There are many ways, ranging from easy to hard.

1. Use [http://rsync.samba.org.au|rsync] - it makes keeping two directories in sync very easy and doesn't waste bandwidth. It works over rsh and ssh painless and there are clients for both Win32 and "Unix". Perl is not necessarily involved, but there also is [cpan://Net::RsyncP].
2. Use scp to transfer the files. Very easy, and Perl is not involved, but there also is [cpan://Net::SSH] and some [cpan://SCP] module.
3. Use [cpan://Net::FTP] to transfer your files via ftp. This is less secure because the login and password will be transferred in clear text over the network, but may be a solution.
4. Use [cpan://LWP] and serve your files on the Unix box via a web server. This restricts the access even less than ftp.
5. Write your own server and client in Perl to transfer the files. This is the most ugly and overkill solution, but if you really are in need, a simple netcat-style server and client can pipe a .tar archive over a socket connection easily, and both server and client are typed in in about 10 lines of Perl.

I would go and research the possibilities in the order as I presented them, but if you're really desperate, look at my netcat-style file pipes (sender and receiver) below:

The sender (called nc for hysterical raisins):

#!/usr/bin/perl -w
use strict;
use IO::Socket;

select(IO::Socket::INET->new(PeerAddr => shift, PeerPort => shift) or die "Couldn't connect: $!");
print
  for <>;

The receiver (called cn for reasons obvious):

#!/usr/bin/perl -w
use strict;
use IO::Socket;

# reverse netcat

my $s = IO::Socket::INET->new(LocalAddr => 'sfsifc53', LocalPort => 6666, Listen => 1)
  or die "Couldn't connect: $!";
my $c = $s->accept;
print
  while <$c>;

Most likely, the code above could be vastly simplified by using [cpan://IO::All], but I haven't used that module yet.

Or you can run a web-server on the unix side, and run LWP::Simple on the client side. Anyway, you're too vague. Please answer one or more of the folowing questions:

• Do you want the unix machine to intiate and execute the file transfer?
• Do you have a network connection between the machines?
• Do you maybe run both OS's on the same machine (like a dual-boot system) so you don't actually have the 2 OS's running on the same time?
• Should the transfer be encrypted, or otherwise secured?
• What do you do at the moment, if you transfer the files yourself?

hi,

1) there are two different systems were one is

installed by Unix Operating System and another

one is installed by Windows Operating System.

2)regarding the connection the Unix system is

in Public Ip where the Windows system is in

Private Ip

3) both the Operating systems are not running on

the same machine

4) Actually i want to access a file which is in

the Unix System from my Windows System.....

*** How can i do a share directory-tree from a

unix machine with windows machines using samba

Kindly reply to this

Thanks in advance

Samba is a unix package that allows you to share directories that look to the windows machines like normal "shared folders", so you don't need any special software installed on the windows clients. I would not recommend to use it on a publicly accessible machine, however, for the same reasons you don't use shared folders on a publicly available windows machine.

If you want to get the file off your unix machine from another machine, either install an FTP server on the unix machine and download it using Net::FTP or LWP, install a web-server and download using LWP, or - if you want to have encrypted connections, install an SSH server and use an SSH client library - or do system("scp user@remote:/file/path /local/path") if you have ssh and scp installed locally. Personally I like the ssh client programs from http://www.cygwin.com. If you want to run ssh without having to enter the password each time, you can set up public key authentication .
