Posting Files for Anonymous FTP

Public data may be made available to anyone on the Internet via Anonymous FTP. ECE's anonymous FTP server's hostname is ftp.ece.northwestern.edu. To share data using this server, simply make a subdirectory with your username in ~ftparea/pub and then copy your data thereunder. This must be done from the usual xterm command line. It can not be done while logged in via FTP, either anonymous or otherwise.

For example, to make the file myfile available to people on the internet, type the following:

mkdir ~ftparea/pub/MYUSERNAME

chmod 755 ~ftparea/pub/MYUSERNAME

cd ~ftparea/pub/MYUSERNAME

cp ~MYUSERNAME/myfile .

chmod 644 myfile

Immediately after typing these commands, your file becomes available to anyone on the Internet via anonymous FTP. To verify that you've done everything correctly, examine the following example in which we ftp to the server and retrieve our file via anonymous ftp. Bolded commands are typed by the user. The rest is printed by the server.

% ftp ftp.ece.northwestern.edu
