Free Five Faster FTP Clients

If you work corporate or open internet environment you should be require the FTP server to secure your data, first of all we should know "What is FTP Server ? " and why we've require to implement it.

What is FTP Server ?

FTP stands for "file transfer protocol." FTP powers one of the fundamental Internet functions and is the prescribed method for the transfer of files between computers. It is also the easiest and most secure way to exchange files over the Internet

Why is require for business environment ?

Setting up an FTP server becomes necessary for businesses that manage their own network and need to establish a file transfer connection to facilitate the exchange of documents between company employees. It is also needed by web hosting companies that empower their clients to upload websites to the hosting servers they are managing. Also, the installation of an FTP server application is a good solution if you're a person who needs to share a large number of files over the Internet.

Where we get FTP Client 

Most computer operating systems already come with an FTP client; however, it is not user-friendly.  Start up a command prompt window, type "ftp" and then press “enter.”  Chances are you will be greeted by an "ftp>" prompt. Unless you are well-versed with using command lines and enjoy typing, there are much easier ways to FTP.

FTP Explorer is an FTP client application.  It is designed to make FTP simple and hassle-free. Most people agree it is much easier to use than a command line FTP client. 

  or and access from anywhere or modify do your date you need FTP client

Five Best FTP Clients

WinSCP (Windows)

WinSCP, Windows Secure Copy, is a free, open-source FTP client. Supporting both SFTP and SCP protocols (upshot: secure transfers), WinSCP is fast and lightweight while still supporting advanced features like remote text editing. When you open a plain text file, WinSCP can open the file in your text editor of choice. Every time you save the file, it transparently saves and uploads the changes to the remote server. Added bonus: a portable version is available. WinSCP's synchronized browsing feature is also worth a look.

Transmit (Mac OS X)

Transmit is a shareware ($30) FTP client packed to the brim with innovative features. It covers all of the usual suspects, including remote file editing and folder sync, and it's also got tons of Mac-centric features like a Dashboard widget, .Mac syncing of your favorites (bookmarked FTP servers), and droplets for quick drag-and-drop uploading to favorite locations, inline previews, and Automat or support. Transmit can even do server-to-server transfers from one server's tab to another's. Despite its $30 price tag, Transmit has even got some Windows users version

FireFTP (All Platforms with Firefox)

FireFTP is a Firefox extension that integrates a powerful FTP client directly into our favorite browser. FireFTP isn't the most feature-rich client of the bunch, but if all you need is a simple FTP client for the occasional upload or download, FireFTP is more than up for the job. Even better: You don't have to install a separate program for FTP, since it all runs from the warm and fuzzy comfort of the 'fox. If you're running Portable on your thumb drive, you can take FireFTP with you wherever you go.P

FileZilla (All Platforms)

FileZilla is a free, open-source FTP client for Windows, Mac, and Linux. Due to its price tag (or lack thereof), cross-platform support, and ease of use, FileZilla is a go-to option for many users new to FTP. Users stick around because FileZilla is a fast, full-featured (it also has remote file editing), and reliable FTP client in constant development. There's even a portable version you can toss on your thumb drive to use FileZilla on the go. Finally, if you're a Windows user you can even use FileZilla to build your own home FTP server.

How to test Internet Speed through Command Prompt

Anybody who wants to test their connection speed can easily do so from a speed test web site — but that isn’t very geeky. Here’s how to do a test from the terminal prompt instead.

(Note: If you are using Windows, you’ll want to either have Cygwin installed, or have a copy of curl or wget installed. On the Mac you can use curl, but if you prefer wget, you’ll need to install that.)

Testing Internet Connection Speed with Curl

This is pretty simple. Just copy and paste the following command:

curl -o /dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip

The first thing to point out is that we’re using a test file from Softlayer, but if your connection is really fast, you might want to use a larger file from Thinkbroadband to properly test. Secondly, that -o switch is the lower case form of the letter O. It’s not a zero, and if you omit it, your terminal will turn into crazyville since curl will try to output to the screen — it’s also important because we’re outputting the file to /dev/null, which means it’ll basically be automatically deleted.

Testing Internet Connection Speed with Wget

If you prefer using wget, or that is what you have installed, the switch is the same. That is a capital letter “o” and it sends the output straight to null, so you don’t have any files to delete.

wget -O /dev/null http://speedtest.sea01.softlayer.com/downloads/test100.zip

This file is only 100 MB, so if you have a really fast connection, this isn’t going to work very well, and you’ll want to find a bigger file to download from the site linked above.

What is a DMZ ?

In computer networking, DMZ is a firewall configuration for securing local area networks (LANs).

In a DMZ configuration, most computers on the LAN run behind a firewall connected to a public network like the Internet. One or more computers also run outside the firewall, in the DMZ. Those computers on the outside intercept traffic and broker requests for the rest of the LAN, adding an extra layer of protection for computers behind the firewall.

Traditional DMZs allow computers behind the firewall to initiate requests outbound to the DMZ. Computers in the DMZ in turn respond, forward or re-issue requests out to the Internet or other public network, as proxy servers do. (Many DMZ implementations, in fact, simply utilize a proxy server or servers as the computers within the DMZ.) The LAN firewall, though, prevents computers in the DMZ from initiating inbound requests.

DMZ is a commonly-touted feature of home broadband routers. However, in most instances these features are not true DMZs. Broadband routers often implement a DMZ simply through additional firewall rules, meaning that incoming requests reach the firewall directly. In a true DMZ, incoming requests must first pass through a DMZ computer before reaching the firewall.

