Ways to connect to an FTP

server

We can configure FTP servers

one of two ways.

 Private user-only site. Allows only system

users to connect via FTP and access their

files.

 Anonymous. Allows anyone on the network

to connect to it and transfer files without

having an account.

More ftp commands

 prompt Turns off confirming uploads/downloads  bin Change the transfer of files to binary mode  hash Turn on hash indicators for download/upload  get [filename] Allows to download the specified filename  mget [filespec] Allows multiple download of specified fiels  put [filename] Allows for upload of specified filename

Example… Assume you are required to download the file lan.txt from papa.cdrom.com/pub/games/

2. Type ftp

The system will respond with something

similar to.

>331 Guest login ok, send your complete

e-mail address as password

>Password: (type your email)

3. After the welcome message that may look

something like this.

230 guest login ok, access restrictions apply.

Remote system type is UNIX.

We must now change to the directory

“/pub/games”

Type in

cd pub (this will change to the directory

pub), in this directory we will find

downloadable material.

4. Use ‘cd’ to change into the remaining directories: Type: cd games

5. Use ‘dir’ to find the file: Type: dir l* to get a listing of all files which start with ‘l’. You should see: - rw-rw-r– 1 2066 ftp-game 134868 Jun 30 2001 lan.txt

• Because there is no ‘d’ at the far left, you know that it is a file, not a directory.
• The 134868 is the file size, it is 134,868 bytes (approx. 134 Kb). It was last modified on the 30 th of June 2001.

Type: get lan.txt And type ‘ y ’ when asked to confirm.

• ‘ lan ’ will now download, and will soon be on the computer you ran ‘ ftp ’ from.
• Alternately, if you want to download multiple files, you could type: ‘ mget * ’, this would download all files in the directory; ‘ mget l* ’ would download all files beginning with ‘ l ’.
• If you do not wish to confirm each download one by one, type ‘ prompt ’ to turn that off. If you wish to have a download indicator, type ‘ hash ’.

6b. To upload:

• To upload a file you must be in a directory you are allowed to upload into.
• You would type ‘ put lan.txt ’ if you wished to upload ‘ lan.txt ’ or ‘ mput l* ’ to upload all files beginning with ‘ l ’ for example.
• Make sure that you type ‘ bin ’ again before you upload anything.
