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.

Cyberduck (Mac OS X)

Cyberduck is a free, open-source FTP client for Mac OS X with support for most of the usual suspects in transfer protocols in addition to WebDAV and Amazon S3. It also supports Quick Look, Growl, and remote editing with your text editor of choice. Mac users who aren't happy with FileZilla and don't want to shell out any cash for Transmit can flock to the duck for full-featured FTP and then some.

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.

How to use Qos (Quality of Service) on Router

Quality of Service (QoS) is a feature of routers and switches which prioritizes traffic so that more important traffic can pass first. The result is a performance improvement for critical network traffic. QoS equipment is useful with VoIP phones or in LANs with high volumes of local traffic.

SETTING UP QOS 

The QoS settings can be found under Applications & Gaming -> QoS.

There are many ways to assign priority to your VOIP system.  I just used the IP address as shown below.  192.168.1.10 is the LAN private IP of the Asterisk system.

With the priority of the Asterisk box set to high, we should be all set.  It turns out that unless you cap the bandwidth, you will still have QoS problems.  Enter around 85% of your up and down bandwidth in the Uplink and Downlink boxes.  Capping the bandwidth is required to keep the latency low.  Otherwise, your bandwidth is filled up with large packets and the priority settings are not effective for VOIP traffic.  See http://www.dd-wrt.com/wiki/index.php/Quality_of_Service for more information.

With the above settings, VOIP calls are now clear even with other concurrent activities.

UPDATE:

Several people have reported being able to install dd-wrt on v6 WRT54 routers and the QoS configuration is the same.

How to Get Better Wireless Signal

Like all sufficiently advanced technologies, Wi-Fi can feel like magic. But Wi-Fi isn’t magic – its radio waves. A variety of things can interfere with these radio waves, making your wireless connection weaker and more unreliable.

The main keys to improving your wireless network’s signal are positioning your router properly — taking obstructions into account — and reducing interference from other wireless networks and household appliances.

Wireless Router Positioning

Your wireless router’s positioning can greatly affect your coverage area and the strength of your signal. Follow these quick tips to position your router for the best signal.

• Place the router in the middle of your house. If you place the router in a room off to the side of your house, you won’t get as strong a signal on the other side of your house.
• Position the router’s antenna vertically, so that the antenna is standing straight up. Many antennas can be adjusted and lie horizontally, but standing straight up is generally the ideal position.
• Elevate your router away from floors. You’ll get better reception if the router is on a desk, not on the floor.

You should also pay attention to the kinds of materials the router is near. For example, placing the router on a metal desk or up against a metal wall will cause problems. Signals can travel through a wood desk easily, but metal will obstruct the signals.

Other types of obstructions can also cause problems. For example, if there’s a metal filing cabinet between your computer and the router, you may not receive a wireless signal. The same applies to other types of dense objects.

Interference From Other Wireless Networks

Interference from other wireless networks in the area can cause issues with your wireless signal. To determine whether interference is occurring, you can use an app like Wi-FiAnalyzer for Android. It will show you the wireless channels nearby networks are using and recommend the ideal network for you to use — one that isn’t being used by as many networks. This app will also allow you to walk around the area and see where you get the best signal and where the signal is weakest – you can do this with any other device, too.

If multiple wireless networks are competing for the same channel, this can cause problems. To fix this, you can change the wireless channel in your router’s web interface. You can do this even if you don’t have access to a wireless-analyzing app – change the signal to a different channel and then see if your wireless connection improves.

Interference From Household Appliances

A variety of household appliances can cause wireless interference, including cordless phones, baby monitors, and microwave ovens. Depending on the positioning of your wireless router, your networked device, and the appliance, you may even have the wireless network cut out when the microwave or cordless phone is in use.

Problems with cordless phones can be solved by replacing your phones with phones that operate on a different frequency, such as 900 MHz or 1.9 GHz. Cordless phones using the 2.4 Ghz frequency will interfere with wireless networks.

Problems with microwaves can often by solved by positioning the your devices such that the microwave isn’t between your router and the device. it’s also possible that a new microwave will help, if the new microwave has better shielding.

Other devices can also cause problems. For example, older Bluetooth devices can interfere with nearby Wi-Fi signals, although newer Bluetooth devices don’t.

Repeaters, Antennas, and Reflectors

If you need to cover a large area with a wireless signal and your router just isn’t cutting it, you can buy a wireless repeater or range extender. These devices repeat the wireless signal, extending its area. You don’t even need special devices for this – if you have some old routers around, you can use multiple routers to extend your Wi-Fi network.

Depending on your router, you may be able to attach an improved antenna that gives your signal additional range. You can also try building a Wi-Fi reflector that reflects the signal in a specific direction.

