24 | .TH NSS-ICMP.CONF 5 "12 Jan 2006" "icmpdn 0.3" "ICMP Hostname Manual" |
25 | .SH NAME |
26 | nss-icmp.conf - Configuration file for the nss-icmp nameswitch module |
27 | .SH DESCRIPTION |
28 | \fB/etc/nss-icmp.conf\fP is an ASCII file which controls certain |
29 | operating parameters for the \fBnss-icmp\fP(7) nameswitch module. Each |
30 | line in the file takes the form of a key-value pair, seperated by |
31 | whitespace. Some keys may not have a value. Lines beginning with a |
32 | hash sign (#) are interpreted as comments, and thus ignored. |
33 | .P |
34 | Valid entries are: |
35 | .TP |
36 | \fBtimeout\fP \fImilliseconds\fP |
37 | Instructs \fBnss-icmp\fP to pass the -t option to \fBidnlookup\fP(1), |
38 | which changes the default time-out for nonresponsive hosts to the |
39 | specified number of milliseconds. |
40 | .TP |
41 | \fBttlnotfount\fP \fIseconds\fP |
42 | Specifies the TTL (Time-to-Live) value to use when caching a |
43 | non-responsive host. In other word, if a host is found to be |
44 | non-responsive (i.e. times out), the same address will not retried |
45 | again until the specified time has passed, as to prevent annoying |
46 | time-outs. |
47 | .TP |
48 | \fBnocache\fP |
49 | If this directive is present, \fBnss-icmp\fP will not use its |
50 | cache. Since this makes reverse hostname lookups slower, especially in |
51 | the case of non-responsive hosts, the use of this directive is |
52 | generally not recommended, but may be useful in certain debugging |
53 | situtations. |
