Unless something is broken in the local nameserver. ^^^^^ More often than not, it is broken in the remote nameserver, so that even the login takes a long time as it too does the lookup. Also, again, folks who sit behind certain firewalls don't ever have a reverse lookup (something, IMHO that should be outlawed requireing at least some kind of outside DNS server exists to return fictitious names, ie 2 views of the world DNS firewalling). -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
