Constant mirroring

Constant mirroring
I'm not sure how to best explain what I'd like to do, so let me give an example. I used to work in a department that deals with internet security. This department had an "internal" website (only people in the building can get on it) and an "external" website (anyone in the world can get on it -- like unix.com). One day I was told that someone was having trouble FTP'ing a file to the internal server. All he wanted to do was transfer the file between two computers -- he was going to FTP it up with one computer, then get it down from the other computer. He ended up FTP'ing the file to the external server to get the job done. It was deleted from the external server in a matter of minutes.
Apparently, the file he uploaded was "secret information" and it was determined by log files and stuff that someone else had downloaded it in those few minutes it was up there. It was also determined that the person who downloaded the file was actually a script that was constantly mirroring the server.
I now work somewhere else, and we have a number of websites. The management wants us to have an RSS feed (they actually don't even know what RSS is -- they just like to say it) that gets all the new stuff from all of our websites. Instead of making changes to each website, I thought it would be cool to have this same type of script that automatically grabs new information within minutes of it being posted.
I hope that makes sense. Sorry for story-time.
And no, I'm not the person that FTP'd the stuff. I wasn't cool enough to have access to "secrets".

I wonder string constant exists permanently or temporary.
For example,
printf("hello, world");
the function printf access to it is through a pointer. Does it mean storage is allocated for the string constant to exist permanently in memory? :confused: (4 Replies)

ftpconfig
ftpconfig(1M) System Administration Commands ftpconfig(1M) NAME
ftpconfig - set up anonymous FTP SYNOPSIS
ftpconfig [ftpdir] ftpconfig -d ftpdir DESCRIPTION
The ftpconfig script is executed by the super user to set up anonymous FTP. Anonymous FTP allows users to remotely log on to the FTP server by specifying the user name ftp or anonymous and the user's email address as password. The anonymous users are logged on to the FTP Server and given access to a restricted file area with its own file system root. See chroot(2). The FTP area has its own minimal system files. This command will copy and set up all the components needed to operate an anonymous FTP server, including creating the ftp user account, creating device nodes, copying /usr/lib files, and copying timezone data. The passwd and group files set up have been stripped down to prevent malicious users from finding login names on the server. The anonymous file area will be placed under ftpdir. If the ftp user account already exists, then the current FTP area is used, and the system files in it are updated. All other files are left untouched. This command should be run to update the anonymous FTP area's configuration whenever a system patch is installed, or the system is upgraded. OPTIONS
-d Create a new or update an existing ftpdir without creating or updating the ftp user account. Use this option when creating guest FTP user accounts. OPERANDS
The following operands are supported: ftpdir The absolute pathname of the directory under which the anonymous FTP area is set up. EXIT STATUS
The following exit values are returned: 0 Successful completion 1 Improper usage of the command 2 Command failed ATTRIBUTES
