Hi,
I have a file in which each record is in the format :

12-APR-03 12:20:46.902801 IP 10.60.0.114.2684 > 10.60.0.3.110: . ack 3 +927995843 win 0


I need to parse out the source ip , sorce port , destination ip and port.
I have written the following code :

$file = 'testfile'; open(file_info,$file) or die "Can't open $file : $!"; while (<file_info>) { my ( $src_ip, $src_port ) = /IP\s+(\d+\.\d+\.\d+\.\d+)\/(\d+)/; my ( $dst_ip, $dst_port ) = />\s+(\d+\.\d+\.\d+\.\d+)\/(\d+)/; print "$src_ip $src_port $dst_ip $dst_port \n"; } close(file_info)

and this doesnt seem to work.
Please help.
Thanks, Himi
