<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">rsync is a widely-used utility to keep copies of a file on two computer systems the same. It is commonly found on Unix-like systems and functions as both a file synchronization and file transfer program. The rsync algorithm, a type of delta encoding, is used to minimize network usage. Zlib may be used for additional compression, and <a href="http://www.hackthesec.co.in/search/label/SSH">SSH </a>or stunnel can be used for data security.</span></span></div>

<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Rsync is typically used to synchronize files and directories between two different systems. For example, if the command rsync local-file user@remote-host:remote-file is run, rsync will use SSH to connect as user to remote-host. Once connected, it will invoke the remote host's rsync and then the two programs will determine what parts of the file need to be transferred over the connection.</span></span></div>

<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span></div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Rsync can also operate in a daemon mode, serving files in the native rsync protocol (using the "<a href="http://www.hackthesec.co.in/search/label/rsync">rsync</a>://" syntax).</span></span></div>

<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Samba is a free software re-implementation of the <b>SMB/CIFS networking protocol</b>, and was originally developed by <b>Andrew Tridgell</b>. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain, either as a<b> Domain Controller (DC)</b> or as a domain member.

The LMHOSTS file is a mapper between the IP address of the domain controller and Netbios name. When you add a Windows computer to the SAMBADOMAIN, Windows tries to find the PDC's IP address.
