Hi,

I am unsuccessfully trying to get the ruletype method to work as
follows:

ruletype auditlog
{
type alert
output alert_syslog: LOG_AUTH LOG_INFO
output log_null
}

auditlog icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"ICMP PING *NIX";
itype:8; content:"|10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F|";
depth:32;)

I have disabled the corresponding alert rule in the icmp-info.rules
file. If I reenable the rule in the icmp-info.rules file it is picked
up as an alert (as expected). If I disable in icmp-info.rules and
enable in local.rules no log is generated.

Is this a bug, as I cannot make any of the output plugins work within
ruletype.

Regards,
Don
