Greetings to all SUN managers worlwide community!

Would you, please, help me with the followiong problem:

I found that several Solaris 2.6 servers have "strange" permissions set
for /dev/mem and /dev/kmem special files:

crw-r--r-- 1 root sys 13, 0 <PY 18 2000 /dev/mem
crw-r--r-- 1 root sys 13, 1 <PY 18 2000 /dev/kmem

I think that these special files must not be all readable, especially
on production servers. What do you think?

And the second important question:

I wonder is there any tool that could check all system
files for proper access rights and checksum? Perhaps the tool must
have its own database that can be updated in case if you apply a patch or
install a new version of software.

Look forward in your help,

Vitaly Beliaev
