I saw some days ago someone asking about user authentication via
tcp_wrappers' hosts.allow file.I dont have original mail, but I tried
something here that worked out.
Here's the hint:
If you have identd running on the client machine, you may put something
like "username @
machine" in hosts.allow, and forbid everything
from that machine on hosts.deny, and then tcp wrappers will allow
connections from that machine *if* the user running the client is the one
Hope this helps.
