usr/local/sbin/klogind klogind -k -c -eEdit the '/etc/services' file on each of the KDCs and add the following lines:
kerberos 88/udp kdc # Kerberos authentication (udp)
kerberos 88/tcp kdc # Kerberos authentication (tcp)
krb5_prop 754/tcp # Kerberos slave propagation
kerberos-adm 749/tcp # Kerberos 5 admin/changepw (tcp)
kerberos-adm 749/udp # Kerberos 5 admin/changepw (udp)
eklogin 2105/tcp # Kerberos encrypted rlogin
Propagating the Database
Propagating the database is done from the Master KDC. Issue the command '/usr/local/sbin/kdb5_util dump /usr/local/var/krb5kdc/slave_datatrans' to create a dump of the database. Next, issue the command ' /usr/local/sbin/kprop -f /usr/local/var/krb5kdc/slave_datatrans Slave-1.example.com' to manually propagate the database on each of the slaves. These steps will need to be completed on a regular basis. The easiest way to do this is to create as script and run the script as a cron job. The script should look like:!/bin/sh
kdclist = 'slave-1.example.com slave-2.example.com'/usr/local/sbin/kdb5_util 'dump
=> /usr/local/var/krb5kdc/slave_datatrans'for kdc in $kdclist
do
/usr/local/sbin/kprop -f /usr/local/var/krb5kdc/slave_datatrans $kdc
done
Of course, change the host names to reflect the values for your system.
Create Stash Files on the Slaves
The final step to setting up Kerberos is to create stash files on the slave KDCs. On each of the slave KDCs issue the command 'kdb5_util stash' and provide the master key when prompted. Once that is completed, you can start the 'krb5kdc' daemon on each slave with the command '/usr/local/sbin/krb5kdc/.'

How to Write to a Remote File in PHPIn Feburary 2016 15,
In Feburary 2016 15,
Open your PHP file in a text editor, such as Windows Notepad.
Connect to a remote FTP server. Open a file with the 'fopen(address, mode)' command. The mode needs to be set to 'w' for writing. For example, '$my_file = fopen ('ftp://ftp.myserver.com/myfile.txt', w);' will anonymously connect you to the ftp server and create a new file called 'myfile.txt' that you can write to. To use a non-anonymous account, change the address to use the format 'ftp://username:password@ftp.myserver.com/file'.
Write data to the file using the 'fwrite(handle, string);' command. For example, 'fwrite ($my_file, 'my text');'.
Close your connection once you are done writing to the file with the 'fclose(handle);' command. For example, 'fclose($my_file);'. Once executed, the new file will now have been written to and saved on the remote server.
Save the PHP file.
