That's interesting. When I do this sequence with the .22 kernel and the 1.2.1 tools: # auditctl -a entry,always -S all -F pid=1005 # auditctl -a entry,always -S all -F pid=1005 Error sending add rule request (File exists) I get these records: type=CONFIG_CHANGE msg=audit(1148054817.056:575): auid=500 subj=user_u:system_r:auditctl_t:s0-s0:c0.c255 add rule to list=2 res=1 type=CONFIG_CHANGE msg=audit(1148054831.417:576): auid=500 subj=user_u:system_r:auditctl_t:s0-s0:c0.c255 add rule to list=2 res=0 I believe res=1 means the operation was successful and the res=0 means it failed. Are you sure one of your records doesn't have res=1? I don't know what the "add rule to list=2" means though. What is the exact rule you're adding? And which kernel/tools are you running? BTW, with RHEL4U2 we only got a record on the success case. type=CONFIG_CHANGE msg=audit(1148054734.395:10530): auid=500 added an audit rule -- ljk
