I am using redhat 6, and trying to create logs for some system call using the rule given below: *-a always,exit -F arch=b64 -S chmod -S fchmod -S fchmodat -F auid>=500 -F auid!=4294967295 -k perm_mod*

After running command chmod i was not able to get any log, but when i used strace command i have seen that syscall have been called. I also checked that auditd service is running properly.

when i am using auid>=500 in quote like u have told -a always,exit -F arch=b64 -S chmod -S fchmod -S fchmodat -F 'auid>=500' -F auid!=4294967295 -k perm_mod it is giving error : #service auditd restart Stopping auditd: [ OK ] Starting auditd: [ OK ] -F unknown field: "auid There was an error in line 102 of /etc/audit/audit.rules On Sat, Jan 14, 2012 at 1:34 AM, Steve Grubb <sgrubb(a)redhat.com <mailto:sgrubb@redhat.com>> wrote: On Thursday, January 12, 2012 11:52:29 PM bharat gupta wrote: > I am using redhat 6, and trying to create logs for some system call using > the rule given below: > > *-a always,exit -F arch=b64 -S chmod -S fchmod -S fchmodat -F auid>=500 > -F auid!=4294967295 -k perm_mod* The rule works for me. # auditctl -a always,exit -F arch=b64 -S chmod -S fchmod -S fchmodat -F 'auid>=500' -F auid!=4294967295 -k perm_mod I don't have any asterisk and I have single quote marks since bash will interpret the > as a redirection. But then doing a chmod command, it does pick up the fchmodat() syscall. > After running command chmod i was not able to get any log, but when i used > strace command i have seen that syscall have been called. > I also checked that auditd service is running properly. When you use auditctl -l, is the rule just like you expected? LIST_RULES: exit,always arch=3221225534 (0xc000003e) auid>=500 (0x1f4) auid!=-1 (0xffffffff) key=perm_mod syscall=chmod,fchmod,fchmodat It should just work unless you are on a distribution that does not really support auditing. -Steve -- Bharat Gupta IIT -Roorkee -- Linux-audit mailing list Linux-audit(a)redhat.com https://www.redhat.com/mailman/listinfo/linux-audit
