ok here is my code 
print "Opening the file\n";                    open(F,"<$pair1[1]");
print "changing the mode to bin\n";
binmode F;
#binmode $new_sock;
my $bufsize = 100;
my $buffer=0;
my $n = sysread(F,$buffer,$bufsize);
print "the value of n is $n\n";                close(F);

my problem starts with the line my $n = sysread... the third last line. the $bufsize is the amount of bytes to be read from the file. because every file will be of a different length so i cant know how much the value will be. so how do i know the size of a file in bytes.
the next problem is receiving the data on the client side.

can any one write a piece of code how to receive the data on the client end.
