Simultaneous support

You can run both io-net and io-pkt simultaneously on the same target if the relevant utilities and daemons for each stack are present.

Here are some specific issues you should be aware of:

• The socket library is backward-compatible with all BSD socket API applications. This also extends to the routing socket.
• Applications with a tight coupling to the TCP/IP stack, including ifconfig, netstat, arp, route, sysctl, inetd, pppd, and pppoed, aren't backward-compatible. Stack-specific versions need to be maintained and executed.
• Socket library and headers aren't saved. The new versions are backward-compatible.
• The following components may be compatible with io-pkt:
  • We've updated nicinfo to work with native io-pkt drivers (e.g. nicinfo wm0). NetBSD drivers don't operate with nicinfo.
  • You can run both io-net and io-pkt simultaneously, but you have to provide different instance numbers and prefixes to the stack. For example:

    io-pkt -d pcnet pci=0 
    io-net -i1 -dpcnet pci=1 -ptcpip prefix=/alt
      

    Note that the io-net versions of the utilities must be present on the target (assumed, for this example, to have been placed in a separate directory) and run with the io-net stack. For example:

    SOCK=/alt /io-net/ifconfig en0 192.168.1.2
    SOCK=/alt /io-net/inetd
