[comp.protocols.tcp-ip] RARP implimentations for BSD 4.3 tahoe/reno

jclark@sdcc6.ucsd.edu (John Clark) (03/04/91)

The standard BSD 4.3 does not seem to have a 'rarpd' program
implimented. Is there a public version of the RARP protocol.

We use bootpd for ip address resolution for ethernetted PCs on a tahoe
running BSD 4.3, but Macs running NCSA Telnet look for rarpd to 
dynamically get an ip number.  Apparently there isn't an rarpd implementation
under BSD for security reasons - it doesn't like user level processes looking
at ethernet packets.  If someone has discovered a workaround for this, other
than assigning ip numbers for the Macs manually, I'd like to hear it.

The solution...

If you use MacTCP, the "server" mode first looks for Fastpath-like devices
configured to hand out dynamic addresses, then looks for a Rarp server, then
looks for a bootp server.  This works as of version 1.01.

Thanks to those who replied, and in particular to Dan for the above.
