Not really - you can do the last command to find out who was / is logged in, but that won't be on one central server. If you push your syslog entries out to a central server, you can add an entry into different profiles (/etc/profile and if you use a central user profile) allowing the logger command to note that someone logged in.
Example:
Add to /etc/profile:
/bin/logger "`/bin/logname` logged into `/bin/hostname`"
That would add an entry such as this to /var/adm/messages (if syslog.conf is set up for it)
Aug 8 10:39:50 toast operator: [ID 702911 user.notice] operator logged into toast
Entry in syslog.conf:
*.emerg;*.err;*.alert;*.crit;*.warning;*.notice;*.debug @syslog1.mycom.com
This would log telnet sessions (but not ssh or rsh). Adding the same logger command to each user's .profile (or a central profile - can be done if all users have nfs mounted home directories, don't need (or security disallows) users changing .profile) will log messages if using ssh or rlogin commands (not when copying files with scp or running a command along with a rsh).
(Seems like too much work to bother, but it would give you what you a decent logging method).

arithmetic
ARITHMETIC(6) Games Manual ARITHMETIC(6)
NAME
arithmetic - provide drill in number facts
SYNOPSIS
/usr/games/arithmetic [ +-x/ ] [ range ]
DESCRIPTION
Arithmetic types out simple arithmetic problems, and waits for an answer to be typed in. If the answer is correct, it types back "Right!",
and a new problem. If the answer is wrong, it replies "What?", and waits for another answer. Every twenty problems, it publishes statis-
tics on correctness and the time required to answer.
To quit the program, type an interrupt (delete).
The first optional argument determines the kind of problem to be generated; +-x/ respectively cause addition, subtraction, multiplication,
and division problems to be generated. One or more characters can be given; if more than one is given, the different types of problems
will be mixed in random order; default is +-
Range is a decimal number; all addends, subtrahends, differences, multiplicands, divisors, and quotients will be less than or equal to the
value of range. Default range is 10.
At the start, all numbers less than or equal to range are equally likely to appear. If the respondent makes a mistake, the numbers in the
problem which was missed become more likely to reappear.
As a matter of educational philosophy, the program will not give correct answers, since the learner should, in principle, be able to calcu-
late them. Thus the program is intended to provide drill for someone just past the first learning stage, not to teach number facts de
novo. For almost all users, the relevant statistic should be time per problem, not percent correct.
