- This ethernet access library is a part of the Columbia Netmate project which is
- being released as a useful component in its own right.
-
- These functions provide access to the raw ethernet for user-level programs. On
- Suns, they are implemented using NIT(4p) (network interface tap). While they
- do not provide the full functionality of NIT, these functions do run on both
- the socket- and streams-based NIT implementations. On Ultrix systems, they are
- implemented using DLI (data link interface). On Berkeley systems, they are
- implemented using the Stanford enetfilter available as user-contributed
- software in the 4.3 BSD release.
-
- These functions are not designed to be used for ethernet monitoring, but rather
- for programs implementing ethernet protocols such as RARP, or the Ethernet
- configuration test protocol.
-
- It comes with a manual page, and both a GNU makefile and a regular one.
-
- If you are on a BSD system with the enetfilter, you will have to create some
- new device files before you can build or use this library. Because there is no
- way to map between the interface names ("il0", "de0", etc.) used by most
- programs and the old enetfilter device names (/dev/enet0, /dev/eneta0, etc.),
- this library uses a different convention for enetfilter device names, using
- device files in the /dev/enet/ directory.
-
- Therefore, you should create or link an enetfilter device in /dev/enet for each
- ethernet interface, with names like /dev/enet/il0, /dev/enet/de0, etc. The
- minor device numbers for these files will correspond to the order in which they
- are found by the kernel. This order is the same as in the config file, except
- that devices configured into the kernel but not present are not counted. You
- can look at the kernel startup messages in /usr/adm/messages to see the order
- of ethernet devices; the ethernet addresses are also printed out there, and you
- can check those against the results of the ethertest program here.
-
- If you have GNU make, you should be able to say "gmake" in this directory, and
- it will build the library for your system in a subdirectory. You may want to
- edit the GNUmake.config file to specify various options (such as installation
- directories, cc vs. gcc, etc.) Once you are satisfied that it has built
- correctly, you can say "gmake install".
-
- If you don't have GNU make, you will have to cd to the src subdirectory, and
- edit the Makefile there to reflect your system configuration. Once you have
- done this, you can say "make" to build the library, and "make install" to
- install it.
-
- If you encounter bugs, or are interested in porting this library to another
- ethernet access interface, please contact me.
