Operating Systems Solaris uptime command not showing how long the system has been up Post 302493347 by rbatte1 on Wednesday 2nd of February 2011 12:17:53 PM

I'm not sure you can simply overwrite /var/adm/utmpx in this way. I had an odd problems with /etc/security/failedlogin (on AIX) a while back and had to recreate the file as follows:-
Code:
fwtmp -ic </dev/null >/etc/security/failedlogin

Unfortunately, this resets everything to blank.



The other way is to look at process zero or process one. They start with the operating system, indeed if you kill them, everything on the machine goes very quiet and the phone rings..... as I found out one day.

NAME
utmpx, wtmpx - utmpx and wtmpx database entry formats SYNOPSIS
#include <utmpx.h> /var/adm/utmpx /var/adm/wtmpx DESCRIPTION
The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files. The utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database contains the history of user access and accounting information for the utmpx database. USAGE
Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to inter- act with the utmpx and wtmpx databases to ensure that they are maintained consistently. FILES
/var/adm/utmpx user access and adminstration information /var/adm/wtmpx history of user access and adminstrative information SEE ALSO
