Help

Hello ! I need help. I'm a student. A part of my summer practice is to setup a whois server ,under Fedore Core 4,running at port 43 . Mainly it's database ,should contain the registered domain names, creation date, expiration date, update date, "black list" and other related information. So far, I have compiled and installed RIPE Whois Server 3.3.0. It works very well with the SAMPLEDB. But I haven't seen such a field as expiration date. Usually in whois lookups I get such kind of information. I have to create it manually ? Or it is kept in other field ? Best regards, Nicolae