Speed Up Your Internet with Google Public DNS

Are you looking for a faster way to browse the Internet and have pages load faster? If so, you might be interested in trying out Google Public DNS, here we will take a look at adding it to your router or home computer.

DNS (Domain Name System) translates an IP address to an easy to remember hostname. If you use your ISPs DNS settings by default, it may not be the fastest way to get to your favourite sites. We have previously recommended the service OpenDNS as speeds are usually faster than your ISP and it offers several other cool options. Google has recently launched a free public DNS service, and we’ll take a look at setting it up on your PC or router.

Add Google DNS to a Window Computer

To add Google Public DNS to your Windows 7 machine, right-click on Network and choose Properties.

Alternatively, you can enter Network and Sharing Center into the search box in the Start Menu.

The Network and Sharing Center opens and you’ll want to click on Change adapter settings which is located on the right side of the screen.

Now right-click on Local Area Connection and select Properties. If you have a wireless connection, right-click on Wireless Network Connection and click Properties.

The Local Area Connection Properties screen opens and you’ll want to highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button.

The Internet Protocol Version 4 Properties window comes up. If you already have DNS settings listed, make sure to copy or write them down in case you want to switch back. Select Use the following DNS server addresses and type in the following for Preferred and Alternate DNS server:

Note: According to Google you can interchange the Primary and secondary address, but don’t use the same number for both.

Preferred DNS Server: 8.8.8.8

Alternate DNS Server: 8.8.4.4

Click Ok and then close out of the remaining windows and reboot your system, then you’ll want to test out the settings. Basically browse around to your bookmarked sites and make sure they display properly.

Add Google DNS to Your Router

In this example we are using a Belkin Wireless Router. Each router varies but the principle is the same. Go into your router configuration settings by typing the Router IP into your browser. Mostly in Home Router it will 192.168.1.1..otherwise if you want to check how to get this IP Address then Go to Network Place Properties and Double Click the "Local Area Network" Click the "Support" tab and there you will find "Default" in the default column IP Address is you Router IP address, 

Open you Browser and put the 192.168.1.1 IP and press Enter, Put the Username & password, Go to the WAN Configuration and find the DNS setting 

Now enter in the primary and secondary DNS addresses and apply changes. Again according to Google you can interchange the Primary and secondary address, but don’t use the same number for both. We set ours up as the following:

Primary:  8.8.8.8

Secondary: 8.8.4.4

After you apply the DNS changes your router may need to restart, where in the case of a Belkin it is a 40 second reboot. After the router reboots, go through and test the settings to verify they work.

Five Mostly Used VPN Apps

Many businesses depend upon the ability to access their servers and documents from multiple locations. To enable that, many take advantage of the Virtual Private Network (VPN). When proposing this to end users, it is very often met with fear and uncertainty. It is change and people don't like change. To make that easier for end users, selecting the right VPN client is key. Some VPN servers (such as Sonicwall and Fortinet) require you use their own proprietary clients. But other VPNs allow the use of third party clients. As for the third-party clients, there are quite a lot of them out there. Some are free, some are cheap, some are worth your time, and some are not. I have gathered together five of the clients I believe to be worth looking into. Each client may or may not meet your VPN needs – that will depend upon the server you are running. But each client offers plenty of features and each offers different levels of user-friendliness.

OpenVPN Client

OpenVPN Client is a full-featured SSL VPN client that seamlessly integrates into an OpenVPN server. This client is as simple to use as any VPN Client and makes connecting to the OpenVPN server a snap. OpenVPN Client is free and is available for Windows, Mac, and Linux. For Windows, this client is compatible with all versions of Windows, including Windows 7, Windows Vista, Windows XP, and Windows 2000. Of course, you will have to have a working OpenVPN server to connect to. Fortunately, that server is incredibly easy to set up.

Gadmin VPN Client

Gadmin VPN Client is another means to connect to the OpenVPN server. This tool is part of the Gadmin Tools suite of administration tools (you can even install a Gadmin VPN Server GUI to help you easily set up an OpenVPN server).

This particular client tool is available only for the Linux platform, but offers tons of options for configuration. Of course, because of the amount of available options, Gadmin VPN Client isn't the best tool for users who are less familiar with how VPNs work.

Shrew Soft VPN Client

Shrew Soft VPN Client is an easy to use client for IPSec Remote Access VPN servers. This client is available for Windows 7, Vista, XP, 2000 (both 32 and 64-bit flavors) as well as the Linux platform.

This client was originally developed to connect to open source servers such as FreeSWAN and OpenSWAN, but now can connect to VPNs by Cisco, Juniper, Checkpoint, Fortinet, Netgear, Linksys, Zywall and many others. Shew Soft VPN Client is free.

