6 unbound-streamtcp - unbound DNS lookup utility
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 -a Print answers on arrival. This mean queries are sent in se‐
32 quence without waiting for answer but if answers arrive in this
33 time they are printed out. After sending queries the program
34 waits and prints the remainder.
35
36 -s Use SSL.
37
38 -h Print program usage.
39
40 -f ipaddr[@port]
41 Specify the server to send the queries to. If not specified lo‐
42 calhost (127.0.0.1) is used.
43
44 -d secs
45 Delay after the connection before sending query. This tests the
46 timeout on the other side, eg. if shorter the connection is
47 closed.
48
49 -p client
50 Use proxy protocol to send the query. Specify the ipaddr@portnr
51 of the client to include in PROXYv2.
52
53 IXFR=serial
54 Pass the type of the query as IXFR=N to send an IXFR query with
55 serial N.
56
57 NOTIFY[=serial]
58 Pass the type of the query as NOTIFY[=N] to send a notify
59 packet. The serial N of the new zone can be included.

64 $ unbound-streamtcp www.example.com A IN
65
66 $ unbound-streamtcp -f 192.168.1.1 www.example.com SOA IN
67
68 $ unbound-streamtcp -f 192.168.1.1@1234 153.1.168.192.in-addr.arpa. PTR