How to make VLAN on Cisco Switch

Have you ever wondered what a Virtual LAN (or VLAN) is or been unclear as to why you would want one? If so, I have been in your place at one time too. Since then, I have learned a lot about what a VLAN is and how it can help me. In this article, I will share that knowledge with you.

What is a LAN?

Okay, most of you already know what a LAN is but let’s give it a definition to make sure. We have to do this because, if you don’t know what a LAN is, you can’t understand what a VLAN is.

A LAN is a local area network and is defined as all devices in the same broadcast domain. If you remember, routers stop broadcasts, switches just forward them.

What is a VLAN?

As I said, a VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLAN’s, a switch can create the broadcast domain.

This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain.

Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.

Are VLANs required?

It is important to point out that you don’t have to configure a VLAN until your network gets so large and has so much traffic that you need one. Many times, people are simply using VLAN’s because the network they are working on was already using them.

Another important fact is that, on a Cisco switch, VLAN’s are enabled by default and ALL devices are already in a VLAN. The VLAN that all devices are already in is VLAN 1. So, by default, you can just use all the ports on a switch and all devices will be able to talk to one another.

When do I need a VLAN?

You need to consider using VLAN’s in any of the following situations:

• You have more than 200 devices on your LAN
• You have a lot of broadcast traffic on your LAN
• Groups of users need more security or are being slowed down by too many broadcasts?
• Groups of users need to be on the same broadcast domain because they are running the same applications. An example would be a company that has VoIP phones. The users using the phone could be on a different VLAN, not with the regular users.
• Or, just to make a single switch into multiple virtual switches.

Why not just subnet my network?

A common question is why not just subnet the network instead of using VLAN’s? Each VLAN should be in its own subnet. The benefit that a VLAN provides over a subnetted network is that devices in different physical locations, not going back to the same router, can be on the same network. The limitation of subnetting a network with a router is that all devices on that subnet must be connected to the same switch and that switch must be connected to a port on the router.

With a VLAN, one device can be connected to one switch, another device can be connected to another switch, and those devices can still be on the same VLAN (broadcast domain).

How can devices on different VLAN’s communicate?

Devices on different VLAN’s can communicate with a router or a Layer 3 switch. As each VLAN is its own subnet, a router or Layer 3 switch must be used to route between the subnets.

What is a trunk port?

When there is a link between two switches or a router and a switch that carries the traffic of more than one VLAN, that port is a trunk port.

A trunk port must run a special trunking protocol. The protocol used would be Cisco’s proprietary Inter-switch link (ISL) or the IEEE standard 802.1q.

How to configure VLAN on a Cisco Switch?

VLAN stands for virtual LAN and technically we can say, a VLAN is a broadcast domain created by switch. When managing a switch, the management domain is always VLAN 1, the default VLAN. All ports of switch are assigned to VLAN 1 by default.  VLAN increase the performance of a network because it divide a network logically in different parts and limit the broadcasts.Any member of VLAN 2 can not talk with any member of VLAN 3 without router but all the members of VLAN 2 and VLAN 3 can talk with other members within their VLANs.This Lab will also help how VLANs can be used to separate traffic and reduce broadcast domains. To create a VLAN, first enter global configuration mode to run the following commands. Configuration to create VLAN 2 

SwitchA(config)#configure terminal	(enter in global configuration mode)
SwitchA(config)#vlan 2	(defining the vlan 2)
SwitchA(config)#vlan 2 name marketing	(assigning the name marketing to vlan 2)
SwitchA(config)#vlan 2 name marketing	(assigning the name marketing to vlan 2)
SwitchA(config)#exit	(exit from vlan 2)
Configuration to create VLAN 3
SwitchA(config)#configure terminal	(enter in global configuration mode)
SwitchA(config)#vlan 3	(defining the vlan 3)
SwitchA(config)#vlan 3 name management	(assigning the name management to vlan 3)
SwitchA(config)#exit	(exit from vlan 3)
Now assigning the ports 2 and 3 to VLAN 2, it must be done from the interface mode. Enter the following commands to add port 2 and 3 to VLAN 2.
SwitchA(config)#configure terminal	(enter in global configuration mode)
SwitchA(config)#interface fastethernet 0/2	(select the Ethernet 0 of port 2)
SwitchA(config-if)#switchport access vlan 2	(allot the membership of vlan 2)
SwitchA(config-if)#exit	(exit from interface 2)
Now adding port 3 to VLAN 2
SwitchA(config)#interface fastethernet 0/3	(select the Ethernet 0 of port 3)
SwitchA(config-if)#switchport access vlan 2	(allot the membership of vlan 2)
SwitchA(config-if)#exit	(exit from interface 3)
Now assigning the ports 4 and 5 to VLAN 3, enter the following commands to add port 4 and 5 to VLAN 3.
SwitchA(config)#configure terminal	(enter in global configuration mode)
SwitchA(config)#interface fastethernet 0/4	(select the Ethernet 0 of port 4)
SwitchA(config-if)#switchport access vlan 3	(allot the membership of vlan 3)
SwitchA(config-if)#exit	(exit from interface 4)
Now adding port 5 to VLAN 3
SwitchA(config)#interface fastethernet 0/5	(select the Ethernet 0 of port 5)
SwitchA(config-if)#switchport access vlan 3	(allot the membership of vlan 3)
SwitchA(config-if)#exit	(exit from interface 5)

         

To show the VLAN interface information, run the command show vlan.
