不正確的子網/遮罩組合
對於網路介面,我為 DHCP 定義了一個地址範圍。
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 08:00:27:5a:3e:be brd ff:ff:ff:ff:ff:ff inet 10.0.2.1/24 brd 10.0.2.255 scope global eth1
並且 dhcpd.conf 文件包含
subnet 10.0.2.1 netmask 255.255.255.240 { range 10.0.2.2 10.0.2.10; allow booting; allow bootp; class "pxeclients" { match if substring(option vendor-class-identifier, 0, 9) = "PXEClient"; next-server 10.0.2.3; filename "pxelinux.0"; } }
但是,當我啟動 dhcpd 時,出現此錯誤
/etc/dhcp/dhcpd.conf line 1: subnet 10.0.2.1 netmask 255.255.255.240: bad subnet number/mask combination. subnet 10.0.2.1 netmask 255.255.255.240 ^ Configuration file errors encountered -- exiting
問題是什麼?
您提供了子網內部的 IP 地址,而不是子網本身的地址。替換
subnet 10.0.2.1
為subnet 10.0.2.0
,它應該可以工作。
