Isc-Dhcpserver静态DHCP缺less客户端主机名

我的isc-dhcpserver（Ubuntu 16.04）出现了一个奇怪的问题。

当客户端从服务器请求时，我可以在/ var / log / syslog中看到以下输出：

Jun 21 21:41:25 drake dhcpd[265]: DHCPREQUEST for 192.168.0.113 (192.168.0.254) from ea:25:63:d9:6c:10 (webdev) via eth1 Jun 21 21:41:25 drake dhcpd[265]: DHCPACK on 192.168.0.113 to ea:25:63:d9:6c:10 (webdev) via eth1 

/var/lib/dh​​cp/dhcpd.leases对于这个租约看起来像这样：

 lease 192.168.0.113 { starts 3 2017/06/21 19:41:25; ends 4 2017/06/22 01:41:25; cltt 3 2017/06/21 19:41:25; binding state active; next binding state free; rewind binding state free; hardware ethernet ea:25:63:d9:6c:10; client-hostname "webdev"; 

现在让我们修改这个静态的DHCP：/etc/dhcp/dhcpd.conf：

• 文件服务器 – 主机名与FQDN
• 将服务部署到IIS时使用主机名与服务器名的优点/缺点？
• 在现有的MySQL服务器上更改主机名是否有任何问题？
• 将主机名称推送到没有DHCP的DNS服务器
• 内部networking主机名的名称parsing

 host webdev { hardware ethernet ea:25:63:d9:6c:10; fixed-address 192.168.0.220; } 

从/ var / log / syslog输出缺less客户端主机名：

 Jun 21 22:37:37 drake dhcpd[1627]: DHCPDISCOVER from ea:25:63:d9:6c:10 via eth1 Jun 21 22:37:37 drake dhcpd[1627]: DHCPOFFER on 192.168.0.220 to ea:25:63:d9:6c:10 via eth1 Jun 21 22:37:37 drake dhcpd[1627]: DHCPREQUEST for 192.168.0.220 (192.168.0.254) from ea:25:63:d9:6c:10 via eth1 Jun 21 22:37:37 drake dhcpd[1627]: DHCPACK on 192.168.0.220 to ea:25:63:d9:6c:10 via eth1 

有没有办法使dhcp-server在日志文件中显示客户端主机名，即使mac地址链接到静态IP？

我真的认为我之前做过这件事……据我所知，在当时的旧式Slackware服务器上，这样做效果很好。

运行isc-dhcpserver的服务器正在运行Ubuntu服务器16.04，并应用了最新的更新。
