DHCPD 不允许文件名选项中包含冒号

DHCPD 不允许文件名选项中包含冒号

由于某种原因,参数tftpboot中的冒号不起作用:filename

group {
  filename "node7:linux/pxelinux.0";

  host machine_7a  {
    hardware ethernet 02:01:02:02:01:11;
    fixed-address 192.168.10.8;
  }

  host machine_7b {
    hardware ethernet 02:01:02:02:01:12;
    fixed-address 192.168.10.9;
  }
}

如果我将冒号改为破折号-,远程机器就可以正常进行 tftpboot。您知道为什么参数中的冒号filename不起作用吗?

更新

/var/log/message当我设置为时filename的输出"node7-linux/pxelinux.0"
