Help: problems with 'w', 'who' and 'last'

Help: problems with 'w', 'who' and 'last'

Post by Ted Sariysk » Thu, 31 Dec 1998 04:00:00

Recently I upgraded our machines from RedHat5.1 to
RedHat5.2. Everything is OK, but now three machines behave
strange with w, who and last. last returns trash:

still logged in
p1       21.pv.reshsg                  Wed Dec 31 16:00 -
16:00  (00:00)
dialin33 p1                            Wed Dec 31 16:00 -
16:00  (00:00)

w and who give only the top line and empty body:

 10:03am  up 7 days, 19:52,  0 users,  load average: 0.00,
0.00, 0.00


I copied these executables from machines where they behave
well along with /var/log/wtmp file and for a while this
fixed the problem, but after a couple of minutes the problem
appeared again. It seems that there is a reference data set
that is updated periodically ... I really have no idea what
is going on.

Is there an easier way to fix this problem than reinstalling
the OS?

Thanks. Ted


1. Help:How to use 'router','mailq','zmailer' etc?

Hi.  My school doesn't offer slip/ppp connection, so I'm force
to use a program call 'slirp' to emulate ppp.  One good thing about
slirp is that it can execute a program and route it to a particular port
of your choice.  For example, I can get slirp to execute 'smtpserver -n'
and redir it to port 25, so I can send out e-mail this way.  I would
like to retrieve email to my home computer also.  I hope by learning how
to use the 'router', 'mailq', and 'zmailer' command, I can do it.  Can
someone please tell me how?  I assume that I have to start one of the
program and then redir it to port 110.  Please help.
