25 | .SH NAME |
26 | icmpdnd - ICMP domain name responder |
27 | .SH SYNOPSIS |
28 | .B icmpdnd |
29 | [ \fB-nh\fP ] [ \fB-t\fP \fIttl\fP ] [ \fB-d\fP \fIdomainname\fP ] |
30 | .SH DESCRIPTION |
31 | \fBicmpdnd\fP is daemon that answers ICMP host name requests. It is |
32 | capable of handling requests over both IPv4 and IPv6. |
33 | .P |
34 | When called without arguments, \fBicmpdnd\fP will answer requests with |
35 | the host name that is specified in the operating system through the |
36 | \fBsethostname\fP(2) and \fBsetdomainname\fP(2) calls. On GNU/Linux, |
37 | these are normally called by the \fBhostname\fP(1) program. |
38 | .SH OPTIONS |
39 | .TP |
40 | .B -h |
41 | Print a brief usage message and exit. |
42 | .TP |
43 | .B -n |
44 | Do not daemonize, but continue to run on the calling terminal. |
45 | .TP |
46 | .B -t |
47 | Set the TTL (Time-to-Live) value in responses to \fIttl\fP seconds, |
48 | rather than the default of 3600 seconds. |
49 | .TP |
50 | .B -d |
51 | Set the domain name in responses to \fIdomainname\fP, rather than the |
52 | default as described above. This option is useful in case the system |
53 | is not configured to set up its own hostname. |
