some system checks

The first thing I do when I take over a new system , is write a check script.
You can check several things and tailor it to your system, but here are a few to get you started:

check for users and groups that are equal with root

# grep ':00*:' /etc/passwd

check for invalid passwords
# grep invalid /usr/adm/syslog

list the last 20 logins

# last | head -20


#/usr/platform/sun4u (uname -n)/sbin/prtdiag -v

will show you useful hardware information.

#df -k -F ufs

will show you only local disks , and show you the total space used space, and free space


#/usr/sbin/psrinfo -v

will show you the cpus adn their speed.
