昨天我在樹莓派上設定了一個 isc dhcp 伺服器和一個 dns 綁定伺服器。
現在的問題是，dhcp 伺服器不會將 dns 伺服器分發給用戶端，但如果我在 Windows 電腦設定中手動指定本機 dns 伺服器，則一切正常。順便說一句，我的所有客戶端都從 dhcp 伺服器取得 IPv4 位址。
我的 dhcp 伺服器配置/etc/dhcp/dhcpd.conf：：
#
# Sample configuration file for ISC dhcpd for Debian
#
#
# The ddns-updates-style parameter controls whether or not the server will
# attempt to do a DNS update when a lease is confirmed. We default to the
# behavior of the version 2 packages ('none', since DHCP v2 didn't
# have support for DDNS.)
ddns-updates on;
ddns-update-style interim;
ddns-domainname "mydomain.home";
ddns-rev-domainname "0.1.10.in-addr.arpa";
ignore client-updates;
# If you have fixed-address entries you want to use dynamic dns
update-static-leases on;
# option definitions common to all supported networks...
option domain-name "mydomain.home";
option domain-name-servers 10.1.0.2;
option ntp-servers 0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org, 3.pool.ntp.org;
default-lease-time 600;
max-lease-time 7200;
ping-check true;
ping-timeout 2;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
key dhcpupdate {
algorithm hmac-md5;
secret MYSUPERSECRET==;
}
zone naef.home {
primary 127.0.0.1;
key dhcpupdate;
}
zone 0.1.10.in-addr.arpa {
primary 127.0.0.1;
key dhcpupdate;
}
# This is a very basic subnet declaration.
subnet 10.1.0.0 netmask 255.255.255.0 {
range 10.1.0.50 10.1.0.254;
option routers 10.1.0.1;
option broadcast-address 10.1.0.255;
}
# Hosts which require special configuration options can be listed in
# host statements. If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.
#host passacaglia {
# hardware ethernet 0:0:c0:5d:bd:95;
# filename "vmunix.passacaglia";
# server-name "toccata.fugue.com";
#}
# Fixed IP addresses can also be specified for hosts. These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP. Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
#host fantasia {
# hardware ethernet 08:00:07:26:c0:a5;
# fixed-address fantasia.fugue.com;
#}
# You can declare a class of clients and then do address allocation
# based on that. The example below shows a case where all clients
# in a certain class get addresses on the 10.17.224/24 subnet, and all
# other clients get addresses on the 10.0.29/24 subnet.
#class "foo" {
# match if substring (option vendor-class-identifier, 0, 4) = "SUNW";
#}
#shared-network 224-29 {
# subnet 10.17.224.0 netmask 255.255.255.0 {
# option routers rtr-224.example.org;
# }
# subnet 10.0.29.0 netmask 255.255.255.0 {
# option routers rtr-29.example.org;
# }
# pool {
# allow members of "foo";
# range 10.17.224.10 10.17.224.250;
# }
# pool {
# deny members of "foo";
# range 10.0.29.10 10.0.29.230;
# }
#}

好的。知道了。我的提供者重新啟用了我的路由器的 dhcp 服務。禁用後一切正常！
