Well, Stevens' latest edition of UNP is much different than the previous edition I read. Lots of IPV6 stuff. However, there are system calls that Redhat 6.2 doesn't have like getaddrinfo. So I grabbed my Comer/Stevens book. He doesn't actually have a code example for the preforking server, but his code seems to focus in IPV4 stuff. Looks like I'll have to mix and match stuff from both books to get what I want.
