How do i set up a FTP server on a machine with dynamic IP ?

Question

I want to set up a ftp server on my machine. My machine has an ADSL broadband connection(Dynamic IP).
So far i have got a fixed domain name from noip.com which gets updated periodically to correspond to the changing IP.
The server daemon is running, but i am not able to connect to the server(my machine).
Configuration
a. Linux kernel 2.6
b. ftp-server-krb5 version 1.3
Any help will be appreciated

Answer 1

You need to check if YOUR isp allows server connections. Many these days block incomming traffic to known server ports. Outbound works but inbound is blocked. Many DSL providers have a statement in the terms of use that says you may not run servers.

Now if you ISP allows you to run servers you should be able to connect as long as noip.com is setup properly.

1.Did you set your hostname on the Linux server to match the"fixed domain name" they gave you?
2.Are you running a router, check to be sure the router forwards port 21 to your servers NAT IP address?
3.Can you "ping" your assigned domain name, try it from a machine "outside" the network and from inside.
4. Are you sure the "service is runing" (check from command line -- service ftpd status? if it is not running type
"service ftpd start" see if any errors occur.
5. Did you assign any ftp users? users have to be setup to connect.

I would bet one of those has not been done.

The FTP server, running FTP server software, listens on the network for connection requests from other computers. The client computer, running FTP client software, initiates a connection to the server. Once connected, the client can do a number of file manipulation operations such as uploading files to the server, download files from the server, rename or delete files on the server and so on. However establishing a FTP connection between 2 client connections is impossible without a Static I.P. address to make the initial connection, like a Telnet connection.

If you're using Windows XP, setting the IP address is easy. I assume the router is acting as your DHCP server and giving your computers their dynamic IP addresses. Even if your router is giving a dynamic IP address, you can still set a static address as long as it's in the same network. First, let's check your IP address. Click on the Start Menu, click on Run, type cmd. When the DOS prompt comes up, type ipconfig /all. Here you'll find the IP address, subnet mask, default gateway, and DNS servers. Write down this information. To statically assign your IP address: 1) Click on the Control Panel 2a) If you're in category mode, click Network and Internet Connections, then click Network Connections 2b) If you're in classic mode, click Network Connections 3) Right click on the appropriate interface and choose properties. 4) In the "This connection uses the following..." section 5) Scroll down until you see the TCP/IP entry and double click it. 6) Click the "Use the following IP address" radio button 7) Enter an address that's in the same network for example 192.168.1.1 to 254 8) Enter the subnet mask 9) Enter the default gateway from the ipconfig screen 10)Click OK, then OK again. That's all there is to setting your IP address to a static address.

I believe that servers should have a static IP. you can setup an FTP server on a machine with dynamic IP there are no issues with that, but how would your clients know which IP to connect to as server, as your server IP keeps changing.

Answer 5

You need a static address for any server services, or dynamic dns, unfortunately ddns is not always that fast updating. Also you need to fix your internal private IP and set up port forwarding on you router to point to it. Ask your ISP about fixed address, they will charge extra for it.
