新手在配置中出现问题(FTP DHCP)

qq2006_linux

1)
浏览器能够通过ftp://127.0.0.1 登录
但在#ftp 127.0.0.1 就会出现connection refuse ?
还有ftp://172.16.40.* 就不能够登录 我想应该是我把匿名服务没有设置好
可是用户名ftp nobody 都存在

2)
DHCP在启动的时候总是出现一下信息

dhcpd failed. The error was: /etc/sysconfig/dhcpd: line 2: 0: command not found

其中"/etc/dhcpd.conf line 4: subnet 172.16.40.*  netmask 255.255.255.0: bad subnet number/mask combination.
subnet 172.16.40.* netmask 255.255.255.0 "这段是在我自己设置中出现的,之前这段提示还是存在的 只是不存在这一段

谢谢

dhcp

你的dhcp文件配置有误，贴出来看看

qq2006_linux

[root@wangq ~]# /etc/rc.d/init.d/dhcpd status
/etc/sysconfig/dhcpd: line 2: 0: command not found
dhcpd 已停

我一般使用的webmin 配置
更加奇怪的是安装了webmin后 每次重新启动 都要重新解压才能进入
http://localhost:10000/

能顺便给我解决一下这个问题么

以下就是dhcpd.conf 请指教

ddns-update-style interim;
ignore client-updates;

subnet 172.16.40.253 netmask 255.255.255.0 {
        authoritative;
        # --- default gateway
        option routers 172.16.40.254;
        option subnet-mask 255.255.255.0;
        option nis-domain "domain.org";
        option domain-name "domain.org";
        option domain-name-servers 202.98.96.68;
        option time-offset -18000;
        range dynamic-bootp 172.16.40.0 172.16.40.254;

        max-lease-time 43200;
        # we want the nameserver to appear at a fixed address

因为机器的其他原因  我重新安装了系统
我所作的步骤是 先找到dhcpd.conf.sample 复制后放在/etc下 重命名为dhcpd.conf
然后到服务下启动还是成功的
但在终端使用/etc/rc.d/init.d/dhcpd start 没有反应
于是 我重新启动了网络 再输入就出现下面的信息  郁闷.........




[root@localhost ~]# /etc/rc.d/init.d/dhcpd start

No subnet declaration for eth0 (172.16.40.253).
** Ignoring requests on eth0.  If this is not what
   you want, please write a subnet declaration
   in your dhcpd.conf file for the network segment
   to which interface eth0 is attached. **


Not configured to listen on any interfaces!

subnet 172.16.40.253 netmask 255.255.255.0 {

改成 subnet 172.16.40.0 netmask 255.255.255.0 {

试试看

qq2006_linux

太感谢了  问题解决了

只是我还是不明白 为何要这样改
非常感谢 !!!

wwdjs

subnet 172.16.40.0 netmask 255.255.255.0 是定义一个你要分配地址的网段
而 range dynamic-bootp 172.16.40.0 172.16.40.254  是你要分配地址的范围
所以你的客户机自动获取ip地址的范围是从172.16.40.1~172.16.40.254

qq2006_linux

哦 明白了

谢谢 非常感谢！
