 FTP is not an encrypted transmission, which means any data sent over it, including your username and password could be read by anyone who may intercept your transmission. If you're wanting a more secure transmission we suggest using  SFTP .

Once in FTP> Type: open ftp.example.com In the above example, you'd substitute example.com for the name of your domain you're wanting to connect to.

For troubleshooting why the Web App Server says the port is in use... Windows XP and 2003 have the tools built-in to determine what process is using a specific TCP/IP port. If you are using some other version of windows, you will not be able to continue as below. But there are still a number of third-party tools available which can be downloaded instead. One such tool that has been used successfully by several people is  fport . From a command prompt, run  netstat -o . This will output a list of ports, along with the PID (process ID) that has that port open. The output looks something like: Code: C:\Documents and Settings\Administrator>netstat -o Active Connections Proto Local Address Foreign Address State PID TCP WEBAPPSERVER2:80 199.90.113.2:57434 TIME_WAIT 2636 TCP WEBAPPSERVER2:80 199.90.113.2:57589 TIME_WAIT 2636 TCP WEBAPPSERVER2:80 199.90.113.2:57600 TIME_WAIT 2636 TC...

I. Register for Amazon EC2 1. Go to aws.amazon.com and make an account. 2. Read over all appropriate charges that you will incur. You'll be charged for bandwidth, disk io, the server itself, ebs volumes, etc. There is a free tier for new customers but you will probably incur some extra charges outside of that tier. 3. Understand pricing structure of EC2 servers. There are 3 pricing tiers. Servers are charged per hour of usage. On Demand: Most expensive but pay as you go and guaranteed server time. Set up within seconds usually. Reserved: Same as on demand but you pay for access to lower prices for 1 or 3 years with a one time fee. Spot: (what i generally use) based on bid for unused servers. Cheapest prices of all. Set a maximum price you're wiling to pay for server time and a server is obtained through a bidding process. Usually costs 1/3 of price of on demand instances. If current bid prices rises above your maximum bid your server will be shut down and your data...

If you ever need to check the status of your DNS records, Windows has a built-in tool for just that task. There are a number of reasons you may want to do this, for example to check that any updates are correct or to troubleshoot issues accessing a particular service. Checking For a Record Getting an Authoritative Answer Checking When a Cached Record Will Expire Summary To access the tool you need to open up a command prompt, you should be able to find this under Start > All Programs > Accessories > Command Prompt Checking For a Record To check for a specific record you need to specifiy the record type, e.g. A, MX, TXT, and the host name you want to check. The following example shows how to check for any A records for rackspace.co.uk. C:\Users\Administrator>nslookup -type=A rackspace.co.uk Server:  cachens1.lon.rackspace.com Address:  83.138.151.80 Non-authoritative answer: Name:    rackspace.co.uk Address:  21...

DNS (Domain Name System): frequently asked questions Applies to  Windows Vista Here are answers to some common questions about DNS. Hide all What is DNS (Domain Name System)? Websites have both a "friendly" address, called a Uniform Resource Locator (URL) and an IP address. People use URLs to find websites, but computers use IP addresses to find websites. DNS translates URLs into IP addresses (and vice versa). For example, if you type http://www.microsoft.com into the address bar in your web browser, your computer sends a request to a DNS server. The DNS server translates the URL into an IP address so that your computer can find the  Microsoft  web server. What is the last part of a URL? The last part of a URL is called a  top-level domain name (TLD) . TLDs identify different types of websites. Here are some common TLDs and what they stand for: Top-level domain Stands for .com commercial (business) site .net Inte...
