How to call automaticly a script when a ftp file is recieved

[Equipe hebergement]

Whe have sereval ftp users (ftp only users) that put files on our server, and we must process those files automaticly.
For the moment, an application check every x minutes if a file is arrived. But there is too much users, and it takes times and load the machine.

How can we make an automated script when a file is recieved ? Without monitoring the log file, is there a more elegant solution ?

Use the macdef command from ftp and .netrc to execute commands to be processed after the transfer. After the 'put' or 'mput'. Call the executable in this fashion.

On UN*X systems, you have to use the file
"$HOME/.netrc"

and on Windows systems (client-wise speaking) there
is an command-line option for it.

/home/ftpuser
$HOME/.netrc

machine SERVER login USER password SECRET macdef init
cd /remote-dir
lcd /local-dir
prompt
binary
mput *.*
exexcutable_script
quit

For example,

home/ftpuser
$HOME/.netrc

machine SERVER login USER password SECRET macdef init
cd /remote-dir
lcd /local-dir
prompt
binary
mput *.*
'Call-to-exexcutable_script_goes_here'
quit

Sorry, but I don't understand how the macdef command can solve my problem.
English is not my native language.

A remote user send a file via FTP on our server.
The server should process this file, so the server should detect that there is a new file and launch a script.

Does I wrong understand you ?

I can't find my example now but here is an alternative.

Put ftp in the sending machine and use the .netrc procedure provided above minus the 'Call-to-exexcutable_script_goes_here'.

Next line put a remsh to invoke the executable from the sending machine into the destination machine where you've just placed the files.

crontab
0 * * * * $HOME/transfer_script

From transfer machine:

Inside transfer_script:

#!/usr/bin/ksh

ftp destination machine
remsh destination machine executable

From destination machine:
.netrc
See above minus 'call...'

Hi everyone,

I have written a korn shell automated script which only transfer files, but how do I transfer all the subdirectories in the filesystem.

Any help would be greatly appreciated. Below is my script.
#!/usr/bin/ksh
cd /FILESYSTEM_NAME
USER=root
PASS=1234
MACHINE=hostname
FTP=/usr/bin/ftp
$FTP -n $MACHINE </dev/null 2>$1
user $USER $PASS
ascii
cd /FILESYSTEM_NAME
mput *

The above script works fine, but what do i need to do in the script so it transfer all the files in the subdirectories of /FILESYSTEM_NAME. Please advise
