Sorry, I' m not a developer. I'm trying to find a solution from an administrator's point of view. How about doing something like: on log attr <attrname> notify <[ip]:[port]> which would send a "message" with the attr name, the old and the new value of the attribute to [ip]:[port]. Then, someone can set up a net listening process like netcat (nc) to read data and do whatever. Nick On 7/10/2010 5:32 πμ, Howard Chu wrote:
