 wtmp file I've seen a bunch of posts about this file, but I just want to be sure anyway.. Is it safe for me to set up a cron job to truncate this file? ex: tail -500 wtmp > tmpfile mv tmpfile wtmp chmod 664 wtmp or do I have to do something special to it? I am on AIX 4.3.3 -- Posted via http://dbforums.com      |

| Re: wtmp file your method is not safe wtmp is not an ascii file you need to do the following: /usr/sbin/acct/fwtmp < /var/adm/wtmp > /tmp/tmpfile tail -500 /tmp/tmpfile > /tmp/tmpfile2 /usr/sbin/acct/fwtmp -ic < /tmp/tmpfile2 > /var/adm/wtmp rm /tmp/tmpfile rm /tmp/tmpfile2 make sure you have bos.acct installed to use the fwtmp command On Mon, 22 Sep 2003 10:25:05 -0400, sengstock3 <member25238@dbforums.com> wrote: > >I've seen a bunch of posts about this file, but I just want to be >sure anyway.. > > > >Is it safe for me to set up a cron job to truncate this file? > > > >ex: > > > >tail -500 wtmp > tmpfile > >mv tmpfile wtmp > >chmod 664 wtmp > > > > > >or do I have to do something special to it? > > > >I am on AIX 4.3.3 |
