I now would expect the server to reply with "no such > name", but it doesn't. the "o such name" also known asa NXDOMAIN reply means "dls-koe-v6.gvs.local does not exist". It's false, because it DOES exist, it just does not have A record. Apropriate response it NODATA that means "dls-koe-v6.gvs.local exists but does not have A recors". -- Matus UHLAR - fantomas, uhlar@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
