So far, the effect here is that tcpd rejects | connections from systems with 'allowed' domain names. | | DNS-aware tools such as 'nslookup' and 'dig' are just fine. | | I believe this has to be fixed before | draft-ietf-cidrd-classless-inaddr-01.txt becomes a standard. This *is* fixed in 4.9.3-REL. Actually it was fixed earlier than that (4.9.3-BETA26 or thereabouts). Upgrade your software. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
