NSLOOKUP

NSLOOKUP (1)

DIAGNOSTICS

Exit status is zero for normal termination, a positive number for error termination. The diagnostic messages displayed for an unsuccessful search are:

Time-out

The server did not respond to a request after a certain amount of time (changed with set timeout=x) and a certain number of retries (changed with set retry=x).

No information

Depending on the query type set with the set query command, no information about the host was available, though the host name is valid.

Nonexistent domain

The host or domain name does not exist.

Connection refused Network is unreachable

The connection to the name or finger server could not be made at the current time. This error commonly occurs with finger requests.

Server failure

The name server found an internal inconsistency in its database and could not return a valid answer.

Refused

The name server refused to service the request.

Format error

The name server found that the request packet was not in the proper for- mat. NOTE: This error indicates that there is a bug in the program.

NOTES

If you are connected to a name server that handles more than one domain, all host names used in requests must be fully qualified by their domain. For example, the server seismo.css.gov handles three domains: harvard.edu, css.gov, and cornell.edu. A request for the host aiken in the domain harvard.edu must be specified as aiken.harvard.edu. The set domain=name and set defname commands can be used to automatically append a domain name to each request.
