-
- I'm afraid that you are all missing the point (except daveb, he's just being
- a little cruel)
-
- tcp_wrappers is a helpful package to install. It will tell you of this stuff,
- even if the other side is not running rfc931.
-
- Let us be more precise.
-
- Here is a log message from tcp_wrappers on a telnet session from a site that
- does not run rfc931:
-
- Aug 17 19:14:03 baire.math.psu.edu in.telnetd[2383]: connect from a5.ima.umn.edu
-
- And here is "better;" the same tcp_wrappers in effect and a log message
- coming in from a rfc931 site:
-
- Aug 15 21:13:24 lagrange.math.psu.edu in.rlogind[1296]: connect from grio@postscript.cs.psu.edu
-
- This, of course, works for finger as well.
-
- Without loss of generality, one can assume the other side does not have to
- be running rfc931 to get useful information on what is happening to your
- machine tcp/ip-wise. However, Tracy's original problem is solved precisely
- when the other site is running rfc931 code. Assuming that the other side is
- not running rfc931, however, one must take it into consideration that you can
- get no difference in an answer for you would get with tcp_wrappers with _or_
- without rfc931 support in place or _any other package_; one gets the site
- name only.
-
- rfc931 is a Good Thing, by the way.

- By the way, I've also been hacking on GNU finger. I'm glad to see that I'm
- not the only one who thinks that fingering ".help" is a pretty good idea.
