Good stuff. You may also need dynamic routing software or by hand enter your routing configuration. Start with "apropos routing; apropos route" to get a list of possible commands that you have already installed. Search the RedHat-9 documentation for routing info, setup and tips. Google search for Linux route and Linux routing for things. For many people all you need to do is: chkconfig routed on; service routed start or chkconfig zebra on; service zebra start Read the man pages for what ever routing agent you elect to use. Ip tables and other filter tricks need attention. The key is the "or". You want one and only one dynamic routing agent active in the system. This may include your fingers. For most of us there is a need to understand "RFC-1918" and what "private address spaces" are. By convention "private address spaces" are not routed. So if you are using any of these IP address ranges ( Examples: 10.0.0.0, 192.168.0.0, 192.168.1.0... or 172.16.--172.31.0.0) you will have to read the fine manuals (polite speak for RTFM) and configure things as needed. http://www.faqs.org/rfcs/rfc1918.html http://www.cis.ohio-state.edu/cgi-bin/rfc/rfc1918.html For today skip the IPV-6 tools and stuff ;-) $ (apropos routing; apropos route) | sort | uniq .... some edits .... bgpd (8) - a BGPv4, BGPv4+, BGPv4- routing engine for use with Zebra ip (8) - TCP/IP interface configuration and routing utility ipx_route (8) - add or delete IPX route NETLINK_ROUTE [rtnetlink] (7) - Linux IPv4 routing socket netstat (8) - Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships ospfd (8) - an OSPF v2 routing engine for use with Zebra radvd (8) - router advertisement daemon for IPv6 radvd.conf [radvd] (5) - configuration file of the router advertisement daemon radvd radvdump (8) - dump router advertisements rdisc (8) - network router discovery daemon ripd (8) - a RIP routing engine for use with Zebra ripngd (8) - a RIP routing engine for use with Zebra and IPv6 route (8) - show / manipulate the IP routing table routed (8) - network routing daemon rtnetlink (7) - Linux IPv4 routing socket traceroute (8) - print the route packets take to network host vtysh (1) - a integrated shell for Zebra routing software xtraceroute (1) - graphical (X11) traceroute zebra (8) - a routing manager for use with associated components -- T o m M i t c h e l l /dev/null the ultimate in secure storage.
