RH 4.2 uses libc 5, RH 5.x (and future versions) use glibc. glibc has a
different format for those files than libc 5 did. I would imagine that you
could simply "null" (cp /dev/null <file>) the files utmp and wtmp (and
probably lastlog as well).

If you then re-login, things should work.

1. utmp/wtmp problem (RH5.0)

Hi! I'm pretty sure that this issue has been thoroughly discussed in
past but I couldn't find any articles in RedHat's 'hurrican-list' archive
regarding it. So I'll appreciate if anyone of you could please point
me out in the right direction.

Well here's the problem. Everytime someone telnets/rlogins in my
machine, wtmp gets all messed up:

t ttyp6 p6 Wed Dec 31 18:00 still logged in
*T ** Wed Dec 31 18:00 still logged in
*T ** Wed Dec 31 18:00 - 18:00 (00:00)
*T ** Wed Dec 31 18:00 - 18:00 (00:00)
*T ** Wed Dec 31 18:00 - 18:00 (00:00)
*T ** Wed Dec 31 18:00 - 18:00 (00:00)
...

wtmp begins Wed Apr 29 02:42:35 1998

Moreover, doing a "finger" or "w" does not show that they're logged in.
"xterm", however, does create correct entries in wtmp and utmp. If I
go in X, and fire up an xterm, it does show that I'm logged in, doing a
"last" also shows the correct entry.

And for some odd reason, everytime I 'touch' a file, it sets the time
5 hours ahead.:
