You can check that sort of thing out by using nslookup on hostnames that you're pretty sure haven't been looked up from your host recently. 2) Perhaps the services you're trying to conenct to are all being launched out of inetd? This can be a real performance problem, especially if the services are handled by programs with a high startup overhead. Also, FreeBSD 3.2's inetd uses TCP Wrappers to validate connection attempts. Perhaps you've specified the slow PARANOID option in one or more of your rules in /etc/hosts.allow ? 3) Perhaps your machine is very busy. What's the load average on the box looking like? What does the top program show you? 4) Perhaps you're using the wrong duplexing on your ethernet card. This, however, is something you'd have to know. It's not something someone else can tell you about your own network. As you can see, the problem you're having could have a number of causes. Good luck with your investigations. :-) later, Sheldon.
