搞不定DHCP client ,来求助下!

IP地址获取不了

用VMWARE安装的LFS 6.3,现在准备把网卡设置成DHCP方式自动获取IP，参考了BLFS的手册，安装了blfs-bootscripts-20080816,运行：make install-service-dhclient

并且生成了/etc/sysconfig/network-devices/ifconfig.eth0/dhclient和/etc/dhclient.conf,启动机器的时候也没提示错误，但运行ifconfig 看不到IP，系统日志错误如下：

Mar 2 16:47:46 mylinux dhclient: execve (/sbin/dhclient-script, ...): No such file or directory
Mar 2 16:47:46 mylinux dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67
Mar 2 16:47:46 mylinux dhclient: execve (/sbin/dhclient-script, ...): No such file or directory
Mar 2 16:47:46 mylinux dhclient: bound to 192.168.153.129 -- renewal in 707 seconds.


系统里找不到/sbin/dhclient-script

老李飞刀

怎么不搞定法也要说一下吧？

就是eth0 获取不了IP

cqcya

你安装的是哪一个客户端？dhcpcd-4.0.11 还是DHCP-3.0.6

cqcya

Finally, as the root user create the /etc/sysconfig/network-devices/ifconfig.eth0/dhcpcd configuration file using the following commands. Adjust appropriately for additional interfaces:

install -v -d /etc/sysconfig/network-devices/ifconfig.eth0 &&
cat > /etc/sysconfig/network-devices/ifconfig.eth0/dhcpcd << "EOF"
ONBOOT="yes"
SERVICE="dhcpcd"
DHCP_START="<insert appropriate start options here>"
DHCP_STOP="-k <insert additional stop options here>"

# Set PRINTIP="yes" to have the script print
# the DHCP assigned IP address
PRINTIP="no"

# Set PRINTALL="yes" to print the DHCP assigned values for
# IP, SM, DG, and 1st NS. This requires PRINTIP="yes".
PRINTALL="no"
EOF

我装的是DHCP-4.0，不过文档上不是说，做DHCP-CLIENT不用装DHCP 的啊

我就是参照文档，先下载 blfs-bootscripts-20080816 ，然后make install-service-dhclient，再创建dhclient

install -v -d /etc/sysconfig/network-devices/ifconfig.eth0 &&
cat > /etc/sysconfig/network-devices/ifconfig.eth0/dhclient << "EOF"
ONBOOT="yes"
SERVICE="dhclient"
DHCP_START="-q <add additional start parameters here>"
DHCP_STOP="-q -r <add additional stop parameters here>"

# Set PRINTIP="yes" to have the script print
# the DHCP assigned IP address
PRINTIP="no"

# Set PRINTALL="yes" to print the DHCP assigned values for
# IP, SM, DG, and 1st NS. This requires PRINTIP="yes".
PRINTALL="no"
EOF

DHCP_START="-q <add additional start parameters here>"
DHCP_STOP="-q -r <add additional stop parameters here>"
“<add additional start parameters here>"这个值你修改了吗？

改了，我两项都没有设置，空值

聚焦深空

CBLFS 使用的是 dhcp-3.1.0
http://cblfs.cross-lfs.org/index.php/Dhcp

BLFS 使用的是 dhcp-3.0.6
http://www.linuxfromscratch.org/blfs/view/stable/server/dhcp.html

您可以考虑一下，为什么他们都不用 dhcp-4.0？

您要是执意使用 4.0 版，不妨搜搜偶的帖子。
具体处理很简单，但偶是完全自定义的系统，您要自己修改使其适合您的系统。