VPN X Client

VPN X Client is one of two VPN clients on the list that has a price attached. That price depends upon the license type and how many licenses you need (check out the Pricing page and check outthis comparison matrix.) The VPN X Client will only connect to the VPN X Server. You will find the VPN X Server quite easy to set up and secure enough for small to medium sized businesses.

Viscosity VPN Client

Viscosity VPN Client is a cross-platform client (Windows and Macs) that makes connecting to an OpenVPN server a breeze and will only cost you $9.00 USD.

Viscosity is used in Fortune 500 companies, continuously monitors your OpenVPN connection, fully integrates with OS X's advanced DNS system, can work with AppleScript and Batch/Vbs scripts, and offers Smartcar/token (PKCS#11) support, multiple connections, proxy integration, IPv6, and more.

Bottom line

Having a VPN doesn't mean you have to use a client your end users can't grasp or will put you and your IT budget out of business. These five clients work with different VPN servers and offer different levels of complexity and costs. If you're looking for a new VPN client, or replacing your VPN architecture all together, give these clients a look to see if one of them will fill a hole in your IT infrastructure.

Resolve IP Address Conflict on Network

Each device connected to a network is assigned a unique IP address to identify it to the network. When one IP address is accidentally assigned to more than one device, an IP address conflict occurs. If your computer is using an IP address that is conflicting with another device, you will get a pop-up error telling you that the system has detected a conflict. To find out where the conflicting device is, check the system log for your computer and look up the conflicting device's MAC address by using the IPconfig command.

Find Which Device or User trying to Conflict your Network IP Address

The way to understand, the IP Conflicts.

• Access the Control Panel through the Start Button or you can reach with command prompt (Go to the "Run" and type "control" and press enter)
• Select the "Administrative Tools" on List
• Again select the "Event Viewer" 
• Select the "System" Option in Event Viewer (Local)

• You find the "Red" Error in Source "Tcpcip" double click that one. 

• Now read the description you will find the IP address which is conflict and the Source Mac Address also you will find, Which Hardware try to conflict you IP Address. 
• After get the Mac address download the IPScanner and search the Mac address.
• If you find the Mac address then this user or device try to conflict you IP Address.

How to Find Your Computer Public & Private IP Address ?

An IP address (or Internet Protocol address) identifies each networked computer and device on a network. When computers communicate with each other on the Internet or a local network, they send information to each other’s IP addresses.

Your computer likely has public and private IP addresses. You’ll need the IP address if you’re hosting server software – the client computers will need your computer’s IP address to connect to it.

Public vs. Private IP Addresses

IP addresses can be either public or private. “Public” means an IP address can be reached from the Internet, while “private” means it can’t. For example, in a typical home network, a router has a public IP address on the Internet. The computers, smartphones, game consoles, and other devices behind the router all have unique private IP addresses on the home network. The router acts as an intermediary, forwarding traffic to the local IP addresses that request it. From an outside perspective, all devices on the home network are communicating with the Internet from a single public IP address.

Assuming you’re behind a router performing network address translation, you have two IP addresses that matter. Your computer’s IP address is likely a private IP address, probably starting with 192.168 — is a range of IP addresses specially allocated to private networks. You also likely have a public IP address, which is used when communicating with other computers over the Internet.

For example, if you’re hosting a server on your computer, people on the Internet will need the public IP address from your router to connect to your server. People behind your router — on the same local network as your computer — will need the local IP address from your computer to connect.

If your computer is connected directly to the Internet with no router sitting in between, your computer’s IP address is a public IP address.

Finding Your Private IP Address

To find your computer’s IP Address on Windows, open the Control Panel and select View network status and tasks.

Click the name of your Internet connection to view its status.

Click the Details button in the connection’s status window.

You’ll find the IP address listed in the Network Connection Details window – look for the IPv4 Address field

A quick way to find your IP address in Windows is by running the ipconfig command in a Command Prompt window. You’ll see your IP address in the IPv4 Address row beneath the name of your connection.

 Finding Your Public IP Address

The easiest way to find your public IP address is by asking a website, since that website sees your public IP address and can tell it to you – for example, you can search for what is my ip or what is my ip address on Google. Google will display your public IP address.

You can also access your router’s administration page to find this information. This page displays your public IP address and other information about your Internet connection. Different routers have different administration page layouts and different default local IP addresses – consult your router’s manual if you need more information.

Unlike street addresses, IP addresses aren’t necessarily fixed. Your Internet service provider may regularly assign you a new IP address, just as your router may occasionally assign your devices new IP addresses.

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.
