There's no mechanism in HP-UX to rotate /var/adm/wtmp or /var/adm/btmp. You can set up a cron job to rotate them periodically. Or use a tool like logrotate that you can get from the Porting Center to manage them and many other log files HP-UX doesn't manage out-of-the-box. A quick and dirty rotation:

cp -p /var/adm/wtmp /var/adm/wtmp.old
> /var/adm/wtmp
gzip /var/adm/wtmp.old

Hi:

The file 'var/adm/wtmp' and its cousin '/var/adm/btmp' for logging successful and unsuccessful logins, respectively, grown without bounds.

If you don't want to log the activity, remove the file. That disables the logging.

Otherwise you can null the file:

# cat /dev/null > /var/adm/wtmp

...or trim it by first converting the binary data to ASCII; trimming what you don't want; and then converting the ASCII version back to the binary form:

# # /usr/sbin/acct/fwtmp < /var/adm/wtmp > /tmp/wtmp

[ trim the ASCII file as necessary ]

# /usr/sbin/acct/fwtmp -ic < /tmp/wtmp > /var/adm/wtmp

Regards!

Shalom indrajit,

Once a week, I have a script that does this:

cp /var/adm/syslog/wtmp /copytotape
cp /var/adm/syslog/btmp /copytotape

> /var/adm/syslog/wtmp
> /var/adm/syslog/btmp
