Dear Karthikeyan.N As I pointed out to you yesterday it will be a good idea to read the RIPE Database User Manual: Getting Started http://www.ripe.net/ripe/docs/db-start.html This clearly explains how to create objects in the RIPE Database and how to query for them. It was written to help new users to get started. The answer to your specific problem below is the '# Filtered' comment on the "source:" line. The update program will not accept updates with filtered query output. You may also want to check your database naming as you have used nic-hdls like AA1-TEST with a source of SAMPLE. Maybe these should both be either TEST or SAMPLE. -- Regards, Denis Walker RIPE Database Administration On Tue, 9 Jan 2007 10:44:19 +0530, Linux Baby wrote: * hi, * Can you give me one example for dbupdate command to * create/delete/update * objects using commandline/webinterface. * * regards * Karthikeyan.N
