But when you wrote 192.168.1.0/255.255.255.0, it means 192.168.1.0 through to 192.168.1.255. Though, practically, it usually means 192.168.1.1 through to 192.168.1.254, since the .0 and .255 ending addresses have their own special uses. Depending on where you're using IP addresses ending with .0 or .255, you will be describing a whole subnet, rather than specific IPs. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
