when i do rpm --verify -a it verifyes every packages in my system, but i do get som failure codes...like this

[root@firewall root]# rpm --verify -a
S.5....T c /etc/pam.d/system-auth
.......T c /etc/libuser.conf
SM5....T /usr/lib/perl5/5.8.1/i386-linux-thread-multi/CORE/libperl.so
S.5....T c /etc/ldap.conf
S.5....T c /etc/sysconfig/rhn/up2date-uuid
.......T c /etc/krb5.conf
.M...... /dev/shm
.M....G. /dev/tty3
.M....G. /dev/tty4
.M....G. /dev/tty5
.M....G. /dev/tty6
S.5....T c /etc/openldap/ldap.conf
S.5....T c /etc/yp.conf
S.5....T c /etc/snort/snort.conf
.M...... /var/log/snort
.M...... /dev/shm
S.5....T c /etc/krb.conf
.......T c /etc/pam_smb.conf
S.5....T c /etc/sysconfig/pcmcia
.M...... /dev/shm

is there something wrong with the files, like if there is a rootkit or something, i have tested with for rootkits, but no rootkits installed..

"man rpm" explains the verification status flags. It's expected that modified configuration files or changed device file ownerships are listed in the output. But only you can verify the output yourself and tell whether it's correct.
