-
By default, finger @wassamatta.edu will yield
names of all users who are logged in
-
fingerd -s option prevents listing of all
users who are logged in
-
-p option sends output of a program other than finger
in response to net queries. We use nonetfinger.c:
#include <stdio.h>
main() {
puts("Sorry; for security
reasons, and to prevent our users");
puts("from being targeted
for unsolicited \"junk\" e-mail, this");
puts("site does not honor
network finger requests. We apologize");
puts("for any inconvenience.");
