Simple perl socket code. Any way to improve/simplify it?

prodevel has asked for the wisdom of the Perl Monks concerning the following question:

It's been WAAAY too long since I've visited.

Server:


#!/usr/local/bin/perl

use IO::Socket::INET qw(CRLF);

my $client = IO::Socket::INET->new('blade:12333')
 or die "new: $@";

while (<$client>)
{if ($_ =~ /file: (.*)/)
 {open(FOUT,">>$1") || die "cannot create: $1";}
 elsif ($_ =~ /EOF/)
 {close(FOUT);}
 else
 {print FOUT;}
}

Client:

#!/usr/local/bin/perl

use IO::Socket::INET qw(CRLF);

my $client = IO::Socket::INET->new('blade:12333')
 or die "new: $@";

while (<$client>)
{if ($_ =~ /file: (.*)/)
 {open(FOUT,">$1") || die "cannot create: $1";}
 elsif ($_ =~ /EOF/)
 {close(FOUT);}
 else
 {print FOUT;}
}

Besides the obvious perl security/etc. flags, what do think? I wrote this back in 2004 so I'm curious how it holds up, etc.

Why not preserve sanity, and use scp. Yes - it even works on Windows if you install cygwin. "From there to here, from here to there, funny things are everywhere." -- Dr. Seuss	[reply]

use scp. Yes - it even works on Windows if you install cygwin. No need for cygwin. PuTTY comes with pscp.exe (and psftp.exe) for command line use. If you insist on using a mouse, there is WinSCP that is compatible with PuTTY's way of storing sessions and keys, and it can do scp and sftp as well as classic FTP. All of those programs can use PAgent.exe as SSH authentication agent, so you can work without passwords and type the key's passphrase only once during boot.
