The code is copyrighted by Sun, not some particular employee, so AFAICT 
digging up who wrote it will not be necessary.

For portmap:

 - from_local.c:

  * Check if an address belongs to the local system. Adapted from:
  * pmap_svc.c 1.32 91/03/11 Copyright 1984,1990 Sun Microsystems, Inc.
  * get_myaddress.c  2.1 88/07/29 4.0 RPCSRC.

 - portmap.c

 @(#)portmap.c   2.3 88/08/11 4.0 RPCSRC
 static char sccsid[] = "@(#)portmap.c 1.32 87/08/06 Copyr 1984 Sun

This is portmap-6.0, from http://neil.brown.name/portmap/

For glibc, it is basically everything in glibc/sunrpc, which got taken
from rpcsrc-4.0 according to the top-level LICENSING file:

"The Sun RPC support (from rpcsrc-4.0) is covered by the following
license: [...]"

The trunk code can be viewed at
http://sourceware.org/cgi-bin/cvsweb.cgi/libc/sunrpc/?cvsroot=glibc but
it would be desirable if Sun would relicense the past versions as well,
as Lenny will ship with glibc-2.7.  The tarballs can be found at

Hope that help,
