| 5 | .B /etc/resolv.conf

|
|---|
| 11 | The
|
|---|
| 12 | .B /etc/resolv.conf
|
|---|
| 13 | is used to configure how the host will use the Domain Name System to resolve
|
|---|
| 14 | hostnames to IP addresses. It may contain these two lines:
|
|---|
| 15 | .PP
|
|---|
| 16 | .RS
|
|---|
| 17 | .ta +15n
|
|---|
| 18 | nameserver \fIIP-address\fP
|
|---|
| 19 | .br
|
|---|
| 20 | domain \fIdomain-name\fP
|
|---|
| 21 | .RE
|
|---|
| 22 | .PP
|
|---|
| 23 | The nameserver entry tells the IP address of the host to use for DNS
|
|---|
| 24 | queries. If it is set to 127.0.0.1 (which is the default) then the local
|
|---|
| 25 | name daemon is used that may use the
|
|---|
| 26 | .B /etc/hosts
|
|---|
| 27 | database to translate host names. You normally only need a nameserver entry
|
|---|
| 28 | if the name server is at the other side of a router. The default
|
|---|
| 29 | .B nonamed
|
|---|
| 30 | name server can't look beyond the local network.
|
|---|
| 31 | .PP
|
|---|
| 32 | The domain entry tells the default domain to use for unqualified hostnames.
|
|---|
| 33 | This entry is usually not given in which case the domain of the local host
|
|---|
| 34 | is used.
|
