Well, you can if the remote host has an RFC 931 server. If you want to
set up an RFC 931 server under BSD, get pub/hier/inet/rfc931/authd.3.01
from stealth.acf.nyu.edu. Other files in the same directory include
patches to talk, sendmail, and nntpd to understand usernames provided by
the server. More applications (including the old version of authd, which
you shouldn't bother with) appear in the auth and authutil packages from
comp.sources.unix volume 22.
