You can fudge a random hostname as an alias to 127.0.0.1 in /etc/hosts and by setting the random hostname in /etc/sycconfig/network. This will keep your machine mostly happy but is an ugly hack. > 2) My internal clients cannot access the support.cox.net site at all.

Try tcpdumping on the gateway box while your clients are trying to hit support.cox.net and see what happens. Also take a good hard look at your network setup. Besides, if cox was able to detect NATed connections, they could do far worse things than block access to their support site. > 3) internal clients can't access Mail.

It gets worse when you try and run dns yourself ;-) Matt -- _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
