Hi, I've just seen that the function checkdnsrr return always true on my server whereas on my laptop with Apache2 the function works perfectly. This bug is seen also on the dedicated server of a friend, debian stable with the same PHP version and apache 1.3 Because I don't know in wha paquet there is the bug, I send thisbug report to the php4's mainteners and the Apache's mainteners. P.S sorry for my english who is very bad.
