NAME

unbound-streamtcp - unbound DNS lookup utility  

SYNOPSIS

unbound-streamtcp [-unsh] [-f ipaddr[@port]] [-d secs] name type class  

DESCRIPTION

unbound-streamtcp sends a DNS Query of the given type and class for the given name to the DNS server over TCP and displays the response.

If the server to query is not given using the -f option then localhost (127.0.0.1) is used. More queries can be given on one commandline, they are resolved in sequence.

The available options are:

name
This name is resolved (looked up in the DNS).
type
Specify the type of data to lookup.
class
Specify the class to lookup for.
-u
Use UDP instead of TCP. No retries are attempted.
-n
Do not wait for the answer.
-a
Print answers on arrival. This mean queries are sent in sequence without waiting for answer but if answers arrive in this time they are printed out. After sending queries the program waits and prints the remainder.
-s
Use SSL.
-h
Print program usage.
-f ipaddr[@port]
Specify the server to send the queries to. If not specified localhost (127.0.0.1) is used.
-d secs
Delay after the connection before sending query. This tests the timeout on the other side, eg. if shorter the connection is closed.
