Hi folks, Anyone have some experience using routerOS API? I've been extending the configuration group functionality of our DuxTel Commander, and come up against a challenge in filtering API query (http://wiki.mikrotik.com/wiki/API#Queries) The deal is that I use 'comment' field as a way to cross-reference router configuration entries with the configuration database items. For example, a firewall rule might look like: ip firewall filter add chain=forward src-address-list=blocked action=drop comment='Managed by DuxAdmin SetID:443 ItemID:27' So when I want to find all the firewall rules with SetID:443, I can do this: /ip/firewall/filter/find ?>comment=Managed by DuxAdmin SetID:443 Which seems to work OK, but I can't work out how to return just those entries that include 'ItemID:27' I'll put the question to MT support and post a solution (if there is one) if/when they respond, but if anyone has some suggestions, I'm 'all ears'! ;-) Cheers, Mike.
