Hi,

I agree to have access to remote server via VPN tunnel, to transfer files. I would schedule a crin job to automaticaly access FTP server providing the user name and password. Could you please help me in doing this?

You can put the password and user name in script and do automated ftp transfers.(through cron,at etc)

But this will have the passwords in script file-security issue.

You can also create .netrc file in home directory of user and put user name an dpassword there.

In both cases password is kept in file. In case .netrc file you can put 600 permissions so that it is not readble for others.

FTP script is as follows.

#script for ftp.

ftp -in hostname << EOF
user username password
your stuff here-ftp commands
bye
EOF

Use sftp provided with SSH product.Once you configured SSH-2+public keys are copied to the
server (authorized_keys file) it can work automatically without sending your passwd over TCP/IP.

As mentioned, standard ftp will require the username and password and will be visible unless the cron script has permission 700 so only the owner can read it. The alternative is to use sftp (part of Secure Shell, which must be downloaded from software.hp.com), but this requires the remote server to have the same Secure Shell package and be properly configured. One additional option is to use a .netrc file. The requirements are that the file be 600 permissions and stored in the $HOME directory of the user running the ftp session. For more details, read the man page for .netrc

I think that wu-ftpd 2.6.1 provides a feauture
"restricted-uid" that should do the task.
