7
9 unbound-streamtcp [-unsh] [-f ipaddr[@port]] [-d secs] name type class
10
12 unbound-streamtcp sends a DNS Query of the given type and class for the
13 given name to the DNS server over TCP and displays the response.
14
15 If the server to query is not given using the -f option then localhost
16 (127.0.0.1) is used. More queries can be given on one commandline, they
17 are resolved in sequence.
18
19 The available options are:
20
21 name This name is resolved (looked up in the DNS).
22
23 type Specify the type of data to lookup.
24
25 class Specify the class to lookup for.
26
27 -u Use UDP instead of TCP. No retries are attempted.
28
29 -n Do not wait for the answer.
30
31 -s Use SSL.
32
33 -h Print program usage.
34
35 -f ipaddr[@port]
36 Specify the server to send the queries to. If not specified
37 localhost (127.0.0.1) is used.
38
39 -d secs
40 Delay after the connection before sending query. This tests the
41 timeout on the other side, eg. if shorter the connection is
42 closed.
