About lynx and ftp
 

Followed after Mathieu,i have installed in my mechine lynx-2.8.5-11 and ftp(ftp-0.17.17,lftp-2.6.3-3,vsftpd-1.1.3-8),but i could not be able to find where are the commands about using lynx/ftp to surf and download data from Internet,how to use them.And i have checked up man pages;The prompt give me "ftp>",what should i do with that?Where should the remote server addresses be typed in?

The man page of "ftp" says the command syntax is "ftp <options> host", it also says "open host [port]" on the ftp> command interpreter wil open a connection to the host.
the lynx man page says the syntax is "lynx [options] [path or URL]", and once inside lynx you can see " '?' for help " on the screen.

If you read the man pages a little better the information you are looking for is in there. With that said I'll throw you one here.

ftp <address of server you want to connect to> [enter]

That will connect you to the ftp server and then you use the different ftp commands from there.
dir, put, get, mput, mget, and many more.

lynx http://<web page address here> [enter]

that will start lynx and go to the web page you specified. read the man page for lynx for more info on how to use it and navigate pages.
