    Why shouldn't a colon (:) be used in a secure password?

    I think it is no security reason, but in UNIX i think in the File /etc/password and /etc/shadow the colon may be used as a seperator. Perhaps you are missunderstanding something. hnd hasso55@yahoo.com

    TCP/IP subnetting help plz

    Only one thing: In IP-Adressing following Adresses are not allowed: 1. All bits are set to 1, because this would be the Broadcast address of the Subnet. 2. All host bits set 0, because this Adress is equal to the Netmask. This disallows host-part 0 and 8191. Therefore you have 8190 addresses...

    Is a firewall on the Internet access point enough?

    If your Firewall works similar a Proxy Server (Is there an other Way?) then this firewall on the Internet Entry Point should be enough. But if your Server is connected to the Internet via the same Adapter like the local Network then you could get Problems. hnd hasso55@yahoo.com
