good morning list,
i installed auditd on my gentoo server.
installation runs without error, but on start i get this:
# /etc/init.d/auditd start
* Starting auditd ...
[ ok ]
touch: cannot touch '/var/lock/subsys/auditd': No such file or directory
* Loading audit rules from /etc/audit/audit.rules
seems /var/lock/ `subsys/auditd` is missing.
that was easy to fix, but has to be repeated after every reboot.
in auditd.log i get entries like this:
type=NETFILTER_CFG msg=audit(1412022284.553:2446): table=mangle family=2
entries=6
type=SYSCALL msg=audit(1412022284.553:2446): arch=c000003e syscall=54
success=yes exit=0 a0=4 a1=0 a2=40 a3=1144850 items=0 ppid=2070 pid=2130
auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0
tty=(none) ses=4294967295 comm="iptables" exe="/sbin/xtables-multi"
key=(null)
i want to suppress these messages.
in my understanding of the man page i have to put such a rule into
audit.rules:
-a exclude,never -F msgtype=NETFILTER_CFG , but this isnt working. the
messages still appears.
my config of my fresh auditd install:
# First rule - delete all
# This is to clear out old rules, so we don't append to them.
-D
# Feel free to add below this line. See auditctl man page
-a exclude,never -F msgtype=NETFILTER_CFG
# The following rule would cause all of the syscalls listed to be
ignored in logging.
-a exit,never -F arch=b32 -S read -S write -S open -S fstat -S mmap -S
brk -S munmap -S nanosleep -S fcntl -S close -S dup2 -S rt_sigaction -S
stat
-a exit,never -F arch=b64 -S read -S write -S open -S fstat -S mmap -S
brk -S munmap -S nanosleep -S fcntl -S close -S dup2 -S rt_sigaction -S
stat
-a exclude,never -F msgtype=NETFILTER_CFG
# The following rule would cause the capture of all systems not caught
above.
# -a exit,always -S all
# Increase the buffers to survive stress events
-b 8192
# lock the audit configuration to prevent any modification of this file.
-e 2
i installed audit 2.2.2-r2 on gentoo if this is of intzerest.
thank you
marko
