RRCC scripts beta release
by DB-News 23 Jan '03

23 Jan '03

[apologies for duplicate messages] Dear Colleagues, We are happy to announce the beta release of RRCC scripts. Routing Registry Consistency Check, or RRCC project had already its web interface, where you can check the accuracy of your data in the RIPE Routing Registry and Whois Database. Per-maintainer reports are also available as in an e-mail interface. For more information, please visit http://www.ripe.net/rrcc/ . Now you can build you own RRCC database yourself, using RRCC scripts, which you can find at ftp://ftp.ripe.net/ripe/dbase/software/RRCC-0.2.tar.gz Using these scripts, you can check the consistency of other routing registries as well. Please contact rrcc(a)ripe.net for any comments. Best regards, Engin Gunduz RIPE NCC Database Group
