UNIX for Advanced & Expert Users

I was given this question and cannot seem to answer it. "Identify 4 network and 4 sytem files that control how the system and network function (other than rc files)." The problem is I only know of rc files. Can anyone help?

hi,

for which OS do you need to know that ?

Here you have an answer, but this is mostly for OpenBSD:
/etc/myname - contains host name
/etc/defaultdomain - contains the domain name
/etc/mygate - contains the address of the default gateway
/etc/hostname.if_name - contains the configuration of the specified interface (if_name = xl0, fxp0, etc)
/etc/resolv.conf - contains the name of the dns resolver, and search domain
/etc/dhcpd.conf - configuration file for DHCP daemon
/etc/dhcpd.interfaces - a list of the interfaces where the DHCP daemon listens
/etc/altq.conf - the file which contains the configuration of the alternate queueing daemon - class based queueing pachet scheduler
/etc/pf.conf - configuration file for packet filtering
/etc/nat.conf - NAT rules
